Answer:

x= .31066.... rounded to .31

Step-by-step explanation:

first you take out the exponent (2) by getting the square root of 18 so the equation will be 4x+3=18squared rooted. the primary factors of 18 are 2*3 squared. so instead of 18 put the factors is.so now you will get

4x+3=3^2*2 square rooted.

then you apply the radical rule so square root each of the digits.that will simplify to 4x=3square rooted by 2 divide by 4 on both sides minus 3/4 and if you simplify it should give you the answer

kompoz [17]

Five friends went to see a movie. Each person paid $5.

This is a total of $40.

$62.50 - $40 = $22.50.

We now have $22.50 to divide by 5 people.

So, $22.50/5 = $4.50.

Each person paid $4.50 for popcorn.

Izzy gets a loan of $2,800 with an APR of 3.5% . She will repay the loan in monthly payments for 9 months. To find the total amo
djyliett [7]
First, change percent into decimal value
Percent means per hundred
APR = 3.5%
APR = 3.5/100
APR = 0.035
The APR is 0.035 of the total loan

Second, we need to find interest rate for 9 months
interest rate = 9/12 × 0.035
interest rate = 3/4 × 0.035
interest rate = 0.75 × 0.035

Third, determine what to put into calculator
She can put it like this
interest = interest rate × total loan
interest = 0.75 × 0.035 × 2,800

Or she can put it like this
interest = 0.02625 × 2,800
