Answer:
631139.04 kilometers in 3 years
Step-by-step explanation:
Let x = how many kilometers she walk
y = time (minutes)
Since she walks 4km in 10 minutes.
x = 4, y = 10
(4,10)
But how many minutes if she walk only a kilometer? Divide x and y by 4.
(1,2.5)
She walks a kilometer under 2.5 minutes.
Now finding rate of changes.
Since m = 2.5
and of course, the function should be proportional so the equation should be y = mx.
Since time should be minutes instead of years.
Since 3 years = 1577847.6 minutes
Divide both sides by 2.5
The greatest common factor is 8
Answer: 3
Step-by-step explanation:
25 x (5 - 2) ➗ 5 - 12
Applying the rule of BODMAS
- Solve task in bracket first
25 x (5 - 2) ➗ 5 - 12
= 25 x (3) ➗ 5 - 12
= 75 ➗ 5 - 12
- Solve task of division next
75 ➗ 5 - 12
= 15 - 12
= 3
Thus, the answer is 3
Answer:
$50.40
Step-by-step explanation:
Make an equation:
20%
------ = -------
63 100%
- 63 x 20= 1,260
- 1,260/100=12.6
- 63 - 12.6 = 50.40
Answer:
m= 6-(-4)/-4-0 = -5/2
m=-5/2, the slope.
Step-by-step explanation:
Use the formula m=y2-y1/x2-x1
To find the SLOPE (m) you need to do m=y2-y1/x2-x1
(0,-4) is ordered pair #1, (-4,6) is ordered pair #2
m = 6-(-4)/-4-0
m = -5/2, THE SLOPE.
