3x + 15 - 9 = 2(x +2)
3x + 6 = 2(x +2)
3x + 6 = 2x + 4
3x + 6 - 2x = 2x - 2x + 4
x + 6 = 4
x + 6 -6 = 4 - 6
x = -2
Answer:

Step-by-step explanation:
The radius of the circle is 7 cm.
The two legs of the triangles are 7cm as well.
Area of a trinagle is ( base × height )/2.

Multiply the value by 2 since there are two triangles.

Calculate the area of the circle.

The radius is given.

Take
as 


Subtract the area of the two triangles from the area of the whole circle.

The area of the shaded part is 105 cm². The total area of the shape is 154cm².

Answer:
The checkbook balance is $178 .7.
Step-by-step explanation:
As given
Sherry had an ending balance $ 125.36, outstanding deposits of $153.53, and outstanding checks of $100.19.
Thus
Checkbook balance = Ending balance + Outstanding deposits - Outstanding checks
Putting the values in the above
Checkbook balance = $ 125.36 + $153.53 - $100.19
= $ 278.89 - $100.19
= $ 178.7
Therefore the checkbook balance is $178 .7.

true
Step-by-step explanation:
#'s 9-14
Base info: 40% are red, 30% are white, 20% are blue, and 10% are green
9) 40% chance to get red, 10% chance to get green. 50% chance to get one of either.
10) getting red: 40%
Getting blue: 20%
11) 80% (100% - 20% = 80%)
1/8 = 12.5%
12) 12.5% chance
13) 25% chance
14) 12.5 x 5 = 62.5
62.5% chance
