self-service car wash charges $4 for the initial 5 minutes plus an additional $0.75 for each minute after that. Nick only has $10 to spend on washing his car. Let m represent the number of minutes Nick spends washing his car. Create the inequality that symbolizes this situation.
Answers
Answer:
4+0.75(m-5) ≤ 10
Step-by-step explanation:
We start out with 4, since the car wash charges $4 for the first 5 minutes. We add to this the cost based on the minutes over 5 that he used the car wash.
Since m is the number of minutes, we first subtract 5 from this. This is because the first 5 minutes are included in the initial $4. Since each minute past 5 costs $0.75, we multiply m-5 by 0.75:
0.75(m-5)
Together this gives us
4+0.75(m-5)
He only has $10 to spend. This means he must spend less than or equal to $10; this gives us
4+0.75(m-5) ≤ 10

Hoping I'm looking at this correctly, but I'll do my best!
So we have a target with a diameter of 15 in., and a bull's-eye with a diameter of 3 in. We're basically looking for what 3 in. is to 15 in. in terms of size. So here we go:
First we're going to need to know the area of a circle, which is: Area = πr².
We're going to take the area of both the whole target, and then just the bullseye.
Area of Whole Target: π(15/2)² ⇒ π(7.5)² = 176.71 in³.
Area of Bullseye: π(3/2)² ⇒ π(1.5)² = 7.07 in³.
So far so good? (It's late around here so I'm sorry if I'm missing steps!)
Now from here, all we have to do is divide the area of the bullseye by the area of the target to find our answer.
⇒ 7.07 / 176.71 = .04
In other terms, the bullseye takes up around 4% of the target.
-Hope this helps and please correct me if this turns out to be incorrect!

Hey there! :)
Answer:
x ≤ 3
Step-by-step explanation:
Given:
4x + 6 ≤ 18
Subtract 6 from both sides:
4x ≤ 12
Divide both sides by 4:
4x/4 ≤ 12/4
x ≤ 3
Step-by-step explanation:
4x+6 <_ 18
-6 -6
4x <_ 12
Divide 4 both sides by 4
Therefore, x is less than or equal to 3

The required formula width of the rectangle in terms of w is .
Given ,
The perimeter of a rectangle = p
Formula = P = 2l + 2w,
Where, l is the length of the rectangle and w is the width of the rectangle.
We have to find
The formula in terms of w width.
According to the question,
The formula of a rectangle is P (perimeter) = 2W (the two widths added together) + 2L (the two lengths added together).
Now ,
Let "x" is often used, and solve for x. You could keep W instead of X also.
P= 2x + 2L
isolate the 2x by subtracting2L from both sides.
P - 2L= 2x
Now isolate the x by dividing both sides by 2 and ,
Where, x = w,
Hence, The required formula width of the rectangle in terms of w is
