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
Answer:
18,480
Step-by-step explanation:
3/4 = 0.75
1/2 = 0.5
Area = l * w
100.75 * 75.5 = 7,606.625
Answer = 7,606.625 ft
Answer:
$147
Step-by-step explanation:
so to find 20% I usually divide the original cost by 100 to get 1% then multiply that number by 20.
in this case 122.50/100= 1.225, 1.225x20 = 24.5
24.5 + 122.50 = 147
