Annie has a lemonade stand and her mom pays her 5 dollars every week for her to go get her supplies. Her dad pays her ten dollars one week. She has 35 dollars that month. How many weeks did Annie’s mom pay her?
35 - 10 = 25
25 divided by 5 equals 5.
To check: 5 x 5 equals 25 plus 10 equals 35
The sum of internal angles of a triangle is 180°, so:
3x+2x+50+x+46=180
6x=84
x=14
angle a = 3*14=42
angle b = 2*14+50=78
angle c = 14+46=60
25,200 hours
112x12=1,344
212x112=23,744
1,344+23,744+112=25,200
