Answer:
h = 12
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
0.75h + 3 = 12
Step 2: Solve for h
Subtract 3 on both sides: 0.75h = 9Divide 0.75 on both sides: h = 12Step 3: Check
Plug in h into the original equation to verify it's a solution.
Substitute in h: 0.75(12) + 3 = 12Multiply: 9 + 3 = 12Add: 12 = 12Here we see that 12 does indeed equal 12.
∴ h = 12 is a solution of the equation.
Answer:
h = 12
Step-by-step explanation:
Given
0.75h + 3 = 12 ( subtract 3 from both sides )
0.75h = 9 ( isolate h by dividing both sides by 0.75 )
h = 12
What is 2.31 of 5.02
Answer:
11.5962
Step-by-step explanation:
2.31 of 5.02
In mathematics, saying "of" is the same as multiplying the two values, hence the problem is;
2.31 * 5.02
= 11.5962
Manuel and Felicia are comparing how much
money they have
• Manuel has $250.
• He saves $150 per week,
• Felicia has $1,650.
• She spends $200 per week.
• Let x = the number of weeks
• Let y = the amount of money at the end
of the week.
Which system of equations represents this
situation?
Answer:
y = 250 + 150xy = 1650 - 200xStep-by-step explanation:
Equation for Manuel:
y = 250 + 150xEquation for Felicia:
y = 1650 - 200xSolving we get:
250 + 150x = 1650 - 200x150x + 200x = 1650 - 250350x = 1400x = 1400/350x = 4 weeksand
y = 250 + 150*4 = 250 + 600 = $850After 4 weeks Manuel and Felicia will have equal amount of money- $850

A person jogs 4 kilometers in 32 minutes, the 2 kilometers in 22 minutes, and finally 1 kilometer in 16 minutes. What is the jogger's average speed in kilometers per minute?
Answer:
0.1km per minStep-by-step explanation:
what is average speed:
"The average speed of an object is defined as the distance traveled divided by the time elapsed. Velocity is a vector quantity, and average velocity can be defined as the displacement divided by the time."
step one:
given data
Distances Time
4km 32min
2km 22min
1km 16min
the total distance covered is
4+2+1= 7km
the total time taken = 32+22+16=70min
the average speed= distance/time
average speed= 7/70= 0.1km per min

Shayla bought 24 cupcakes. Each cupcake cost $0.35, including tax. Of the cupcakes she bought, 2 3 2 3 were vanilla, 1 12 1 12 were chocolate, and the rest were strawberry. What was the total cost of only the vanilla cupcakes?
Answer:
[tex]Vanillas = \$5.6[/tex]
Step-by-step explanation:
Given
[tex]Cup\ Cakes = 24[/tex]
[tex]Cost = \$0.35[/tex] (each)
[tex]Vanilla = \frac{2}{3}[/tex]
[tex]Chocolate = \frac{1}{2}[/tex]
Required
Determine the cost of all vanilla cupcakes
First, we need to determine the number of vanilla cakes.
This is calculated by multiplying the fraction of Vanilla by number of cupcakes
So:
[tex]Vanilla = \frac{2}{3} * 24[/tex]
[tex]Vanilla = \frac{2 * 24}{3}[/tex]
[tex]Vanilla = \frac{48}{3}[/tex]
[tex]Vanilla = 16[/tex]
Since 1 cupcake costs $0.35.
16 would cost 16 * $0.35
So:
Vanillas: ;;;;; [tex]16 * \$0.35 = \$5.6[/tex]

Kenny had a total of 140 minutes to read, do homework, and play video games he spent x minutes reading, he spent 2(x+5) minutes doing homework, he spent 25 minutes playing video games how many minutes did Kenny spend reading
Answer:
He spent 52.5 minutes reading.
Step-by-step explanation:
The equation from the word problem is 2(x+5)+25=140. Distribute 2 to the parentheses and get 2x+10+25=140. Combine like terms to get 2x+35=140. Subtract 35 from both sides and get 2x=105. Divide both sides by 2 and your final answer is x=52.5
Mary-Ann has $28, which is 2 1 3 as much money as Lola has. How much money does Lola have? find the number
Answer:
Lola has $12
Step-by-step explanation:
To find how much money Lola has, we need to divide $28 by 2 1/3:
28 ÷ 2[tex]\frac{1}{3}[/tex] = [tex]\frac{28}{1}[/tex] × [tex]\frac{3}{7}[/tex] = [tex]\frac{12}{1}[/tex] = 12
Hope this helps! :)
Answer:
$12
Step-by-step explanation:
Lola has x.
Mary-Ann has 2 1/3 times what Lola has. Mary-Ann has $28
2 1/3 * x = 28
Change 2 1/3 into a fraction.
(7/3)x = 28
Multiply both sides by the reciprocal of 7/3 which is 3/7.
(3/7) * (7/3)x = (3/7) * 28
x = 12
Answer: Lola has $12.

