To expand, you just take the 5 and multiple by each individual factor.
10 x 5x + 5y x 10
5 quarters, 15 dimes
q + 10 = d
0.25q + 0.1d = 2.75
0.25q + 0.1(q + 10) = 2.75
0.25q + 0.1q + 1 = 2.75
0.35q = 1.75
q = 5
Check:
0.25(5)+ 0.1(15)= 2.75
1.25 + 1.5 = 2.75
2.75 = 2.75 :)
Answer:
n = 5.4
Step-by-step explanation:
Equation: 4n = 21.6
To solve this equation for n, divide both sides by 4 to get n by itself.
<u />
<u>Step 1: Divide both sides by 4</u>
4 * n / 4 = 21.6 / 4
n = 5.4
Answer: n = 5.4
