4a + 5 = 3(a - 7) + 2a
4a + 5 = 3a - 21 + 2a
4a + 5 = 5a -21
4a -5a = -21 -5
-a = -26
a = 26
Answer:
9h² + 51h + 28
Step-by-step explanation:
(5h + 4)(4h + 7)
=> 9h² + 35h + 16h + 28
=> 9h² + 51h + 28
Therefore, 9h² + 51h + 28 is the simplified expression.
Hoped this helped.
Answer:
A = $13,660.81
Step-by-step explanation:
P (principal) = $4,800.00
I (interest) = $8,860.81
First, convert R as a percent to r as a decimal
r = R/100
r = 6.2/100
r = 0.062 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 4,800.00(1 + 0.062/4)(4)(17)
A = 4,800.00(1 + 0.0155)(68)
A = $13,660.81
Your pay is described by a piecewise function p(t) where t is hours worked.

The domain of this function is the number of hours you can work in a week—zero to 168. The range is the set of values p(t) can take on, which we have said is p(0) to p(168). This problem, however, is asking for the range for a typical 40-hour week. That will be p(0) to p(40):
the interval [0, 280].
Answer:
The relationship ⇒ <u>25x + 40y = 12,250</u>
Step-by-step explanation:
The number of student memberships = x
The number of adult memberships = y
The monthly membership fee for a student = $25
The monthly membership fee for an adult = $40
The total fee = 25x + 40y
Al's Athletic Club receives $12,250 in membership fees for the month of January.
So, the relationship between x and y is:
<u>25x + 40y = 12,250</u>
