Because if they arent then they arent truly similar . they would be ovals.

Crystal wants to add the fractions 1/16 and 3/18 what is the lowest common denominator of the two fractions?

zhenek [66]

Answer:

288

Step-by-step explanation:

First, simplify the fraction 3/18 to 1/6, this will help a lot. Then, you just, find the LCM, and you can list out the mutliples to help you

6, 12, 18, 24, 39, 36, 42, 48, 54, 60

16, 32, 48, 64, 80

It would be easiest to do 48

But that's not exactly what the question is asking

It's asking the LCM of 1/16 and 3/18

I wanted to show you the other way so you would be able to think of it in a different way which would be easier

You would just list out the multiples again.

18, 36, 54, 72, 90, 108, 126, 135, 153, 171, 189

16, 32, 48, 64, 80, 96, 112, 130, 146, 162, 178, 194

Ok, I give up on that

Let's just do 16*18 which is 288.

288 is your LCM

Sometimes multiplying is easier and other times listing it out is easier.

I hope this helped

4 plates and 3 cups cost 20.70 dollars. 5 plates and 4 cups cost 26.40 dollars . each plates cost the same amount as the other p

Basile [38]

Here, we need to construct 2 linear equation.
Let x be the plate and y be the cup.
1) 4x + 3y = 20.70
2) 5x + 4y = 26.40

From equation 1, we solve for y.
3y = 20.70 - 4x
y = (20.70 - 4x) / 3

Substitute into equation 2.
5x + 4((20.70 - 4x) / 3) = 26.40
5x + 27.60 - 5.33x = 26.40
-0.33x = 26.40 - 27.60
-0.33x = -1.2
x = 3.64

We already get value of x. Now, calculate for value of y.
y = (20.70 - 4x) / 3
y = (20.70 - 4(3.64)) / 3
y = 2.05

The cost for 1 plate is 3.64 dollars and 1 cup is 2.05 dollars.

I WILL AWARD BRAINLIEST TO RIGHT ANSWER

Jet001 [13]

Answer:

y = -2000x+30000

Step-by-step explanation:

Hi. So, you are just setting up a linear equation using slope intercept data. The slope being -2000 (because it is descending) and the intercept being 30,000 at t=0.

y = -2000x+30000

If f(x)=4x^2+1 and g(x) =x^2-5 find (f-g)(x)

docker41 [41]

Answer:

$\huge\boxed{(f-g)(x)=3x^2+6}$

Step-by-step explanation:

$(f-g)(x)=f(x)(x)\\\\\text{substitute}\ f(x)=4x^2+1\ \text{and}\ g(x)=x^2-5\\\\(f-g)(x)=(4x^2+1)-(x^2-5)=4x^2+1-x^2-(-5)=4x^2+1-x^2+5\\\\\text{combine like terms}\\\\(f-g)(x)=(4x^2-x^2)+(1+5)=3x^2+6$
