Answer:

Distribute

When you have an equation like this, distribute first and then add or subtract like terms to solve for x.

Hope this helps!!

Well, you need to find out what x is equal to, if anything.

The first step to completing it, from what I've learned, is to do the problem that is in parenthesis first.

Hope this helps, sorry if not-

Hi Brainiac

7/8 =?/48

Let's replace the unknown place by x

7/8 = x/48

Cross multiply

(7)(48)= (X)(8)

336 = 8x

Flip it

8x = 336

Divide both sides by 8

8x/8 = 336/8

x= 42

The answer is C

Now if you wanna see if the answer is good just replace 42 in blank space

7/8 = 42/48

Now didivde 7 by 8 and divide 42 by 48

7/8= 0.875

42/48= 0.875

The answer C is correct

I hope that's help:)

If you have questions please let me know :)

Answer:

See below ~

Step-by-step explanation:

Problem 9

h(1/8) = 3(1/8) + 1/4
h(1/8) = 3/8 + 2/8
h(1/8) = 5/8

Problem 10

Q(k) = k - 3 / 2
-4 = k - 3 / 2
-8 = k - 3
k = -8 + 3
k = -5

Answer:

$m=\frac{-3}{2}$

Step-by-step explanation:

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Simply plug in 2 coordinates into the slope formula to find slope m:

$m=\frac{-1-2}{2-0}$

$m=\frac{-3}{2}$

What is the missing value of (x,2) and (6,3); m=1/2 using the slope?

siniylev [52]

$\bf (\stackrel{x_1}{x}~,~\stackrel{y_1}{2})\qquad (\stackrel{x_2}{6}~,~\stackrel{y_2}{3}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{3}-\stackrel{y1}{2}}}{\underset{run} {\underset{x_2}{6}-\underset{x_1}{x}}}~~ = ~~\stackrel{\stackrel{m}{\downarrow }}{\cfrac{1}{2}}\implies \cfrac{1}{6-x}=\cfrac{1}{2}\implies 2=6-x \\\\\\ x+2=6\implies x = 4$
