Answer:
All expressions are correct
Step-by-step explanation:
9z+7z = 16 z
We need to find an expression ( or expressions ) that are equal to 16z
6z+3z+ 7z = 16z Correct
z+8z+7z = 16z Correct
z*16 = 16z Correct
21z+ -5z = 16z Correct
Answer:
40 min is the answer
Step-by-step explanation:
To solve this we need to convert all the units into SI units
for ritu,
speed= 90km/hr
= 90 × 1km/ 1hour
= 90×1000/3600 m/s
= 25m/s
distance = 120×1000m
time = distance/ speed
= 120000/25
= 4800sec
= 4800/60min
= 80 min
for garima,
distance =120×1000m
speed = 60km/hr
= 60×1000/3600 m/s
=100/6 m/
time = 120000/(100÷6)
= 7200sec
= 7200÷60 min
= 120 min
time difference is 120-80 = 40 min
So, parallel lines have the same slope, therefore a parallel line to 2x+12, will have the same slope as that one, so which is it?

so, we're really looking for the equation of a line whose slope is 2, and runs through -1,1.
Answer:
P = 10w
Step-by-step explanation:
Number of point per correct spelling = 10
Number of words spelt correctly = w
Total points, p
P = (number of points per correct spelling * number of words spelt correctly)
P = 10 * w
P = 10w
Answer:
Step-by-step explanation:
(290 ft - 125 ft)/(3 hours) = (165 ft)/(3 hours) = 55 ft/hour
