Answer: 6

Step-by-step explanation:

To get 3/4 miles to 1 mile we must take the reciprocal of the number and multiply it.

\frac{3}{4}×\frac{4}{3} =1

We need to multiply the 4 1/2 ounces by 4/3 too

4\frac{1}{2}×\frac{4}{3} =6

4 1/2 ounces per 3/4 miles

6 ounces per 1 mile

Answer:

<h3>6 ounces</h3>

Step-by-step explanation:

Let the unknown number be x

4 \frac{1}{2}  \:  \: ounces =  \frac{3}{4} \:  \: miles  \\ x = 1 \:  \: mile

Now simply use cross multiplication to solve it

4 \frac{1}{2}  \times 1 =  \frac{3}{4} x \\  \frac{9}{2}  \times 1 =  \frac{3}{4} x \\  \frac{9}{2}  =  \frac{3x}{4}  \\

Now make x as the Subject

\frac{9}{2}  =  \frac{3x}{4}  \\  \frac{9 \times 4}{2 \times 3}  = x \\  \frac{36}{6}  = x \\ 6 = x

<em>So</em><em> </em><em>the</em><em> </em><em>answer</em><em> </em><em>is</em>

<h2><em>6</em><em> </em><em>ounces</em></h2>

What is the solution to this equation?
Fantom [35]

Answer:

x=-17

Step-by-step explanation:

<em>Original</em><em> </em><em>Equation</em><em>;</em>

<em>x</em><em>+</em><em>1</em><em>2</em><em>=</em><em>-</em><em>5</em>

<em>The</em><em> </em><em>1</em><em>2</em><em> </em><em>will</em><em> </em><em>cross</em><em> </em><em>the</em><em> </em><em>equal</em><em> </em><em>sign </em><em>so</em><em> </em><em>it </em><em>will</em><em> </em><em>become</em><em> </em><em>-</em><em>1</em><em>2</em><em>. </em><em>So</em><em> </em><em>it's</em><em> </em><em>going </em><em>to</em><em> </em><em>be</em><em>;</em>

<em>x</em><em>=</em><em>-</em><em>5</em><em>-</em><em>1</em><em>2</em>

<em>There </em><em>are</em><em> </em><em>two negative </em><em>number</em><em> </em><em>so</em><em> </em><em>you </em><em>add</em><em> </em><em>them</em><em> </em><em>and</em><em> </em><em>when</em><em> </em><em>you </em><em>add</em><em> </em><em>them</em><em> </em><em>it</em><em> </em><em>would</em><em> </em><em>still</em><em> </em><em>be</em><em> </em><em>negative</em><em>.</em><em> </em><em>And</em><em> </em><em>you </em><em>would</em><em> </em><em>have </em><em>to</em><em> </em><em>add</em><em> </em><em>them </em><em>because </em><em>when</em><em> </em><em>there </em><em>are</em><em> </em><em>two</em><em> </em><em>negative</em><em> </em><em>numbers</em><em> </em><em>without </em><em>any</em><em> </em><em>other</em><em> </em><em>sign </em><em>you </em><em>will</em><em> </em><em>have </em><em>to </em><em>add</em><em> </em><em>so</em><em> </em><em>it's </em><em>going</em><em> </em><em>to </em><em>be</em><em>;</em>

<em>x</em><em>=</em><em>-</em><em>1</em><em>7</em>

<em>This </em><em>is </em><em>the </em><em>final</em><em> </em><em>answer</em><em>!</em><em>!</em><em>!</em>

What is the answer to -3+p=?
nata0808 [166]
There is not an answer to an expression. 

-3+p is an expression, unless there was an equal sign and a sum at the end, that is when we can solve for the variable x. 

-3+p simply equals -3+p
