She would have to study about 48 hours to get a score of 97.
Hopefully that helped! :)
The group of tiles represent answer A. There are 6 x² tiles, 3 x tiles, and 1 tile.
For this problem, I'd use cross-multiplication.
9/12 = x/8.
When cross multiplying, multiply 12*x and 9*8. This leads to a new equation:
12x = 72.
Then you solve as an algebra problem.
*Divide 12 on both sides*
x = 6.
You scored 18 points in your fourth game because if you played 4 games and got 12 points each game that equals 48 points all together and if the average is 10 points for the first 3 games that equals 30 points for the three games so 48-30=18
Answer:
The missing number is 4
Step-by-step explanation:
Given
21 x 39 x _____ x 19 divided by 12 = 5187
Required
Fill in the gap
Let the missing number be represented with y; So, the expression becomes
Multiply both sides by 12
Rearrange the expression on the left hand side
Divide both sides by 15561
Hence, the missing number is 4
