Answer:
Ratio of Wood MS to Parker MS = 81 : 131
Step-by-step explanation:
Given
number of students at WMS = 136+188 = 324
number of students at PMS = 316+208 = 524
Ratio of students
WMS : PMS = 324 : 524 = 81 : 131
Answer:
y = 3x - 4
Step-by-step explanation:
Slope-intercept is defined <em>y = mx + b</em>
Where m = slope (change in y-coordinate/ change in x-coordinate)
and b = y-intercept (where the graph crosses the y-axis)
For every 1 unit the line moves horizontally... it travels 3 units vertically. Therefore the slope (m) equals 3/1 or 3
The line crosses the y-axis at -4. Therefore... the y-intercept (b) is -4
I hope this helps!
If the total age of both April and Amy are 53
And Amy is 9 years younger than april.
Then to solve for Amy's age you would subtract 9 from 53 and divide by 2
which equals 22
Since amy is 9 years younger than April, then April's age is Amy's age 22 + 9 which gives you 31
April's age is 31 and Amy's age is 22
Since you cannot add numbers which have x to the power of something and normal x, A and B are incorrect. C is also incorrect because I don't even know how you could get that number.
D is correct.
(14x2 + 7x) + 9x2 - you don't even need the brackets, so
14x2 + 7x + 9x2
(14x2 + 9x2) + 7x
23x2 + 7x
Answer:
Step-by-step explanation:
Given that in 10 minutes, the top 3 contestants of a hot dog eating contest consumed 136 hot dogs. The winner ate 9 more hot dogs than the runner-up, and the runner-up ate 8 more hot dogs than the third-place contestant.
Let winner up ate x hot dogs
Then runner up ate 9 less than the winner i.e. 
The third place contstant ate 8 less than runner up i.e.
Total ate by these three =
Winner ate 54, runner up ate 45 and third ate 37
