Answer:
450 per month
Step-by-step explanation:
5000-1400=3600
3600/8=450
Since Peter already has 1400 dollars saved you can subtract that form the total amount and since he is trying to get the rest in eight months you just divide the difference by eight.
Answer:
12 * 2 + x * 2 = 54
x = 15
x is 15
Step-by-step explanation:
12 * 2 + x * 2 = 54
24 + x * 2 = 54
-24 -24
x * 2 = 30
/2 /2
x = 15
Answer:
138
Step-by-step explanation:
There is 60 seconds in a minute, so if the heart beats 23 times in 10 seconds, it is 138 bpm.
23 * 6 = 138
Answer:
307 Meters
Step-by-step explanation:
Answer:
y-2 = 1/4(x-20) point slope form
y = 1/4x -3 slope intercept form
Step-by-step explanation:
y = -4x
The slope is -4
The slope that is perpendicular is the negative reciprocal
- (1/-4) = 1/4
The slope of our new line is 1/4
We have a point and the slope, so we can use point slope form
y-y1 = m(x-x1)
y-2 = 1/4(x-20)
If we want the line in slope intercept form, distribute
y-2 = 1/4x -5
Add 2 to each side
y-2+2 = 1/4x -5+2
y = 1/4x -3
