Answer:
that would be 1/4x
Step-by-step explanation:
Answer:
1. 39 km/hr
2. $235
3. 16
4. 7m+3 inches
Step-by-step explanation:
1. Original speed of car: x km
x+21=60
x=39
original speed: 39 km/hr
2. Amount that the freshman class raised: x
2x+85=555
2x=555-85=470
x=235
Amount that the freshman class raised: $235
3. Number: x
5x-9=71
5x=71+9=80
x=16
The number: 16
4.
3m+5+4m-2
= 3m+4m+5-2
=7m+3 inches
A perpendicular line would have a slope that is the negative reciprocal of the slope you are given. Therefore the slope of the new line would be -4/1 or just -4.
You can now use point-slope formula and plug in your numbers to figure out the equation of that line.
Point-Slope form: y-y1=m(x-x1)
Therefore your equation would be: y-5=-4(x-5)
Answer:
Step-by-step explanation:
1 km = 0.621 mi
1 hr = 60 min
(5 km)/(4.5 hr) × (0.621 mi)/km × (1 hr)/(60 min) = (0.0115 mi)/min
