An equation is shown below:
6(2x - 11) + 15 = 3x + 12
Part A: Write the steps you will use to solve the equation, and explain each step. (6 points)
Part B: What value of x makes the equation true? (4 points)
Answers
6(2x-11)+15=3x+12
distribute the 6:
12x-66+15=3x+12
add -66 and 15:
12x-51=3x+12
subtract 3x from both sides:
9x-51=12
add 51 to both sides:
9x=63
divide 9 from both sides:
x=7

a=1/2pa, solve for p
NO LINKS PLEASEE!! IM BEGGING YOU NO LINKSS!!!
Answers
Answer:
A = (1/2)Pa = Pa/2
You can multiply both sides by 2 to eliminate the fraction on the right side:
2A = 2(Pa/2) = Pa
Then divide both sides by a (or multiply both sides by 1/a) to leave P alone on the right side:
(2A)(1/a) = 2A/a = (Pa)(1/a) = P
Rewriting:
P = 2A/a
You could also have divided by a first then multiplied by 2; which you should do first does not matter in this example.

1. mean:10 median:11 mode:13
2. mean:30 median:35 mode: 20
Answer:
1. Mean: 10 Median: 11 Mode: 13
2. Mean: 26.7 Median: 20.5 Mode: 20
Step-by-step explanation:
1. Mean: 6+7+11+13+13 = 50 then, 50/5 = 10
Median: 6, 7, 11, 13, 13 in the middle: 11
6- crossed
13- crossed
7- crossed
13- crossed
That leaves 11!
Mode: 13 appears two times. All the other numbers only appear once.
2. Mean: 0+20+20+30+40+70 = 160 then, 160/6 = 26.7 ( rounded to nearest tenth)
Median: 0, 20, 20, 30, 40, 70
0- crossed
70- crossed
20- crossed
40- crossed
20- crossed
30- crossed
They all are crossed, but the last 2 to be crossed are 20 and 30. The middle of those two numbers is 20.5 therefore, the median is 20.5!
Mode: 20 appears twice while the rest only appears once.
I hope this helps, good luck! :)

Which two parallelograms have the same area?
Answers
Answer:
Idc
Step-by-step explanation:
I don’t really wanna help, so thanks for the points! Don’t scroll down! I’m warning you!!!
Figure 1 and Figure 4 have the same areas because the area of a parallelogram is just length times width.
Figure 1: 15×4=60 cm
Figure 2: 18×3=54 cm
Figure 3: 11×6=66 cm
Figure 4: 12×5=60 cm
As you can see, figure 1 and figure 4 have the same areas. So, C is the correct answer.

Find the value of x:
Answers
Answer:
x = 3
Step-by-step explanation:
These angles are vertical angles. Vertical angles equals to on another but on the opposite side. Since they equal to another you do:
(10x + 1) = (12x - 5)
Add 5 on both sides:
10x + 6 = 12x
Subtract 10x on both sides:
6 = 2x
Divide 2 on both sides:
3 = x
Answer:
(10x+1)°=(12x-5)°. [vertically opposite angle]
1+5=12x-10x
6= 2x
3=x
therefore,x=3

Step-by-step explanation:
1) Check whether the graph is inclusive or exclusive. Inclusive graphs are equal to or greater/less than, whereas exclusive graphs are just greater/less than. A filled circle is inclusive, and a non-filled circle is exclusive. We see that in the graph, the circle is filled meaning it is inclusive. Secondly, we see that the number line goes forever when it is greater than(or equal to) 3. From these two pieces of information, we see that the answer is choice D.

Maggie is buying a jacket. The expression shown represents the sales tax on the jacket price, j.
0.08j
Write an expression in terms of j to represent the total amount that Maggie spends on the jacket, including tax.
Answers
Answer: 1.08j
Step-by-step explanation: if we add 8% of something to itself, we now have 108%, right
1.08j
I’m not 100% sure tho
The expression represents the total amount that Maggie spends on the jacket, including tax is 1.08j.
What is Percentage?A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
As it is given that the cost of the jacket is j, while the tax on the jacket is 0.08j. therefore, the total cost of the jacket can be written as the sum of the cost of the jacket and the tax on the jacket.
Thus, the total cost of the jacket = Cost of jacket + Tax on the jacket
= j + 0.08j
= 1.08j
Hence, the expression represents the total amount that Maggie spends on the jacket, including tax is 1.08j.
