1/3 = 4/12
1/4 = 3/12
7/12 they ate
12-7=5
5/12 is left
Answer: 100?
Step-by-step explanation: not 100 percent sure tho, just what makes the most sense
Answer:
D) x=-3, y=-7
Step-by-step explanation:
9x - 7y = 22
x + 3y= -24
9x - 7y = 22
x= -24-3y
9(-24-3y)-7y=22
x= -24-3y
-216-27y-7y=22
x= -24-3y
-34y=22+216
x= -24-3y
-34y=238
x= -24-3y
y=238/(-34)
x=-24-3y
y=-7
x=-24-3*(-7)
y=-7
x=-24+21
y=-7
x=-3
(x,y)=(-3,-7)
3y = x - 1...I am going to re-arrange this.....-x + 3y = -1
-x + 3y = -1
x - 2y = 2
---------------add...u will notice that the x's cancel
y = 1
3y = x - 1
3(1) = x - 1
3 = x - 1
3 + 1 = x
4 = x
solution is (4,1)
If the scale factor is 1 1/2, then we can multiply x's corresponding side by 1 1/2 to get x.
The corresponding side is 2, so 2 * 1 1/2 is 3, making x = 3.
