10+ 10+10=30
5 x 9 = 45
30 + 45 = 75 cents
Okay,
So we know how many pizzas they sold throughout the week, we add those together.
93
67
78
44
<u> 123</u>
405
You divide "405" by the amount of numbers there are.
so "5" into "405"
5 goes into 40 8 times
now we have 5 into 5 which goes 1 time.
Our answer is a solid 81.
To check our work, we can multiply 81 by 5.
5*1=5
5*8=40
405.
A. 81 is your answer
All 3 angles of a triangle must equal to 180. You can simply set up an equation to solve this and set it equal to 180.
Angle 1 - 50 + x
Angle 2 - x
Angle 3 - 2x -10
50+x+x+2x-10=180
4x+40=180
4x=140
x=35
Angle 1 = 50+35= 85
Angle 2 = 35
Angle 3 = 2(35) - 10 = 60
60+35+85=180
