The answer is A. To add fractions, the denominator has to be the same. What number do 9 and 3 share when multiplying ? It is 9.

So multiply 2/3 by 3/3 to get 6/9. And 1/9 by 1/1 to get 1/9. Now add 6/9 with 1/9 which is 7/9

Now add 7/9 with 5/18. 9 and 18 share 18. Multiply 7/9 by 2/2 which is 14/9. Add 14/9 to 5/18 which is 19/18

A school wants to put on a dance recital Middle School dancers have short programs that run 4 minutes long High School performer
sp2606 [1]

Answer:  The answer is \textup{M}+\textup{H}\leq 10~~\textup{and}4\textup{M}+7\textup{H}\leq 90.


Step-by-step explanation: Given that a school wants to put on a dance recital. The programs of Middle school dancer will be short of 4 minutes each and programmes of High school performers will be long of 7 minutes each.

Number of middle school dances is "M" and number od high school dances is "H".

Since there cannot be more than 10 dances all together, so fisrt inequality can be written as

\textup{M}+\textup{H}\leq 10.

Also, the entire recital must take maximum 90 minutes, so the second inequality can be written as

4\textup{M}+7\textup{H}\leq 90.

Thus, the pair of inequalities is

\textup{M}+\textup{H}\leq 10,\\\\4\textup{M}+7\textup{H}\leq 90.

the seventh and eighth grade bands held a joint concert. together there was 188 band members. if the eight grade band is 3 times
Montano1993 [528]
8th grade = 3x = 3(47) = 141 band members.

7th + 8th = 188

7th = x
8th = 3x

x + 3x = 188    ; x = 47 ;  47 + 3(47) = 47 + 141 = 188
4x = 188
4x / 4 = 188 / 4
x = 47 --> 7th grade

8th grade = 3x = 3(47) = 141

To check:
x + 3x = 188    ; x = 47 ;
47 + 3(47) = 188
47 + 141 = 188
188 = 188
