Distribute
y+10+c=z
minus y from both sides
10+c=z-y
minus 10 both sides
c=z-y-10
Answer:
O equivalent by the associative property of addition
Step-by-step explanation:
Associative Property = a property of some binary operations, which means that rearranging the parentheses in an expression will not change the result
Which means that you can change the expression 25x - (6x+12) without changing the answer. So, the changed result would be (25x-6x) + 12.
Find the distance between points A-2; 3, B2; 1:
d = √<span>(<span>xb</span> - <span>xa</span>)2 + (<span>yb</span> - <span>ya</span>)2</span> =
= √<span>(2 - (-2))2 + (1 - 3)2</span> =
= √<span>42 + (-2)2</span> = √16 + 4 =
<span>= <span>√20</span><span><span> </span></span></span>
Answer:
no
Step-by-step explanation:
4x + 15 = 6x + -11
Reorder the terms:
15 + 4x = 6x + -11
Reorder the terms:
15 + 4x = -11 + 6x
Solving
15 + 4x = -11 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation.
15 + 4x + -6x = -11 + 6x + -6x
Combine like terms: 4x + -6x = -2x
15 + -2x = -11 + 6x + -6x
Combine like terms: 6x + -6x = 0
15 + -2x = -11 + 0
15 + -2x = -11
Add '-15' to each side of the equation.
15 + -15 + -2x = -11 + -15
Combine like terms: 15 + -15 = 0
0 + -2x = -11 + -15
-2x = -11 + -15
Combine like terms: -11 + -15 = -26
-2x = -26
Divide each side by '-2'.
x = 13
Simplifying
x = 13
