Assume the girls sold X boxes in the first week. They sold in the second week X+5 and 2X+10 in the third week.
The sum X + X + 5 + 2X + 10 = 431
4X = 416. Therefore X = 104
The answers are:
a0 = 104
a1 = 109
a2 = 218
Hope that helps you :)
Answer:
the area is 30
Step-by-step explanation:
area of triangle =base×height
so ,
base=7.5
height=4
why , shouldn't we take 5(or)6 as height because we shouldn't take slanting lengths as height.
so apply base and height in the formula
7.5×4=30
please follow me
(132 min)/(12 mi) = (t)/(66 mi)
t = (66 mi)*(132 min)/(12 mi) = 726 min
It will take the bicyclist 726 minutes to travel 66 miles.
