Answer:

x = -2 y = -4

Step-by-step explanation:

3x- 2y = 2 -> 15x - 10y = 10

5x - 5y = 10 -> 15x - 15y = 30

Substract one equation from another:

15x - 15x - 10y + 15y = 10 -30

5y = -20

y = -4

Plug in y into an equation

3x + 8 = 2

3x = - 6

x = - 2

A package is 15.5 inches long, 8.25 inches wide, and 5.5 inches high. What is the volume of the box? Enter your answer, rounded
Dmitriy789 [7]

Answer: 703.3125 in cubed

Step-by-step explanation:

The formula to find the volume of something is to…

1. Find the area of the base! Remember, area is length x width. In this case we would have 15.5 x 8.25 = 127.875

2. Multiply the base area we just found by the height! In this case, we take 127.875 x 5.5 and this gives us 703.3125 as our final answer!

Mr. Drysdale earned 906.25 in interest in one year on money that he had deposited in
VikaD [51]

Answer: Mr Drysdale deposited 14,500

Step-by-step explanation:

Using the simple Interest formula

Simple Interest = Principal(Initial Money) * Interest Rate * Time Period

I = P*R*T

I = PRT

To get P which is the initial money he deposited, we divide both sides by RT

I/RT = PRT/RT

I/RT = P

Therefore the money deposited

P = I/RT

Interest (I)= 906.25

Interest Rate (R)= 6.25% = { converting percentage to decimal} (6.25/100)= 0.0625

Time Period (T) = 1 year

Principal (P)= ?

P= I/RT

P= 906.25/(0.0625 * 1)

P= 906.25/0.0625

P= 1450

The money he deposited in his local bank is 14,500

C

the square of the sum of 7 times x and 3 is expressed as

7x + 3 ← the sum of 7 times x and 3

(7x + 3)² ← the square of the sum of 7 times x and 3

4 times the difference of x and 1 is expressed as

x- 1 ← the difference of x and 1

4(x - 1) ← 4 times the difference of x and 1

putting it all together gives

(7x + 3 )² / 4(x - 1 ) → C
