Answer:
16 books
Step-by-step explanation:
133-5=128
128/8=16
The difference between them is 10
-4 - 6 = -10, however since it is only asking for the <em>difference, </em>your answer would be 10.
Replace X with 3 and simplify. The answer you would get is 11.
Answer:
90°
Step-by-step explanation:
as a straight line is 180°
and the angle 4 is 90 degrees it must mean that the other side is 90 degrees too
Answer:
x=2y-8
We use the substitution of x in the second equation
2*(2y-8)+3y= -2
4y-16+3y=-2
7y-16= -2
7y= -2 +16
7y=14
y=14Ș7
y=2
so x= 2*2 -8
x=4-8
x=-4
the solution is (x,y)=(-4, 2)
