Answer:
$24
Step-by-step explanation:
Let the total amount of her allowance = a
We are told that she spent $8 on belt
And the total amount she spent = $22
The Fraction of allowance spent on
Shirt = 1/4
Skirt = 1/3
Hence, the equation is given as:
1/4 × a + 1/3 × a + $8 = $22
Collect like terms
a/4 + a/3 = $22 - $8
a/4 + a/3 = $14
The Lowest Common Denominator = 12
3a + 4a/12 = $14
7a/12 = $14
Cross Multiply
7a = $14 × 12
7a = $168
a = $168/7
a = $24
Therefore, her total allowance = $24

Solve 5(y - 10) = -5
Answer:
y = 9
Step-by-step explanation:
Trying to get the variable alone is the main goal in solving these
to get the variable alone here we can divide both sides by 5, which gets us
y - 10 = -1
now we can add 10 to both sides to get y = 9

Pleaseeeeee help this is due today and I don’t know how to do thissss! Tug of War Activity
DIRECTIONS: Use the information provided about the first two rounds to figure out who will win the remaining rounds of the Tug of War.
Round 1:
On one side of the rope, there are four acrobats who all have equal strength. On the other side are five grandmas who each have equal strength as well. The result of the tug of war is dead even-- it’s a perfect tie.
Round 2:
On one side is Ivan the dog. On the other side are two grandmas and one acrobat. Again, it is dead even-- a perfect tie.
Round 3:
Three grandmas and Ivan are pulling against four acrobats. Which team wins? Justify your answer with at least 2 sentences.
Round 4:
Ivan and three acrobats are matched up against a team of grandmas. The result is a tie-- the two sides are evenly matched. How many grandmas were on the team? Explain your reasoning.
Bonus Round 5:
Create two teams of your choice in Round 5 that are not equally matched. Use Ivan and at least one acrobat and one grandma on either team. Explain which side will win and how you know.

Step-by-step explanation:
A florist is looking to make arrangements of red and white roses for bouquets. The flowers are priced so that she makes a profit of $1.25 per red rose and $1.00 per white rose in a bouquet. Her goal is to make at least $1000 from sales of these bouquets. Based on her available time and supplies of red and white roses, she is considering two possibilities: 130 bouquets of 4 red roses and 3 white roses each or 110 bouquets of 3 red roses and 5 white roses each. Will either of these possibilities turn the profit the florist is seeking?
Answer:
Option 1Step-by-step explanation:
Option 1
130 bouquets of 4 red roses and 3 white roses each. Profit is:
130*(4*$1.25 + 3*$1) = $1040 > $1000Option 2
110 bouquets of 3 red roses and 5 white roses each. Profit is:
110*(3*$1.25 + 5*$1) = $962.50 < $1000As we see option 1 is bringing target profit so should be her choice
Answer:
30 bouquets of 4 red roses and 3 white roses each.

the volume of a cylinder tank is 936 cubic meter .if its height is 6 m determine the base area of tank
Answer:
156 cm²
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = Ah ( A is the area of the base and h the height )
Here V = 936 and h = 6, then
936 = 6A ( divide both sides by 6 )
A = 156 cm²

Identify the value of a if
y= ax+ 7x + 2
and the point (2, 12) is on the graph.
Answer:
a=-2
So yep. ;)
Step-by-step explanation:
Alright, so, (2,12), 2 is the x and 12 is the y.
Stick them into the equation: [tex]12=a*2+(7*2)+2[/tex]
Then, solve:
[tex]12=a*2+14+2[/tex]
a = -2
So yes, they're on the graph.

Explain how you could use multiplication to help check your answer to Number 1
Answer:
1/10
Step-by-step explanation:
you can find the reciprocal of 2 (which is 1/2) and multiply it to 1/5 and get 1/10, that is your answer
I hope this answer helped, and if it was correct, please mark this as brainliest! Thank you!
Answer:
1/10
Step-by-step explanation:
You first divide and then divide just becomes multiplication(I know its weird)
K(Keep) C(Change) F(Flip)
(1/5 ) (division becomes) x (The whole number 2 becomes the recipicol 1/2)
Then you multiply 1/5 times 1/2 =1/10
A sandwich shop prepares 3 sandwiches in 126 seconds and 8 sandwiches in 336 seconds. At this rate, how many seconds will it take to prepare 5 sandwiches?
Answer: 210 seconds.
Time ÷ sandwiches
126 ÷ 3 = 42
336 ÷ 8 = 42
So it takes 42 seconds to make 1 sandwich.
42 seconds × 5 sandwiches = 210 seconds.

Two fractions are called equivalent if they have the same numeric value.
For example : 1/2 and 2/4 are equivalent, y/(y+1)2 and (y2+y)/(y+1)3 are equivalent as well.
To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.
L. Mult. • L. Num. 2x+5
—————————— = ——————————
L.C.M 3 • (2x+5)
R. Mult. • R. Num. (x+2) • 3
—————————— = ——————————
L.C.M 3 • (2x+5)
Add the two equivalent fractions which now have a common denominator . Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
2x + 5 - ((x + 2) • 3) -x - 1
——————————— = —————————
3 • (2x + 5) 3 • (2x + 5)
Pull out like factors :
-x - 1 = -1 • (x + 1)
-x - 1
—————————— = 0
3 • (2x + 5)
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now, to get rid of the denominator, multiply both sides of the equation by the denominator.
-x - 1
——————— • 3 • (2x + 5) = 0 • 3 • (2x + 5)
3 • (2x + 5)
Now, on the left hand side, the 3 • 2x + 5 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
-x - 1 = 0
Solving a Single Variable Equation:
Solve : -x - 1 = 0
Add 1 to both sides of the equation :
-x = 1
Multiply both sides of the equation by (-1) : x = -1
In a town election azeem got 42 percentage of the votes cast and hamza got the remaining votes.If the total number of votes cast is 40000. Find the votes obtained by Hamza .
Answer:
23200
Step-by-step explanation:
42 percent of 40000 is 16800
40000-16800=23200
please give me brainliest!!!<3
Answer:
23,200
Step-by-step explanation:
Total number of votes cast is 40,000
Since Azeem got 42% of the votes casted, then the votes obtained by him would be;
= 42% × 40,000
= 16,800
To get the number of votes obtained by Hamza, we will subtract the votes obtained by azeem from the total votes casted since there are only two candidates in that town, hence number of votes obtained by Hamza would be;
= 40,000 - 16,800
= 23,200.
Therefore, the number of votes obtained by Hamza is 23,200

Step-by-step explanation:
Substituting values of a and b in equation
3(-5)+2(-6)-3
-15-12-3
-15-15
-30
Answer: -30.
Step-by-step explanation:
We start by multiplying 3 by -5 and 2 by -6.
So the new equation will be [tex]-15-12-3[/tex].
Then, we can either minus -12 by -3 or we can minus -15 by -12. Either way, we get the right answer.
[tex]-15-12=-27[/tex]
Then, the new equation will be [tex]-27-3[/tex].
[tex]-27-3 = -30[/tex].
Answer: [tex]-30[/tex].
find the measure of
a. 71 degrees
b. 109 degrees
c. 180 degrees
d. 82 degrees
Answer:
71°
Step-by-step explanation:
Given;
<A=27°
<B=82°
<T=?
We add all angles and subtract it from 180 since an interior angle adds up to 180
<A+<B+<T=180
27°+82°+<T=180
109°+<T=180
<T=180-109
<T=71°
Therefore angle T <T is equal to 71°degrees
