Solve each equation.<br> 1. 25 - 3x = 40<br> 2. } (x – 10) = -4
nordsb [41]

Step-by-step explanation:

For no 1

<em>2</em><em>5</em><em> </em><em>-</em><em> </em><em>3x </em><em>=</em><em> </em><em>4</em><em>0</em><em> </em>

<em>-</em><em> </em><em>3x </em><em>=</em><em> </em><em>4</em><em>0</em><em> </em><em>-</em><em> </em><em>2</em><em>5</em><em> </em>

<em>-</em><em> </em><em>3x </em><em>=</em><em> </em><em>1</em><em>5</em><em> </em>

<em> </em><em>-</em><em> </em><em>x </em><em>=</em><em> </em><em>1</em><em>5</em><em> </em><em>/</em><em> </em><em>3</em>

<em>Therefore </em><em> </em><em>x </em><em>=</em><em> </em><em>-</em><em> </em><em>5</em><em> </em>

<em>Now </em><em>for </em><em>no. </em><em> </em><em>2</em>

<em>1</em><em>/</em><em>3</em><em> </em><em>(</em><em> </em><em>x </em><em>-</em><em> </em><em>1</em><em>0</em><em>)</em><em> </em><em>=</em><em> </em><em>-</em><em> </em><em>4</em><em> </em>

<em>(</em><em> </em><em>x </em><em>-</em><em> </em><em>1</em><em>0</em><em> </em><em>)</em><em> </em><em>=</em><em> </em><em>-</em><em> </em><em>1</em><em>2</em><em> </em>

<em>x </em><em>=</em><em> </em><em>-</em><em> </em><em>1</em><em>2</em><em> </em><em>+</em><em> </em><em>1</em><em>0</em>

<em>Therefore </em><em> </em><em>x </em><em>=</em><em> </em><em>-</em><em> </em><em>2</em><em> </em>

<em>Hope </em><em>it </em><em>will </em><em>help </em><em>:</em><em>)</em>

A hose is leaking water at a rate of 2 oz/h. How many cups of water will leak out after 2 weeks?
Over [174]

Answer:

84 cups of water will leak out after 2 weeks

Step-by-step explanation:

* Lets how many how to change oz to cup

- One cup contains 8 oz

- We can use the ratio to solve this problem

- A hose is leaking water at a rate of 2 oz/h

- We need to find how many cups of water will leak out after 2 weeks

∵ The rate of the water leak out is 2 oz/hr

∵ 1 cup contains 8 oz

∴ 1 oz = \frac{1}{8} cup

∴ 2 oz = 2 × \frac{1}{8} = \frac{2}{8} = \frac{1}{4} cup

∴ The rate of the water leak out = \frac{1}{4} cup/h

∵ 1 day = 24 hours

∵ 1 week = 7 days

∴ 1 week = 7 × 24 = 168 hours

∵ The number of hours in 1 week is 168

∴ The number of hours in 2 weeks = 168 × 2 = 336 hours

⇒    cups    :    hours

⇒      \frac{1}{4}         :   1

⇒     x         :    336

- By using cross multiplication

∴ x = 336 × \frac{1}{4}

∴ x = 84

- x represents the number of cups of water leak out

<em>84 cups of water will leak out after 2 weeks</em>
