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.

Wo groups are hiking at about the same speed. Mario's group hikes for 2.5 hours. Seema's group hikes for 4.7 hours and covers 8.8 more miles. How fast are the hikers going? Solve the equation below to find out. 4.7x = 2.5x + 8.8

Answers

Answer:

x = 4 miles per hour

Step-by-step explanation:

4.7x = 2.5x + 8.8

Collecting like terms

4.7x - 2.5x = 8.8

2.2x = 8.8

x = 8.8 / 2.2

x = 4 miles per hour

You spin the spinner and flip a coin. Find the probability of the compound event.


The probability of spinning a prime number and not flipping heads is...

Answers

Answer:

3/10 or 0.3

Step-by-step explanation:

The numbers in the spinners are given to be:

{1,2,3,4,5}

Total number of outcomes are: 5

On spinning the spinner, the outcomes which are prime are:

{2,3,5}

Hence, the probability that a prime number is obtained is:

3/5

Also, the probability that a head is not obtained i.e. a tail is obtained is:

1/2

Hence, the compound probability of spinning a prime number and not flipping head is:

3/10 or 0.3
