Answer:
512
Step-by-step explanation:
So we need to isolate the variable. In order to do that, we need to multiply both sides by 5/4.
Why? That's so that 4/5z will be canceled out when multiplied by 5/4 to get just z.
And so, we would get 20 as our answer.
Y=12x+30
I think this is correct. But please don't hold me to it:) Hope I helped!
30x-18 because 6•5x=30x and 6•3=18.
Answer:
<u>The correct answer is A. Divide both sides by positive 5</u>
Step-by-step explanation:
Let's solve the equation for finding z and the necessary steps to do it:
5z - 3 = 12
5z = 12 + 3 (Adding 3 at the right side and subtracting 3 at the left side)
5z = 15 (Adding 12 plus 3 at the right side)
5z/5 = 15/5 (Dividing by positive 5 at both sides)
<u>z = 3</u>
<u>The correct answer is A. Divide both sides by positive 5</u>
