Answer:

90/13, 45/13

Step-by-step explanation:

- 2 = x \\ 7x + 9y =  - 45 \\  \\ 7 \times ( - 2)y + 9y =  - 45 \\ y = 9 \\  \\ 7x + 9 \times 9 =  - 45 \\ x =  - 18 \\ (x.y) =  (- 18.9) \\  \\

Simplify:

- 2 \times 9 =  - 18 \\  7 \times ( - 18) + 9  \times 9 =  - 45 \\  - 18 =  - 18 \\  - 45 =  - 45

The population of a U.S. City was at 130,000 in 2014. It grew at a rate of 2.6% per year. What is the population today?
algol13

Answer:

155,588

Step-by-step explanation:

The formula for calculating future value:

FV = P (1 + r)^n

FV = Future value  

P = Present value  

R = growth rate

N = number of years 2021 - 2014 = 7

130,000(1.026)^7 = 155,587.6

rounding off to the nearest whole  number is 155,588

To round off to the nearest whole number, look at the first number after the decimal, if it is less than 5, add zero to the units term, If it is equal or greater than 5, add 1 to the units term.

How do i Simplify 252 ÷ 3-3(4)(1)?
vivado [14]

9514 1404 393

Answer:

  72

Step-by-step explanation:

Enter the expression into your calculator.

__

If you're doing this by hand, follow the Order of Operations. The expression is the difference of a quotient and a product. The quotient is on the left, so it is figured first.

  252÷3 = 84

The product is figured next.

  3(4)(1) = 12(1) = 12

Then the difference is figured:

  84 -12 = 72

The simplified result is 72.
