Answer:
1 7/18
Step-by-step explanation:
5/6 / (12/20)
5/6 * 20/12
The answer is A.
Add all the number values together and then divide it by the number of values you have: 43+32+65+88+50+72=350
350/6=58.33
The power of 25 on the variable z needs to be changed. It has to be divisible by 3.
Answer: 27=3y
Let’s focus on the wording here.
Is= is in a math equation usually refers to equals. When a number is something, it equals something.
Times= Times in math refers to multiplication. When you times a number by something else, you multiply it.
Now knowing this, let’s substitute these symbols into the equation
27 is 3 times a number y
27=3•y
When with a variable, 3•y will usually just be left 3y. Let’s change this now.
27=3•y
27=3y
This is your final equation! Hope this helps comment below for more questions :)
