Answer:
x = -9
Step-by-step explanation:
12 + 2x + 24 = 27 + x
(12 + 24) + 2x = 27 + x
36 + 2x = 27 + x
subtract 27 from both sides
36-27 + 2x = 27-27 + x
9 + 2x = x
subtract x from both sides
9 + x = 0
subtract 9 from both sides
x = -9
(the steps could've been faster but that shows the most work)
check:
12 + 2(-9) + 24 = 27 + (-9)
36 - 18 = 18
18 = 18
True!
so -9 is correct
Answer:
a. 2
b. 2(9+5) = 28
Step-by-step explanation:
18 = 3 × 3 × 2
or (3 power 2 × 2)
10=2×5
a . GCF = 2
b. factor out 2 out of both 10 and 18 which their sum is 28 and write every thing that is left in the prantheses .
Plug in the x+3 for y.
8x-x+3=12
7x=9
X=1.3
Then, y= -0.25
To solve for 
, we need to isolate it on one side of the equation.
Take the square root of both sides, making sure to use both positive and negative roots.
cannot be simplified, so we'll leave it as-is.
Add 
to both sides to fully isolate .
Expand the solution by making two solutions, one where is positive and one where it's negative.
Answer:
10
Step-by-step explanation:
d = 10
For:
(X1, Y1) = (13, 2)
(X2, Y2) = (7, 10)
Distance Equation Solution:
d=(7−13)2+(10−2)2−−−−−−−−−−−−−−−−−√
d=(−6)2+(8)2−−−−−−−−−−√
d=36+64−−−−−−√
d=1–√00
d=10
