Answer:
1) 37
2) 23
3) x = 4
4) 58
Step-by-step explanation:
1) 15 + 22 = 37
2) 54 - 31 = 23
3) 6x + 1 + x + 7 = 36
7x + 8 = 36
7x = 28
x = 4
4) 3x + 10 + 47 = 9x - 39
57 = 6x -39
96 = 6x
16 = x
3(16) + 10 = 58
Answer:
see below
Step-by-step explanation:
22 15
1. L -----------------M------------N LN = 22 + 15 LN = 37
31 ??
2. L -----------------M------------N MN = 54 - 31 MN = 23
|<-----------54 ---------------->|
6X+1 X+7
3. R -----------------S------------T find X
(6x + 1) + (x + 7) = 0
7x = -8
x = - 8/7
47 3X+10
4. D -----------E---------------------F find EF
|<--------- 9X - 39 ------------>|
47 + (3x + 10) = (9x - 39)
3x - 9x = -39 - 10 -47
-6x = -96
x = -96 / -6
x = 16
EF = 3x + 10
EF = 3(16) + 10
EF = 58
