Answer:
A and C
Step-by-step explanation:
Just plug in the point into the equations:
a) 14 = 2(4.5) + 5
14 = 9 + 5 14 = 14 A is correct
b) 14 = 3(4.5) + 1.5
14 = 13.5 + 1.5 14 ≠ 15 B is not correct
c) 14 = 4(4.5) - 4
14 = 18 - 4 14 = 14 C is correct
d) is not correct 12 is already to large and 10 is not a negative so it is far to large
This one could be 8/10, or 4/5 simplified
Answer:
C
Step-by-step explanation:
2.2-2.5
Since a + and a - make a minus if we have 2.2+(-2.5) we would get 2.2-2.5. So C is the anwser.
51÷12= 4.25
just remember when your wondering how many times a number goes into something, divide the something by the number
