Take the three and divide it with the 12 which would get you 4 so put a open circle Above the 4 and make the line go to the left I think I hope this will help
Answer:
62.7° (1 d.p.)
Step-by-step explanation:
Please see attached picture for full solution.
We can create a system of equations with the information we know.
J = 4L
J + L - 6 = 64
The first equation is pretty self-explanatory. Jack is 4 times as old as Lucy. The second equation is just adding their ages together. We subtract 6 because the sum of their ages was 64 three years ago. Three years ago, both Jack and Lucy were 3 years younger (total of 6).
Substitute 4L in for J in the second equation and solve.
4L + L - 6 = 64
5L = 70
L = 14
If Lucy is 14, then Jack is 14*4 = 56.
Answer:
multiply 5×1,000 B multiply 5×10 three times and then add the products C move the decimal point in the number five, three place values to the left D move the decimal point in the number five, three place values to the right E move the digit 5, three place values by adding three zeroes to increase its value.
Let's write x as our age and our cost as y -
If x≤5 , y=0
If 5<x≤12, y=10
If 12<x≤18, y=25
If x>18, y=35
It should be pretty straightforward to graph from there, but please ask if you're having any issues!
