Answer:
84
Step-by-step explanation:
Because 3 people are making 21 shirts
If there were 12 people then your timesing the answer by 4 so 21=3 people so whats 3 people x 4=12 so then times the shirts by 4
Whats 21 x 4=84 so there is your answer.
Hope it helps have a great day:)
The solution is, 84 long will it take 12 people.

Please answer please and what do you do to solve this?
9+4(a+5)
a) 18+4a B)29+4a
C) 33+4a D) 23+4a
Answer:
B) 29 +4a
Step-by-step explanation:
for this question we need to expand the brackets. to do this you would times everything in the brackets separately by 4, 4 times a which is 4a and 4 times 5 which is 20.
this would creat a sum of 9+4a+20
now we can add together the like terms which in this case are 20 and 9 making the whole sum 29 +4a
this is how you expand the brackets.
deserving of a brainliest?
Answer: B) 29+4a
Step-by-step explanation:
Distribute the parentheses first as multiplication comes before addition:
9+4(a+5)
9+4a+20
Add 9 and 20:

8[4-x]=7x+2 Solve the equation
Answer:
x=2
Step-by-step explanation:
8x4=32
-x x8=-8x
32-8x=7x+2
+8x on both sides
32=15x+2
32-2=30
30=15x
divided by 2
2=x
Answer:
2[tex]\frac{4}{15}[/tex]
Step-by-step explanation:
First factor our the (4-x): (8*4)(8*x)
Then we have 36 - 8x = 7x + 2
Isolate the x:
32 -2 = 8x + 7x
Simplify both sides:
30 = 15x
Divide both sides by 15
[tex]\frac{30}{15}[/tex] = [tex]\frac{15x}{15}[/tex]
Simplify further if necessary:
x = 2

Question 6 options:
A.a reflection across the x-axis
B. a counter-clockwise 90 degree rotation about the origin
C. a reflection across the y-axis
D. a translation 3 units down and 7 units left
Answer:
a counter-clockwise 90 degree rotation about the origin
Step-by-step explanation:
Answer:
ANSWER IS C The transformation below that caused AB to transform into A'B' is a reflection across the y-axis
How to translate a coordinate point to another
Given the following coordinates
A = (6, 2)
B = (2, 6)
A' = (-6, 2)
B' = (-2, 6)
According to the reflection rule, the reflection over y axis is given as:
Note that the x-coordinate was negated as seen from the translation A to A' and B to '.
Hence the transformation below that caused AB to transform into A'B' is a reflection across the y-axis

What is 0.45 divide 9 =
Answer:
0.05
Step-by-step explanation:
If dividing 9 by 0.45, basically .45/9, then you would get 0.05. :) You would need to use division, and move the places 2 over since there is a decimal.
The requried, 0.45 divided 9 gives the quotient of 0.05.
What is arithmetic?In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
Here,
To divide 0.45 by 9, we can write it as a fraction and simplify it:
0.45 ÷ 9 = 0.45/9
We can simplify the fraction by dividing both the numerator and denominator by 9:
0.45/9 = (0.45 ÷ 9)/(9 ÷ 9)
= 0.05/1 = 0.05
Therefore, 0.45 divided by 9 is equal to 0.05.

The balcony of an apartment is 4 feet wide by 7 feet long. On a scale drawing of the apartment, the balcony is 0. 8 inch wide by 1. 4 inches long, and the kitchen is 2. 4 inches wide by 2. 8 inches long. What is the actual width of the kitchen? Enter your answer in the box. The actual width of the kitchen is feet.
For an apartment, the scale factor of the map is 1/60 and the kitchen's actual width of the is 12 ft wide.
What is scale factor?Scale factor is the factor which is used to enlarge or smaller the original figure.
Scale factor is the ratio of representation measurement of the figure to the original figures.
The balcony of an apartment is 4 feet wide by 7 feet long. On a scale drawing of the apartment, the balcony is 0. 8 inches wide by 1. 4 inches long.
The actual length of the balcony is 7 feet or 84 in (1 ft = 12in), and on scale the length of the balcony is 1.4 in. Thus, the scale factor is,
[tex]r=\dfrac{1.4}{84}\\r=\dfrac{1}{60}[/tex]
Thus, the scale factor is 1/60.
The length of the kitchen is 2.8 in on map. Let L is the actual length of the kitchen. Therefore,
[tex]r=\dfrac{2.8}{L}\\\dfrac{1}{60}=\dfrac{2.8}{L}\\L=168\rm in\\L=14\rm ft[/tex]
The width of the kitchen is 2.4 in on map. Let W is the actual width of the kitchen. Therefore,
[tex]r=\dfrac{2.4}{W}\\\dfrac{1}{60}=\dfrac{2.4}{W}\\W=144\rm in\\W=12\rm ft[/tex]
Thus, For an apartment, the scale factor of the map is 1/60 and the kitchen's actual width of the is 12 ft wide.

It takes 2 cups of flour to make 24 cookies. How much flour will it take to make 60 cookies?
Answer:
5 cups of flour needed to make 60 cookies.
Step-by-step explanation:
24 cookies → 2 cups of flour
1 cookies → (2/24) cups of flour
60 cookies → [(2/24)*60 ] cups of flour
60 cookies → 5 cups of flour needed
Answer:
5 cups
Step-by-step explanation:
If 2 cups makes 24 cookies, then 1 cup makes 12 cookies. Since 12 times five is 60, 1 cup of flour filled five times makes 60 cookies so you will need 5 cups of flour.

Three friends decide to share the cost to rent an apartment equally. The apartments that they are considering cost at least 1 200 per month. Write and solve an inequality to represent each person's share of the rental cost
Lets highlight some key words.
There are three friends and they equally have to share an unknown amount of number to earn up to the 1200 per month,
X=Amount needed to pay the rent fee.
Since there are 3 friends and they have to split we have to multiply,
3x, "At least" is less than or equal to so .
3x [tex]\leq[/tex]
Additionally theres 1200 per month so the friends need to share there rent and 1200 is the total it should be put as
3x [tex]\leq[/tex] $1200
To add up to the rent, and to solve the inequality
we have to do the opposite of multiplication, and divide.
1200/3 = 400, x [tex]\leq[/tex] 400
