Answer:
nothing is the difference
Answer:
16
Step-by-step explanation:
400-150=250
250/15=~16
The length of a table, the width of a classroom, and the length of a car can be easily measured without using trigonometry (could probably use a meter stick or measuring tape) because we can easily reach both ends
the width of a wide river is a little different, it may not be practical to measure the distance across directly.
Let the smaller number be x and the larger one be y
x + y = 77
y = x + 5
Substituting into the first equation
x + (x + 5) = 77
2x + 5 = 77
Subtracting 5 to both sides
2x +5 -5 = 77-5
2x = 72
Divide both sides by 2
2x/2 = 72/2
x = 36
