Let x=annual interest rate of 18000 investment.
Then
18000*x - 9000(x-0.006)=648
Solve for x
18000x-9000x+9000*0.006=648
9000x=648-54=594
x=594/9000=0.066
Answer:
the annual interest rate of the 18000 investment is 6.6%
the annual interest rate of the   9000 investment is 6.0%

elena-14-01-66 [18.8K]
The answer would be $74 because you would need to multiply the number of socks Hana ordered by the cost and multiply the amount Charlie ordered by the cost. Now you would add the two amounts together and also add 4 for the 2 shipping orders.

The m6 = (11x + 8)° and m7 = (12x – 4)° What is the measure of 4? m4 = 40° m4 = 48° m4 = 132° m4 = 140°
bezimeni [28]
M< 6 = m< 7 (vertical angles)
11x + 8 = <span>12x – 4
12x - 11x = 8 + 4
 x = 12
so
m< 6 = </span>11x + 8 
m< 6 = 11(12) + 8
m< 6 = 132 + 8
m< 6 = 140

m<4 = 180 - m<6
m<4 = 180 - 140
m<4 = 40

answer

<span>m<4 = 40</span>

Solve for p-1=5p+3p-8
kifflom [539]
P-1 = 5p+8p-8
p-1 = 13p-8 (collect like terms)
p+7 = 13p (add 8 to both sides)
7 = 12p (minus p from both sides)
7/12 = p (divide both sides by 12)
p = 7/12
