10+5-7=3y<br><br> -10x+5x+5=-15<br><br> 3x+2x-4x+10<br><br> pre algebra 8th grade math
jasenka [17]

Answer:

1) y=8/3=2 2/3   2) x=4    3) x+10

Step-by-step explanation:

1) 10+5-7=3y

Calculate the sum or difference.

8=3y

Swap the sides of the equation.

3y=8

Divide both sides by 3.

y=8/3=2 2/3

2) -10x+5x+5=-15

Collect like terms.

-5x+5=-15

Move the constant to the right-hand side and change the sign.

-5x=-15-5

Calculate the difference.

-5x=-20

Divide both sides by -5.

x=4

3) 3x+2x-4x+10

Collect like terms.

(3+2-4)x+10

Calculate the sum or difference.

1x+10

When the term has a coefficient of 1, it doesn't have to be written.

x+10

Hope this helps :)

in the usa, the shoe sizes or men are approximated by the equation 3f-s=24, where f represents the length of the foot in inches
Otrada [13]

Answer:

x intercept = 8

y intercept = -24

Step-by-step explanation:

In the USA, the shoe sizes or men are approximated by the equation 3f-s=24, where f represents the length of the foot in inches and s represents the shoe size.

<u>When we represent this equation using a graph, we mark the independent variable on the x axis and the dependent variable on the y axis.</u>

Here the foot length is the independent variable and the shoe size is the dependent variable. Hence we take foot length on x axis.

To get x intercept put y=0, f = \frac{24}{3} = 8 inches .

This is the point from which where we start our shoe size.

The y intercept , s = -24.
