Answer:
1/4
Step-by-step explanation:
To find the slope given two points
m = (y2-y1) / (x2-x1)
= (4-3)/(5-1)
= 1/4
There are 4 quarts in a gallon so 1/4 is a quart
What????? Um I’m so sorry I don’t know
The answer is <span>twelve sevenths (12/7)
</span>
x - the job<span>
t - time to do the job x
</span><span>Robin can mow a lawn in 3 hours: x/3 * t
</span><span>Brady can mow the same lawn in 4 hours: x/4 * t
</span><span>If they work together, the total work will
be the sum of their speeds:
</span>x = x/3 * t + x/4 * t = (x/3 + x/4)*t = (4x/12 + 3x/12) * t = 7x/12 * t
x = 7x/12 * t
Divide both sides by x:
x/x = 7x/12 * t/x
1 = 7/12 t
t = 1 : 7/12
t = 12/7
