Ben bought 8 notebooks for $24.50. Some of the
notebooks were $2.50 each, and the others were
$3.25 each. If x represents the number of least
expensive notebooks, which equation can be used
to find the number of least expensive notebooks
purchased?
A. $5.75(8 - x) = $24.50
B. $2.50(x - 8) + $3.25x = $24.50
c. $2.50x + $3.25(8 - x) = $24.50
D. $2.50x + $3.25(x - 8) = $24.50

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
