Answer:
30/54
Step-by-step explanation:
1st make and equation so 5/9=x/54
now cross-multiply.
5/9=x/54
(5)*(54)=x*(9)
270=9x
you can flip the equation.
9x=270 (next divide both sides by 9)
x=30
so 30/54=5/9
hope this helps :)
I don’t see a z anywhere in the equation but with the other numbers (I think) is -6.
Lunch starts at 1:30. So 1/4 of 1 hour is 15 minutes. Subtract 1 hour or 60 minutes from 1:30, which equals 12:30. So you have 1/4 remaining, so subtract 15 minutes from 12:30, giving you a final answer of 12:15.
Answer: 10
Step-by-step explanation: Remember that squaring a number is multiplying a number by itself. 100 = 10² because 10 x 10 = 100.
2x² + 5x - 3 = 0, 2) 3x² + 14x - 5 = 0, 3) (7 - 3x)(x + 2) = 4
