Answer:
10.5cm
Step-by-step explanation:
3+8+7=18, this means that there are 18 parts assuming each part reprecents 1cm
63/18=3.5
so 1 part=3.5cm
3.5*3=10.5cm
Answer:
8.3 - 0.6x = 11.3
Step-by-step explanation:
When you solve all of the equations, the x value for all is 5. On the last equation, x = -5

Answer:
The dimensions of the original rectangle are Length =12cm, Width=8cm
Step-by-step explanation
Let the length of the rectangle be x
Let the width of the rectangle be y
The perimeter of a rectangle is 40cm.
2(x+y)=40
Divide both sides by 2
x+y=20
If the length were doubled(2x) and the width halved(y/2), the perimeter would be increased by 16cm,i.e.(40+16)cm
Therefore:
Divide both sides by 2
From the first equation, x=20-y.
Substitute x=20-y into
Answer:
The answer is -13 = x
Step-by-step explanation:
Add 12 on both sides. Which cancels the -12 on the right.
-25+12=-13.
