use the substitution method to solve the sstem of equations choose the correct ordered pair 2x-y=10 and 2x-2y=4

(8, 6)

Step-by-step explanation:

2x - y = 10

2x - 2y = 4

=>

x - y = 2

x = y + 2

we put that into the first equation

2×(y+2) - y = 10

2y + 4 - y = 10

y + 4 = 10

y = 6

=>

x = y + 2 = 6 + 2 = 8

so, we have a ordered pair (x, y) = (8, 6)

452,489 to the nearest thousand is 452,000

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
