which property justifies step 3 Given: 4(x - 6) + 12 = 20
Answer:
x=8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4(x−6)+12=20
(4)(x)+(4)(−6)+12=20(Distribute)
4x+−24+12=20
(4x)+(−24+12)=20(Combine Like Terms)
4x+−12=20
4x−12=20
Step 2: Add 12 to both sides.
4x−12+12=20+12
4x=32
Step 3: Divide both sides by 4.
4x

the length of a boat is 10.8 m Boris buys a scale model of the boat the scale of the model is 1 to 18 work out the length of the scale model of the boat give your answer in centimetres
Answer:
The size of the scale model is 60 centimeters.
Step-by-step explanation:
Given that the length of a boat is 10.8 m, and Boris buys a scale model of the boat whose ratio is 1 to 18, to determine the length of the scale model of the boat in centimeters the following calculation must be performed:
1m = 100cm
10.8 m = (10.8 x 100) = 1080 cm
1080/18 = X
60 = X
Therefore, the size of the scale model is 60 centimeters.

11g − 5g + –17g − –7g = –12
Answer:
g=3
Step-by-step explanation:
11g-5g+-17g-(-7g)=-12
Add the like terms (nice that in this case they are all on the same side)
6g+-17g-(-7g)=-12
-11g-(-7g)=-12
-4g=-12 Now we divide (phew that was a lot of negatives XD)
g=3

There are 18 girls in Mr. Brimley's math class. If 40% of the students are girls, what is the best estimation for the number of boys in the class?
Answer:
30
Step-by-step explanation:
This is an easy one.
So, we know that 40% of the class is girls. We would need to use the other 60% as 60% of the class is boys and we would need to divide.
18/0.6=30
Therefore your answer is 30.
Hope this helps.
Answer:
20
Step-by-step explanation:
It is 40 percent ( given)
18/2=9
9×5=40 (100%)
Girls- 18( given)
Boys- 40-18=22

use substitution to solve the system of equations. Write the solution as an ordered pair.
x + 2y = 14
y = 3x - 14
Answer:
Step-by-step explanation:
x + 2(3x - 14) = 14
x + 6x - 28 = 14
7x - 28 = 14
7x = 42
x = 6
y = 3(6) - 14
y = 18 - 14
y = 4

an Italian restaurant buys 15 pounds of onions every 2 weeks. how many bags of onions will the restaurant buy in 7 weeks?
Answer:
45
Step-by-step explanation:
This is a trick question. Since they only get three purchases in by 7 weeks, the answer will be 15 times 3 or 45.
(If I'm wrong and it's not a trick question, then it's 15 times 3.5 or 52.5)
Hope this helps!
system of equations
Answer:1:(2,7)
2:i or (1,-3)
3:is c or (-15,-25)
Step-by-step explanation:like if this helped mark me brainlest please
Answer:
(2,7)
(1,-3)
(-15,-25)
Step-by-step explanation:
Because both equations are equal to the same thing (y) we can just set them equal to each other and solve for x
4x-1=2x+3
solve for x
4x=2x+4
2x=4
x=2
We know that x=2 and can plug this value in for x into any of the beginning equations
4(2)-1=y
7=y
The answer is (2,7)
2.) We can do the exact same process as question one
x-4= -3x
-4= -4x
x=1
plug this x value in into any of the starting equations
1-4=y
-3=y
The answer is (1,-3)
3.) Same deal as the other two
x-10=2x+5
-x=15
x= -15
Plug this value in for x into any beginning equation
2(-15)+5
-30+5
y= -25
(-15,-25)

Answer:
A. only inequality 1.
Step-by-step explanation:
The inequality 1 can be written as
- 5 = 1 - 3d
- 5 - 1 = - 3d
- 3d = - 6
d = 2
Now the inequality 2 can be written as
- 1 =( 1 - d) / 3
- 3 = 1 - d
d = 1 + 3
d = 4
So the answer is A only inequality 1.
Hope it will help :)

Answer:
p : q = 3 : 2
Step-by-step explanation:
You are given sufficient information to write two relations involving p and q. We presume these will be sufficient to find an answer to the question. We will be able to find p and q. Then we can find their ratio, as the problem asks.
(p-15)/(q-15) = 2/1
(p+30)/(q+30) = 5/4
__
From the first equation, we get ...
p -15 = 2(q -15)
p = 2q -15 . . . . . . . add 15, simplify
From the second equation, we get ...
4(p +30) = 5(q +30)
4p + 120 = 5q + 150
4p = 5q + 30
Using the first equation to substitute for p, we have ...
4(2q -15) = 5q +30
8q -60 = 5q +30 . . . eliminate parentheses
3q = 90 . . . . . . . . . . . add 60-5q to both sides
q = 30 . . . . . . . . . . . . divide by 3
p = 2q -15 = 2(30) -15 = 45
Then the desired ratio is ...
p : q = 45 : 30
p : q = 3 : 2

Step-by-step explanation:
Answer:
A 140
Step-by-step explanation:
Mark the center of the circle as O. It's given that
∠IOJ = 70°
∠JOK = 70°
from the drawing it looks like HOI, IOJ and JOK are supplementary angles, which means that they add up to 180°
∠HOI + ∠IOJ + ∠JOK = 180°
∠HOI = 180° - ∠IOJ - ∠JOK
∠HOI = 180° - 70° - 70°
∠HOI = 40°
∠HOI and ∠KOL are cross angles, therefore ∠HOI = ∠KOL = 40°
Since ∠HOL and ∠KOL are supplementary angles
∠HOL = 180° - ∠KOL
∠HOL = 180° - 40°
∠HOL = 140°

Lorenzo ate 25 of his bag of almonds. His 4 friends ate equal shares of the remaining bag of almonds. Which expression represents the almonds that each friend ate?
Answer:
(x - 25) / 4
Step-by-step explanation:
In this scenario, we have one unknown variable which is the total of the bag of almonds, therefore we can represent this with the variable x. Since Lorenzo ate 25 of this bag we would need to subtract this from the total of the bag. Then we need to divide the remainder by 4 since each of his friends ate the rest in equal parts. This would leave us with the following expression ...
(x - 25) / 4
