Simplify: 2+5(x+3)- (2x-7)(x+2)

Mathematics

Ann [662]4 years ago

Answer:

Cross multiply the denominators

(2x+7)*2 < 5*(5x-3)

4x + 14 < 25x - 15

2. Take all the variables on left hand side and constants on the right hand side

4x - 25x < - 15 - 14

- 21x < - 29

3. Since both sides have negative signs in front of them, we can multiply both hand sides by -1.

(-1) * (- 21x) < (-1)*(-29)

21x > 29

Note that if you multiply an inequality sign by any negative number, it gets reversed.

4. Now take the 21 below the 29 as a denominator and divide it

X > 29/21

X > 1.38

Filbert makes $14 per hour. If he makes time and a half for overtime, how much will he make for working 63 hours?
Marina CMI [18]

Answer:

$1323.00

Step-by-step explanation:

A simple equation that can be used to figure this out is:

p*1.5*o=t

The variables mean:

p- hourly pay

o- hours worked overtime

t- total amount of money earned.

(Also, the 1.5 is always used to calculate overtime, no matter what job, unless otherwise specified, and as referred in the problem as "time and a half").

So, to finally work out this problem:

($14*1.5)*63=?

first, (14*1.5)= $21

($21*63)= $1323.
