Answer:
The answer is : -15 (C)
Step-by-step explanation:
–19 = x – 4
x - 4 = -19
x = -19 + 4
x = -15
Answer:
2a+15 = 125(being alternate angle)
or,2a = 125-15
or,2a = 110
or,a = 110÷2
,a = 55
again,2a+15+b+30=180(Being co-interior angle)
or,2×55+15+b+30=180
or,110+15+30+b=180
or,155+b=180
or,b=180-155
Therfore,b=25
Distributive property
Use multiplication to simplify
Simplify using addition
Add both sides by 9 to simplify
Multiply each side by -3/4 and simplify
Answer:
Step-by-step explanation:
Represent the number by x. Then:
9x - 4 = 23
Answer:
5.2 metres
Step-by-step explanation:
v = pi. r^2 . h
4.1 = 3.1416 × 0.25 * h
h = 5.22 m
