Step-by-step explanation:
LM + MN = LN
x + 7 + 3x + 20 = 6x - 5
4x + 27 = 6x - 5
-4x -4x
27 = 2x - 5
+5 +5
32 = 2x
÷2 ÷2
16 = x
MN: 3x + 20
3(16) + 20
48 + 20
68

Answer: The length of the field is 98m. The width of the painting is 87cm
Step-by-step explanation: To find the length we must remember that the area formula is length x width so all we must do is divide the area by the width. To find the width of the painting you have to subtract the two length sides from the perimeter and then divide the number found by 2. 99x2= 198 372-198=174 174/2=87
48-10=x x=38
38x2= 76
so basically his weight is 48, which is ten more than his fathers weight, so you subtract ten from 48, giving you 38. 38 is only half the father's weight, so you double it and get 76.
