The statement is true because he used distributive property and in the second step -3x-12+2x=2x-12-3x is equal in both sides. So this means that if this is in a graph it would be 1 line instead of 2 which means that there are many solutions of this was on a graph.

What is the answer to -3/4 (2)(-6) in fraction form

nasty-shy [4]

I'm assuming the question looks like this?

$\frac{-3}{4} (2)(-6)$

If so then the answer should be:

$\frac{-3}{4} (2)(-6)=\frac{-3}{4} (-12)=9$

Hope this helps!

5. You are making your weekly mean plans and are working with the following constraints: It costs $8 to go out to dinner. It cos

Goshia [24]

Let

x-------> the number of dinner

y-------> the number of lunch

we know that

$8x+5y \leq 42$ -------> equation A

$x=y$ ------> equation B

Substitute equation B in equation A

$8[y]+5y \leq 42$

$13y \leq 42$

$y \leq 42/13$

$y \leq 3.23$

so

the greatest number of lunch is $y=3$

$x=y$

Hence

the greatest number of dinner is $x=3$

therefore

the greatest number of meals is

$x+y=3+3=6$

<u>the answer is</u>

$6$

the inequality |t-57|<7 describes the range of monthly average temperature, T, in Degrees Fahrenheit, for san Francisco, Cali

Y_Kistochka [10]

<u>Solution</u> is: $50\leq T\leq 64$ and it means, the minimum temperature is 50° Fahrenheit and the maximum temperature is 64° Fahrenheit.

<u><em>Explanation</em></u>

Given inequality is: $|T-57|\leq 7$

As this is absolute inequality, so we will get two different inequalities-- one for positive and another for negative. So.....

$T-57\leq 7\\ \\ T\leq 7+57\\ \\ T\leq 64$

and

$-(T-57)\leq 7\\ \\ -T+57\leq 7\\ \\ -T\leq 7-57\\ \\ -T\leq -50\\ \\ T\geq 50$

So, the final combined solution will be: $50\leq T\leq 64$

<em>It means that the minimum temperature for San Francisco, California is 50° Fahrenheit and the maximum temperature is 64° Fahrenheit.</em>
