Answer: 2.5
Step-by-step explanation:
y = rx
substitute numbers in and solve for r
if
y = 10
x = 4
then
10 = r4
r = 10/4 = 2.5
this works for all the other numbers and always gives r = 2.5
Answer: 5.75
<u>Order the numbers</u>
Before: 4,10,2,6,8,9,1,6
After: 1, 2, 4, 6, 6, 8, 9, 10
<u>Add</u>
1+2+4+6+6+8+9+10=46
<u>Divide</u>
46÷8=5.75
We can solve this problem in different ways:
0. Statement: As angle 1 and 3 are vertical angles, and angle 1, 5, 4 form a straigth angle, so angle 2 and (algle 4 + angle 5) are vertcal angles too.
Reason:
