A) the equation accuretly models this scenario because Emanuel has a total of 48 cards. He bought some (X) and his aunt gave him 18. In order to find the number of cards he bought you set the number of cards he bought and the number of cards he got from his aunt equal to the number of cards he has.
B) 48= X + 18
Subtract 18 over
30=X
He bought 30 cards from the store.
48+ 30+18
Answer:
The answer is 3
Step-by-step explanation:
since all of the output numbers can be reached by adding 3
Since all sides are equal, it is an equilateral triangle. Therefore each angle equals 60°.
7x - 3 = 60
7x = 63
x = 9
Clue: The angle subtended at the centre of a circle is twice that subtended at its arc.
Nonlinear because y is squared
