Answer:
so the first one i think is 1 and the second one is 4
Step-by-step explanation:
Let the two numbers be x and y.
x + y = 86
+
x - y = 12
_________
2x + 0 = 98
__________
2x = 98
x = 98/2
x = 49
From x + y = 86
49 + y = 86
y = 86 - 49
y = 37
The numbers are 49 and 37.
Answer:
120 times
Step-by-step explanation:
If we want to find a qunatity is how many times as other quantity, we have to divide the large one by the small one (remember, same units).
Let's make both into inches.
We have 1 inch [model]
also
10 feet * 12 = 120 inches
Thus, we can say:
120/1 = 120 times
So, Actual Plane is 120 times than model airplane
