Answer:
Step-by-step explanation:
-x - 21 = 5x
Add 'x' to both sides
-x -21 +x = 5x + x
-21 = 6x
6x = -21
x = -21/6
= -7/2
x = -3.5
We know, Point slope form is written as:
y - y₁ = m(x - x₁)
First, We need to Calculate the slope:
m = (y₂ - y₁) / (x₂ - x₁)
m = (2 - 1) / (-3-2)
m = 1/-5
m = -1/5
Take any one of them: Let's take (-3, 2) as our coordinate:
y - 2 = m(x - (-3))
y - 2 = -1/5(x + 3)
In short, Your Answer would be Option D
Hope this helps!
So he started at
9:30 a.m.
three hours and ten minutes later
9+3 is 12
30 + 10 is 40
12:40 p.m.
it took him 47 minutes to replace
so 12:40 plus 47 minutes is
1:27 p.m.
He then rode for another 56 minutes to finish the race
so 1:27 plus 56 minutes
2:23 p.m.
Hope this helps :)
Answer:
.5357
Step-by-step explanation:
Follow PEMDAS
Multiplication (M) comes before division (D)
Therefore, solve the multiplication expressions first:
2 * 3 * 5 = 30
and
7 * 8 = 56
Now Division:
30 / 56 = .5357
Percent literally means per one hundred so you can say:
420(55/100)
23100/100
231
You could also think of it like setting up equal ratios...
55/100=n/420
n=23100/100
n=231
