Answer:
a = - 10
Step-by-step explanation:
3a – 8 = 5a + 12
3a – 8 + 8 = 5a + 12 + 8
3a = 5a + 20
3a - 5a = 5a + 20 - 5a
- 2a = 20
[tex]\dfrac{-2a}{-2}=\dfrac{20}{-2}[/tex]
a = - 10

Step-by-step explanation:
Answer:
C. y ≤ 0
D. 18 bags of chips and 6 jars of salsa
Step-by-step explanation:
It is C because, it is over the x axis and it covers all the negative y's.
__________________________________________________________
2.5x + 4y ≤ 60
2.5(10) + 4(2) ≤ 60
25 + 8 ≤ 60
33 ≤ 60
It fits so A doesn't work
2.5x + 4y ≤ 60
2.5(20) + 4(2) ≤ 60
50 + 8 ≤ 60
58 ≤ 60
It fits so B doesn't work
2.5x + 4y ≤ 60
2.5(14) + 4(5) ≤ 60
35 + 20 ≤ 60
55 ≤ 60
It fits so C doesn't work
2.5x + 4y ≤ 60
2.5(18) + 4(6) ≤ 60
45 + 24 ≤ 69
It doesn't fit therefore, your answer would be D. 18 bags of chips and 6 jars of salsa.

What is the image of (−8,−8) after a dilation by a scale factor of 1/2 centered at the origin?
Answer:
(-4,-4)
Step-by-step explanation:
Since this is centered at (0,0), we have to multiply the x and the y coordinates by the scale factor.
-8 × 1/2 = -4

Find slope
11x - 6y = -36
Answer:
11/6
Step-by-step explanation:
To isolate the y on one side of the equation, you must first subtract 11x from both sides. Then the equation becomes -6y = -11x - 36.
Then you must divide both sides by -6 to isolate the y. The coefficient of the variable x becomes -11/-6, which is just 11/6.

Solve the problem:
7 ( w + 3)
whats w?
Answer:
3
(the w is a variable, or a placeholder for the unknown)
Step-by-step explanation:
Distribute:
7*w =7w
7*3=21
so now you have 7w+21
Divide:
now you would divide 21 and 7w by 7, the 7 would get canceled out, so you are left with 21/7 which equals 3

Ms. Ringer asked her class, "What are the favorite colors of the students in our school?" Which student correctly describes Ms. Ringer's question?
Answer:
D
Step-by-step explanation: We know it's not A or B because a statistical question is a question that will vary. D has that exact response while C is not exactly what a statistical question is.
The student who correctly describes Ms. Ringer's question would say that it is an open-ended question.
What is an expression?A term is composed of one mathematical expression. A single variable (a letter), a single integer (positive or negative), or a number of variables that have been multiplied but never added or subtracted are all examples of single variables. There is a number in front of certain words that are variables. A word or phrase is preceded by a coefficient.
Ms. Ringer asked her class, "What are the favorite colors of the students in our school?"

Answer:
11
Step-by-step explanation:
None of these answer choices you have are correct. you have to do parentheses first, which gives you 9 + (3)2/3, then you do division which gives you .6666666666, then you multiply that by 3 and you get 2 and add that to 9

(where the longer it takes to solve a problem and the fewer people who answer it correctly, the more difficult it is). On each subsection, question 1 will be "easy" and question 15 will be considered "difficult." However, the ascending difficulty resets from easy to hard on the grid-ins.
Hence, multiple choice questions are arranged in increasing difficulty (questions 1 and 2 will be the easiest, questions 14 and 15 will be the hardest), but the difficulty level resets for the grid-in section (meaning questions 16 and 17 will again be "easy" and questions 19 and 20 will be very difficult).

Convert 3 weeks to hours. Use a lable.
Answer: 504 hours.
Step-by-step explanation: I am assuming it says, use a table not a lable.
Well, I can't make a table, so I will tell you where to put everything in a table.
We start with placing one day, one day is 24 hours. One day goes on the top, 24 hours goes on the bottom. Then, we know there are 7 days in a week, so we jump ahead, we multiply 24 by 7 and 1 by 7.
24 x 7 = 168 and 1 x 7 = 7
So for every week, it is 168 hours. Now we need to find three weeks. So we multiply 7 x 3 to get the days. which is 21. Now we need to multiply the hours by the 3 weeks. So we multiply 168 by 3 which is 504.
So 504 hours are in 3 weeks.

