We are to solve this for x:   <span>1.8-3.7x=-4.2x+0.3

Combine like terms.  First, add 4.2x to both sides.  This results in 1.8+0.5x = 0.3, and then 0.5x = 0.3-1.8.

Next, 0.05x = -1.5, or 5x = -150, and x = -30. 

Must check this result by substitution of -30 for x in the original equation.

Is  </span><span>1.8-3.7(-30)=-4.2(-30)+0.3 true or false?</span>

Answer:

The answer is 3

Step-by-step explanation:

add -4.2 to -3.7 to get 0.5, then subtract 1.8 by 0.3 to get 1.5 on the other side. then you divide 1.5 by 0.5 to get 3. Hope this helps and have a good day!:)

Answer:

JL = 78

Step-by-step explanation:

MN is a midsegment. Based on the midsegment theorem,

MN = ½(JL)

MN = 5x - 16

JL = 4x + 34

Plug in the value

5x - 16 = ½(4x + 34)

5x - 16 = ½*4x + ½*34

5x - 16 = 2x + 17

Collect like terms

5x - 2x = 16 + 17

3x = 33

Divide both sides by 3

x = 11

✔️JL = 4x + 34

Plug in the value of x

JL = 4(11) + 34

JL = 44 + 34

JL = 78
