Answer:
1. They ate 1/6 of the donuts
2. 2/3
Step-by-step explanation:
1. They bought 18 donuts. 1/2 of 18 is 9. 1/3 of 9 is 3. To find the fraction, divide 3 by 18. Simplify the fraction. You are left with 1/6.
2. 1 1/3=4/3×1/2=4/6=2/3
Answer: 1 1/3
Step-by-step explanation: 7/15 plus 9/15 plus 4/15 equals 20/15 or 1 5/15. 5/15 divided by 5 equals 1/3. So the simplified answer is 1 1/3
Distance = SQRT(x^2+y^2)
x = 4 - (-2) = 6
y = 3 - 2 = 1
distance = SQRT(6^2 + 1^2) = SQRT(36+1) = SQRT(37) = 6.1
<em>Answer:</em>
<em>x = 6</em>
<em>Step-by-step explanation:</em>
<em>2 + 7x = 5x + 14</em>
<em>7x - 5x = 14 - 2</em>
<em>2x = 12</em>
<em>x = 12 : 2</em>
<em>x = 6</em>
<em>Good luck !</em>
This is a linear relationship as the rate of change is constant, ie constant velocity. And the slope represents the velocity, and slope is:
m=(y2-y1)/(x2-x1)
m=(50-25)/(2-1)=25/1
m=25
So the rate of change is 25 mph
