Answer:
32.50
Step-by-step explanation:
It is simple. You need to know the basics of money, fractions, and well... Math! :)
if you take 13 and multiply it by 2 you get 26
Take the 26 and put it aside -------------> 26
divide 13 in half. that would be 6.50
6.50 + 6.50 = 13
Now get the 26 --------------------------> 26
and add 6.50 to 26.
That would be 32.50!

Answer:
1.5
Step-by-step explanation:
The scale factor can be found by dividing the side length from triangle ABC by the corresponding side length from triangle ABC
so the scale factor would be equal to
12/8 and 9/6
9/6 = 1.5
12/8 =1.5
so we can conclude that the scale factor is 1.5
Answer:
The number of subscription will be 26,655 in 2022.
Step-by-step explanation:
In 2005, the number subscription is 110,000 and it is decreased at a rate 8% per year.
After 1 year number of subscription is 110,000- 8% of 110,00
=110,000(1-8%)
After 2 years number of subscription is 110,000(1-8%) -8% of 110,000(1-8%)
=110,000(1-8%)(1-8%)
=110,000(1-8%)²
After 2 years number of subscription is 110,000(1-8%)² -8% of 110,000(1-8%)²
=110,000(1-8%)²(1-8%)
=110,000(1-8%)³
....
and so on.
After t year the number of subscription is
t= 2022-2005=17 years
≈26,655
The number of subscription will be 26,655 in 2022.
Make the denominators the same number. Then do the problem as you would regularly without fractions
Answer: 8 inches
Solving Steps:
x(x + 6) = 112
x^2 + 6x = 112
x^2 + 6x - 112 = 0
(x + 14)(x - 8) = 0
x + 14 = 0
x = -14
^^^ reject because distance can’t be negative
x - 8 = 0
x = 8
Check:
x(x + 6) = 112
8(8 + 6) = 112
64 + 48 = 112
112 = 112
