Answer:
87
Step-by-step explanation:
Do what's inside the paranethesis first
2+(9*3)=2+27=29
29*3=87
Answer:
x = -3h
x = -12
Step-by-step explanation:
Given equation is 
To find the value of x in terms of h we will solve the expression to isolate x on one side of the equation.
by subtracting 1 from both the sides of the equation,


Multiplying 'h' on both the sides of the equation,

x = -3h
If h = 4,
x = (-3)(4)
x = -12
Move the decimal places of both numbers to the right by one, then divide normally.
Answer:
30
Step-by-step explanation:
Prime factorization of the numbers:
2 = 2 × 1
6 = 2 × 3
15 = 3 × 5
LCM(2, 6, 15)
= 2 × 3 × 5
= 30
Answer:
this is correct
Step-by-step explanation:
f continous in x=30 means that it should be the same value for 1.25 x 30 and 1.10 x 30 + k so k =4.5
