Tom is 6 1/6 feet tall and Gloria is 5 1/2 feet tall. Find the difference in their heights
Answer: 2/3 feet
Step-by-step explanation:
6 1/6 - 5 1/2
6 1/6 - 5 3/6
5 7/6 - 5 3/6 = 4/6 or 2/3

I need the value of X
Answer:
x=30
Step-by-step explanation:
So we know its a supplementary angle which is angles athat add up to 180 degrees since its a straight line.
Make an equation: 60+60+2x=180COmbine like terms
120+2x=180
subtract 120 on both sides
2x=60
x=30

A student thinks that the regular pentagon in the diagram
has 10 lines of symmetry. Explain the student's error.
Answer:
A
Step-by-step explanation:
The student must have thought that every single arrowhead is a line of symmetry, so since there are 10 arrowheads, there must be 10 lines of symmetry. This is incorrect because if you look closely at the diagram, each line has 2 arrowheads, so the student is overcounting by a factor of 2. They should have just counted the number of lines, not arrowheads. Therefore, there must be 10/2 = 5 lines of symmetry, not 10. Hope this helps!

Since babysitting and working at the grocery store are two different things, you would need two different variables.
So x and y would be the correct representation.

Answer:f(x) in order from left to right= -20, 5, 10, 15, 30 i.) -.06 ii.)-40
Step-by-step explanation: f(x) is the answer of 5 times whatever x is, so when it’s telling you what x is all you have to is multiply it by the number next to x which in this case is 5. after doing that you get the answers above. for i.) it’s telling you the answer which is -3, so you divide that by 5 getting -.06. In ii.) it gives you x which is -8 so you plug that in giving you -40.
