yKpoI14uk [10]

Answer:

  • 168 in 7 hours.

Step-by-step explanation:

<u>We can't multiply.</u>

<u>We got to count up by 12's for each 1/2 hour.</u>

12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168.

<u>Simplified:</u>

  • 24, 48, 72, 96, 120, 144, 168.

<u>Estimate:</u>

  • 12 = 1/2 hour
  • 24 = 1 hour
  • 36 = 1 1/2 hours
  • 48 = 2 hours
  • 60 = 2 1/2 hours
  • 72 = 3 hours
  • 84 = 3 1/2 hours
  • 96 = 4 hours
  • 108 = 4 1/2 hours
  • 120 = 5 hours.
  • 132 = 5 1/2 hours
  • 144 = 6 hours
  • 156 = 6 1/2 hours
  • 168 = 7 hours.

Answer is 168.

1. -222=-2x-3(4x+18)<br>2. 154=2x-6(-2x-14)<br>solve for x​
Aleksandr [31]

Answer:

1. x = 12

2. x = 5

Step-by-step explanation:

1. -222 = -2x - 12x - 54

-222 = -14x - 54

-168 = -14x

x = 12

2. 154 = 2x + 12x + 84

154 = 14x + 84

70 = 14x

x = 5

Find the values of x and y that makes each equation true. –(5y)i+12=4x+25i
vovikov84 [41]

Equate real part and imaginary part:

LHS:

real part -- 12

imaginary part -- 5y

RHS:

real part = 4x

imaginary part = 25

Equating::

12 = 4x

x = 12/4

x = 3

Again:

5y = 25

y = 25/5

y = 5

So,

x = 3

y = 5
