What is the solution to the system of equations? 3x + 10y = -47 5x- 7y = 40<br>Please and thank u
anastassius [24]

Answer:

x=1, y=-5

Step-by-step explanation:

Given equations are:

3x+10y=-47\ Eqn\ 1\\and\\5x-7y=40\ Eqn\ 2

In order to solve the equation

Multiplying Eqn 1 by 5 and eqn 2 by 3 and subtracting them

So,

Eqn 1 becomes

15x+50y=-235

Eqn 2 becomes

15x-21y=120

Subtracting 2 from a

15x+50y - (15x-21y) = -235-120

15x+50y-15x + 21y = -355

71y = -355

y = -355/71

y =-5

Putting y= -5 in eqn 1

3x+10(-5) = -47

3x -50 = -47

3x = -47+50

3x = 3

x = 3/3

x = 1

Hence the solution is:

x=1, y=-5

Deffense [45]

Answer:

c + 11 = 20....subtract 11 from both sides

c = 20 - 11

c = 9

c + 11 = 20

9 + 11 = 20

20 = 20 (correct)

What is the sales tax on a jacket priced at $725 if the sales tax rate is 7%
Fiesta28 [93]
<span>Sales tax on a jacket with the price of 725 dollars.
the sales tax rate is 7%
=> Convert 7% into decimals
=> 7% / 100 = 0.07
Now, multiply the 0.07 in 725 dollars
=> 50.75
thus the total tax rate of the jacket price is 50.75
Now, let us calculate the total amount that you will be paying
=> 725 + 50.75
=> 775.75 = the total amount to be paid.</span>
