Answer:
area of parallelogram =b×h
48cm²=b×6cm
48cm²/6cm=b
8cm=cm
Answer:
x=70
Step-by-step explanation:
angles of a triangle are always 180
180-40=140
140=2x
divide both sides by 2
70=x
Answer:
(-1, -8)
Step-by-step explanation:
So you would do the simplifying by "subtracting" the equations from each other. So to isolate the x, you could subtract the y away.
8x + y = -16
-3x + y = -5
-___________
11x = -11
x = -1
Then, substitute x into either equation.
8(-1) + y = -16
-8 + y = -16
Isolate y.
y = -8
For example #1 is 3/4 since there is no whole number but but for #3 1 and 1/8
