If x varies directly as y, then what is y when x = 4,<br> knowing that x = 60 when y = 5?
Basile [38]

Answer:  The answer would be 1/2

Step-by-step explanation:

<em>Y varies DIRECTLY as x. Find the constant of variation, k, if y = -5x </em>

<em>The first sentence is there for information, the constant is a number( 1,2,3...so on) , so the only number is -5 </em>

<em>It is a linear equation meaning equation of a straight line. </em>

<em>its form is y= mx+b, where m is the slope of the line, b is the y intercept when x=0. these info you have to memorize like your life depend on it. </em>

<em>next, y varies directly as x. If y = 15 when x = 60, find y when x = 100 </em>

<em>if y= 15, when x=60, then there is a number m such that m*y= 60 </em>

<em>or m= 60/y= 60/15 =4 </em>

<em>so the equation is y=4x. in this cause, the b=0 </em>

<em>so when x=0, y=0 </em>

<em>The distance a car travels at a constant speed varies directly as the time the car spends traveling. If a car traveled 105 miles in 3 hours, how far could the car travel in 5 hours? </em>

<em>remember that distance = speed times time. </em>

<em>or d=Vt </em>

<em>so car goes 105 miles on 3 hours </em>

<em>how far it goes in one hour? </em>

<em>if you know that, then you can tell how far it goes in 5 hours.</em>

<em>Hope I made it non tough enough</em>

Kendra swims 126 miles in 3 days, what is the constant rate that Kendra swims per day? a. 40 miles per day c. 42 miles per day b
Leni [432]

Answer:

c. 42 miles per day

Step-by-step explanation:

From the information given, you can use a rule of three to calculate the constant rate that Kendra swims per day given that she swims 126 miles in 3 days:

3 days → 126 miles

1 day   →        x

x=(1*126)/3=42 miles

According to this, the answer is that Kendra swims 42 miles per day.
