Answer:
= 2.8
Step-by-step explanation:
If the quadrilaterals are similar, then the ratios of corresponding sides will be equal:
KL : QR = 4 : 5.6 = 4 / 5.6 = 5/7
JM : PS = 7 : 9.8 = 7 / 9.8 = 5/7
LM : RS = 3 : 4.2 = 3 / 4.2 = 5/7
This shows that the ratio of KJ : QP = 5/7
KJ : QP = 2 :
= 2 / ![x](https://tex.z-dn.net/?f=x)
Therefore, ![\frac{2}{x}=\frac{5}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7Bx%7D%3D%5Cfrac%7B5%7D%7B7%7D)
cross multiply: 14 = 5![x](https://tex.z-dn.net/?f=x)
Divide both sides by 5:
= 2.8
Answer:
5 containers
Step-by-step explanation:
Alica has 20 cups of soup. She wants to put the soup into 1 quart containers. How many containers does she need?
It is important to note that:
4 cups = 1 quart
Hence, the number of containers she needs is calculated as:
4 cups = 1 quart
20 cups = x
Cross Multiply
4x = 20
x = 20/4
x = 5 quarts containers
Therefore, she needs 5 containers
-1/8(2h + 4) + 1/2 = -7/4
-1/4h - 1/2 + 1/2 = -7/4
-1/4h = -7/4
h = -7/4 * - 4
h = 7 <==
