A the slope of the line is 1
to calculate the slope m , use the ' gradient formula '
m = ( y₂ - y₁ ) /( x₂ - x₁ )
where (x₁, y₁ ) = 6, 3) and (x₂, y₂ ) = (9, 6)
m = 
= 
= 1
The perimeter of the rectangle is 2(2x+5), and the perimeter of the triangle is x+7+x+4+x+11, which simplifies to 3x+22.
Therefore...
3x+22=4x+10
x=12
The perimeter of the rectangle is 2(2(12)+5)=2(24+5)=2(29)=48.
a. x=12
b. The perimeter of each figure is 48.
Answer:
130
Step-by-step explanation:
Angle B = 180 - Angle A
180 - 50 = 130
Answer:
A. 6.75
Step-by-step explanation:
8x+18=4x+57
8x-4x=57-18
4x=39
4x+57=180-(8y+30)
39+57=180-8y-30
96=150-8y
8y=150-96
= 54
y= 54/8 = 6.75
Do you mean the 2/3, 4/5,2/8 etc.are fractions? Or dividing each number? If so for dividing each number the answer is 0.9. For fractions the answer is 7 and 1/2. Hope I helped!
