As per the distance concept, the speed of the buses are 79 km/h and 69km/h if the two buses leave a station at the same time and travel in opposite directions.

Distance

Distance refers the physical length or an approximation based on other physics or common usage considerations.

Given,

Two buses leave a station at the same time and travel in opposite directions. One bus travels 10 slower than the other. If the two buses are 276 miles apart after 2 hours,

Here we need to find the rate of each bus.

Let us consider the speed of the first bus is x km/h.

Then the speed of the other bus = (x - 10) km/h

We know the formula of distance is,

Distance = time × speed

When we combined speed then we get,

=> x + x - 10 = (2x - 10) km/h

=> 2(2x - 10) =276

When we expand the equation, then we get,

4x - 40 = 276

4x = 316

After calculating,

x = 79 km/h

The speed of first bus x = 79 km/h

Speed of the second bus = x - 10 = 79 - 10 = 69 km/h

Therefore, the speed of the buses are 79 km/h and 69/km/h if the two buses leave a station at the same time and travel in opposite directions.

ANSWER

B) y = 1/2x - 6

EXPLANATION

We have that the line passes through (6 -3) and has a slope of 1/2.

To find the point-slope form of the equation, we have to use the formula:

where m = slope = 1/2

(x1, y1) = (6, -3)

So, we have:

y - (-3) = 1/2 (x - 6)

y + 3 = 1/2 x - (1/2 * 6)

y + 3 = 1/2 x - 3

=> y = 1/2x - 3 - 3

y = 1/2x - 6

120 children and 120 adults were admitted to the amusement park if the admission fee collected was $1980.00

The number of children and adults that entered the park can be calculated using linear equations.

Considering x to be the number of adults and y to be the number of children;

As 240 people entered the park, therefore;

x + y = 240

As the fee for children is $3.50 and for adults is $13, therefore;

13x + 3.50y = 1980

Determining the value of y in the first equation;

x + y = 240

y = 240 - x

Putting this value of y in the second equation;

13x + 3.50y = 1980

13x + 3.50(240 - x) = 1980

13x + 840 - 3.50x = 1980

9.5x = 1980 - 840

9.5x = 1140

x = 1140 / 9.5

x = 120

To determine the value of y, we Substitute this value of x in the first equation;

y = 240 - x

y = 240 - 120

y = 120

Hence, 120 children and 120 adults entered the park if the admission fee for children was $3.50 and for adults was $13.00

Answer:

Touchdowns: 6

Field goals: 3

PATS: 5

Step-by-step explanation:

6*6 = 36

3*3 = 9

5*1 = 5

9+5+36 = 50 points

6+3+5 = 14 scored times

Answers:

6 touchdowns (TD)

3 field goals (FG)

5 points after touchdown (PAT)

===============================================

Explanation:

Acronyms used in football

Define the following variables

"They had 3 more touchdowns than field goals", so,

TD = FG + 3

x = y + 3

They scored 14 times which means we can say

x+y+z = 14

Let's look at the point breakdown per type of score

Then we can add up those expressions to get us to 6x+3y+1z = 50 points total. This is the same as saying 6x+3y+z = 50.

--------------------------

Here's our system of equations

x = y+3

x+y+z = 14

6x+3y+z = 50

Let's replace each x with y+3 in the second equation. Then solve for z.

x+y+z = 14

y+3+y+z = 14

2y+z = 14-3

2y+z = 11

z = 11-2y

Now replace every x with y+3 in the third original equation

6x+3y+z = 50

6(y+3)+3y+z = 50

6y+18+3y+z = 50

9y+z = 50-18

9y+z = 32

Then plug in z = 11-2y and solve for y

9y+z = 32

9y+11-2y = 32

7y+11 = 32

7y = 32-11

7y = 21

y = 21/7

y = 3 is the number of FGs scored

Use this to find z

z = 11-2y

z = 11-2(3)

z = 11-6

z = 5 is the number of PATs scored

Now let's find x

x = y+3

x = 3+3

x = 6 is the number of TDs scored

--------------------------

Checking the answers:

x+y+z = 6+3+5 = 9+5 = 14 times they scored

6x+3y+z = 6*6+3*3+5 = 36+9+5 = 50 points scored

There are 3 more TDs than FGs since x = y+3 leads to 6 = 3+3 which is a true statement.

