Answer:
128
Step-by-step explanation:
The two angles form a straight line so they add to 180
2m+62 + 3m +143 = 180
Combine like terms
5m+205=180
Subtract 205 from each side
5m+205-205=180-205
5m = -25
Divide by 5
5m/5 = -25/5
m = -5
We want to find the angle so we substitute the value of m into the the formula for the angle.
< RBM =3m +143 = 3(-5) +143 = -15+143 =128
Answer:
X= Gracie
X+7.2=Hilda
X+7.2-11.4=Janell
(X+X+X+7.2+7.2-11.4)÷3=62.6
(3x+3)÷3=62.6
3X+3=187.8 (I arrive at 187.8 because I multiple 62.6 by 3)
3X=187.8-3
3X=184.8
3X/3=184.8/3
X=61.6
Step-by-step explanation:
GRACIE X=61.6
Hilda X+7.2=61.6+7.2=68.8
Janell X+7.2-11.4=61.6+7.2-11.4= 57.4
Answer:
Step-by-step explanation:
A = (2)(3.14)(2)(4) + (2)(3.14)(2^2)
A = 75.36 in
Cross multiply your fractions. if you have x/3=5/7, x*7 has to equal 3*5, meaning 7x=15. divide both sides by seven to get x=7/15.
