Answer:
<h3>8 and 13</h3>
Step-by-step explanation:
Let the two numbers be x and y
If the two numbers differs by 5, then;
y-x = 5 ...1
x is the smaller
y is the larger
If seven times the smaller plus four times the larger is 108, this is expressed as;
7x + 4y = 108 ... 2
From 1;
y = 5 + x .... 3
Substitute 3 into 2;
From 2;
7x + 4y = 108
7x + 4(5+x) = 108
7x + 20 + 4x = 108
11x + 20 = 108
11x = 108-20
11x = 88
x = 88/11
x = 8
Since y = 5+x
y = 5 + 8
y = 13
hence the numbers are 8 and 13

Answer:
speed = distance/time
Step-by-step explanation:
The faster a sound wave travels, the more distance it will cover in the same period of time. If a sound wave were observed to travel a distance of 700 meters in 2 seconds, then the speed of the wave would be 350 m/s.
