Write your answer as a fraction in simplest form subtract 5/8-3/5
svetoff [14.1K]

first you need to find the least common denominator which in this case it is 40. since 5 and 8 both go into 40.


5/8 = 25/40

3/5 = 24/40

25/40 - 24/40 =1/40

does this make sense to you?

The sum of two numbers is 9 . one number is nine less than twice the other. find the two numbers.
dimulka [17.4K]
Hello!

To solve this problem, we will use a system of equations. We will have one number be x and the other y. We will use substitutions to solve for each variable.

x+y=9
x=2y-9

To solve for the two numbers, we need to solve the top equation. The second equation shows that x=2y-9. In the first equation, we can replace 2y-9 for x and solve.

2y-9+y=9
3y-9=9
3y=18
y=6

We now know the value of y. Now we need to find x. We can plug in 6 for y in the second equation to find x.

x=2·6-9
x=12-9
x=3

Just to check, we will plug these two numbers into the first equation.


3+6=9
9=9

Our two numbers are three and six.

I hope this helps!

What is the approximate circumference of the circle shown below?
Crank

Answer

Formula

Circumference\ of\ circle = 2\pi r

where r is the radius of a circle.

As shown in the image

Diameter of the circle = 16 .3 cm

Radius\ of\ the\ circle = \frac{16.3}{2}

                                   = 8.15 cm

Put in the formula

Circumference\ of\ circle = 2\pi\times 8.15

As

\pi = 3.14

Circumference\ of\ circle = 2\times 3.14\times 8.15

                                                 = 51.2 cm (approx)

Therefore the circumference of a circle is 51.2cm (approx) .

Option (D) is correct .
