Mary is 63.5 inches tall and her sister Tonya is 70 inches tall. Tonya wants to know how many inches taller she is than Mary. Which equation and solution can be used to solve this problem?
-Subtract 70 from both sides. The answer is 6.5 inches.
-Subtract 63.5 from both sides. The answer is 6.5 inches.
- Add 63.5 to the left side and subtract 63.5 from the right side. The answer is 6.5 inches.
- Subtract 63.5 from both sides. The answer is 6.5 inches

Subtract 63.5 from both sides. The answer is 6.5 inches.

Step-by-step explanation:

Set up an equation:

70 = x + 63.5

Where x is the number of inches Mary needs to grow to be the same height as Tonya

Subtract 63.5 on both sides:

70 = x + 63.5

-63.5    -63.5

6.5 = x

Therefore, Tonya is 6.5 inches taller than Mary.

on your paper it doesn't say the answer but the the answer is altitude

step-by-step explanation:

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
