Evaluate. 25/5+7-(4x3)

1 answer:

7 0

Using PEMDAS, we know that we must solve what’s in the perentheses first so: 25/5 + 7 - (4x3) = 25/5 + 7-12. Next, we simplify 25/5 because that is division so now it is 5+7-12. Now you add 7 to 5 to get 12 and then subtract 12 so your answer is now zero.

Is x+3=-5y in standard form?

skad [1K]

Answer:

Nope

Step-by-step explanation:

Standard form for a linear equation in two variables is $Ax+By=C$ with the terms containing x and y on the left side of the equation and a number on the right side.

$x+3=-5y$

Subtract 3 from both sides.

$x=-5y-3$

Add 5y.

$x+5y=-3$

Solve x + 3y = 9. 3x – 3y = –13

Sloan [31]

$Question \ 1) \ x + 3y = 9$

$
x=9-3y
 
$ $|Subtract \ 3y \ from \ both \ sides|$

$Question \ 2) \ 3x - 3y = -13$

$
3(x-y)=-13
 
$ $|Factor \ out \ the \ common \ term \ 3|$

$x-y= \dfrac{13}{3}$ $|Divide \ both \ sides \ by \ 3|$

$x=- \dfrac{13}{3}+y$ $|Add \ y \ to \ both \ sides|$

$x=y- \dfrac{13}{3}$ $|Regroup \ terms|$
