the first step is multiplication
the second step is collect like terms
third step is division
1+tan^2(A) = sec^2(A) [Pythagorean Identities]
tan^2(A)cot(A) = tan(A)[tan(A)cot(A)] = tan(A)[1] = tan(A)

Answer:
18
Step-by-step explanation:
Sum of x, y and z = 20 × 3
= 60
x-5+y+4+z-5 = 60-5+4-5
= 54
Mean of x-5, y+4 and z-5
= 54 ÷ 3
= 18
It’s 8/15 decimal form it’ll be 0.53 hope this helped !
We want to know how many 1/8's are in 3/4, so we divide.

Flip the 2nd fraction and multiply:

Multiply the numerators and denominators together:

Divide:
