DeAngelo rode his bike at a rate of 15 miles per hour. At that rate, how far could he ride in three hours?

Answers

Answer 1
Since the formula for finding distance is d=r(t), it would be d=15(3). So the distance would be 45 miles in 3 hours.
Answer 2
15 mph so in three hours, he could ride 15*3=45 miles in 3 hours

7. f(x) = 2x + 5 What is the value of x if f(x) = 25 ?

Answers

Answer:

x=10

Step-by-step explanation:

set the 2 equations equal to each other

25=2x+5     -> subtract 5

20=2x         -> divide by 2

10=x            ->answer!

Hope that helps!

Answer:

x = 10

Step-by-step explanation:

f(x) equals both 25 and 2x + 5, so set the equations equal to one another and solve for x.

2x + 5 = 25

2x = 20

x = 10

Plug in what you got for x to check if it is right

2(10) + 5 = 25

20 + 5 = 25

25 = 25

Carolyn borrowed $38,500 to pay
for college. If the interest rate is
3.2%, how much total will she
have paid after 10 years?

Answers

Answer:

$50820

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3.2%/100 = 0.032 per year,

then, solving our equation

I = 38500 × 0.032 × 10 = 12320

I = $ 12,320.00

The simple interest accumulated

on a principal of $ 38,500.00

at a rate of 3.2% per year

for 10 years is $ 12,320.00.
