The three items cost altogether is : 111.32 + 28.75 + 73.21 = 213.28
So, he must work 213.28 : 8.75 = 24.3748571429...
Since if he works 24 hours, he wouldn't have enough money to buy the 3 items, so he must work 24 + 1 = 25 hours.
Recheck : 25 x 8.75 = 218.75 ( > 213.28)
6+75t-16r2
h(t)=0+75+0
solution: h’(t)= 75

Step-by-step explanation:
Although I didn't get your question but I think you want to right intersection or union
PΠQ is equal to {5,6}
P union Q{3,4,5,6,}
Answer:
Let's solve your system by substitution.
x+y=−5;2x+2y=−5
Step: Solvex+y=−5for x:
x+y=−5
x+y+−y=−5+−y(Add -y to both sides)
x=−y−5
Step: Substitute−y−5forxin2x+2y=−5:
2x+2y=−5
2(−y−5)+2y=−5
−10=−5(Simplify both sides of the equation)
−10+10=−5+10(Add 10 to both sides)
0=5
