Commutative property of addition is
a+(b+c)=(a+b)+c

so just move the partenthsees ()

(1 5/8+4 3/4)+3 2/8=1 5/8+(4 3/4+3 2/8)

$(1 \frac{5}{8}+4 \frac{3}{4})+3 \frac{2}{8} = \\ \\
( \frac{13}{8}+ ^{2)}\frac{19}{4})+\frac{26}{8}= \\ \\
 \frac{13+38}{8}+ \frac{13}{8}= \\ \\
 \frac{64}{8}= \boxed{8}$

What is the missing value of 5x-2y=30 (8,)

AnnZ [28]

Answer:

In this equation, we can start by understanding that "x" has a value of 8, as given in the ordered pair. When multiplied by 5, this leads to "40 - 2y = 30". Next, we can subtract 40 from both sides of the equation. This leads us to a value of "-2y = -10". The next step would be to divide both sides by -2 as a way of isolating "y", which leads us to a final value of "y = 5". The final ordered pair would be (8,5).

How do I use the subtraction theorem to write equivalent expressions?

Andreas93 [3]

The subtraction theorem states that for all real numbers, $a$ and $b$ , $a-b=a+(-b)$ .
(To subtract, we can add the inverse.)
Thus, we can have the these two equivalent expressions.

$3 - 2 = 3 + (-2) = 1\\ \\ 5 - (-2) = 5 + 2 = 7$