PLS HELP
Answer:
1) 2x-3 = x -3 + x
2) 2x - 6 = -6 + 2x
3) [tex]\frac{3}{5}-\frac{13}{5}=-6.9+4.9[/tex]
4) 3x+0 = 3x
5) [tex]\frac{5}{3}-x+\frac{1}{3}=-\frac{3}{2}x+2+\frac{1}{2}x[/tex]
Step-by-step explanation:
We need to match each expression on the left with an equivalent expression on the right
The expressions are equivalent if the have the same results.
1) 2x - 3
Looking at the options the best match is:
x -3 + x
When solve we get:
2x-3
So, 2x-3 = x -3 + x
2) 2x - 6
Looking at the options the best match is:
-6 + 2x
Because according to commutative property: a+b = b+a
So, 2x - 6 = -6 + 2x
3) [tex]\frac{3}{5}-\frac{13}{5}[/tex]
First simplifying the given expression:
[tex]\frac{3}{5}-\frac{13}{5}\\=\frac{3-13}{5}\\=\frac{-10}{5}\\=-2[/tex]
Looking at the options, -6.9+4.9 = -2
So, [tex]\frac{3}{5}-\frac{13}{5}=-6.9+4.9[/tex]
4) 3x + 0
Looking at the options the best match is:
3x
Because, adding 0 in 3x will result in 3x
So, 3x+0 = 3x
5) [tex]\frac{5}{3}-x+\frac{1}{3}[/tex]
First simplifying:
[tex]\frac{5}{3}-x+\frac{1}{3}\\=\frac{5-3x+1}{3}\\=\frac{6-3x}{3}\\= \frac{3(2-x)}{3}\\=2-x[/tex]
Now, solving the option: [tex]-\frac{3}{2}x+2+\frac{1}{2}x[/tex]
[tex]=\frac{-3x+4+1x}{2}\\=\frac{-2x+4}{2}\\=\frac{2(-x+2)}{2}\\=-x+2\\or\\=2-x[/tex]
So, [tex]\frac{5}{3}-x+\frac{1}{3}=-\frac{3}{2}x+2+\frac{1}{2}x[/tex]

Step-by-step explanation:
The body of a dump truck is raised to empty a load of dirt. How high is the 10 inch body from the frame when it is tipped upward at 45 degrees
Answer:
7.071inches
Step-by-step explanation:
The set up is a right angled triangle
Given 'angle of elevation = 45 degrees
The length of the frame = 10in (hypotenuse)
Required
Height of the truck h (opposite)
Using the SOH trig identity
sin theta = opposite/hyp
sin 45 = h/10
h = 10sin45
h = 10(0.7071)
h = 7.071 in
Hence the height of the truck is 7.071inches

What percentage of the shape is orange?
Write your answer using a percent sign (%).
(help!) almost done!! I will mark who ever awnser s first as brainliest!
Answer:
40%
Step-by-step explanation:
There are five pieces of a square. Two of the five pieces are shaded in orange, since each piece is 20% and there are two shaded pieces, it is your best bet that your final answer is 40%.
Answer:
40%
Step-by-step explanation:
Since there are only two boxes filled, the fraction would be 2/5. Now, by applying that knowledge, you can see that the bow is filled 40% of the way with orange. An easy way to figue this out would be to divide 2 by 5 and get the decimal of .4 which as a percentage would be 40%. Hope this helped!

The sugar is sold at & 5.4 per kg at
At what price should it be sold per kg to com
a profit of 20%
the sugar is sold at rupees 5.4 per kg at a loss of 10% at what price should it be sold per kg to earn a profit of 20%
Answer:
7.2 rupees
Step-by-step explanation:
Given that at a loss of 10 percent which is 90% price, we have sugar sold at 5.4 rupees per k.g
Hence, at 100 percent we have => 5.4 × (100 ÷ 90 )= 6 rupees per kg.
Therefore, at 100 percent, where we have 6 rupees per kg, to make a profit of 20% we have
6 rupees per kg x 120% = 6 × 1.2 = 7.2 rupees per kg.
Hence, the final answer is 7.2 rupees per kg to make a profit of 20%.

Step-by-step explanation:
You live in a big apartment. The bedroom is 15 by 20 feet. Calculate the area of your bedroom.
a.
100 sq. ft
c.
180 sq. ft
b.
300 sq. ft
d.
70 sq. ft
Answer:
The answer is B 300 sq. ft.
Step-by-step explanation:
If you multiply 15 by 2 you were to get 30 but since it is 15 multiplied by 20 instead its like adding a 0 at the end of the number so we change 30 to 300.
Hope this helps :)
