Answer:
This shape is a rectangle so that means that the angles are 90°. From sum of angles of a triangle, x + 3x + 10 + 90 = 180 which means 4x + 100 = 180 → 4x = 80 → x = 20°.
12+ 36x = 36x +12
Thai your answer
Bob is x yrs old
Sister is x+6 yrs old
X+X+6=32
2X+6=32
2X=32-6
2X=26
2X/2=26/2
X=13
Bob is 13 yrs old
Sister is 13+6 yrs
= 19 yrs
13yrs+19yrs = 32 yrs
Now its 100% accurate
Answer:
Fraction of money spent on calculator = 2/5

------------------------------------------------------------------------------------------------
To find the fraction of saving:
Fraction of money saved = 1 - calculator - book
Fraction of money saved = 1 - 2/5 - 12/35 = 9/35
Fraction of the money saved = 9/35
Step-by-step explanation:
Answer: 50%
Step-by-step explanation:
There are 2 sides to a coin. If you divide 100 by 2, you get 50%. A 6-sided die has 6 sides. If you divided 100 by 6, you get 16.6666666667%. Since there are only 3 even numbers on a 6-sided die, you would multiply 3 by 16.6666666667% to get 50%. So, the probability you will flip a heads and roll an even number is a 50% chance.
