Step-by-step explanation:
Answer: 16, 10, 64
Step-by-step explanation:
64/4=16, so the 3rd number is 4x the first.
16-6=10. 6 less than the first number.
16+10+64=90.
Step-by-step explanation:
4.5x-2.3=6.7 (add 2.3 so no number in the equation)
6.7+2.3 is 9
4.5x=9 (divide by 4.5 as it's 9 is divisible by 4.5
9/4.5 is 2
X=2
put it back into the equation
4.5*2 is 9
9-2.3 is 6.7
Therefore X=2
