To answer this, we need to know the formula of the relationship between the work and the power rating and time.
The formula is:
E(J)<span> = </span>P(W) ×<span> t</span><span>(s)
</span>360000 = 200 * t
t = 360000 / 200
t = 1800 s
So, Emily will spend 1800 seconds in vacuuming. It is also equivalent to 30 minutes.
-x + y = -13 → -3x + 3y = -39
-4x + 3y = -51 → -4x + 3y = -51
x = 12
-x + y = -13
-(12) + y = -13
-12 + y = -13
+ 12 + 12
y = -1
(x, y) = (12, -1)
Answer:
18
Step-by-step explanation:
half of 36 is 18
so you would have an improper fraction and then turn it into 2
Answer:
Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.
