Answer:
the answer will be 2 cm
Step-by-step explanation:
As the difference between 1st and 2nd wheel's radius is 7 cm
16cm-9cm= 7cm
therefore the difference between the middle-wheel and smallest wheel also should be 7 cm, lets assume smallest wheel radius = x
9cm-x= 7cm
x=9-7
x= 2 cm
Answer:
8, 9, 10, 11, 12
Step-by-step explanation:
Consecutive integer problems are often easier to work if you consider average values. Here, the middle of the 5 consecutive integers is their average, which is 50/5 = 10.
This tells you the integer side lengths are 8, 9, <em>10</em>, 11, 12.
Let's try all the answers with the above equation
a) 4 as p and -4 as q
4 - 4 = 8? INCORRECT
b) 10 as p and 1 as q
10 - 1 = 8? INCORRECT
c) -4 as p and 4 as q
-4 - 4 = 8? INCORRECT
d) 11 as p and 3 as q
11 - 3 = 8? correct
