Answer:
He bought 17 books.
Step-by-step explanation:
Given that:
Total money spent = $89
Cost of each book = $5
Shipping price = $4
We have to find, Total number of books
So if the number of books be represented by b, the equation will become:
Cost of one book * total number of books + shipping price = total money
Putting values we get:
5*b + 4 = $89
By simplifying:
5*b = 89 - 4
5*b = 85
Dividing both sides by 5 we get:
b = 17
So the total number of books bought is 17.

V = l w h <span>V = s3</span>
V = (5 mm)(5 mm)(5 mm) V = (5 mm)3
<span>V = 125 mm3</span> <span>V = 125 mm<span>3</span></span>
Answer =3/10
Adding all the frequency... 13+6+9+12=40
And we looking probability of picking yellow... Hence... Yellow /total =12/40
Hence giving 3/10
Answer:
a
Step-by-step explanation:
because the sums of the lengths of any two sides of a triangle must be greater than the length of the third side
Let x person in 1 van and y persons in 1 bus
so for school A took 2x+2y=106
for school B took 8x+y=151
make a system

solve it:
multiply second equation by 2
<span> 2*8x+2*y=2*151</span>
16x+2y=302
second equation minus first we have:
16x+2y-2x-2y=302-106
14x=196
x=14 - persons in 1 van
to find y put x=14 in equation:
2x+2y=106
2*14+2y=106
2y=106-28
2y=78
y=39
Answer: 1 van can carry 14persons, 1 bus can carry 39 persons
