please help stuck on this question
Answer:
C) 30
Step-by-step explanation:
As, angle 8 = 150°
So angle 6 = 30°
As, they are supplementry to each other
Now, Angle 5 + Angle 6 = 180°
So,as angle
So, Angle 5
Angle 5 + 30° = 180°
Angle 5 = 180° - 30°
Angle 5 = 150°
So therefore, Angle 5 = 150°

Answer:
2x^2 + 6x + 2
Step-by-step explanation:
5 + 3x - x^2 + (3x^2 - 5x + 4 + 8x - 7) =
= 5 + 3x - x^2 + 3x^2 + 3x - 3
= 2x^2 + 6x + 2

Answer the ? Mark pls
Answer:
y=4
Step-by-step explanation:
-28 divided by -7 equals to 4
Hope this helps!!
Answer: y = 4
Step-by-step explanation:
-7y/-7 = -28/-7 So, Both the -7's cancel out and your left with y= you divide -28 by -7. When you divide both of the numbers you get a positive 4.

The Math Club is raising money so they can attend a local competition next month. They have already raised $125 and they are selling candy bars to raise the rest of the money needed. Each candy bar sells for $2.50.
Answer: 100 candy bars
Step-by-step explanation:
You did not include the question but judging by the progression I can assume that the question is along the lines of how many candy bars they will need to sell to reach their target.
You did not include the amount they have to raise as well so let us assume that number is $375.
Assuming they have to raise $375 and they have already raised $125, the amount left to be raised is:
= 375 - 125
= $250
With each candy bar selling at $2.50, the number of candy bars they will need to sell is:
= 250/ 2.50
= 100 candy bars
You should use this process to find the answer to your question.
The hypotenuse of a 45°-45°-90° triangle measures 7 StartRoot 2 EndRoot units.
A right triangle is shown. The hypotenuse has a length of 7 StartRoot 2 EndRoot and the lengths of the other 2 sides are congruent.
What is the length of one leg of the triangle?
7 units
7 StartRoot 2 EndRoot units
14 units
14 StartRoot 2 EndRoot units
Answer:
7 units
Step-by-step explanation:
Given is a 45°-45°-90° triangle.
Measure of Hypotenuse = 7 StartRoot 2 EndRoot units.
In a 45°-45°-90° triangle, measures of perpendicular legs is one upon square root 2 times of the measure of Hypotenuse.
[tex] \therefore \: measure \: of \: one \: leg \\ \\ = \frac{1}{ \sqrt{2} } \times 7 \sqrt{2} \\ \\ = 7 \: units[/tex]

Step-by-step explanation:
Write an equation of the line that passes through the given points.
(2,6) (-4,-2)
Answer:
y = 8/6x + 10/3
Step-by-step explanation:
You find the slope (m) first which is
Change of y over change of x
(6) - (-2) over (2)- (-4)
8/6 = m
Then you plug it into the equation y = mx + b
y = (8/6)x + b
Now you pick any of the set of points to plug in for x and y to solve for b
(6) = (8/6)(2) + b
6 = 8/3 + b
b = 10/3
Then plug into the equation for just m and b to get the equation of the line that passes thru both sets of points.
y = 8/6x + 10/3
what is the rate of change for the function y= 5x+ 25
Answer:
5
Step-by-step explanation:
100% right!!
Answer:

rate of change is the same thing as slope (or m)
solve for X: 3х + 4 = 9x + 3
Answer:
x=1/6
Step-by-step explanation:
The steps are in the picture below
Answer:
Step-by-step explanation:
here you go mate
step 1
3х + 4 = 9x + 3 equation
step 2
3х + 4 = 9x + 3 simplify
-6x+4=3
step 3
−6x+4=3 subtract 4 from both sides
−6x+4(-4)=3(-4)
-6x=-1
step 4
[tex]\frac{-6x}{-6} =\frac{-1}{-6}[/tex] divide both sides
answer
x=[tex]\frac{1}{6}[/tex]

The length of an island is decreasing a rate of 16 inches per year. How many years will it take for the change in length of the island to be -364 inches? Answer value
Answer: 23 years
Step-by-step explanation:
From the question, we are informed that the length of an island is decreasing a rate of 16 inches per year. The number of years that it will take for the change in length of the island to be -364 inches would be gotten by dividing 364 by the rate of decrease every year which is 16 inches. Therefore, this would be:
= 364 / 16
= 22.75 years
= 23 years approximately
