Answer:
5/12
Step-by-step explanation:
Assuming the each number is equally likely
1,2,3,4,5,6,7,8,9,10,11,12
There are 12 numbers on the spinner
Number less than or equal to 5: 1,2,3,4,5
There are 5 choices
P ( # < = 5) = Number less than or equal to 5/ total
=5/12
A. 125
the sum of the remote angles is equal to the exterior angle
90+35=125
1/4 of the times
because there are 4 sections, that means that there is a 1/4 probability.
1 = No 2 = Yes 3 = 1.88
2x+58+x=180 180-58=3x 122=3x
x=40.666
*the sum of the angles of the triangle is 180 degrees
The equation is true.
Simplify. Combine like terms:
3x + 15 = (2x + x) + (10 + 5)
3x + 15 = (3x) + 15
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 3x and 15 from both sides:
3x (-3x) + 15 (-15) = 3x (-3x) + 15 (-15)
3x - 3x = 15 - 15
0 = 0
~ True. The two expressions are equal to each other.
