Answer:
C is the answer
Step-by-step explanation:
28/20 in simplest form is: 7/5
70/50 in simplest form is 5/7
Because,
28/20 divided by 2 is 14/10, divided by 2 again is: 7/5
70/50 divided by 2 is 25/35, divided by 2 again is: 5/7
Problem 7 is choice B, which is the entire number line shaded in but the value -4 has a hole at this location to mean "exclude this point from the solution set". So basically x can be any number but -4.
Problem 8 is choice C. You have a closed circle (or filled in hole) at -1.5 on the number line. Then you shade to the left of the closed circle to indicate the set of values that are smaller than this endpoint. So n can be -1.5 or it can be smaller than -1.5 (something like -2 or -3, etc).
Answer:
6.12
Step-by-step explanation:
tan 27≈0.51
Know that tan=
0.51=
Multiply 12 on both sides
6.12=x
