Answer:
x = 5
Step-by-step explanation:
32/4 = 8
40/8 = x
x = 5
You just need to see if you can isolate the y-variable.
10. b - 16.6 = -3.7.....add 16.6 to both sides
b - 16.6 + 16.6 = -3.7 + 16.6
b = -3.7 + 16.6
b = 12.9
14. 18.91 = -7.9 + x.....add 7.9 to both sides
18.91 + 7.9 = -7.9 + 7.9 + x
26.81 = x
16. 295.8997 = -10.1k....divide both sides by -10.1
295.8997 / -10.1 = (-10.1/-10.1)k
- 29.297 = k
18. -94.4724 = 3.3x....divide both sides by 3.3
- 94.4724 / 3.3 = (3.3 / 3.3)x
- 28.628 = x
20. -29.4x = -148.764...divide both sides by -29.4
(-29.4 / -29.4)x = - 148.764 / -29.4
x = 5.06
Answer:
17.8
Step-by-step explanation:
9.5x = 3.25(52)
9.5x = 169
x = 169/9.5
x = 17.8
