Answer: x = 40
Step-by-step explanation:
these two angles are vertical angles, they will equal each other
therefore, move numbers and variables to the opposite sides of the = sign to isolate the X
3x-10 = 2x + 30
+10 +10 move the -10 by doing opposite
_____________
3x = 2x + 40
-2x -2x move -2x by doing opposite
____________
x = 40
you can check your work by substituting 40 in place of x
3(40) - 10 = 2(40) +30
120-10 = 80 + 30
110 = 110
answer is correct
Step-by-step explanation:
again, a line cutting through 2 parallel lines must have the exact same angles with both of them. otherwise they would not be parallel.
therefore, both angles must be identical
3x + 2 = 2x + 6
x = 4
The answer is 48/35 or 1 13/35 or 1.3714
Answer:
A x ≤ 17/2
Step-by-step explanation:
(2x+7) /-4 ≥ -6
Multiply each side by -4, remembering to flip the inequality
(2x+7) /-4 *-4 ≤ -6*-4
2x+7 ≤ 24
Subtract 7 from each side
2x+7-7 ≤ 24-7
2x ≤ 17
Divide each side by 2
2x/2 ≤ 17/2
x ≤ 17/2
Rewrite the equation below in standard form.
-3x+6y=12
C. -x+2y=4
if you take each term and divide them by 3 you will get the c
