I think your answer is D because when you solve for K by simplifying both sides of the equation you get k>-10 so D would be your answer
Answer:
74.5%
Step-by-step explanation:
The total number of people sampled is 1000 people.
There are 745 people who where corrective lenses.
Percent is (part)/(whole); in this case, the part is 745 and the whole is 1000, so:
745/1000 = 74.5%
Thus, the answer is 74.5%.
Hope this helps!
Answer:
x=4, y=1
Step-by-step explanation:
We can solve this set of equations using elimination.
Multiply the first equation by 3:
Multiply the second equation by 5:
Now we take
Therefore, .
To solve for x, substitute y=1 into the second equation.
Hence, .
It will take them 5 weeks. Because Drew gets $8 a week and spends 3 so 8-3=5. And Jan gets $10 a week and spends 4 so 10-4=6. Then i add 5+6=11. Then I divide total $55/$11 which equals to 5 weeks. Hopefully i helped :)
