Answer:
Each one can take 7 lessons.
Step-by-step explanation:
Dylan and Dusty plan to take weekly surfing lessons together.
They want to spend $100 each on new surfboards = $100 × 2
= $200
They want to spent total amount for lessons and surfboards is at most $480.
After spending on two new surfboards the money left with
= 480 - 200
= $280
The charges for 2-hours classes for surfing lessons = $20 per person
The charges for 1 hour classes for them = $20.00
With $280 they will be able to take maximum number of lessons
=
= 14 lessons
Each one can take 14/2 = 7 lessons.

2(x + 4) =
x + 4 which is the second option is the equivalent expression.
Explanation:
First, we need to calculate the value of two-fifths of x. It means 2 portions out of the five portions of x which equates to x.
Now we calculate the values of the two expresssions on the LHS.
1) 2 (two-fifths x + 2) = 2 (x + 2) =
x + 4.
2) (two-fifths x + 4) = 2(x + 4) =
x + 8.
Now we determine values of the four expressions on the RHS.
1) Two and two-fifths x + 1 = 2x + 1
2) Four-fifths x + 4 = x + 4
3) Four-fifths x + 2 = x + 2
4) Two and two-fifths x + 8 = 2x + 8.
Out of the various LHS and RHS values, the LHS value and
RHS value is the same. So option 2 is the answer.
Answer:
x =
Step-by-step explanation:
(subtract from both sides)
