We need to solve for x, start with distribution.
8x - 8
Then find out a number times 8 minus 8 that equals -4 times a number.

Find the difference between 7 1/2 and 2 3/4

NNADVOKAT [17]

Answer:

4 $\frac{3}{4}$ or 4.75

Step-by-step explanation:

first we're going to convert the number into improper fractions.

7 $\frac{1}{2}$ = $\frac{15}{2}$ and 2 $\frac{3}{4}$ = $\frac{11}{4}$

For subtracting it is suitable to adjust both fractions to an equal denominator, so we're going to multiply $\frac{15}{2}$ x2, it'll equal the same number.

So now we have $\frac{30}{4}$ - $\frac{11}{4}$ , 30-11= 19.

$\frac{19}4}$ simplified is, 4 $\frac{3}{4}$ .

As you can see I also added 4.75 as an answer, that's if the answer must be a decimal.

I hope this helps you!

C=2(y-k) solve for y

marshall27 [118]

Answer:

$\blue{y = \dfrac{C + 2k}{2}}$

Step-by-step explanation:

$C = 2(y - k)$

$C = 2y - 2k$

$C + 2k = 2y$

$\dfrac{C + 2k}{2} = y$

$y = \dfrac{C + 2k}{2}$
