Ответ:
x=4
Step-by-step explanation:
Distribute the 2 -> 2(4x−11)+9=19 -> 8x-22+9=22
Combine Like Terms -> 8x-13=19
Add 13 to Both Sides -> 8x=32
Divide Both Sides by 8 -> x=4
Ответ:
1. (6 x 5) + (14 x 8) = 142
142/20 = 7.1
2. (8 x 6) + (12 x 9) = 156
156/20 = 7.8
3. (86 x .8) + (93 x .2) = 87.4
4. (0.1 x 0.85) + (0.4 x 0.7) + (0.5 x 0.75) = 74%
5. (8 x 0.5) + (5 x 0.2) + (8 x 0.3) = 7.4
Sorry this took so long!
