Answer:18.375
Step-by-step explanation:8x/7+9=30
We simplify the equation to the form, which is simple to understand
8x/7+9=30
Simplifying:
+1.14285714286x+9=30
We move all terms containing x to the left and all other terms to the right.
+1.14285714286x=+30-9
We simplify left and right side of the equation.
+1.14285714286x=+21
We divide both sides of the equation by 1.14285714286 to get x.
x=18.375
Brainliest please :)
I did another one just like this about an hour ago. I did it the elegant, tedious way,
and it took about 2 feet of screen. Then I realized there was a totally bourgeois but
easy way to do it. For 5 points, I'll give you the method for the masses:
List all the possible pairs of digits that add up to 9, along with their flips:
18 . . . . . 81
27 . . . . . 72
36 . . . . . 63
45 . . . . . 54
Do you see any pair that are different by 27 ?
How about 36 and 63 ?
So the original number is 63, and when you flip it, it becomes 36, which is 27 less.
Lets say N as cells
On monday N = 3
Multiply means that on tuesday is 9 cells and
Wednesday will 27 cells
Therefore N on wednesday is
No. of cells = 9n
