Answer:
12
Step-by-step explanation:
my boys said so, and I agree
(7*60)/34
Vertical angles are equal
5x - 40 = 3x + 8
5x - 3x = 8 + 40
2x = 48
x = 48/2
x = 24
m∠ABC = 3x + 8 = 3 * 24 + 8 = 80°
(or m∠ABC = 5x - 40 = 5 * 24 - 40 = 80°)
Answer:
x= -1
Step-by-step explanation:
4x+3=x
we subtract x to both sides of the equation:
4x -x +3 = x-x
we have:
3x +3 = 0
we subtract 3 to both sides of the equation:
3x +3 -3 = -3
3x = -3
we divide by 3 both sides of the equation
3x/3 = -3/3
x= -1
we test the result in the original equation:
4x+3=x
4*(-1) + 3 = -1
-4 +3 = -1
-1 = -1
so finally x= -1

Answer:
Whole integers
Step-by-step explanation:
0, 1, 2, 3, 4, 5... are all whole numbers, or the counting numbers. If we didn't specify "whole", then that would also include decimals, and we don't count usually with decimals.
Hope this helps!
