You still want at most 

(15x) + (22y) ≤ 100(-z)           (equation used)

0 ≤ z ≤ 10                              (amount you want to leave unspent)

y ≥ 1                                     (amount of dress shirt you need)

This is your system of equation, in which the numbers must fulfill both equations

hope this helps

Solve the following:<br> A) 4x-1/2=x+7<br> B) 3x+2=2x+13/3<br> C) 2x-7/4=3+x/3
s2008m [1.1K]

Answer:

a. 2.5  

b. 2.333

c. 2.85

Step-by-step explanation:

A) 1. subtract -x on both sides              2. to get 3x-1/2=7  

3. Add 1/2 on both sides                    4. to get 3x=7.5    

5. divide 3 on both sides                   6. To get... x=2.5

B)1. Same process.                               2. x+2=13/3        

3. x=13/3-2                                         4. x= 2.33(repeating)

C) 1. same process.                           2. 2x-x/3=3+7/4

3. 2x-x/3=4.75                                  4. Isolate -x/3  

5.-x/3=4.75-2x                                    6. multiply both sides by 3          

7. -x=14.25-6x                                      8. 5x=14.25

9. x= 2.85

* remember to distribute the 3 to each variable.

Question 3 of 18
iren [92.7K]

Answer:

D. 0.74.

Step-by-step explanation:

It is a BINOMIAL trial, which means that there are only two outcomes: either success, or failure.

So, if the probability of success is 0.26, the probability of failure will be 1 - 0.26 = 0.74.

Hope this helps!
