This is a multiplication equation. So to solve for y, we must divide.
6.3/0.9 = 7
y = 7
Answer:
Seven is not an irrational number
Step-by-step explanation:
There are 8 letters total and 1 is J
so 7/8 probability of not picking the J
Fraction: 7/8
decimal: 0.875
percentage: 87.5%
Step-by-step explanation:
"markup" contains "up". so, the price goes "up". this is actually increasing the price (e.g. by calculating the profit margin of selling an item on top of the cost of buying the item from the manufacturer).
"markdown" contains "down". so, the price goes "down". e.g. with discounts.
here we have a markup. it is 150%.
that means the price goes up by 150% compared to the original cost.
so, the computer game costs in the store
the original cost + 1.5× original costs
25 + 1.5×25 = 2.5×25 = $62.50
A negative sign under a square root means that the root is a not a real number.
A negative sign outside a square root means we can "cover it" and evaluate the square root.
When the sign is outside, you can do the root first, then apply the sign. Not so if the sign is inside.
Thus, √-49 is not real and -√64 = -8.
