Answer:

see explanation

Step-by-step explanation:

17

The diagonals of a parallelogram bisect each other, then

x + 6 = 11 ( subtract 6 from both sides )

x = 5

and

y - 7 = 10 ( add 7 to both sides )

y = 17

(18)

The opposite sides of a parallelogram are congruent , then

3a + 11 = a + 15 ( subtract a from both sides )

2a + 11 = 15 ( subtract 11 from both sides )

2a = 4 ( divide both sides by 2 )

a = 2

and

3b + 5 = b + 11 ( subtract b from both sides )

2b + 5 = 11 ( subtract 5 from both sides )

2b = 6 ( divide both sides by 2 )

b = 3

abruzzese [7]

Answer:

  h = 13.333 +693.333/r

Step-by-step explanation:

For h hours, Brandee's pay will be ...

  pay = 40r +(h -40)(1.5r) . . . . 40 hours at rate r + overtime (h-40) hours at 1.5r

  pay = 40r +1.5hr -60r . . . . . eliminate parentheses

  pay = 1.5hr -20r . . . . . . . . . . collect terms

Solving for h, we have ...

  pay +20r = 1.5hr . . . . . . . . . . add 20r

  h = (pay +20r)/(1.5r) . . . . . . . . divide by 1.5r

For the given pay of 800 +240 = 1040, we have ...

  h = (1040 +20r)/(1.5r)

  h = 13.333 +693.333/r . . . . . simplify to 2 terms

_____

<em>Additional comments</em>

You need to know r to find the number of hours Brandee worked. She got paid $800 for a presumed 40-hours of regular time, so made r = $20 per hour. The above formula will tell you she worked 48 hours in the pay period.

kolezko [41]

Answer:

second option: 32.8 m, 48.2 m, 81.1 m  

Step-by-step explanation:

20.2 m + 20.4 m = 40.6 m.  which is bigger than 20.6 m. so yes  

32.8 m + 48.2 m = 81 m.  which is smaller than 81.1 m. so no  

12.8 m + 25.7 m = 38.5 m. which is bigger than 35.9 m. so yes  

35.6 m + 49.9 m = 85.5 m. which is bigger than 83.2 m. so yes
