Answer:
3x +84= 180,
x= 32
Step-by-step explanation:
m∠1 +m∠2= 180° (adj. ∠s on a str. line)
(x +84)° +(2x)°= 180°
x +84 +2x= 180
3x +84= 180
Solving the equation:
3x= 180 -84 (-84 on both sides)
3x= 96
x= 96 ÷3
x= 32

Sofia is a construction manager.She builds 9 house frames, each at a different site. Each frame uses 256 beams. A bundle of 400 beams delivered to each site. How many beams dose it take to build the 9 house frames? How many beams are left over at 9 house sites altogether
Answers
Answer:
2304 beams
1296 beams
Step-by-step explanation:
Total beams to be used in the 9 houses = number of frames needed for a beam x total number of house frames
9 x 256 = 2304
Total beams left over = total number of beams delivered to the 9 houses - total number of beams to be used in the 9 houses
total number of beams delivered to the 9 houses = 400 x 9 = 3600
3600 - 2304 = 1296

Answer:
C. 12
Step-by-step explanation:
To change triangle PQR to XYZ you divide by 4. This can be seen in the change from 12 to 3 on the left side of the triangle. So, you divide 20 by 4 and get 5 and then divide 16 by 4 and get 4.
12/4=3
20/4=5
16/4=4
So, you add these values together to get the perimeter of 12.

Question 10
Liam wants to treat some friends to lunch. He has $50 and knows that lunch will cost $8 per person. For how many people can Liam buy lunch?
A
Liam can buy lunch for 7 or fewer people, including himself.
B
Liam can buy lunch for 7 or more people, including himself.
C
Liam can buy lunch for 6 or fewer people, including himself.
D
Liam can buy lunch for 6 or more people, including himself.
Answers
Answer:
C
Step-by-step explanation:
8 x 6 would equal 48, which results in not having enough money to buy lunch for more people.
Answer:
the answer should be c
Step-by-step explanation:
let's do a equation for this problem.
8x = 50
/8 /8
x = 6.25
x represents the amount of friends. we divide 8 by both sides to isolate x by itself.
since the final result gives us a decimal, we have to round it to the nearest whole number. it's not possible to have a decimal amount of friends. it should be 6. it cannot be 7 if you are wondering because 7 is bigger than 6.25. there's no way there can be 7 friends when there is a limit amount of 6. therefore, the answer is c.

How many solutions does this system
have?
x + 2y = 10
2x + 8y
8y = 16
A. None
B. One
C. Infinite
Answers
Answer:
B. One
Step-by-step explanation:
There is one solution for the given system. The correct answer would be an option (B).
What is the equation?The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.
The system of equations is given in the question, as follows:
x + 2y = 10 ....(i)
2x + 8y = 16 ....(ii)
From equation (i),
x + 2y = 10
x = 10 - 2y .....(iii)
Substitute the equation x = 10 - 2y in the equation (ii), and solve for y
Then we get the value of y = -1
Substitute the equation y = -1 in the equation (iii), and solve for x
So we get the value of x = 12
Thus, there is one solution for the given system.

Answers
Answer:
The value of [tex]x[/tex] is 15.222. We need to use the following equation: [tex]9\cdot x = 137^{\circ}[/tex]
Step-by-step explanation:
From Euclidean Geometry, we know that the sum of measures of internal angles in a triangle equals 180º. Then, we can find the value of [tex]x[/tex] by this formula:
[tex]43^{\circ}+3\cdot x + 6\cdot x = 180^{\circ}[/tex] (1)
[tex]9\cdot x = 137^{\circ}[/tex]
[tex]x = 15.222[/tex]
The value of [tex]x[/tex] is 15.222.

The width of a rectangle is the length minus 6 units. The area of the rectangle is 27 units. What is the length, in units, of the rectangle?
Answers
Answer:
l = 9
Step-by-step explanation:
Create equations w = l - 6, A = 27, so A = l (l-6) so 27 = [tex]l^{2}[/tex] - 6l
so [tex]l^{2}[/tex] - 6l - 27 = 0, by factoring (l-9)(l-3) = 0 so l = 9 or l = 3 since the width can't be negative then l has to be 9 so that w = 9-6 = 3, so width = 3 and l = 9
