Answer: 6mm
Step-by-step explanation: It is an equilateral triangle so all equal length so 18/3 sides equal to 6mm
Let one number be x.
Let the other number be y.
x + y = 49
x - y = 7
Subtracting both equations,
2y = 49 - 7 = 42
--- y = 21
--- x = 21 + 7 = 28
Hence the two numbers are 21 and 28.
First, lets convert the 1/8 of a mile into decimal form. To convert 1/8 to a decimal, divide the denominator into the numerator. 1 divided by 8 = . 125.
For the first 0.125 miles, its $1.75. So remove that from the ride cost and keep track of the 0.125 miles elsewhere.
$7.75 - $1.75 = $6
Miles: 0.125
We’re left with $6. Let’s divide the $6 by $0.30 to figure out how many miles the $6 will buy us.
6 / 0.30 = 20
So 0.30 goes into 6 twenty times.
So our answer will be the sum of 20 and 0.125.
20 + 0.125 = 20.125 Miles
Answer: $7.75 will buy you a 20.125 mile ride.
Answer number 3. Since it's obvious in the picture.
