Answer:
the answer is 1 and 3/4
Step-by-step explanation:
Answer:
x ≤ 22
Step-by-step explanation:
≤ means less than or equal to
≥ means greater than or equal to
This is the commutative property (of addition, but this applies to multiplication as well)It doesn't matter which order the numbers are added in, the same result will be achieved.1+2 = 2+12*4 = 4*2
The cost to equip all the stations in the chemistry lab is calculated as: $393.75.
<h3>How to Calculate Total Cost?</h3>
In this scenario, we are given the following:
Total number of stations = 21 stations
Length of rubber tubing each of the stations in the chemistry lab needs = 5 feet
Total length of rubber tubing needed for all stations in the chemistry lab = 21 × 5 = 105 feet
Cost of 1 rubber tubing = $6.25 per yard
Convert 5 feet to yard:
1 yard = 3 feet
x yard = 5 feet
x = (5 × 1)/3
x = 5/3 feet.
So, the cost of 1 rubber tubing = $6.25 per 5/3
Cost of total length of tubbing needed = (105 × 6.25)/5/3 = (105 × 6.25) × 3/5
Cost of total length of tubbing needed = $393.75
Therefore, the cost to equip all the stations in the chemistry lab is calculated as: $393.75.

Hello from MrBillDoesMath!
Answer:
0.5 x^4 + 12.5
Discussion:
Only the constant terms are "like" and can be combined. Nothing combines with x^4.
0.5 ( x^4 - 9) + 17 =
0.5 x^4 - 0.5 (9) + 17 = as 0.5(9) = 4.5
0.5x^4 - 4.5 + 17 =
0.5 x^4 + 12.5
Thank you,
MrB
