Make your notebooks your y value and textbooks your x value. Then you can graph 40X + 2y = 440 or simplify and graph y = -20X +220

OK my paper says the numerical expression 5+12 represent the sum of 5 and 12. I don't understand

Afina-wow [57]

That literally means the numbers '5' and '12' written like this: 5 + 12

represent the sum of 5 and 12, which is the same as 5 + 12 (because the sum is when all the numbers are added up).

So it's saying 5 + 12 equals to 17.

Do you get it?

Needed help for my math please

Answer:

see explanation

Step-by-step explanation:

(a)

$\frac{a}{a}$ = 1 ( any value divided by itself = 1 )

(b)

$\frac{a}{1}$ = a ( any value divide by 1 is the value itself )

(c)

$\frac{a}{b}$ × $\frac{c}{d}$ = $\frac{ac}{bd}$

The product of 2 fractions is the product of the numerators divided by the product of the denominators

(d)

$\frac{a}{b}$ ÷ $\frac{c}{d}$ = $\frac{ad}{bc}$

To divide 2 fractions, leave the first fraction, change division to multiplication and turn the second fraction upside down, that is

$\frac{a}{b}$ ÷ $\frac{c}{d}$ = $\frac{a}{b}$ × $\frac{d}{c}$ = $\frac{ad}{bc}$

(e)

$\frac{a}{d}$ + $\frac{b}{d}$ = $\frac{a+b}{d}$

Since the fractions have a like denominator, add the numerators leaving the denominator. This applies to subtraction also

(f)

$\frac{a}{d}$ - $\frac{b}{d}$ = $\frac{a-b}{d}$
