Solve for b:4 = -2/3(5) + b
saveliy_v [14]

Answer:

\frac{22}{3} = b

or

7\frac{1}{3} = b

(they are the same value, just different ways of writing it)

Step-by-step explanation:

4 = -\frac{2}{3} (5) + b

simplify

4 = -\frac{10}{3} + b

now use inverse operations

4 = -\frac{10}{3} + b

+\frac{10}{3}  +\frac{10}{3}

\frac{22}{3} = b

Why is 2x 3/4 less than 2?
Kipish [7]

Answer & Step-by-step explanation:

It is less because 2 times 3/4 is the same as 2/1 times 3/4 which is 6/4 then simplify it and you get 3/2 which then is 1 1/2.

That is why 2 times 3/4 is less than 2.

Hope that helps ;)

What is the slope of the line represented by the equation 10x - y = 2?
matrenka [14]

Answer:

D. 10

Step-by-step explanation:

To find the slope of the equation, we first need to put the equation into slope-intercept form:

y=mx+b

So first, we need to get y by itself.

10x-y=2

Subtract 10x from both sides.

-y=-10x+2

Then, divide -1 on both sides.

y=10x-2

Slope=10
