The first step is 10 - 7 + (2)(14)/4 which equals (2-step) = 3 + 28/4 (3-step) = 3 + 7 (finale-step) = 10
Answer: a=−3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
a−2+3=−2
a+−2+3=−2
(a)+(−2+3)=−2(Combine Like Terms)
a+1=−2
a+1=−2
Step 2: Subtract 1 from both sides.
a+1−1=−2−1
a=−3
Answer:
The third number is 40.
Step-by-step explanation:
If angle A and B are complementary that means,
Measure of angle A + Measure of angle B = 90°
(x+16)° + (x-12)° = 90°
x+16+x-12 = 90°
2x+4 = 90°
2x+4-4 = 90°-4 (Subtraction Property)
2x = 86°
2x/2 = 86/2 (Division Property)
x = 43°
So,
For the measure of angle A, Plug in the value of x
(x+16)° = 43+16 = 59° ( ANSWER)
