Step-by-step explanation:
475 x 6 = 2850
There are 52 weeks in a year, so 52 x 2850 = 148,200
let
d1 = 250 mi the distance that Mattie Evans drove
v1 = the speed of Mattie Evans
d2 = 1300 mi the distance the plane traveled
v2 = the speed of the plane
The speed of the plane was 190 mph faster than the speed of the car:
v2 = v1 + 190
since time = distance/speed and they both traveled the same time we have
d1/v1 = d2/v2
250/v1 = 1300/v2 cross multiply
250v2 = 1300v1 divid eboth sides by 50
5v2 = 26v1
by solving the system of equations:
v2 = v1 + 190
5v2 = 26v1
we find
v1 = 45.24 mph
v2 = 235.24 mph
Answer:
Step-by-step explanation:
Yes, her estimate is not good because one hat is $14.50 and 2 binders are$3.20*2=^$6.40. Those two items combined is over $20. The pencils will put the total further over $20.
Pencils are $0.30 each. So 10 pencils will cost $3.
$5 - $3 = $2
The remaining $2 is enough for 6 more pencils.
So she could buy 10+6 = 16 pencils with $5.
