Answer:

2x-6y=-24

2x=-24+6y

x=-24+6y÷2

x=-12+3y equation 1

x+(-5y)=-22

-12+3y-5y=-22

-13-2y=-22

-2y=-22+13

-2y=-9

y=-9÷2

y=4.5equation 2

putting value of equation 2 in equation 1

x=-12+3y

x=-12+3×4.5

x=-12+13.5

x=1.5 answer!!!

TiliK225 [7]

Answer:

a = 17, b = 6

Step-by-step explanation:

Sides GF and GH are congruent, so we have ...

GF = GH

30 = 2a -4 . . . . substitute given values

15 = a -2 . . . . . divide by 2

17 = a . . . . . . . . add 2

Sides FJ and HJ are congruent, so we have ...

FJ = HJ

3b +6 = 24 . . . . substitute given values

b +2 = 8 . . . . . . divide by 3

b = 6 . . . . . . . . . subtract 2

The values of a and b are (a, b) = (17, 6).

So far this month John calculated that he will earn $40 in comission for his $500 in product sales. If John would like his comis

Helen [10]

John made $40 commissions for $500 sales or 40/500. He wants $320 for an unknown amount of sales or 320/x.

40/500=320/x Cross multiply.

40x=160,000

Divide both sides by 40.

X=4,000

He needs his sales to be $4,000 to get $320 in commission.

Andre45 [30]

Step-by-step explanation:

8-12x=-6(34x-2)+4

8-12x=204x-12+4

subtract 8 from both sides.

-12x=204x-20+4

-12 turned to -20 because we subtracted 8.

add 20+4

-12x=204x-24

subtract 204x from both sides

-216x=-24

divide by -216x

So I would say it has infinitely many solutions
