Step-by-step explanation:
<u>Step 1: Define</u>
-6(t + 2) = 18
<u>Step 2: Solve for </u><em><u>t</u></em>
- [Distributive Property] Distribute -6: -6t - 12 = 18
- [Addition Property of Equality] Add 12 on both sides: -6t = 30
- [Division Property of Equality] Divide -6 on both sides: t = -5
Answer:
<h2><u><em>
11.11% (approx.)</em></u></h2>
Step-by-step explanation:
<u><em>Given,</em></u>
Cost Price (C.P.) of a car bought by Hassan = $1800
Selling Price (S.P.) of the car = $2000
<u><em>So,</em></u>
Profit earned by Hassan
= S.P. - C.P.
- <em>[On substituting their value]</em>
= $2000 - $1800
- <em>[On subtracting]</em>
= $200
<u><em>Therefore,</em></u>
The profit percentage is
= × 100
- <em>[On substituting their value]</em>
= × 100
- <em>[On simplifying]</em>
= × 100
- <em>[On dividing 100 by 9]</em>
= %
OR
= 11.11% (approx.)
<u><em>Hence,</em></u>
<u><em>Required percentage profit of Hassan is 11.11% (approx.)(Ans)</em></u>

Step-by-step explanation:
Answer:
P(rolling a 2) = 1/6
Step-by-step explanation:
A standard cube has 6 sides, numbered from 1 - 6.
You are solving for the:
P(rolling a 2).
There is only one side that is number 2, out of the 6 sides, so your answer is:
P(rolling a 2) = 1/6
