What should I pick ? Joe measured a brick using a ruler with centimeters and got 9 cm. He then measured the same brick using a ruler with millimeters and got 90 mm. Are these measurements equivalent? Why or why not?

A. Yes, because 10 cm is the same as 1 mm.
B. Yes, because 1 cm is the same as 10 mm.
C. No, because 2 cm is not the same as 20 mm.
D. No, because 1 cm is not the same as 1 mm.

B

Step-by-step explanation:

because 1 cm is the same as 10mm

for this case we have the following expression:

to solve, we rewrite the expression as:

we apply double c and we have:

thus, the quotient is 48.

so, patel found a wrong ratio and the multiplication was incorrect.

option d

c

step-by-step explanation:

it would be see because your formula is f(x)=6x, so 6 times 1 is 6 and you go on and the best answer is c.
