While hiking, Sandra went up 120 meters. If Sandra started at 800 meters above sea
level, what is her elevation now?
The Answer:
If Sandra started at 800 meters and went up 120, the answer would be 920.
Step-by-step explanation:
First, simply add 800 meters, which is what she started with. Next, since she has gone up 120 meters since then, and the question is asking us what her elevation is NOW, you can add 800 + 120 to get 920. This question is solved by using addition.

Help! Best answer will get brainiest
Answer:
x=20
Step-by-step explanation:
Complementary means =90 degrees, so with that being said, you need to write the equation as follows:
2x+10+x+20=90
Then add like terms:
3x+30=90
Subtract 30 from both sides (30 and 90)
3x=60
Divide both sides by 3
x=20
I hope this helps!!
What is the equation of the axis of symmetry?
Easy please help
Answer:
[tex]-\frac{b}{2a}[/tex] is the equation for axis of symmetry.
Step-by-step explanation:
b is the second part of the quadratic equation and a is the first part.
For example, [tex]2x^{2} +6x + 4[/tex]
a is 2 and b is 6.
Plug in those values into the equation and then you get the axis of symmetry.

Please help me out :(
Answer:
a)M5=40º
b)M2=140º
c)M2 and M5 are supplementary angles
d)M2 and M5 are same side interior angles
e) A||B
Step-by-step explanation:
Remember that same side interior angles are the angles that are located on the same side of a straight line that cuts through two parallel lines, and these angles are supplementary, meaning that the sum of both of them will always be 180º. So by stating that M5 and M2 add up to 180º and they are on the same side of a straight line cutting through two straight lines we can prove that those two lines are parallel.

A restaurant sells a coffee refill mug for $6.75. Each refill cost $.1.25. Last month, Keith spent $31.75 on a mug and the refills. How many refills did Keith purchase last month? Write and solve an equation to determine the number of refills, r, that Keith purchased.
Answer:
He purchase 20 times.
Step-by-step explanation:
1.25(r)+6.75
1.25(20)+6.75
25+6.75=$31.75

Which statement describes the graph of this polynomial function?
f(x)= x4 + x3 - 2x2
Answer:
NOT c
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
The graph crosses the x-axis at x = 2 and x = –1 and touches the x-axis at x = 0.
The graph touches the x-axis at x = 2 and x = –1 and crosses the x-axis at x = 0.
The graph touches the x-axis at x = –2 and x = 1 and crosses the x-axis at x = 0.
The perimeter of a triangular garden is 78 feet. Find the length of the three sides if the middle length side is 3 feet greater than twice the length of the smallest side, and the longest side is 3 feet less than 3 times the length of the smallest side.
Answer:
36, 29 and 13
Step-by-step explanation:
Let 'a' be the longest side.
Let 'b' be the middle side.
Let 'c' be the smallest side.
From the question given above,
The perimeter of a triangular garden is 78 feet. This can be written as:
Perimeter = a + b + c
78 = a + b + c ...... (1)
The middle length side is 3 feet greater than twice the length of the smallest side. This can be written as follow:
b = 2c + 3 ...... (2)
The longest side is 3 feet less than 3 times the length of the smallest side. This can be written as follow:
a = 3c – 3 ..... (3)
Summary:
78 = a + b + c ...... (1)
b = 2c + 3 ...... (2)
a = 3c – 3 ..... (3)
Substitute the value of a in equation
3 and the value of b in equation 2 into equation 1
78 = a + b + c
b = 2c + 3
a = 3c – 3
78 = (3c – 3) + (2c + 3) + c
78 = 3c – 3 + 2c + 3 + c
78 = 3c + 2c + c – 3 + 3
78 = 6c
Divide both side by 6
c = 78/6
c = 13
Substitute the value of c into equation 2 and 3 to obtain the value of b and a respectively
b = 2c + 3
c = 13
b = 2(13) + 3
b = 26 + 3
b = 29
a = 3c – 3
c = 13
a = 3(13) – 3
a = 39 – 3
a = 36
Therefore, the length of the three sides are: 36, 29 and 13
