find the value of x HELP PLS
Answer:
x= 36
Step-by-step explanation:
both angles together are supplementary and will form 180
Therefore, you know the missing angle can be found by substracting 108 from 180
180 - 108 = 72
72 = 2x
Answer:
36°
Step-by-step explanation:
2x+108°=180°
2x=72°
x=36°

I'll do the first two to get you started
See the diagram below for the filled out answers.
====================================================
Problem 1
You are correct in saying that 10 goes in the first box. This is from 2*5 = 10 when you apply the distributive property a*(b+c) = a*b+a*c.
For the next box, you'll have x go inside it. This is because we subtract 2x from both sides and then note how 3x-2x becomes x. This x is found on the right side of the third line.
For the last box, we have 9 go inside it. This is from subtracting 1 from both sides, so 10-1 becomes 9.
Answers:
10x9in that order
====================================================
Problem 2
We add 2y to both sides so that 3y becomes 5y. Ie, 2y+3y = 5y
As a way to check the answer, note how 5y is on the left side of line 2.
Then we'll add 4 to both sides. So 6 updates to 6+4 = 10 on the right side. We type 10 in the second box.
The last step is to divide both sides by 2. The equation 5y = 10 solves to y = 2
Answers:

If you add the two equations 6x + 4y 46 and — 6x + 9y = 6 what do you get?
Answer:
13y = 52
Step-by-step explanation:
6x - 6x + 4y + 9y = (46 + 6)
6x - 6x + 4y + 9y = 52
0 + 4y + 9y = 52
0 + 13y = 52
13y = 52
(p.s. y = 4)

Tangent = Opposite / Adjacent
sin(64) = x / 94
Multiply both sides by 94.

William is planning a party. He spent $110.74 to buy 9.8 pounds of candy for favors. What was the cost per pound of the candy? (Do not include the $ sign in your answer.)
Answer: $11.30 per pound
Step-by-step explanation:
William spent $110.74 to buy 9.8 pounds of candy.
To find the cost per candy, divide the amount spent by the quantity of candy:
=Amount spent on candy / Quantity of candy
= 110.74 / 9.8
= $11.30 per pound
William only had 1 3/4 cups of flour so he can only make 2/3 of a batch of biscuits how much flour is needed for a full batch of biscuits
Answer: 2 5/8 Cups
Step-by-step explanation:
Cups of flour he have = 1 3/4
= 7/4
Batch of biscuits made = 2/3
Flour to make a full batch
7/4 / 2/3 = 2 1/8
= 2 5/8 Cups

23% of what number is 46?
Answer: 200
Step-by-step explanation:
first, you set up your proportion. (23% at the top right, 100 at the bottom right, 46 at the top left, and x and the bottom left.) next, you multiply x * 23% = 23x then 46*100 = 4600. 4600 divided by 23 = 200. therefore, x = 200. please let me know if you have further questions!

30 students in a class went on a trip to the other side of the city. There were 4 vans for the
students to take. 6 students walked. How many students could fit in each van?
Answer:
6
Step-by-step explanation:
30-6=24
(6 people walked which means they are not included in the people fitting on the busses)
24/4=6
(from there you need to divide by 4 to tell how many were on each bus.)

Hope this helped you out :)
Answer:
2π r is how you find the circumference of a circle so the answer is the second option .
∠A and ∠ B ∠B are complementary angles. If m ∠ A = ( x − 23 ) ∘ ∠A=(x−23) ∘ and m ∠ B = ( 2 x + 29 ) ∘ ∠B=(2x+29) ∘ , then find the measure of ∠ B ∠B
Answer:

Step-by-step explanation:
2x + 29 + x - 23 = 180
solve for x = 28
b = 2 * 28 + 29 = 85

Slope of the line :

The slope of line passing through (-2, 7) and (3, 2). is -1 and the value of the y-intercept b is 5.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
A line passes through (-2, 7) and (3, 2). We need to find the slope.
x₁=-2, x₂=3, y₁=7, y₂=2
substitute the values in formula of slope
m=2-7/3-(-2)
m=-5/5=-1
The slope intercept form of line is y=-x+b
To find b put the values of (-2,7)
7=-(-2)+b
7=2+b
7-2=b
5=b
y intercept is 5
Hence the slope of line passing through (-2, 7) and (3, 2). is -1 and the value of the y-intercept b is 5.
