Mai biked 7 and 1/4 miles today, and Noah biked 3 5/8 miles. How many times the length of Noah's bike ride was Mai's bike ride?
Firdavs [7]

Answer:

2 times

Step-by-step explanation:

Mai biked 7\frac{1}{4} = \frac{29}{4} miles today and Noah biked 3\frac{5}{8} = \frac{29}{8} miles  today.

We are asked how many times the length of Noah's bike ride was Mai's bike ride.

Therefore, the length of Mai's bike ride was (\frac{29}{4} \div \frac{29}{8})  = 2 times the length of Noah's bike ride.  

Therefore, we will take option B will be correct. ( Answer )

6. Complete the two-column proof.
olya-2409 [2.1K]

Answer:

Given: \frac{x}{6} + 2 = 15                             ......[1]

To prove : x =78

Subtraction property states that you subtract the same number to both sides of an equation.

Subtract 2 from both sides of an equation [1];

\frac{x}{6} + 2 - 2= 15 -2

Simplify:

\frac{x}{6} = 13                                             ......[2]

Multiplication property states that you multiply the same number to both sides of an equation.

Multiply 6 to both sides of an equation [2];

\frac{x}{6} \times 6 = 13 \times 6

Simplify:

x = 78                      proved!

Statement                                           Reason

1.  \frac{x}{6} + 2 = 15                 Given

2.  \frac{x}{6} = 13                 Subtraction property of equality

3. x = 78                              Multiplication property of equality
