How many one thirds are in 7 halves?

pshichka [43]

Hello!

Here's how to solve this question without the use of a calculator.

$7 \times { \frac{1}{2} } = { \frac{7 \times 1}{2} } = { \frac{7}{2} }$

7/2 ÷ 1/3 = ?

Change division to multiplication.

${ \frac{7}{2} } \times { \frac{3}{1} } = { \frac{7 \times 3}{2 \times 1} } = { \frac{21}{2} }$

21/2 = 10.5 ≈ 10 (rounded)

EFGH is a parallelogram find the measure of EG

dezoksy [38]

Answer:

Step-by-step explanation:

We know 4w + 4 = 2w + 22

So lets solve for w and plug it into both equations.

Subtract 4 from both sides

4w = 2w + 18

Subtract 2w from both sides

2w = 18

Divide 2 from both sides

w = 9

Now lets plug in w to one of the equations and multiply it by 2 to get the total length of EG

2[4(9) + 4)] = 80

So the length of EG is 80
