Hey there, 

Lets solve this together, my friend

Divide both sides by <span>−2 

</span>c=10/-2 

Simplify <span>10 /−2</span> to <span>−<span>10 / 2 

</span></span>c = -10 / 2 

Simplify 10 / 2 to <span>5 

</span>c=-5&#10;&#10; &#10; 
<span>
-------- Check your work  

</span>&#10;-2c=10&#10; &#10; 

Let <span>c=−5 
</span>
-2*-5=10&#10;&#10; &#10; 

Simplify <span><span>2×−5</span></span><span> to </span><span><span>−10 

</span></span>10=10 
<span><span>
Therefore, the answer is correct!</span></span>

-2c=10
Dividing both sides by -2
c=\frac{10}{-2}
c=-5

I need help with this<br> If x + 3 /3 = y + 2/ 2 ,then x/ 3 =
abruzzese [7]

Answer:

First solve for x

then substitute

Step-by-step explanation:

\frac{x+3}{3}= \frac{y+2}{2}

6(\frac{x+3}{3}=\frac{y+2}{2})

2x + 6 = 3y + 6

2x = 3y

x = \frac{3y}{2}

If \frac{x+3}{3}= \frac{y+2}{2} then \frac{x}{3} =

x = \frac{3y}{2} /3 = \frac{y}3}

<h2>Given,</h2>

11x - 16 = -49

=> 11x = - 49 + 16

=> 11x = -33

=  > x =  \frac{ - 33}{11}

<em><u>=</u></em><em><u>></u></em><em><u> </u></em><em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>-3</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>

____ [38]

Answer: 32 apples

Step-by-step explanation:

The ratio of apples to oranges sold is given as 4 to 2. Since Tia wants to sell a total of 48 apples and oranges, the number of apples that she should sell would be:

= 4/(4+2) × 48

= 4/6 × 48

= 32

Therefore, he should sell 32 apples.

Factor 3/4 out of 3/4z + 6
Alenkasestr [34]
ANSWER

\frac{3}{4} z + 6 =  \frac{3}{4} (z +  8  )


EXPLANATION

We want to factor
\frac{3}{4}
out of

\frac{3}{4} z + 6

The first term is already having a factor of
\frac{3}{4}
The constant term which is the second term is not having a factor of
\frac{3}{4}
so we need to use a trick of multiplying and dividing by the same factor to obtain,



\frac{3}{4} z + 6 =  \frac{3}{4} z +  \frac{3}{4}  \times  \frac{6}{ \frac{3}{4} }


We can now factor
\frac{3}{4}
out of the right hand side to obtain,

\frac{3}{4} z + 6 =  \frac{3}{4} (z +  \frac{6}{ \frac{3}{4} } )
Let us rewrite the right most fraction using the normal division symbol.

\frac{3}{4} z + 6 =  \frac{3}{4} (z +  6 \div  \frac{3}{4}  )




We simplify to obtain,

\frac{3}{4} z + 6 =  \frac{3}{4} (z +  6  \times  \frac{4}{3}  )



This further gives us,


\frac{3}{4} z + 6 =  \frac{3}{4} (z +  2 \times  4  )



\frac{3}{4} z + 6 =  \frac{3}{4} (z +  8  )
