Answer:

Step-by-step explanation:
Suppose the electrician spends t hours at the house working.
Amount charged for every house call by electrician = $50
The electrician earned a total of $400 for a 5 hour job.
Also, C denotes total cost of the electrician's services.
So, the equation for C in terms of t is given below.

Here, 
The coefficient of x in the equation is 1/(300 grams). Multiply by the reciprocal of that, which is (300 grams).
x = (300 grams)×(2 grams)/(100 grams) = (300×2/100) grams = 6 grams
_____
This is the way you solve any equation where x is multiplied by some value in the only term on one side of the equal sign.

Answer:
7 steps.
Step-by-step explanation:
Since the monkey is sitting on the first step already you can subtract 9 by 1 to find the amount of steps left.
9-1 = 8 steps left
The monkey jumps 3 steps down
8-3= 5 steps
Then jumps 2 steps up
5 + 2 = 7 steps
The monkey has 7 more steps until he reaches the water level.
