Answer:

option 4

Step-by-step explanation:

\frac{2}{3} (\frac{1}{4} x - 2) = \frac{1}{5} (\frac{4}{3} x - 1) ← distribute parenthesis on both sides

\frac{1}{6} x - \frac{4}{3} = \frac{4}{15} x - \frac{1}{5}

Multiply through by 30, the LCM of 6, 3, 15, 5

5x - 40 = 8x - 6 ( subtract 8x from both sides )

- 3x - 40 = - 6 ( add 40 to both sides )

- 3x = 34 ( divide both sides by - 3 )

x = - \frac{34}{3} = - 11.333..

Answer:

4) -11.3...

Step-by-step explanation:

distribute both sides to get (1/6)x - (4/3) = (4/15)x - (1/5)

move the variables to one side and the constants to the other: ((4/15) - (1/6))x = (-(4/3) + (1/5))

simplify to get (1/10)x = (-17/15) multiply everything by 10 to get x=-34/3 or -11.33333333333333333...

A contractor needs to buy nails to build a house. The nails come in small boxes and large boxes. Each small box has 150 nails an
forsale [732]

The system 150x+400y=1950 and x = y+2 could be used to determine the number of small boxes and large boxes ordered where x represents the number of small boxes and y represent the number of large boxes.

Step-by-step explanation:

Given,

Number of nails in small box = 150 nails

Number of nails in large box = 400 nails

Total nails in ordered boxes = 1950 nails

Let,

x be the number of small boxes ordered.

y be the number of large boxes ordered.

According to given statement;

150x+400y=1950          Eqn 1

The contractor bought 2 more small boxes than large boxes

x = y+2                           Eqn 2

The system 150x+400y=1950 and x = y+2 could be used to determine the number of small boxes and large boxes ordered where x represents the number of small boxes and y represent the number of large boxes.

Greg stands at a horizontal distance 35 feet from the base of the building. The angle of elevation Craig stands out a horizontal
ValentinkaMS [17]
Because X is opposite of the 38° angle and 35 is adjacent to the 38° angle, you would use tan. To set up the equation you would put X over 35 and set an equal to 38(tan). Then you would multiply both sides by 35 to cancel out the 35 on the bottom of the X. When you multiply 38(tan) by 35, you get X equals 27.
