Answer:
B: 3x+(4x+2)=180
Step-by-step explanation:
Supplementary angles are those angles that sum up to 180 degrees. The question gives you the two angles that compose the 180 degree angle thus you get the equation:
Angle 1 + Angle 2 = Supplementary Angle
In this case we see that these two angles are Angles B and C and a supplementary angle is 180 degrees thus:
(4x+2)+3x = 180
Furthermore this also allows you to find x.

12 is the population mean or sample mean of given data.
Given that
The collected data
17, 10, 3, 5, 25
To find
The population mean or sample mean
So, according to the question
we have,
The collected data
17, 10, 3, 5, 25
For calculate the the population mean or sample mean, We have to find out the total of data, and total number of data.
Total of data = 17+ 10 +3 + 5+ 25
Total of data = 60
Total number of data (n) = 5,
So, we know that
Sample mean = [tex]\frac{total\;of\;data}{n\;number\;of\;data}[/tex]
Now, putting the all values,
We will get,

Enter your answer, in the form (x,y,z), in the boxes in simplest terms.
The solution of the system of linear equations is (x, y, z) = (1, 1, - 3).
How to resolve a system of linear equations
In this problem we find a system of three linear equations with three variables, which can be resolved by several methods. In this case, we shall use the method of substitution. First, clear the variable x in the third equation:
x = 4 - 3 · y
Second, substitute x in the first two equations:
3 · (4 - 3 · y) + 2 · y - z = 8
12 - 9 · y + 2 · y - z = 8
- 7 · y - z = - 4
2 · (4 - 3 · y) + 2 · z = - 4
8 - 6 · y + 2 · z = - 4
- 6 · y + 2 · z = - 12
Third, clear z in the first equation derived in the previous step:
z = 4 - 7 · y
Fourth, substitute z in the second equation derived in the second step:
- 6 · y + 2 · (4 - 7 · y) = - 12
- 6 · y + 8 - 14 · y = - 12
- 20 · y = - 20
y = 1
Fifth, calculate y and x:
z = 4 - 7 · 1
z = - 3
x = 4 - 3 · 1
x = 1
The solution of the system of linear equations is (x, y, z) = (1, 1, - 3).

Rochelle needs to pack a picture frame that measures 7611 inches on each side. Will it fit into a box that measures 7.52 inches on each side? Explain.
No, the picture frame will not fit into a box that measures 7.5 inches on each side because the side of the frame will be greater than it that is 7.54 inches.
Length of picture frame is given as:
= 7 (6 / 11)
= 7.54 inches
The length of Box is given as = 7.5 inches
From the above, we can see that the length of the box is smaller than the length of the picture frame.
So, the picture frame will not be able to fit in the box.
Therefore, we get that, the picture frame will not be able to fit into a box that measures 7.5 inches on each side because the side of the frame will be greater than it that is 7.54 inches.

Find y if the slope between (1,y) and (-5,-1) is 2/3
Answer:
y = 3
Step-by-step explanation:
Points: (1, y), (-5, -1)
slope = (y_2 - y_1)/(x_2 - x_1)
slope = (-1 - y)/(-5 - 1) = (-1 - y)/(-6)
slope = 2/3
(-1 - y)/(-6) = 2/3
Multiply both sides by -6.
-1 - y = -6 × 2/3
-1 - y = -12/3
-1 - y = -4
-y = -3

Sid makes a living baking cakes. For each cake, he uses 1 3/4 cups of sugar, 4 1/5 cups
of flour, and 3/10 of a cup of milk. How many cups of ingredients will Sid need to
make 4 cakes? Please I need the answer
By adding the number of cups needed for each cake, we conclude that you will need 25 cups of ingredients to make the 4 cakes.
How many cups of ingredients sill Sid need for 4 cakes?We know that the recipe calls for:
(1 + 3/4 ) cups of sugar.(4 + 1/5) cups of flour.3/10 of a coup of milk.That is for a single cake, so in a single cake you need a total of cups given by the sum of the above quantities, this gives:
(1 + 3/4) + (4 + 1/5) + 3/10 = (1 + 4) + (3/4 + 1/5 + 3/10)
= 5 + (3/4 + 2/10 + 3/10) = 5 + (3/4 + 5/10) = 5 + (3/4 + 1/2) = 5 + 5/4
= 5 + 4/4 + 1/4 = 6 + 1/4
Each cake needs (6 + 1/4) cups of ingredients, so 4 cakes will need:
4* (6 + 1/4) = 24 + 4/4 = 25
You will need 25 cups of ingredients to make the 4 cakes.

with measurement BC = 60, CD = 50.
Triangle RST : RS = 11x-4, ST = 70
What is similarity?Two figures are said to be similar if they are the same shape. In more mathematical language, two figures are similar if their corresponding angles are congruent , and the ratios of the lengths of their corresponding sides are equal.
Given:
BC = 60 and CD = 50
RS = 11x - 4 and ST = 70
Now, considering
BC : CD = RS : ST
60 : 50 = 11x - 4 : 70
60/50 = (11x - 4)/70
50 * (11x - 4) = 70 * 60
11x - 4 = 84

Two boy scouts were selling popcorn for a fundraiser at a local grocery store and made $640. They sold twice the amount of kettle corn as butter popcorn, and 6 more bags of cheddar popcorn than kettle corn. If kettle corn cost $15 a bag, butter popcorn cost $8 per bag, and cheddar popcorn cost $10 per bag, how much of each type of popcorn did they sell? Write an equation to solve the problem.
They sold 10 bags of butter popcorn, 20 bags of kettle corn and 26 bags of cheddar cheese.
Here, we are given that two boy scouts were selling popcorn for a fundraiser.
Their total revenue = $640
Let the bags of butter popcorn be x
then, the bags of kettle corn sold = 2x
and the bags of cheddar popcorn sold = 2x + 6
Cost of kettle corn = $15/ bag
Cost of butter popcorn = $8/ bag
Cost of cheddar popcorn = $10/ bag
Thus, the total revenue from from kettle corn = $30x
total revenue from from butter popcorn = $8x
total revenue from from cheddar popcorn = $10(2x + 6)x
Thus, we will get the following equation-
30x + 8x + 10(2x + 6) = 640
38x + 20x + 60 = 640
58x + 60 = 640
58x = 580
x = 580/ 58
x = 10
Thus, 2x = 20 and 2x + 6 = 26
Hence, they sold 10 bags of butter popcorn, 20 bags of kettle corn and 26 bags of cheddar cheese.

The required measure of the angle m∠B is 121°.
Given that,
Angle A and B are two vertical equal angles.
m∠B = 3x - 17
m∠A = 2x + 29
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
m∠A = m∠B

If two years ago, his account was worth $215,613. After losing 13 of its original value, it then gained 12 of its new value back. The current value of his Roth IRA is: $215,613.
Current valueFirst step is to calculate the value loss
Value loss=1/3× original value
Value loss= 1/3× $215,613
Value loss= $71,871
Second step is to calculate the new value
New value=$215,613-$71,871
New value= $143,742
Third step is to calculate the value gained
Value gained= 1/2× new value
Valued gained=1/2× $143,742
Valued gained=$71,871
Fourth step is to calculate the current value
Current value= $143,742+$71,871
