Equality PropertiesStep-by-step explanation:
Step 1: Define
a(c + b) = d
Step 2: Solve for c
Divide a on both sides: c + b = d/aSubtract b on both sides; c = d/a - bPls help, The graph of a proportional relationship contains the point (20, 4) .

Amitas kitchen is rectangular with an area of 3 3 4 square meters the width of the kitchen is 1 1 2 meters what is the length in meters of amitas kitchen
Answer:
2 1/5 meters
Step-by-step explanation:
Given that:
Area of kitchen = 3 3/4
Width of kitchen = 1 1/2
Length = x
Recall : Area of rectangle = Length * width
Area of kitchen = length * width
3 3/4 = x * 1 1/2
15 / 4 = x * 3/2
x = 15/4 ÷ 3/2
x = 15/4 * 2/3
x = 30/12 = 2 6/30
x = 2 1/5
Which equation represents the vertical line passing though (1,-9)
Answer:
x=1
Step-by-step explanation:
To get the vertical line you leave out the y. Since it goes up in all y's, and then you only need the 1 for the x. easy peasy once you know what it is.

Which number sentence is true?
A. -1/12 times 6/7 = -1/14
b. -1/12 times (-6/7)= -1/14
c. 1/12 times 6/7 = -1/14
d.1/12 times (-6/7) = 1/14
Answer:
We conclude that:
[tex]-\frac{1}{12}\cdot \frac{6}{7}=-\frac{1}{14}[/tex]
Hence, option (A) is true.
Step-by-step explanation:
Let us solve the expression
-1/12 times 6/7 = -1/14Let us solve the L.H.S to check whether it becomes equal to R.H.S
[tex]-\frac{1}{12}\:\times \frac{6}{7}[/tex]
Factor the number: 12=6×2
[tex]-\frac{1}{6\cdot \:2}\cdot \frac{6}{7}[/tex]
Cross - cancel the common factor
[tex]-\frac{1}{2}\cdot \frac{1}{7}[/tex]
[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\cdot \frac{c}{d}=\frac{a\:\cdot \:c}{b\:\cdot \:d}[/tex]
[tex]-\frac{1\cdot \:1}{2\cdot \:7}[/tex]
Multiply the number: 7×2 = 14
[tex]-\frac{1}{14}[/tex]
Therefore, we conclude that:
[tex]-\frac{1}{12}\cdot \frac{6}{7}=-\frac{1}{14}[/tex]
Hence, option (A) is true.

In Louisville, 40% of the population is female and 60% are males. 36% of Louisville's population is under 18. The ratio of males to females who are under 18 is 2:1. If there are 1,176 males who are under 18, what is the population of females who are over 18.
Answer:
1411 females
Step-by-step explanation:
Given that:
Male population = 60%
Female population = 40%
36% of total population are under 18
Ratio of male to female under 18 = 2 : 1
Males under 18 = 1176
Females over 18 =?
The population of females under 18:
If males under 18 = 1176
Then female under 18 = 1176 / 2 = 588
Hence number of population under 18 = (1176 + 588) = 1764
1764 = 36% of the entire population
Hence, (100 - 36)% = 64% of the entire population are over 18
1764 = 0.36
x = 0.72
x = (0.72 * 1764) / 0.36
x = 3528
Hence, 40% of the population above 18 are female
0.4 * 3528 = 1411.2
= 1411 females are over 18

12. You are at a carnival and you can spend no more than $15 on games. If you spent $8.75 already, how much money do you have left to spend? Write an inequality and solve.
15-8.75= 7.25
That is the answer
if A # B means the same thing as 2 A- B, then 1 # ( (2 # 3 ) # 4) equals:
By definition of #,
2 # 3 = 2•2 - 3 = 4 - 3 = 1
(2 # 3) # 4 = 1 # 4 = 2•1 - 4 = 2 - 4 = -2
1 # ((2 # 3) # 4) = 1 # (-2) = 2•1 - (-2) = 2 + 2 = 4
The 1 # ( (2 # 3 ) # 4) equals to 4.
Given that,
if A # B means the same thing as 2 A- B.Based on the above information, the calculation is as follows:
By definition of #,
= 2 # 3
= 2(2) - 3
= 4 - 3
= 1
Now
=(2 # 3) # 4
= 1 # 4
= 2(1) - 4
= 2 - 4
= -2
Now
=1 # ((2 # 3) # 4)
= 1 # (-2)
= 2(1) - (-2)
= 2 + 2
= 4

9 1
18 2
27 3
36
45 5
Answer:
9:1, 18:2, 27:3, 36:4, 45:5 or 1,2,3,4,5
Step-by-step explanation:
This is the answer because:
1) We can see that eah ratio is being multiplied with the next number. We can say this because 9 x 2 = 18 and 1 x 2 = 2 which is 18:2 just like that 9 x 3 = 27 and 1 x 3 = 3 which makes the ratio 27:3.
2) If we keep on doing this, 9 x 4 = 36 and 1 x 4 = 4 which makes the ratio 36:4.
Therefore, the answer is 4.
Hope this helps! :D

the rectangular post shown at the right measures 2w-30 by w. the poster has an area of 5400 cm^2. what is The value of w ?
Step-by-step explanation:
w(2w - 30) = 5400
2w²- 30w = 5400
2w² - 30w - 5400 = 0
(w - 60 ) ( w + 45 ) = 0
w= 60 w= - 45
only take the positive value
therefore w = 60
