X and y simplifying problem. Please explain how to do thiese. I will gove 15 points

$\dfrac 56 x + \dfrac25 y - \dfrac14 x + \dfrac3{10} y$

First, combine like terms:

$\left(\dfrac 56 - \dfrac14\right) x + \left(\dfrac25 + \dfrac3{10}\right)y$

Now just simplify the coefficients of x and y. We do this by converting each pair of fractions to ones with a common denominator. Then we can combine them easily.

$\dfrac56 - \dfrac14 = \dfrac56\cdot\dfrac22 - \dfrac14\cdot\dfrac33 = \dfrac{5\cdot2}{6\cdot2} - \dfrac{1\cdot3}{4\cdot3} = \dfrac{10}{12} - \dfrac3{12} = \dfrac{10-3}{12} = \dfrac7{12}$

$\dfrac25 + \dfrac3{10} = \dfrac25\cdot\dfrac22 + \dfrac3{10} = \dfrac{2\cdot2}{5\cdot2} + \dfrac3{10} = \dfrac4{10} + \dfrac3{10} = \dfrac{4+3}{10} = \dfrac7{10}$

So the simplified expression would be

$\dfrac7{12} x + \dfrac7{10} y$

Decide whether each expression is equivalent to 0.75t-21. 3/4t-21 3/4( t-21) 0.75( t-28) t-0.25t-21. Explain how you know

butalik [34]

Answer: expression 1,3 and 4 are equivalent to 0.75t-21.

Step-by-step explanation:

Expression 1

3/4t-21

= 0.75t - 21

Expression 2

3/4( t-21)

Multiply through by 0.75

= 0.75 ( t - 21 )

= 0.75t - 15.75

Expression 3

0.75( t-28)

Multiply through by 0.75

= 0.75t - 21

Expression 4

t-0.25t-21

let t = 1

1-0.25t - 21

= 0.75t - 21

expression 1,3 and 4 are equivalent to 0.75t-21.

Pls help I’ll brainlest

Afina-wow [57]

Answer: A (32,100,000

Step-by-step explanation:

My answer is correct because, All you have to do is multiply 3.21 times $10^{7}$ .

To make it easier we have to simlify $10^{7}$ . $10^{7}$ equals 10000000. So now we just have tii multiply 3.21 and 10000000. 3.21 times 10000000 equals 32,100,000.

Hope This Helps!

(P.S: Thanks so much for sending this question now because of it im rank ace! Thanks so much and I will remember this question as the question that took me a rank up!)
