Students make 58.5 ounces of liquid soap for a craft fair. They put the soap in 4.5 ounce bottles and sell each bottle for $5.50. How much do the students earn if they sell all the bottles of liquid soap?
Step-by-step explanation:
first you want to divide the ounces of liquid soap we have by the ounce bottles we have (58.5 / 4.5 = 13 )
so now we know we have 13 bottles of liquid soap
then you want to multiply the 13 bottles of soap by how much they sell each bottle for ( 13 x 5.50 = 71.50 )
the answer: the students would earn $71.50 if they sell all the bottles of liquid soap
hope that helps :)

the system ax-by=-16 and ax+2y=20 has one solution at the point (3,4). Find a and b. (a=4,b=7)
Answer:
Step-by-step explanation:
substitute (3,4) to equation: ax+2y=20
3a+8=20
a=4
Then, 4x-by=-16
substitute (3,4) to solve b,
4*3-b(4)=-16
b=7

Oceanside bike rental shop charges 16 dollars plus 9 dollars an hour for renting a bike.Sam paid 52 dollars to rent a bike.How many hours did he pay to have the bike checked out?
Answer:
4 Hours
Step-by-step explanation:
Since the equation is:
y = 9x + 16
You have to find x
This is the logical way:
52-16 = 36 because thats the starting fee
So 36 divided by 9 equals 4
You do that because 9 is the charge per hr
So he rented it for 4 hours.
Hope this helps:)

Answer:
16.5
Step-by-step explanation:
27.50/5 =5.5x3=16.5
solve equation for x -16= 3x + 11
Answer:
13.5
Step-by-step explanation:
Step 1:
x - 16 = 3x + 11 Equation
Step 2:
- 16 = 2x + 11 Subtract x on both sides
Step 3:
- 27 = 2x Subtract 11 on both sides
Step 4:
x = - 27 ÷ 2
Answer:
x = 13.5
Hope This Helps :)
Answer:
[tex]x = -\frac{27}{2}[/tex]
Step-by-step explanation:
Combine like terms: x - 3x = 16 + 11Simplify: -2x = 27Divide each side by -2 to cancel out the -2 next to x. It should now look like this: x = -27/2I hope this helps!
Point H is between G and I. If HG = 8x + 7, HI = 3x - 2, and GI = 38, what would be the length of GH ?
Answer:
let's see what to do...
Step-by-step explanation:
H is between G and I.
G I = G H + H I
38 = 8 x + 7 + 3x - 2
38 = 11 x + 5
subtract the sides of equation minus 5
38 - 5 = 11 x + 5 - 5
33 = 11 x
divided the sides of equation by 11
33 ÷ 11 = 11 x ÷ 11
3 = x
So the lenght of (G H) is :
8 x + 7 -----¢ 8 (3) + 7 = 24 + 7 = 31
And we're done.
Thanks for watching buddy good luck.

The graph represents a person’s heart rate in beats per minute during 30 minutes of exercise.
A graph titled Cardiac Exercise. The horizontal axis shows time (minutes), numbered 3 to 30, and the vertical axis shows Heart Rate (b p m) numbered 15 to 150. The line starts at 75 b p m in 0 minutes, to 135 b p m from 6 to 25 minutes, and ends at 105 b p m at 30 minutes.
Which statement best describes the relationship between heart rate and time during exercise?
The heart rate increases for 6 minutes, remains constant for 19 minutes, and then gradually increases for 5 minutes.
The heart rate decreases for 6 minutes, remains constant for 19 minutes, and then gradually increases for 5 minutes.
The heart rate increases for 6 minutes, remains constant for 19 minutes, and then gradually decreases for 5 minutes.
