In order to combine, you have to multiply the top equation by 2
so you get
8g + 10h = 8
8g - 10h = 4
---------------
16g = 12
g = 3/4 --> plug it in to solve for h
8(3/4)-10h = 4
6-10h=4
10h=2
h=1/5
Your result: g=3/4, h=1/5
Answer:
A = $13,660.81
Step-by-step explanation:
P (principal) = $4,800.00
I (interest) = $8,860.81
First, convert R as a percent to r as a decimal
r = R/100
r = 6.2/100
r = 0.062 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 4,800.00(1 + 0.062/4)(4)(17)
A = 4,800.00(1 + 0.0155)(68)
A = $13,660.81
Answer:
5 11/12 cups of melon
Step-by-step explanation:
The cups of melon he puts in the fruit salad is:
Number of cups of orange melon + Number of cups of green melon
= 3 1/4 cups + 2 2/3 cups
3 + 2 + (1/4 + 2/3)
The Least common denominator is 12
5 + (3 × 1 +4 × 2/12)
5 + (3 +8/12)
5 11/12 cups
Therefore, Jason put in 5 11/12 cups of melon in the fruit salad.
27/36 = n/4
27*4 = 36n
108 = 36n
108/36 = 36n/36
n = 3
