<span>y=3x-12
2x-3y=-13
substitute </span>y=3x-12 into <span>2x-3y=-13
</span><span>2x-3y=-13
</span>2x-3(3x-12)=-13
2x - 9x + 36 = -13
-7x = -49
x = 7
y=3x-12 = y=3(7) -12 = 21 - 12 = 9
answer
solution
x = 7 and y = 9
Answer:
you are right it is 9
Step-by-step explanation:
5 x 3 = 15 so you go 3 x 3 which = 9 :)
Answer:
X=7-3y
is the equation formed here
Answer:
$22,000
Step-by-step explanation:
So, we would multiply 20,700 and 7%. That equals to 1,449
Then we would multiply 1,449 and 15 that equals 21,735.
SO after 15 years it will be worth 21,735
But then we would round it up, because it is above 500.
So the total value rounded up will be $22,000
Hope this helps!
D, this is because you times the 3 red cars by 4 to get to 12 red cars so you times the 4 blue cars by 4 to get 16 blue cars.
