Answer:
p=2
Step-by-step explanation:
-7p = -3p - 8
Add 3p to each side
-7p+3p = -3p+3p - 8
-4p = -8
Divide each side by -4
-4p/-4 = -8/-4
p = 2
Answer:

Step-by-step explanation:
0.02564 hours per dollar, or 1/39 hours per dollar
Answer:
Step-by-step explanation:
It's a proportion rather than an equation that you might be more accustomed to.
2/0.05 = x/ 0.95 Cross multiply
2 * 0.95 = x * 0.05 Divide by 0.05
2 * 0.95/0.05 = x
x = 38 grams of sugar should be added to the 2 grams of cinnamon.
There's another way to do it.
2/0.05 = (x + 2)/1 Cross multiply
2*1 = 0.05x + 0.1 Subtract 0.1 from both sides
1.9 = 0.05x
1.9/0.05 = x
x = 38
Which ever way you understand better is the answer. 100 / 100% is 1
For f(x) plug in the number given into the x value of the equation. As an example A would be
f(-6) = 1 - 5 (-6)
Simplify: f(-6) = 1 - (-30)
Solve: f(-6) = 31
