2. r/5=9/21
r x 21 = 9 x 5
r= 45/21
r= 2.14 ( the answer is B)
3. 4 cups-> 4 dozen
x cups-> 8 dozen
4/x = 4/8
X x 4= 4 x 8
x= 32/4
x= 8 cups
Answer:
25.5 degrees
Step-by-step explanation:
Let the first angle be x degrees, and second angle be y degrees.
<u>Condition # 1:</u>
x = 5y - 13 --------------------(1)
<u>Condition # 2:</u>
x + y = 140 -------------------(2)
Put Eq. (1) in (2)
5y - 13 + y = 140
5y + y - 13 = 140
6y - 13 = 140
Add 13 to both sides
6y = 140 + 13
6y = 153
Divide both sides by 6
y = 25.5 degrees
Now, put the value of y in Eq. (1)
x = 5(25.5) - 13
x = 127.5 - 13
x = 114.5 degrees
<u>So, the measure of smaller angle is:</u>
= 25.5 degrees

Answer:
The store paid 6.67 times the profit made on the jeans
Step-by-step explanation:
Let the amount the clothing store pay for Jean be X
Let the amount the clothing store sells Jean be Y = X ×1.15
The profit (P) made is the difference between amount the clothing store sells Jean and the amount paid for Jean = Y - X = 1.15X - X
Profit (P) = 0.15X
X = P/0.15 = 6.67P
Therefore, the store paid 6.67 times the profit made on the jeans
Answer:
21
Step-by-step explanation:
divide 63 by 3
or
20x3=60
3x1=3
60+3=63
20+1=21 texts
Just multiply the numbers by 1.25
![6 \times 1.25 = 7.5 \\ 12 \times 1.25 = 15](https://tex.z-dn.net/?f=6%20%5Ctimes%201.25%20%3D%207.5%20%5C%5C%2012%20%5Ctimes%201.25%20%3D%2015)
so the height is 15 in
and base is 7.5 in
goodluck
