Answer:
$0 < p ≤ $25
Step-by-step explanation:
We know that coach Rivas can spend up to $750 on 30 swimsuits.
This means that the maximum cost that the coach can afford to pay is $750, then if the cost for the 30 swimsuits is C, we have the inequality:
C ≤ $750
Now, if each swimsuit costs p, then 30 of them costs 30 times p, then the cost of the swimsuits is:
C = 30*p
Then we have the inequality:
30*p ≤ $750.
To find the possible values of p, we just need to isolate p in one side of the inequality.
So we can divide both sides by 30 to get:
(30*p)/30 ≤ $750/30
p ≤ $25
And we also should add the restriction:
$0 < p ≤ $25
Because a swimsuit can not cost 0 dollars or less than that.
Then the inequality that represents the possible values of p is:
$0 < p ≤ $25
Answer:
4
Step-by-step explanation:
the correct answer is number 4
if X = 2 ==> 2x -5 = 2(2) -5 = 4 - 5 = -1
Hi!
[1] -3x-7y=8
[2] 3x-2y=-44
lets take [1]
-3x-7y=8
-7y=8+3x
-7y-8=3x
3x=-7y-8
No use 3x=-7y-8 and put it in 3x-2y=-44
-7y-8-2y=-44
-9y-8=-44
-9y=-36
9y=36
y=4
then use y in 3x-2y=-44
3x-2(4)=-44
3x-8=-44
3x=-36
x=-12
Therefore, y = 4 and x = -12
Answer:
C. 32%
Step-by-step explanation:
First, you have to determine the amount they spent on entertainment and food:
Salary $2,700
Taxes: 10%: $270
Fixed expenses: $1,161
Savings: $405
$2,700-$270-$1,161-$405= $864
Alycia spent $864 on entertainment and food. Now, you have to find the percent of her income that this amount represents:
($864/$2,700)*100= 32%
According to this, the answer is that the percent of her income that was spent on entertainment and food is 32%.
