m = 8

Let's solve your equation step-by-step.

−88=−3(4m+5)−(1−3m)

Step 1: Simplify both sides of the equation.

−88=−3(4m+5)−(1−3m)

−88=−3(4m+5)+−1(1−3m)(Distribute the Negative Sign)

−88=−3(4m+5)+(−1)(1)+−1(−3m)

−88=−3(4m+5)+−1+3m

−88=(−3)(4m)+(−3)(5)+−1+3m(Distribute)

−88=−12m+−15+−1+3m

−88=(−12m+3m)+(−15+−1)(Combine Like Terms)

−88=−9m+−16

−88=−9m−16

Step 2: Flip the equation.

−9m−16=−88

Step 3: Add 16 to both sides.

−9m−16+16=−88+16

−9m=−72

Step 4: Divide both sides by -9.

−9m/−9 = −72/−9

step-by-step explanation:

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
