Answer:
The answer is A (Look at the graph of the relationship. Find the y-value of the point that corresponds to x = 1. That value is the unit rate)
Step-by-step explanation:
Because the proportional relation is defined by k = 
. If ratio is 
then it is a rate. Unit rate means per 1 unit such as 
or 
thus the correct answer is A.
First we need to know both the formula of A and B.
The formula of A is
C = 5 + 0.25p
with C representing total cost and p representing the amount of checks.
The formula of B is
C = 6 + 0.15p
with C representing total cost and p representing the amount of checks.
To find the point where A and B cost the same, we solve the following equation:
5 + 0.25p = 6 + 0.15p
Collecting terms gives us
-1 = -0.1p
Now we have to divide by -0.1 and we get.
10 = p
p = 10
So our answer: after 10 checks both accounts cost the same amount of money. Answer A.
2000 + 1500g ≤ 15000
1500g ≤ 15000 - 2000
1500g ≤ 13000
g ≤ 13000/1500
g ≤ 8 2/3
Therefore, the crane can safely lift a maximum of 8 2/3 cubic meters of gravel.
Answer:
<h2>S=$3</h2>
Step-by-step explanation:
Given that the cost of cooler is $44
money given to the two sons $50
let S represent the amount the two son will have to share equally
the change is 50-44=6
=$6
Then s=6/2=$3
applying with the expression directly we have
S = (50 - 44)/2
S = (6)/2
S=$3
