The answer is 5 hours. Because if she works for $8 per hour and came home with $53, you subtract the 13 from the tips which leaves you with 40, and 40 divided by 8 is 5.
Answer:
should be left in the candy bar.
Step-by-step explanation:
Jenn and David shared a candy bar. Let's assume the bar was split into 10 parts, since 10 is the denominator of the fraction.
First, we need to add how much that the candy bar was eaten so we can subtract easier.
Jenn ate three tenths.
David ate four tenths.
So, seven tenths of the candy bar was eaten. We need to subtract that from a whole, because we need to know how much candy is left.
So, there are 3/10, or 0.3, of the candy bar left to share later.
Answer:
D. (0,-4)
Step-by-step explanation:
When you plug in 0 into the x and -4 into the y variable you get 2(0)-4(-4)>15.
Then you solve and get 0+16>15.
then you at and get 16>15.
16 is greater than 15 which makes D correct
Answer:
Percentage increases and decreases, are found by setting the problem up proportionally.
You are trying to find what percentage of 17.37 is 8.30 first.
so What %/100 = 8.30/17.37
Now define a variable:
Let x = What%
x/100 = 8.30/17.37
17.37x = 830
x = 830/17.37
x ≈ 47.78
8.30 is approximately 47.78% of 17.37, so the percentage decrease is 100% - 47.78% = 52.22%
The percentage decrease is approximately 52.22%
Let x= number of days
1.5x+6=45
subtract 6 from both sides
1.5x=39
divide both sides by 1.5 to get
x=26
it will take 26 days for the plant to reach 45 inches in height
