&4 - $2= $2 You have to round the numbers to the closest one right.
Answer:
Company B is the better deal. Diego will save $31.5.
Step-by-step explanation:
First, find the area of the rectangle: 45*30=1350 sq.ft.
Next, find out how much it will cost for Company A: $3.9 for 2 x 5 ft (10 sq.ft)
Divide 1350 by 10 to see how many of their sod rolls will fit into his yard=135.
Multiply $3.9 by 135=526.5$
Do the same with Company B: $150 for 450 sq.ft plus $45 delivery.
Dived 1350 by 450 to see how many rolls= 3
Multiply $150 by 3= $450, then add $45= $495
Subtract Company B's $495 from Company A's $526.5= $31.5 <-how much Diego saved.
Answer:
6/x^2
Step-by-step explanation:
Simplify the following:
2/x^2 + 4/x^2
2/x^2 + 4/x^2 = (2 + 4)/x^2:
(2 + 4)/x^2
2 + 4 = 6:
Answer: 6/x^2
Answer:
holy this is just substitution child
Step-by-step explanation:
1. y + 2, y = 4
if y is equal to 4, we can replace y in the equation
4 + 2 = 6
2. 6a / 3, a = 3
6 * 3 / 3 = 6
4. x - 7, x = 12
12 - 7 = 5
5. 2c - 4, c = 5
2 * 5 - 4 = 6
7. 2z - 3x
2 (8) - 3(5) =
16 - 15 = 1
8. 6x / (y + z)
(6 * 5) / (2 + 8)
30 / 10 = 3
