The mistake is “there are”
Answer:
2=1/4(4+b)
Step-by-step explanation:
(0,1), (4,2)
first, find the slope
slope formula- (y2-y1)/(x2-x1)
plug in the coordinates
(2-1)/(4-0)
subtract
1/4
slope=1/4
slope intercept form- y=mx+b
choose one of the coordinates to plug in
(4,2)
plug it in
2=1/4(4+b)
Answer:
25 grams
Step-by-step explanation:
If there were 4 pieces eaten, and 3/7 left, then there must have been 7 pices altogether and 3 are left.
Remark
They are travelling in opposite directions. Their distances will be added until that distance = 462 miles.
You need only add the r*t values together. You do not need to find the distance.
Givens
d = 462 miles
r1 = 115 mph
r2 = 95 mph
t = the time each was traveling.
Formula
r1 * t + r2*t = d
Substitute and solve
95 * t + 115 * t = 462 Add the like terms on the left.
210 * t = 462 Divide by 210
t = 462 / 210
t = 2.2 hours.
t = 2 1/5 hours
t = 2 hours and 12 minutes
All three answers are the same.
