Answer:
Step-by-step explanation:
Step 1: Subtract 15 from both sides.
1.5r+15−15=2.25−15
1.5r=−12.75
Step 2: Divide both sides by 1.5.
1.5r
1.5
=
−12.75
1.5
r=−8.5
Answer: r=-8.5
Step-by-step explanation:
1.5r+15=2.25
1.5r+15-15=2.25-15
1.5r=-12.75
1.5r/1.5=-12.75/1.5
r=-8.5

carries family broke a package of graham crackers into 32 pieces. carries two brothers each ate 1/8 of the pieces and the rest of the family ate 7/16 of the pieces.
carries two brothers each ate ____ pieces
the rest of carries family ate ____ pieces
there were ____ pieces remaining
Answer:
Carrie's two brothers each ate 4 pieces, and the rest of the family ate 14 pieces, there were 10 pieces left.
Step-by-step explanation:
First, change all of the fraction's denominators into 32:
1/8 = 4/32
7/16 = 14/32
This gives us the answer to the first two questions.
Then add up the amount of pieces each person ate. Carrie has two brothers, so we double 4/32, which gives us 8/32. 8/32 + 14/32 = 22/32.
32 - 22 = 10, so there are 10 pieces remaining.
Hope this helps!
Answer:
Carries two brothers ate 4 pieces.
The rest of Carries family ate 14 pieces.
There were 14 pieces remaining.
Step-by-step explanation:
To find out how much the brothers ate you can divide 32 by 8 to get 4. For the family you can turn 7/16 into 32nds
16 x 2 = 32 and 7 x 2 = 14
so the family ate 14 pieces. Add 14 + 4= 18 so that's how much they all ate in total then 32-18 = 14. That means 14 pieces are left.
Hope that helps and have a great day!

Which value is the LARGEST?
a. 0.65
b. 33%
3
C.
5
d. 0.75
Answer:
d. 0.75 (assuming that choice c. is 3/5)
Step-by-step explanation:
Is C. 3/5? I'm assuming it is.
Write all numbers as decimals to make it easier to compare them.
a. 0.65 = 0.65
b. 33% = 0.33
c. 3/5 = 0.6
d. 0.75 = 0.75
Now that all numbers are written as decimals, we see that the greatest of them is 0.75
Answer: d. 0.75 (assuming that choice c. is 3/5)
Step-by-step explanation:
It's C I mean number 5 because the other ones are below 1 and 5 is greater than 1

A parking attendant charges a different rate for cars than for trucks. It costs $10.75 to park 3 cars and 2 trucks. It costs $12.25 to park 7 cars and 1 truck. How much does it cost to park a single car? A single truck?
Answer:
$1.25 to park a car and $3.50 to park a truck
Step-by-step explanation:
Set up a system where c is the number of cars parked and t is the number of trucks:
3c + 2t = 10.75
7c + t = 12.25
Solve by elimination by multiplying the bottom equation by -2 to eliminate t:
3c + 2t = 10.75
-14c - 2t = -24.5
Add them together and solve for c:
-11c = -13.75
c = 1.25
Then, plug in 1.25 as c in the equation to solve for t:
3c + 2t = 10.75
3(1.25) + 2t = 10.75
3.75 + 2t = 10.75
2t = 7
t = 3.5
So, it costs $1.25 to park a car and it costs $3.50 to park a truck

Evaluate f(2) for the function f(x) = 3x2 + 2x - 5
Answer:
The answer for f(2) is 11.
Step-by-step explanation:
f(x) = 3x2 + 2x - 5
f(2) = 3(2)2 + 2(2) - 5
f(2) = 6(2) + 4 - 5
f(2) = 12 + 4 - 5
f(2) = 16 - 5
f(2) = 11
The value of f(2) is 11 and this can be determined by using the arithmetic operations and the given data.
Given :
[tex]\rm f(x) = 3x^2+2x-5[/tex]
The following steps can be used in order to determine the value of f(2):
Step 1 - Write the given function.
[tex]\rm f(x) = 3x^2+2x-5[/tex]
Step 2 - The arithmetic operations can be used in order to determine the value of f(2).
Step 3 - Now, substitute the value of (x = 2) in the given function.
[tex]\rm f(2) = 3(2)^2+2(2)-5[/tex]
Step 4 - Simplify the above expression.
[tex]\rm f(2) = 3\times 4+4-5[/tex]
f(2) = 12 - 1
f(2) = 11

A species of fish was added to a lake. The population size Pt of this species can be modeled by the following function, where t is the number of years from the time the species was added to the lake. P(t) = 1000+(12e^−0.34t)where t is the number of years from the time the species was added to the lake.
Find the initial population size of the species and the population size after 9 years. Round your answers to the nearest whole number as necessary.
Answer:
1,012 ; 1,001
Step-by-step explanation:
Given the population function :
P(t) = 1000+(12e^−0.34t)
where t is the number of years from the time the species was added to the lake.
Initial population size of the species ; that is the population at year 0
At time, t = 0
P(0) = 1000+(12e^−0.34(0))
= 1000 + (12e^0)
= 1000 + 12(1)
= 1012
Initial population = 1,012
Population after 9 years :
P(9) = 1000+(12e^−0.34(9))
= 1000 + (12e^-3. 06)
= 1000 + (12×0.0468876)
= 1000 + ( 0.5626523)
= 1000.5626
= 1001 ( nearest whole number)

Jordan uses three lemons to make 1 pitcher of lemonade. He makes 4 pitchers. How many lemons does he use altogether? *What visual would you use to draw this story problem?
Answer:
The number of lemons Jordan uses to make the 4 pitcher of lemonade is 12 lemons
Step-by-step explanation:
The number of lemons the Jordan uses to make 1 pitcher of lemonade = three lemons
The number of pitcher lemonades Jordan makes = 4 pitcher of lemonades
The number of lemons Jordan uses altogether, is given by the following relation;
1 pitcher of lemonade = 3 lemons
4 pitcher of lemonades = 4 × 3 lemons = 12 lemons
Therefore, the number of lemons Jordan uses to make the 4 pitcher of lemonade is 12 lemons.