All three original equations we set up for the system of equations are true. Therefore, the final answers are confirmed.

From the expression we can see that it is translated 3 units downwards from the origin.

In order to find how many pounds are in each bag, we just need to divide the total amount of blueberries by the number of bags.

So we have:

So in each bag there are 1/16 pounds of blueberry.

The price of 1 yard of blue fabric and 1 yard of green fabric is obtained by solving the system of linear equations and it is $8

Let

x = price of blue fabric per yard

y = price of green fabric per yard

"The blue fabric costs $2 more per yard than the green fabric" means:

x = y + 2  (Equation 1)

" LaTanya buys 6 yards of blue fabric and 9 yards of green fabric and pays $57" means:

6x + 9y = 57  (Equation 2)

Substitute equation 1 into equation 2:

6x + 9y = 57

6 (y + 2) + 9y = 57

6y + 12 + 9y = 57

15 y = 45

y = 3

Substitute y = 3 into equation 1

x = 3 + 2 = 5

Hence, the price of blue fabric is $5 per yard while the green fabric is $3 per yard.

The price of 1 yard of blue fabric and 1 yard of green fabric = x + y = 3 + 5 = $8

Complete question:

LaTanya buys 6 yards of blue fabric and 9 yards of green fabric. The blue fabric costs $2 more per yard than the green fabric. She pays a total of $57. What would be the combined cost of 1 yard of blue fabric and 1 yard of green fabric?

a. The expected value is 0.40

b. The standard error is 0.0024

Given that:

Sample size, n=100

Population proportion, p=0.40

a) The expected value of the sample proportion is defined as:

E(^p)=p

now,

E(^p)=0.40

b) The standard error of the sample proportion is defined as:

SE(^p) = √p(1-p)/n

SE(^p) = √0.40(1-0.40)/100

SE(^p) = 0.0024

c) The sampling distribution of the sample proportion is normally distributed with the expected value of the sample proportion of 0.40.

Therefore,

E(^p) = 0.40

d) The central limit theorem states that the sample statistic (sample proportion) tends to the population parameter (population proportion) as the sample size tends to infinity (OR n→∞).

use the property’s of equality to solve

Step-by-step explanation:

Use the properties of equality to solve, is not a step when we are solving an equation using distributive property.

Distributive property:- In general,

      distribute means to divide something or give a share or part of something. According to this property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

             ex:-   a(b+c)=ab+ac

                       a(b-c)=ab-ac  ,also valid true for division

                  (b+c)/a = b/a + c/a

Steps involved while solving equations

1. If you see parenthesis, with more than one term inside, then distribute first.

2. Rewrite your equations with like terms together. Take the sign in front of each term.

3. Combine like terms.

The equation of the line is y = -3x + 8.

The slope of a line, or angle between it and the horizontal, is stated numerically. The slope of a line, ray, or line segment in analytical geometry is the ratio of its vertical to horizontal distance between any two locations ("slope equals rise over run").

Given,

x1 = 1

y1 = 5

m = -3

From,

y-y1 = m(x-x1) (x-x1) (x-x1)

y - 5 = -3(x - 1) (x - 1) (x - 1)

y-5 = -3x + 3

y = -3x + 8

Mathematicians frequently use the substitution method to resolve an equation system. With this method, you solve the equation for the first variable first, and then plug the answer into the second equation.

what is a linear equation in two variables?

When an equation is written in the form axe + by + c=0 and the coefficients of x and y, i.e., a and b, respectively, are not equal to zero and the greater of the two numbers is four times the smaller number minus 5, that equation is said to be linear in two variables.

Let's assume that "x" is the smaller number, making "4x-5" the greater number. The requirement that the difference between the two numbers be 16 is also included.

thus,

4x - 5 - x = 16
3x -5 = 16
3x = 16 +5
3x =21
x = 21/3
