Answer: 6 miles!
Step-by-step explanation:
There are 5280 ft in a mile (you can remember this by saying five to-mat-os haha). In total, Lauren walked 16,900+14,850= 31,750 ft. To find how many miles she hiked you would simply divide by 5,280. I plugged this division problem into my calculator and got about 6 miles.
One number (a) exceeds another number (b) by 11 so
a = b+11
a + b = 77
Substitute the equation for a into the second equation
(b+11) + b = 77
multiply each side by 1 to remove parentheses
b + 11 + b = 77
Combine like terms
2b + 11 = 77
Isolate the variable
2b = 77-11
Simplify
2b = 66
Divide by 2
b = 33
Now substitute b back into the initial equation for a
a = (33) + 11
a = 44
Check your work by substituting both values into the second equation
44 + 33 = 77
This is true, so 44 and 33 are solutions
Answer:
is the right answer and other are wrong
1) She should fill the measuring cup 3 times. (B)
The answer is 1:3. You have to divide by the greatest number possible. In this case it is 2. So you divide 2 by 2, and 6 by 2.
