Jim was thinking of a number. Jim doubles it, then adds 19 to get an answer of 70.1. What was the original number?

Answer:

25.55

Step-by-step explanation:

Let us take the number he thinked of be x .

On doubling it :-

→ N = 2x

On adding 19 :-

→ N = 2x + 19

According to Question :-

→ 2x + 19 = 70.1

→ 2x = 70.1 - 19

→ 2x = 51.1

→ x = 51.1/2

→ x = 25.55

<h3>Hence the required answer is 25.55</h3>

Answer: Choice C

The first inequality is $124+121+x \ge 400$

The second inequality is $x \ge 155$

Replace x with whatever letter your teacher is using

=========================================================

Let x be the number of cans collected on week 3

Add this to the previous totals (for weeks 1 and 2) to get 124 + 121 + x. I'm going to leave this as is and not simplify. This is so the answer matches up. This total must be greater than or equal to 400, meaning 124+121+x can be 400 or larger.

124+121+x >= 400

245+x >= 400 .... combine like terms

x >= 400-245 .... subtract 245 from both sides

x >= 155

So you need to collect at least 155 cans for the third week so that you'll have at least 400 cans total.

The community needs 400,000 gallons of clean

Crank

Answer:

Yes

Step-by-step explanation:

10 million per day and we need to do 400,000 gallons of clean water per hour so we do 400,000 x 24, which ewual 9,600,000. So the answer 9,600,000 means 9,600,000 gallons of water per day and thats what the community needs, but we can do 10 million gallons per day, so the answer is yes. Our budget exceeds the amount of gallong needed per day.
