Y=x+4
3x+Y=-8
3x+x+4=-8
X=-3. Substitute the value of x
Y=-3+4
Y=1
(X,Y)= (-3,1)
So the answer is C
This is a division problem.
0.9/6 = 0.15
Answer: 0.15 of a pizza
Okay. To find the upper quartile, first, line the numbers up in order. It would be this: 5, 7, 8, 10, 11, 13, 14, 18, 27. Then, we need to find the median. Cross the numbers out from furthest left to farthest right. When you do this, your median is 11. Now, ignore the median to find the quartile and repeat the same steps. You ignore the median whenever you have to solve for the quartiles. However, you’ll have to add the two numbers up and divide by 2 to find the quartiles in this case. 7 + 8 is 15. 15/2 = 7.5. The lower quartile is 7.5, but we’re looking for the upper quartile. Do the steps I said before to find it. 14 + 18 is 32. 32/2 is 16. There is your answer. The upper quartile is 16.
Answer:
24X58-9=1,383
800x24=19,200
Step-by-step explanation:
24x58=(24x8)+(24x50)
24x8=160+32=192
24x50=200+1,000=1,200
192+1,200=1,392-9=1,383
800x24=3,200+16,000=19,200
