Let Q= the number of quarters and D= the number of dimes.
Q+D= 40 coins
0.25Q+0.1D= $7.75
Rewrite equation 1 as: D = 40-Q and substitute into equation 2
0.25Q+0.1(40-Q)= 7.75 Simplify the left side
0.25Q+4-0.1Q= 7.75 Subtract 4 from both sides
0.25Q-0.1Q= 3.75 Convime like terms on left side
0.15Q= 7.75 Divide both sides by 0.15
Q=25 and D= 40-Q
D= 40-25 which is 15
So Jenna had 25 quarters and 15 dimes.
<span>To check multiply 25 x 25 and 15x10 which equals 625 and 150 this equals 775 so this is 7.75</span>
Answer: 121.126
<u>Step-by-step explanation:</u>
8.5 3
x <u>1 4.2</u>
1 7 0 6 (2 x 853)
3 4 1 2 0 (40 x 853)
<u>8 5 3 0 0</u> (100 x 853)
12 1 1 2 6
12 1 .1 2 6 (moved the decimal 3 places)
Answer:
12 p - 8 p, 4p ( 3 - 2)
Step-by-step explanation:
p = equal the number of ounces of pasta salad in one container
then 12 × p = 12 p in 12 containers
the students finished the pasta salad in 8 containers which equals = 8 p
the number of ounces of pasta left = 12 p - 8 p
b) using the distributive property for example a ( b + c) = ( a×b) + (a ×c)
12 p - 8 p = 4p ( 3 - 2)
As the graph approach negative infinity the graph move to positive infinity as the graph approach positive infinity the graph move to negative infinity
No its sss because you have no given angles only sides
