Answer:
10(x + 3) - (-9x - 4) = x - 5+ 3
10x+30+9x+4=x-2
19x+34=x-2
19x-x= -2-34
18x=-36
x= -2
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
The price of silver has increased by 25% per year from 2000. In the year 2000, Harry bought a silver bowl for $170.
<u>To calculate the price of the silver bowl after x years, we need to use the following formula:</u>
<u></u>
F(x)= PV*(1+g)^x
F(x)= future value
PV= present value
g= growth rate
x= number of years
<u>For example, we determine the value of the coin after 10 years:</u>
F(x)= 170*(1.25^10)
F(x)= $1,583.25
I know that from least to greatest is C
The decimal as a percent is A
36% as as a fraction is C
8% as a decimal is A
7/8 as a percent is B
110/11 is essentially 110 divided by 11. Therefore, 110 divided by 11 is 10/1, which equals 10.
Answer:
a. The student's conclusion is incorrect because the solution to the system of equations 3x + 4y = 32 and 5x + 5y = 50 is (8, 2).
Step-by-step explanation:
The second equation needs to be ...
5x +5y = 50
because the wording "short of $18" means that the actual cost of that purchase would be $18 more than the $32 that Harry had. 18+32 = 50.
The only answer choice that shows this as the second equation is choice A.

In fact, the solution to the system of equations is (8, 2), as can be seen in the graph below.
