Answer:
- (6-u)/(2+u)
- 8/(u+2) -1
- -u/(u+2) +6/(u+2)
Step-by-step explanation:
There are a few ways you can write the equivalent of this.
1) Distribute the minus sign. The starting numerator is -(u-6). After you distribute the minus sign, you get -u+6. You can leave it like that, so that your equivalent form is ...
(-u+6)/(u+2)
Or, you can rearrange the terms so the leading coefficient is positive:
(6 -u)/(u +2)
__
2) You can perform the division and express the result as a quotient and a remainder. Once again, you can choose to make the leading coefficient positive or not.
-(u -6)/(u +2) = (-(u +2)-8)/(u +2) = -(u+2)/(u+2) +8/(u+2) = -1 + 8/(u+2)
or
8/(u+2) -1
Of course, anywhere along the chain of equal signs the expressions are equivalent.
__
3) You can separate the numerator terms, expressing each over the denominator:
(-u +6)/(u+2) = -u/(u+2) +6/(u+2)
__
4) You can also multiply numerator and denominator by some constant, say 3:
-(3u -18)/(3u +6)
You could do the same thing with a variable, as long as you restrict the variable to be non-zero. Or, you could use a non-zero expression, such as 1+x^2:
(1+x^2)(6 -u)/((1+x^2)(u+2))
You add of the sides to get the perimeter.. 9 plus 9 is 18 and 5 plus 5 is 10. 10 plus 18 of 28. The perimeter of ABCD is 28.
I hope this helps.

Step-by-step explanation:
Answer:
7x + 3y </=8
Step-by-step explanation:
Let x represent the number of rides Beth rides and y represent the number of exhibits she views
Each ride costs $7 to ride and each exhibit costs $3 to view
This means that x rides will cost x × 7 = $7x
Also, if she views y exhibits, the cost will be y × 3 = $3y.
Total cost of x rides and y views will be 7x + 3y
if she has at most $98 to spend at the fair, it means that all she can spend must be lesser than or equal to $98
The required expression will be
7x + 3y </=8
Answer:
3/171
Step-by-step explanation:
The problem can be simplified into finding probability that Anna and Becky select 12 or 24 or 36 which are less than 40 and multiples of 3 and 4.
Probability of Anna selecting 12 = 1/9
Probability of Becky selecting 12 = 1/19
Probability of Anna and Becky selecting 12 = 1/9 * 1/19 = 1/171
Probability of Anna and Becky selecting 12 or 24 or 36 = 3* 1/171 = 3/171
