Hello!
To solve algebraic equations, we need to use SADMEP. SADMEP is an acronym used only solve for x in algebraic equations. SADMEP is expanded to be: subtraction, addition, division, multiplication, exponents, and parentheses.
(a) 4 + 2(-1) = 10 + 2 (multiply)
4 + -2 = 10 + 2 (add)
2 = 12
This equation has no solutions because <u>2 is never equal to 12</u>.
(b) 30 = 10 - (6 + 10) (simplify the parentheses)
30 = 10 + -1(16) (multiply)
30 = 10 - 16 (simplify)
30 = -6
This equation has no solutions because<u> 30 and -6 is never equal to each other</u>.
(c) 8x = 4x + 4x + 10(x - x)
8x = 4x + 4x + 10(x - x) (simplify [add and subtract])
8x = 8x + 10(0) (multiply)
8x = 8x
This equation has an infinite number of solutions because if you <u>substitute any value into the original equation</u>, <u>both sides of the equation</u> will be <u>always equal</u>.
7 1/2 / 6 = 1.25 pounds
Candy weight in each box = 1 1/4 pounds
Answer:
$39
Step-by-step explanation:
$62 = t - $22 + $60 - $15
t = $39
Answer:
The answer is 125. X= 125 solve it and you get x=125. Have a great day
Step-by-step explanation:
Answer:y=2x+1
I believe. I could be wrong. But I think im right
Step-by-step explanation:
2x-y=-1
-2x -2x
(-1)-y=-1-2x(-1)
y=2x+1
