6x + 8x + 7 + 8x - 3 = 180
Simplify
22x + 4 = 180
Minus 4 from both sides
22x = 176
Divide 22 by both sides
X = 8
Can I get brainliest answer
Answer:
x = 8
Step-by-step explanation:
All angles of a triangle must add up to 180 degrees.
So 8x + 7 + 6x + 8x - 3 = 180
Combine like terms
22x + 4 = 180
Subtract 4
22x = 176
Divide
22x ÷ 22 = 176 ÷ 22 = x = 8
We can make sure this is correct by plugging in 8 for all x terms.
8(8) + 7 + 6(8) + 8(8) -3
64 + 7 + 48 + 64 - 3 = 180.
X = 8
Hope this helps.

Describe and correct the error in evaluating the expression. -10^2 = 100
Answers
Answer:
-10² = -100
Step-by-step explanation:
The error in the evaluation occurred when the negative base (which is -10) was squared altogether outside of the parenthesis. (-10²) still results in -100.
The only time that the result will produce a positive 100 is when you square -10 this way: (-10)² = 100 because the negative sign is included with the squaring of base through the parenthesis.
Hope this helps.

2. Find the length of the rectangle.
Answers
Answer:
10.5 unitsStep-by-step explanation:
Given
Perimeter P = 34 unitsWidth w = 6.5 unitsLength l = ?Equation, in terms of l:
2(l + 6.5) = 34l + 6.5 = 17l = 17 - 6.5l = 10.5Answer:
Equation:6.5 + 6.5 + L +L =34
Answer: 10.5
Step-by-step explanation:
To find perimeter you need L+W+L+W. You have a width of 6.5. When you plug that into the equation you get 6.5 + 6.5+ L+L=34. Combine like terms (6.5 +6.5). That leaves you with 13 + 2L = 34. Now, you want to subtract 13 from both sides to isolate the L. You now have 2L = 21. Now you should divide everything by 2. 21/2 = 10.5

Step-by-step explanation:
m= y2 - y1/ x2 - x1( slope of a line)
m = 8 -0 / 7- 0
8/7 = m
m = 1.1
since m =y - y1/ x - x1
1.1 = y - 0/ x-0
1.1 = y/x(cross multiply)
y = 1.1 x
y -1.1 x = 0
or
y - 8/7 x = 0
The sum of the first 21 terms of the progression, - 18, - 15,-12.....is?
Answers
The sum of 21 terms is -1080.
What is Arithmetic Progression?A series in which the differences between each pair of following terms are the same is known as an arithmetic progression.An arithmetic progression is a sequence in which every phrase—aside from the initial term—is created by multiplying the previous term by a predetermined amount.given:
- 18, - 15,-12.....
First term, a= -18
common difference, d= -15 + 18= -3
So, [tex]S_{21[/tex] = 21/2 [ 2(-18)+ (21- 1) (-3)]
[tex]S_{21[/tex] = 21/2 [ -36 + (20) (-3)]
[tex]S_{21[/tex] = 21/2 [ -36 - 60]
[tex]S_{21[/tex] = 21/2 (-96)
[tex]S_{21[/tex] = 21 x (-48)
[tex]S_{21[/tex] = -1008
Hence, the sum of 21 terms is -1080.

Answer:
120 cans of soda were sold
Step-by-step explanation:
Sally's Soda company makes $1.20 for each can of soda sold out of a machine. If the company makes $144, how many
cans of soda were sold?
144 ÷ 1.20 = cans sold
144 ÷ 1.20 = 120
check your work
120 x 1.20 = 144
If JM=30 and LM=8, what is KM?
Answers
If side JM = 30 and side LM = 8, the length of side KM is equal to 15.49 units.
How to determine the length of side KM?In this exercise, we would assign the variable x to the length of side KM. Based on the information provided about triangle JKM and triangle KML, we can logically deduce the following parameters;
Side JL = [(30 + 8) × x]/2
Side JL = 38x/2
Side JL = 19x.
Since point M is the perpendicular bisector of both triangle JKM and triangle KML, the length of side KM can be calculated as follows;
19x = √[(30² + x²)(x² + 8²)]/2
38x = √[(30² + x²)(x² + 8²)]
By taking the square of both sides, we have:
38²x² = (900 + x²)(x² + 64)
38²x² = 900x² + 57,600 + x⁴ + 64x²
38²x² = 964x² + 57,600 + x⁴
(x² - 240)² = 0
x² = 240
x = √240
x = 15.49 units.
