Answer:
b = 10.5
Step-by-step explanation:
2(b-9) = 3
then:
2*b + 2*-9 = 3
2b - 18 = 3
2b = 3 + 18
2b = 21
b = 21/2
b = 10.5
check:
2(10.5 - 9) = 3
2*1.5 = 3

You can find the answer by dividing 63.4 by 0.58. This gives you 109.31. You can check the answer by multiplying the answer by 0.58, which gives you 63.4.
The answer is 109.31
Answer:
m<4 = 44°
Step-by-step explanation:
m<8 = 34°
m<9 = 40°
m<3 = 62°
m<2 = 34° + 40° (exterior angle theorem of a triangle)
m<2 = 74°
m<3 + m<4 + m<2 = 180° (sum of ∆)
62° + m<4 + 74° = 180° (substitution)
m<4 + 136° = 180°
m<4 = 180 - 136 (substitution property of equality)
m<4 = 44°
Answer:
x = 32
Step-by-step explanation:
x/4 +2 = 10
Subtract 2 from each side
x/4 +2-2 = 10-2
x/4 =8
Multiply each side by 4
x/4 *4 = 8*4
x = 32
