Answer:
6a:10b
Step-by-step explanation:
Make both C's equal eachother which we could make 12
4x3=12 and 6x2=12
so we will have to do the same for the other numbers so when 4x3=12 then 2x3=6 and then do the same for 5b where 6x2=12 and 5x2=10
this would make the ratio 6a:12c:10b which would then make the ratio 6a:10b
Solve for y 8x-7y=23 (fill all of the boxes)
Answer:
i think this is the correct answer
Step-by-step explanation:
Simplifying
8x + -7y = 23
Solving
8x + -7y = 23
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '7y' to each side of the equation.
8x + -7y + 7y = 23 + 7y
Combine like terms: -7y + 7y = 0
8x + 0 = 23 + 7y
8x = 23 + 7y
Divide each side by '8'.
x = 2.875 + 0.875y
Simplifying
x = 2.875 + 0.875y

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:
29+4a
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

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.

Find the percentage increase if 60 increases to 99.
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.

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.
