Hi! :)
The answer is A, here's why:
When tipping at a restaurant, first you need to figure out how much you're tipping. You need to move the decimal left 2 places on how much you tip. So for 20%, you get .20
Then to figure out how much to tip for 20%, you would multiply that .20 by how much the bill was and that's your tip. So .20*30=6. Your tip should be 6 dollars, and the formula for that is t=.20<em>b</em>
Answer:
-1/5
Step-by-step explanation:
3/5 is greater than 2/5, so your answer goes into the negatives
Answer:
One equation would be y= -1.5x +11
Step-by-step explanation:
Here's a table to show the coordinates
x: y:
8 -1
-------------------
-4 17
the x coor. 8 goes down by 12 to get to the next x coor. -4.
8-12= -4
the y coor. -1 goes up by 18 to get to the next y coor. 17.
-1+18= 17
therefore 18/-12 is -1.5 which can be your k in y=kx+b.
Check your answer.
-1.5*8= -12 but when you add 11, you get the y coor. -1
Do the same with the other x coor.
-4*-1.5= 6 + 11 =17
11 can be your b in the slope-intercept form equation.
One equation may be y = -1.5x +11
24 = 24 cents. 62 nickels= multiply that by 5. 55 dimes= multiply that by 10. 16 quarters= multiply that by 25. 19 x 50 add together all solutions.
No, a teaspoon is too small to measure the capacity of a milk carton. You would use a quart to measure the capacity of a gallon.
Hope this helps :)
