What value of x satisfies the equation below?
12 ( x - 2 ) + 3 x = 1 2 ( x + 6 ) + 2
Answer:
x = 32.6666667
Step-by-step explanation:
12(x - 2) + 3x = 12(x + 6) + 2
Distribute;
12x - 24 + 3x = 12x + 72 + 2
Collect like terms;
15x - 24 = 12x + 74
Subtract 12x from both sides;
3x - 24 = 74
Add 24 to both sides;
3x = 98
Divide both sides by 3;
x = 32.6666667

Objective: Students will use tables to come up with a set of values for a variety of
linear functions and then graph the equations as lines. They will then decorate their
graph paper using colors to create a "stained-glass” look.
Materials:
• Markers, colored pencils, or crayons
• Black marker
• Ruler
• Graph paper (final product looks better with no numbers given, but may
need to use for particular students)
• Student Worksheet
Procedures:
1) Distribute student worksheet. Explain to the students that they are to create
their own set of linear equations (following the requirements below so they
have a variety of positive negative coefficients and constants)
3) y=+_+
1)y=+x
2)y=-x
5)y=-_+
6)y=----
4) y=+_
9)x=+
8)y=-
7)y=+_
IP
2) Give each student time to complete the tables and then distribute a ruler and
black marker. The students should graph each equation, label the equation
on the line and trace it with black marker so it stands out.
3) The last step is for the students to color the sections of the graph paper so it
looks like a stained glass window - I have my students choose just three of
their favorite colors to use.

A train leaves L.A. at 2pm and heads north at 50mph. If the next train leaves the station 3 hours later and heads north at 60 mph, what time will the second train catch up with the first?
Answer:
8 AMStep-by-step explanation:
Start time = 2 PMSpeed of the first train = 50 mphSpeed of the second train = 60 mphTrains head same directionThe second train spends 3 hour less time than the first but both take same distanceLet the time in travel for the first train be x, then we have equation for distance:
50x = 60(x - 3)50x = 60x - 18060x - 50x = 18010x = 180x = 18 hoursTime when the second train caches up the first one:
2 PM + 18 hours = 8 AM next daySolve for x. For the equation

11 more than five of a certain number is twenty more than 2 times of that number. what is the number?
Answer:
Let the number be x
Given:
11 + 5x = 20 + 2x
5x - 2x = 20 - 11
3x = 9
x = 3
The number is 3.
Step-by-step explanation:
Answer:
3
Step-by-step explanation:
Let x represent the number, and set up an equation:
5x + 11 = 2x + 20
Solve for x:
5x + 11 = 2x + 20
3x + 11 = 20
3x = 9
x = 3
So, the number is 3.

What number should be added to both sides of the equation to complete the square?
x2 + 3x = 6
12 / 2
0
Nw
3
62
Answer:
we have added 9/4 to both sides of the equation.
Step-by-step explanation:
The given equation is :
[tex]x^2+3x=6[/tex]
Here, a = 1, b = 3 and c = 6
We should add (b/2)^2 to the both sides of the equation.
(b/2)^2 = (3/2)^2 = (9/4)
[tex]x^2+3x+\dfrac{9}{4}=6+\dfrac{9}{4}\\\\(x+\dfrac{3}{2})^2=\dfrac{33}{4}\\\\x+\dfrac{3}{2}=\pm \dfrac{\sqrt{33}}{2}\\\\x= +\dfrac{\sqrt{33}}{2}-\dfrac{3}{2}, -\dfrac{\sqrt{33}}{2}-\dfrac{3}{2}\\\\=1.37,-4.37[/tex]
Hence, we have added 9/4 to both sides of the equation.

Harry has a total of 90 coins. The coins are either dimes or quarters. If he has 40 quarters, what is the ratio of quarters to dimes? Give your answer as a ratio using a colon in the simplest form.
Answer:
The ratio of quarters to dimes is 4:5 .
Step-by-step explanation: when you subtract 40 from 90, you get 50. If you create a 40:50 ratio, it simplifies to 4:5 .
what is the equation of the graph below?
Answer:
y = 3x + b
3x is the slope
y = 3x + 1 because 1 is the y intercept
Step-by-step explanation:
Answer:
y = 3x + 1
Step-by-step explanation:
You know the y intercept by looking where the line hits the y axis, which is at (0,1), so you know the "b" of the equation is 1. Then, you do rise over run. If you rise 3 and run 1, you get to another point, so I know the slope is 3/1 or 3.
Mr. Lester needs less than 12 cup but more than 13 cup of flour to make a sauce. Which of the following could be the amount of flour that he needs?
1/4 cup
7/12 cup
3/8 cup
7/8 cup
Answer:
3/8 cup
Step-by-step explanation:
To figure out how many cups of flour he could use, let's convert the fractions into decimals. We are told that amount he needs is less than 1/2 and more than 1/3.
1/2 = 0.50
1/3 = 0.33
So, the amount he needs is less than 0.50 and more than 0.33. Now let's convert the answer choices to decimal form:
1/4 = 0.25
7/12 = 0.58
3/8 = 0.38
7/8 = 0.88
The only answer choice that is less than 0.50 but greater than 0.33 is 0.38, or 3/8 cup.
