Answer:

1. 2x=5

Divide both by 2, x=2.5

2. y+1.8=14.7

Subtract 1.8 from both sides to isolate the variable, x=12.9

3. 6=1/2z

Multiply each side by 2 to isolate the variable, 12=z

4. 3 1/4 = 1/2+w

Isolate the variable by subtracting 1/2 to both sides, 2 3/4 = w

5. 2.5t=10

Divide each side by 2.5 to isolate the variable, t=4

Suppose $7,558.20 in interest was earned after $12,350 was invested at a simple interest rate of 7.65%. How long (in years) was

vladimir1956 [14]

The formula is
I=prt
I interest earned 7558.20
P principle 12350
R interest rate 0.0765
T time?
Solve the formula for t by dividing both sides by pr to get
T=I/pr
T=7,558.20÷(12,350×0.0765)
T=8 years

Hope it helps!
