Alberto has 12 Dimes and 21 Nickels in his pocket.
How many of each type of coin does he have?Dimes value = 0.10$
Nickels value = 0.05$
Let d = number of dimes = 0.10d
Let d+9 = number of nickels = 0.05(d + 9)
Value of the Dimes + Value of the Nickels = total value of the coins
Write the equation:
0.10d + 0.05(d + 9) = 2.25
Distribute:
0.10d + 0.05d + 0.45 = 2.25
0.15d + 0.45 = 2.25
Subtract 0.45 from each side:
0.15d = 1.80
Divide to find the number of dimes.
d = 12
The number of nickels is d +9 = 12 + 9 = 21
Alberto has $2.25 in dimes and nickels in his pocket. He has 12 Dimes and 21 Nickels in his pocket.

the length of a rectangle is 5 less than 2 times its width, if the perimeter is 86ft, what is the length and width of the rectangle. Write and solve the equation
Answer:
Width: 16
Length: 27
Step-by-step explanation:
Let x be the width of the rectangle.
The length would then be 2x - 5
The perimeter is:
2x - 5 + x + 2x - 5 + x =
6x - 10 = 86
Solve.
6x = 96
x = 16
Thus,
Width: 16
Length: 27

My little sister need help with this problem. Annabelle arranged her 42 building blocks into 3 rows of 14 blocks. Then, she rearranged them into 6 rows of 7 blocks. What two other factor pairs could Annabelle use to help her rearrange the blocks again?
Explain your answer using complete sentences.
Answer:
21 rows and two Blocks
1 row 42 Blocks
Step-by-step explanation:
Number of blocks with Annabelle = 42
First arrangement = 3 rows 14 blocks
Second arrangement = 6 rows 7 blocks
Solution
The other two factor pairs that could be used to rearrange the blocks again?
Solution:
Here, we will have to find the factor pairs of total number of blocks present with Annabelle.
i.e. 42
First of all, let us have a look at the factor pairs of 42.
Therefore, the other two factor pairs can be 2, 21 and 1, 42.
The other two possible factor pairs are:
21 rows 2 blocks
1 row 42 blocks

Answer:
$18.00
Step-by-step explanation:
To find the price of one cup divide 4.00 by 2
4.00/2=2.00
Now that we know the price of one cup of coffe we multiply that to find the price of nine cups of coffee
2.00x9=$18.00
Hope this helps
Answer:
It will cost $18
Explanation:
Marianne is buying 4 bundles of the two large coffees. That's $16 but she still needs to buy her 9th coffee. We can say that one coffee is $2.00 since it cost $4.00 for two coffees. So she'll need to buy one more coffee that will tally up the cost to $18.

Step-by-step explanation:
You rent an apartment that costs \$800$800 per month during the first year, but the rent is set to go up 9.5% per year. What would be the rent of the apartment during the 9th year of living in the apartment? Round to the nearest tenth (if necessary).\
Pls help I'm dying here
Answer:
Monthly rent for Year 9: $1,653.5
Total cost of rent for the whole 9th year: $19,841.9
Step-by-step explanation:
Given the monthly rent of $800 for an aparment, for which it is set to increase by 9.5% annually:
Increase in the Monthly Cost of RentYear 1:The monthly rent will stay at $800 for the first year.
Year 2:For year 2, we must add the 9.5% increase in the monthly rent. In order to determine the 9.5%, simply multiply the monthly rent by 0.095 (the decimal equivalent of 9.5%), then add the product to the monthly rent in year 1 of $800.
9.5% increase for Year 2: $800 × 0.095 = $76
Monthly rent in Year 2: $800 + $76 = $876
Year 3:For year 3, we must add the 9.5% increase in the monthly rent from Year 2 ($876).
9.5% increase for Year 3: $876 × 0.095 = $83.22
Monthly rent in Year 3: $876 + $83.22 = $959.22
Year 4:For year 4, we must add the 9.5% increase in the monthly rent from Year 3 ($959.22).
9.5% increase for Year 4: $959.22 × 0.095 = $91.13
Monthly rent in Year 4: $959.22 + $91.13 = $1,050.35
Year 5:For year 4, we must add the 9.5% increase in the monthly rent from Year 4 ($1,050.35).
9.5% increase for Year 5: $1,050.35 × 0.095 = $99.78
Monthly rent in Year 5: $1,050.35 + $99.78 = $1,150.13
Year 6:9.5% increase for Year 6: $1,150.13 × 0.095 = $109.26
Monthly rent in Year 6: $1,150.13 + $109.26 = $1,259.39
Year 7:9.5% increase for Year 7: $1,259.39 × 0.095 = $119.64
Monthly rent in Year 7: $1,259.39 + $119.64 = $1,379.03
Year 8:9.5% increase for Year 8: $1,379.03 × 0.095 = $131.00
Monthly rent in Year 8: $1,379.03 + $131.00 = $1,510.04
Year 9:9.5% increase for Year 9: $1,510.04 × 0.095 = $143.45
Monthly rent in Year 9: $1,510.04 + $143.45 = $1,653.50
Yearly Cost of Rent:In order to determine the yearly cost of renting an apartment, simply multiply monthly rent by 12. In other words:
Year 1: $800 × 12 = $9600
Year 2: $876 × 12 = $10,512
Year 3: $959.22 × 12 = $11,510.64
Year 4: $1,050.35 × 12 = $12,604.15
Year 5: $1,150.13 × 12 = $13,801.55
Year 6: $1,259.39 × 12 = $15,112.69
Year 7: $1,379.03 × 12 = $16,548.40
Year 8: $1,510.04 × 12 = $18,120.50
Year 9: $1,653.50 × 12 = $19,841.94
Therefore, due to the 9.5% annual increase in rent, the monthly cost of an apartment during the 9th year is $1,653.5, or $19,841.9 (12-months' worth of rent).
How do I solve
-3x+y=24
-2x=+18+5y
Answer:
Let's solve by eliminating x. Since 18 is the lowest common multiple , let's multiply the first equation by 3 and the second by -2.
18x−21y=24
−18x+10y=−2
Add the two equations.
−11y=22
Divide by -11 to isolate y.
y=−2
Substitute y=−2 into either of the 2 equations, I'll just use the second one.
9x+10=1
9x=−9
x=−1

3 t-shirts cost £25.95.
How much do 10 t-shirts cost?

Answer:
£86.50
Step-by-step explanation:
To find how much 10 t-shirts cost we have to find how much they cost individually.
3 T- Shirts / 25.95 = 8.65 which means that each T-Shirt Costs 8.65.
8.65 x 10 T-Shirts = £86.50
