18 = 0.45 * n
the missing number is 40
Answer:
see below
Step-by-step explanation:
Let r = number of rides
total amount of money spent has to be less than or equal to 50
costs are admission and food and rides
rides cost 1.50 each
50≥ admission + food + rides
50 ≥ 15 +10 + 1.50r
Combine like terms
50 ≥25 + 1.50 r
Subtract 25 from each side
50-25 ≥25-25 + 1.50 r
25 ≥ 1.50 r
Divide by 1.5 on each side
25/1.5 ≥ 1.5r/1.5
50/3 ≥ r
Changing this to a mixed number
16 2/3 ≥r
We can only take a whole number of rides
r = 16
Beverly has not spent all of her 50 dollars since there was a fraction for the rides
cost = 15 +10 + 1.50r
15+10 + 1.5*16
25+24
49
She has 1 dollar left
Answer: g=4
Step-by-step explanation:
7x + 5(x + 3) + 4x + x + 2 =
= 7x + 5x + 15 + 4x + x + 2 = 17x + 17
Answer
Step 1: Add -x^2 to both sides.
x2+c+8x+−x2=0+−x2
c+8x=−x2
Step 2: Add -8x to both sides.
c+8x+−8x=−x2+−8x
c=−x2−8x
Answer:
c=−x2−8x
