300,000,000+4,000,000+800,000+400
Answer:
12
Step-by-step explanation:
Average of A and B is 6
(A+B) /2 = 6
Multiply each side by 2
A+B = 12
average of X, Y, and Z is 16
(X+Y+Z)/3 = 16
Multiply each side by 3
(X+Y+Z) = 48
To find the average of all of them
(A+B+X+Y+Z)/5
replace A+B with 12 and X+Y+Z with 48
(12+48)/5
60/5 = 12
X + 3 = 0
2x - 1 = 0
It would be D.
Answer:
It’s 20
Step-by-step explanation:
Write an equation where x = Justin's orders
93 = (x) + (2x) + (x + 5)
Simplify the equation:
93 = 4x + 5
Subtract 5 from both sides:
88 = 4x
Divide 4 on both sides:
22 = x
Solve for the orders:
x = 22 = Justin
22(2) = 44 = Chang
22 + 5 = 27 = Heather.
Hope this helps!
