Step-by-step explanation:
All triangles (3 sided polygons) have angles added up to 180, so we can do the following:
(7x-1) + (7x+8) + (5x+2) = 180° - equation
7x-1 + 7x+8 + 5x+2 = 180° - "distribute"
19x - 1 + 8 + 2 = 180° - combine the x terms
19x + 9 = 180° - combine the integer terms
19x = 171 - subtract 9 form both sides
x = 9 - divide both sides by 19

Which inequality below satisfies the solution set graphed on the following number line?
Answers
Answer:
D.
Step-by-step explanation:
The function must have the range -3 to 5.
2x^2 - 4x - 30
= 2(x^2 - 2x - 15)
= 2(x + 3)(x - 5)
so the critical points are -3 and 5.
When x = -2 f(x) = 2* 1 * -7 = -14 <= 0
when x = 4 f(x) = 2 * 7 * -1 <= 0.
when x= 0 f(x) < 0
So its the last option.

Answers
Answer:
[tex] \frac{7}{17} [/tex]
Step-by-step explanation:
(-14) ÷ (-34)
14/34
= ⁷/17
The quotient of the division will be 0.41. And the solution of the division (−14) by (−34) would be 7/17 as a simplified fraction.
How can we interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.
We need to divide the mixed fraction with integers, So
(-14) ÷ (-34)
The common denominator we can calculate as the least common multiple of the denominators then we get
14/34
= 7/ 17
= 0.41
Thus, the quotient of the division will be 0.41
Therefore, the solution of the division (−14) by (−34) would be 7/ 17 as a simplified fraction.

Hello There!
Solving inequalities is almost like solving equations.
x<11.
Let me explain step-by-step.
3x<36-3
3x<33
x<11
We must isolate x.
x < 11 means x is less than 11.
It could be 10, -100, as long as it is less than 11, it would make the inequality true.
Let's verify.
3(10)+3<36
30+3<36
33<36
It's true, isn't it?
Hope it helps! :)

What are the range of all integers greater than 40 and less than 99 that are multiples of 3?
Answers
We want to find the total number of integers that are larger than 40 and smaller than 99 that also are multiples of 3.
The answer is 18.
We can solve this just by counting.
The first multiple of 3 larger than 40 is:
3*14 = 42
Now we know that 99 is also a multiple of 3 and that the multiples of 3 are separated by a distance of 3 units, then the total number of multiples of 3 between 42 and 99 is given by:
(99 - 42)/3 = 19
But we need to remove 1, because we used 99 and we have the restriction that our numbers must be "smaller" than 99.
Then we have a total of 18 multiples of 3 between 40 and 99.

-12 goes on the x axis (the line that goes ⇄), and because it's negative, it will go to the right.
start from that point (-12 on the x axis) and start going down till you reach -52 on the y axis (the line that goes ⇅)

Over 25.5 days a ponds water level changed by a average of -0.32 centimeter each day what was the total change in the water level
A:10.55
B:-8.16
C:8.16
D:-10.55
Answers
If over 25.5 days a ponds water level changed by a average of -0.32 centimeter each day the total change in the water level will be: C:8.16
Centimeter each day=-0.32
Days of changed in water level=25.5 days
Now let determine total change in the water level
Total change=25.5 days × (-0.32)
Total change=8.16 centimeter
Inconclusion if over 25.5 days a ponds water level changed by a average of -0.32 centimeter each day the total change in the water level will be: C:8.16

The area in square feet of a rectangular field is x^{2}-110x+2800. The width, in feet, ix x-40. What is the length, in feet?
Answers
Answer: I changed 2 items ({2} and ix), so review carefully. The length is (x-70) feet.
Step-by-step explanation:
Area = x^2 - 110x+2800
Width = (x-40)
Area = Width x Length
(x^2 - 110x+2800) = (x-40)*L
L = (x^2 - 110x+2800)/(x-40)
L = (x - 40)(x-70)/(x-40) Factor the numerator.
L = (x - 70) feet
