Solve for x. 2 1/2x−3/4(2x+5)=3/8

RUDIKE [14]

$2 \frac{1}{2}x- \frac{3}{4}(2x+5)= \frac{3}{8}$
$2 \frac{1}{2}x- \frac{6}{4}x- \frac{15}{4}= \frac{3}{8}$
$( 2\frac{1}{2}- \frac{6}{4})x= \frac{3}{8}+ \frac{15}{4}$
$( \frac{5}{2}- \frac{6}{4})x= \frac{3}{8}+ \frac{15}{4}$
$( \frac{10}{4}- \frac{6}{4})x= \frac{3}{8}+ \frac{30}{8}$
$\frac{4}{4}x= \frac{33}{8}$
$x= \frac{33}{8}=4 \frac{1}{8}$

What is the value of g?<br> -5+7g=3g+ 9

Xelga [282]

Answer:

g = 7/2

Step-by-step explanation:

-5 + 7g = 3g + 9

~Add 5 to both sides

7g = 3g + 14

~Subtract 3 to both sides

4g = 14

~Divide 4 to both sides

g = 14/4 or g = 7/2

What are the steps on how do you divide fractions using area models?

topjm [15]

Use keep, change, flip!
Ex: 1 / 3
— —
2 4

Keep the 1/2
Change the division sign to a multiplication sign
Flip the 3/4 to be 4/3

1 X 4
— —
2 3

Then, multiple and simplify as usual!

1 X 4= 4
2 X 3= 6

4 = 2
— —
6 3

The answer would be 2
—
3

Hope this helps, brainliest please! :)