Tiffany buys a basket of watermelons on sale for \$9$9dollar sign, 9 before tax. The sales tax is 9\%9%9, percent.
What is the total price Tiffany pays for the basket of watermelons?
\$\$ dollar sign, space
Answer:
Tiffany pays a total price of $9.81 for the basket of watermelons
Step-by-step explanation:
Percentages
To increase a certain amount by a given percentage, we can first calculate the increasing amount and then add it to the original amount.
If the price of the basket of watermelons was $9 before tax, and the sales tax is 9%, we first calculate the tax amount to pay:
$9 * 9 / 100 = $0.81
Now we add it to $9 to get the total price paid by Tiffany:
Total price = $9 + $0.81 = $9.81
Tiffany pays a total price of $9.81 for the basket of watermelons
Answer:
9.81 it was confirmed :)

It rained all day on Mother's Day and the temperature dropped fourteen and seven tenth degrees. The next day the rain stopped and the temperature rose ten and nine tenths degrees. If the temperature at the beginning of Mother's Day was sixty five and eight tenths degrees, what was the temperature at the end of the day after Mother's Day?
Answer: The temperature was 1 8/10º at the end of the day after Mother's Day
Step-by-step explanation:
5 8/10º-14 7/10º=-9 1/10º at the end of Mother’s Day
-9 1/10º+10 9/10º=1 8/10º at the end of the next day after Mother’s Day

2. Similar rectangles have widths of 10 cm and 15 cm respectively. If the smaller rectangle's length is 18, what is the larger rectangle's length?
Answer:
8
Step-by-step explanation:
10/15=0.66666666666
0.66666666666 times 12 = 8 or the missing length
So the answer is 8 :)
Rectangles P, Q, R, and S are scaled copies of one another. For each pair, decide if the scale factor from one to the other is greater than 1, equal to 1, or less than 1. Four rectangles, labeled P, Q, R and S. Each rectangle is a scaled copy of one another. Ranked in order from least to greatest, the area of the rectangles are as follows: the area of P is equal to S, which are less than the area of Q, which is less than the area of R. From P to Q from P to R from Q to S from Q to R from S to P from R to P from P to S
I attached a diagram that will aid the understanding of the question.
Firstly, I would love to review what a scale factor is before going into the question.
If you have two shapes that are similar, that is they have corresponding angles, then the scale factor of one to the other is simply the ratio of any two corresponding lengths in the two similar geometric figures.
Looking at these figures in the question, we see that R is an enlargement of the other rectangles while Q is an enlargement of P and S. With this information we can answer the questions:
1. From P to Q, the scale factor greater than one because Q is bigger than P.
2. From P to R, the scale factor is greater than one for the same reason.
3. From Q to S, the scale factor is less than one because S is smaller than Q.
4. From Q to R, the scale factor is greater than one because R is bigger than Q.
5. From S to P, the scale factor is equal to one because they are equal.
6. From R to P, the scale factor is less than one because p is smaller than R.
7. From P to S, the scale factor is equal to one because they are equal.

Simplify. 8(2x - 3) + 11x
Answer:
27x-24
Step-by-step explanation:
Using distributive property, we can simplify 8(2x-3) to 16x-24. That becomes 16x-24+11x.
Then, we can add 16x and 11x to get 27x.
The answer will be 27x-24.

Kedar earns a monthly salary of $2,200 plus a 3.75% commision on the amount of his sales at men's clothing store. What would he earn this month if he sold $4,500 in clothing?
Answer:
$2368.75
Step-by-step explanation:
Kedar earns a monthly salary of $2200 and a commission of 3.75%
He sold $4500 this month
The first step is to calculate his commission for this month
His commission can be calculated as follows
= 4500 × 3.75/100
= 4500 × 0.0375
= 168.75
Therefore yr amount earned this month can be calculated as follows
= 2200 + 168.75
= $2368.75
