7(h-4) = 2h + 17 distribute to get:
7h - 28 = 2h + 17 subtract 2h from both sides to get:
5h - 28 = 17 add 28 to both sides to get:
5h = 45 divide 5 from both sides to get:
h = 9
If you are just dividing percent's, then each grade would have 12.5 percent.
Answer: 5 cookies
Step-by-step explanation: 8 + .4c = 2.5 + 1.5c
8 + 0.4c = 2.5 + 1.5c
8 · 10 + 0.4c · 10 = 2.5 · 10 + 1.5c · 10
80 + 4c = 25 + 15c
4c = 15c - 55
4c - 15c = 15c - 55 - 15c
-11c = -55
c = 5
I=PRT
I=interest
P=initial amount
R=rate in decimal
T=time in years
given
P=5523
R=4.99%=0.0499
T=7
I=(5523)(0.0499)(7)
I=1929.1839
round
$1929.18 interest earned
Answer:
$110.70
Step-by-step explanation:
<em>I=PRT</em>
P (principal)=360
R(rate)=12.3%
T(time)=30 months (2 and half years)
I=360*12.3%*2.5
=$110.70
Just to note 12.3% is also 0.123 we sometimes change it into a decimal.
