Answer:

Step-by-step explanation:

In order to do this we need to isolate y by performing the inverse operations on the other values like so...

a) 10x + 5y = 20 ... subtract 10x on both sides

5y = 20 - 10x ... divide both sides by 5

y = 4 - 2x ... we can move the 2x to the right to make it into y = mx + b

y = -2x + 4

b) 3x - 2y = 10 + 4x ... subtract 3x on both sides

-2y = 10 + x ... divide both sides by -2

y = -5 - 0.5x ... move -0.5 to the left so it matches y = mx + b

y = -0.5x - 5

Martin uses 5/8 of a gallon of paint to cover 4/5 of a wall. What is the unit rate at which Martin paints in walls per gallon?

Tanya [424]

Remember, (a/b)/(c/d)=(a/b)(d/c)=(ad)/(bc)

so

walls per gallon
4/5 wall per 5/8 gallon
(4/5)/(5/8)
(4/5)(8/5)
32/25
1.28
the unit rate is 1.28 walls per gallon

Question 1 (1 point)

Natalija [7]

Answer: OPTION B.

Step-by-step explanation:

Given the equation $48=-8(\frac{3b}{4}+2)$ you can find an equivalent equation by simplifying it.

You need to remember the multiplication of signs:

$(-)(-)=+\\(+)(+)=+\\(+)(-)=-$

Now you can apply the Distributive property:

$48=\frac{(-8)(3b)}{4}+(-8)(2)\\\\48=\frac{-24b}{4}-16$

Simplifying the equation, you get:

$48=-6b-16$

You can observe that this equivalent equation matches with the equation provided in option B.
