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>.
That's what the graph should look like and I wrote the rest on there just incase you needed any other information.
Find common denominators ...12 then subtract
Answer:
8(4m + 1) --> 32m + 8
5(5 + x) --> 25 + 5x
Step-by-step explanation:
8(4m + 1)
8 x 4m = 32m
8 x 1 = 8
32m + 8
5(5 + x)
5 x 5 = 25
5(x) = 5x
25 + 5x
So,
Finding problems such as "x is 10% of y" and solving them is really easy: simply multiply the number you are given by 10 to get 100% of that number.
3.3 * 10 = 33
The number you are looking for is 33.
