Mathematics

frez [133]3 years ago

Answer:

Write the equation as n + 31 = 113 and subtract 31 from both sides. The answer is 82.

Step-by-step explanation:

The sum of a number and 31 would be 'n + 31'. The sum equaling 113 would be '= 113'.

You would get 'n' by subtracting 31 for each side.

n+31 = 113\\n+31-31=113-31 \leftarrow \text{Subtraction Property of Equality} \\\boxed{n=82}

The statement: "Write the equation as n + 31 = 113 and subtract 31 from both sides. The answer is 82." should be the correct answer.

James, Priya, and Siobhan work in a grocery Store. James makes $9.00 per hour. Priya makes 40% more than James, and Siobhan make
wolverine [178]

Answer:

<em>* Siobhan's profit at the grocery store ⇒ $ 10.8 *</em>

Step-by-step explanation:

See below;

Priya's 40% profit in the grocery store ⇒ 40/100 * 9 = 2/5 * 9 = 18/5 ⇒ $ 3.6,

Priya's profit at the grocery store ⇒ 9 + 3.6 ⇒ $ 12.6,

Siobhan's 15% of Priya's profit from the store ⇒ 15/100 * 12.6 = $ 1.8

Siobhan's profit at the grocery store ⇒ 12.6 - 1.8 = $ 10.8

<em>* Siobhan's profit at the grocery store ⇒ $ 10.8 *</em>
