<u>Answer</u>
3.5 hours.
<u>Explanation</u>
The first step is to calculate the constant of proportionality.
t ∝ 1/n
t = k/n Where t = time, K= constant and n = number of people
t = k/n
k =tn
= 5×7 = 35
The equation becomes;
t = 35/n
for n = 10,
t = 35/10
t = 3.5 hours.
Answer:
<h2>y = 0</h2>
Step-by-step explanation:
x + 3y = 28
Put x = 28 and solve for y:
28 + 3y = 28 <em>subtract 28 from both sides</em>
28 - 28 + 3y = 28 - 28
3y = 0 <em>divide both sides by 3</em>
3y : 3 = 0 : 3
y = 0
Answer:
200-20=180
Step-by-step explanation:
Well, is not a product, just a sum of three terms, so to simplify simply expand and combine them as constants,
3² + 3⁴ + 3⁷
9 + 81 + 2187
2277
Answer:
The remainder is the number that is left over after dividing. It is always less than the divisor. The remainder is an essential part of the answer and is shown in the quotient preceded by the letter R.
