A wise man once said, "300 reduced by 3
times my age is 84." What is his age?
A) 72 B) 48
C) 68 D) 61
Answer:

Step-by-step explanation:
Let the man's age be x
300 - 3x = 84
300 - 84 = 3x
216 = 3x
x = 216/3
x = 72
Answer:
A

What percentage
of total hours was
spent jogging?
if you find the total hours for each sport i’ll give u brainlistttt paleeease
Answer:
40%
Step-by-step explanation:
So I mostly will focus on the jogging total hours because thats literally what it says lol. Anyways, here I used the percent equation, which is
___ is ___% of ___. Since the question is "what percent", we mark our blank percent part as x, and when I fill the equation in it will seem like this:
"20 is x% of 50 (total hours)". So, now I translate, and this means:
20=x50, or in other words, 20=50x. To get x alone we divide by 50, but we also do it for the 20. 20/50 is .4, but because it has to be a percent, we move the decimal 2 places to the right, which gives 40, and finally it becomes
40%.
Hope it helps
Answer:
40%
Step-by-step explanation:
(20 hours Jogging)/(50 hours Total) = 0.4
0.4 * 100 = 40

BRAINLIST!!! The area of Alex's room is 168 square feet. If his room is a rectangle and one side is 12 feet, how long is the other side.
Write an equation to find the missing length of Alex's room. Let x = missing length in feet
Solve to find the missing length of Alex's room
Answer:
the missing length is 14 feet.
Step-by-step explanation:
a = L × W
168ft² = 12 × W - divide both sides of the equation by 12
- 168 ÷ 12 = 14
168ft² = 12 × 14

Answer:
y = -5/2x +4
Step-by-step explanation:
First, make the equation into standard form.
5x + 2y = -10
2y = -5x - 10
y = -2.5x - 5
In order for two lines to be parallel, they must have the same slope. (In y = mx + b, "m" is the slope)
The slope in y = -2.5x - 5 is -2.5, so we need to find an equation with a slope of -2.5 (or -5/2)
In y = -2/5x - 8, the slope is -2/5
In y = 2/5x + 7, the slope is 2/5
In y = 5/2x - 6, the slope is 5/2
In y = -5/2x +4, the slope is -5/2.
Thus, y = -5/2x +4 is the right answer

The expression |-2-(-3) can be used to find the difference between point A and which other point?
A. Point B
B. Point C
C. Point D
D. Point E
Answer:
C. Point D
Step-by-step explanation:
Distance between two points
Given two points A(x,y) and B(w,z), the distance between them is:
[tex]d=\sqrt{(z-y)^2+(w-x)^2}[/tex]
If both points have the same y-coordinate (y=z), then
[tex]d = |w - x|[/tex]
Point A has coordinates (-2,3). Point D has coordinates (-3,3). The distance between them is
[tex]d = | -2 - (-3) |[/tex]
Thus the correct choice is
C. Point D
