What is 9 2/5-8 1/3 I need to know for math tomorrow

patriot [66]

Answer:

$1\frac{1}{15}$

Step-by-step explanation:

Let's use a start by using common denominators. $9\frac{2}{5} = 9\frac{6}{15}$ and $8\frac{1}{3} = 8 \frac{5}{15}$

Now, replace the original equation with the common denominators. $9\frac{6}{15} - 8\frac{5}{15}$

Solve! $9\frac{6}{15} - 8\frac{5}{15} = 1\frac{1}{15}$

If x varies directly as y, then what is y when x = 4, knowing that x = 60 when y = 5?

Basile [38]

Answer: The answer would be 1/2

Step-by-step explanation:

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

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

It is a linear equation meaning equation of a straight line.

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.

next, y varies directly as x. If y = 15 when x = 60, find y when x = 100

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

or m= 60/y= 60/15 =4

so the equation is y=4x. in this cause, the b=0

so when x=0, y=0

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?

remember that distance = speed times time.

or d=Vt

so car goes 105 miles on 3 hours

how far it goes in one hour?

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

Hope I made it non tough enough

The volume will increase as each layer is added because you are adding more to that certain shape
