x+3.5=2x+2/2
x-2x+3.5=1
-x=(-3.5)+1

A new business borrows $320,000 at a yearly simple interest rate of 7%. The total amount the
company repays for the loan and interest is $678,400. How long did it take to pay off the loan?
Answer:
16 years
Step-by-step explanation:
Annual interest payment is 7% * 320k = 22,400
Total interest is 678400-320000=358400
358400/22400=16
The number of years that it takes to pay off the loan will be 16 years.
What is simple interest?Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.
The formula for interest is written as,
I = (PRT)/100
Where P is the principal, R is the rate of interest, and T is the time.
A new business borrows $320,000 at a yearly simple interest rate of 7%. The total amount the company repays for the loan and interest is $678,400. Then the equation is given as,
P + I = A
$320,000 + ($320,000 x 7 x T) / 100 = $678,400
$22,400 T = $358,400
T = 16 years
The number of years that it takes to pay off the loan will be 16 years.

Answer:
=90[tex]x^{2}[/tex]+2x+3
Step-by-step explanation:
Let's simplify step-by-step.
2[tex]x^{2}[/tex] + 82[tex]x^{2}[/tex] + 8 − ( −6[tex]x^{2}[/tex] − 2x + 5 )
Distribute the Negative Sign:
= 2[tex]x^{2}[/tex] + 82[tex]x^{2}[/tex] + 8 + − 1 ( − 6[tex]x^{2}[/tex] − 2x + 5 )
= 2[tex]x^{2}[/tex] + 82[tex]x^{2}[/tex] + 8 + − 1( − 6[tex]x^{2}[/tex] ) + − 1 ( −2x ) + ( − 1 ) ( 5 )
= 2[tex]x^{2}[/tex] + 82[tex]x^{2}[/tex] + 8 + 6[tex]x^{2}[/tex] + 2x + − 5
Combine Like Terms:
= 2[tex]x^{2}[/tex] + 82[tex]x^{2}[/tex] + 8 + 6[tex]x^{2}[/tex] + 2x + −5
= ( 2[tex]x^{2}[/tex] + 82[tex]x^{2}[/tex] + 6[tex]x^{2}[/tex] ) + ( 2x ) + ( 8 + − 5 )
= 90[tex]x^{2}[/tex] + 2x + 3

The diameter of a circle is 20 ft. Find its area in terms of 7.
Step-by-step explanation:
The circumference of a circle is (pie) X d (d = diameter) or 2(pie) r ( r = radius)
The circumference of a circle of 20 foot diameter = (22/7) x 20 =
440/7 = 62.86 foot
If AC = 30 and AE = 3x + 3, then x = ________.
If DC = 6x + 1, BC = 2y + 2, AB = 25, and AD = 14, then x = _______ and y = _______.
Answer and Step-by-step explanation:
Part 1:
AE is equal to EC
3x + 3 + 3x + 3 = 30
6x = 24
x = 4
DC is equal to AB
6x + 1 = 25
6x = 24
x = 4
BC is equal to AD
2y + 2 = 14
2y = 12
y = 6

Step-by-step explanation:
GHJ looks like it on 112 degrees.
IHJ is an acute angle so smaller than 90 degrees. I cant see the numbers there but I'm guessing its about 68 degrees.
GHJ + IHJ= 180
they should equal 180 degrees when added together.
Mei runs 60.36 miles in 4 weeks. If she runs 3 days each week, what is the average distance she runs each day?
Answer:
15.09
Step-by-step explanation:
She ran only 12 times every 4 weeks, so we divide 60.36 by 4 which then becomes the result of running 3 days a week which means the answer is 15.09 because 15.09 multiplied by 4 is 60.36.
Answer:
The answer is 15.09.

What is the approximate area of a circle with the diameter of 20cm in square centimeters (use 3.14 for pie(
Answer:
314cm
Step-by-step explanation:
the area formular for a circle is a=pi(r)^2. Using this information we can plug in the numbers...
3.14(10)^2. Next square 10 to get 3.14*100. Then you get 314 which is the answer. The reason I used 10 is because the diameter is half of the radius so half of 20 would be 10.
