The sum of a number nd its opposite will always add up to
absolute value?
Answer:
On the number line, a number and its opposite are, predictably, opposite each other. In other words, they are the same distance from zero, but on opposite sides of the number line. The opposite of zero is defined to be simply zero. The sum of a number and its opposite is always zero, as shown in the following example.
16 is 80% of what number?
O A. 20
O B. 12.8
O C. 500
O D. 128
Answer:
A. 20
Step-by-step explanation:
1. To solve this problem, instead of doing 80/100 times 16, we can do 100/80 times 16 (inverse of percentage, basically).
[tex]\frac{100}{80} *16[/tex] [tex]\frac{5}{4} *16[/tex] [tex]\frac{80}{4}[/tex] [tex]20[/tex]Therefore, the answer is A. 20.

3. Wu saved $75 towards a new $250 mountain bike. What percent of the total cost of the bike has Wu saved?
Based on the information given the percent of the total cost of the bike has Wu saved is 30%.
Using this formula
Total cost percentage=Amount saved/Cost×100
Where:
Amount saved=$75
Cost =$250
Let plug in the formula
Total cost percentage=$75/$250×100
Total cost percentage=30%
Inconclusion the percent of the total cost of the bike has Wu saved is 30%.

Given: DE is a midsegment of ∆C. Show all work. Find the value of x and y. What is the length of C?
Answer:
Find out the value of x.
To prove
Definition of mid- segment
It is a segment connecting the midpoints of two sides of a triangle.
It is always parallel to the third side, and the length of the midsegment is half the length of the third side.
As shown in the triangle given below.
As given
DE = 5x and BC = 11x – 15
Thus
15 = 11x - 10x
15 = x
Therefore the value of x is 15 .

A casserole recipes calls for 4 ounces of cheese. Emerson wants to use half of the amount of cheese in his casseroles. How many pounds of cheese will he need to make 28 casseroles with his revised recipe?
Answer:
Step-by-step
4 oz = 1/4 pound.
1 casserole requires 1/4 pound
28 casseroles require x
1/28 = 1/4 // x For ease change 1/4 to a decimal
1/28 = 0.25 / x Cross multiply
1*x = 28 * 0.25
x = 7
We need 7 pounds of cheese to make 28 dishes.

which of the following explains why 2/3(x+3)=2/3(x-6)has no solution
Answer:
D. The coefficients are the same, and the constants are different
Step-by-step explanation:
This means that because we have the same coefficient (2/3), if we wanted the same equation, the constants (x +/- #) would have to be the same, and since they are not in this instance, that makes the equation false, and therefore has no solution
A(-5, -4) → A' is a glide reflection where the translation is (x, y) → (x + 6, y), and the line of reflection is y = 3. What are the coordinates of A'?
A. (1, -4)
B. (-5, 2)
C. (1, 10)
D. (11, 2)
Answer:
(1, -4)
Step-by-step explanation:
(-5,-4) -> (x,y) so x = -5 and y = -4. Apply the rule (x+6,y) to that point by substituting in your x and y values.
(-5+6,-4) = (1, -4)
The function f(x) = mx + 5 is its own inverse. Find the value of m?
mx + 5 = (x - 5) / m
mx + 5 = x/m - 5/mAnswer:
Step-by-step explanation:
first find the inverse equation
y = mx + 5
y - 5 = mx
(y - 5) / m = x
(x - 5) / m = f⁻ˣ(x)
The original function is a line with slope m and y intercept of 5
The inverse function is a line with a slope 1/m and x intercept of 5
so the common line is where m = 1/m
m = 1/m
m² = 1
m = ± 1
The only line with a common slope between these two options is when
m = -1 and y intercept is 5
