Formula: Distance = rate * time
570 = (R+(R-18))*3
570 = (2R - 18)*3
190 = 2R-16
208 = 2R
R = 104
Eastbound Train: 86mph
Westbound Train: 104mph
Answer:
y=3x+17
Step-by-step explanation:
Slope formula y2-y1/x2-x1=m
y=3x+b
Find b (y-intercept), enter the given coordinates (-3, 8)
8=3(-3)+b
8=-9+b
b=17
y=3x+17
Hope this helps! Please mark brainliest :)
The regular price is 3.18.
50% off half the price, so you can either divide the regular price by 2 or multiply it by 0.50
3.18 / 2 = 1.59 ( 3.18 *0.50 = 1.59)
so the sale price is 1.59
now subtract the sale price from $5 to find the amount of change they got back:
5.00 - 1.59 = $3.14 change back
X is:
tan50 = 28 / x
1.19 = 28 / x
1.19 / 28 = x
x = 0.04

You can use the both formula
Unit rate mean 'how many per one'.
If you pay 10 dollars for 5 pears,
The unit rate would be 2 dollars per pear
