Use elimination to solve each system if equation 3x+2y=0and x-5y=17
kotykmax [81]

Answer:

y = -3

x=2

Step-by-step explanation:

3x + 2y = 0

x - 5y=17

to use the elimination you have to make one of the numbers same

so

3(x-5y=17)

and you would have to change the sign so that both of the 3x could cancel out.

New system of equation

3x + 2y = 0

-3x+15y=-51

17y=-51

y = -3

so we know the y value so now you could find the x value take one equation

x - 5y=17

x +15=17

x = 2

you could try it with both of the equations

3x + 2y = 0

3x + - 6=0

3x-6=0

3x=6

x=6/3

x=2

If 10% is deducted from a bill, $58.50 remains to be paid. How much is the original bill?
NARA [144]

Answer:

From the above we can roughly for an equation which is:

58.50 = Bill - (10% x Bill)

58.5 = Bill - (1/10 x Bill)

58.5 = 9/10 x Bill (Divide both sides by 9/10)

We get:

Bill = 58.5 / (9/10)

Bill = 65

Original bill is $65.

I will give BRAINLIEST to whoever is correct.
NikAS [45]
The correct answer is the last number line because with an inequality, the "equal to" sign below the "<" or ">" means the circle should be filled in. The line is traveling in a negative direction because the inequality says that n is less than -1.
