What is the value of x in the equation x - y = 30, when y = 15? O4 O 8 O 80 O 200

olganol [36]

$\frac{1}{5}x - \frac{2}{3} y = 30 \\$

Putting the value of Y = 15

$\frac{1}{5} x - \frac{2}{3} \times 15 = 30 \\ \frac{1}{5} x = 30 + 10 \\ \frac{1}{5} x = 40 \\ x = 5 \times 40 \\ x = 200$

So, X = 200

Which products result in a perfect square trinomial? Check all that apply.

sladkih [1.3K]

The correct answers are:

B=(xy + x)(xy + x) ; C=(2x – 3)(–3 + 2x) ; and E=(4y² + 25)(25 + 4y²)

Explanation:

In order to have a perfect square trinomial, we must multiply two binomials that are exactly the same. For (xy+x)(xy+x), are multiplying two identical binomials.

For (2x-3)(-3+2x), we are multiplying two binomials that are the same but written in a different order. The same is true of (4y² + 25)(25 + 4y²).

What is 5/4, 1 8/25, and 1.3 in least to greatest

stiks02 [169]

$\text{Hey there!}$

$\dfrac{5}{4}, 1\dfrac{8}{25}, \&\ 1.3$

$\text{Least}\rightarrow \text{greatest}$

$\dfrac{5}{4} = 1.25$

$1\dfrac{8}{25}=\dfrac{33}{25}= 1.32$

$\text{1.3 =}\dfrac{13}{10}$

$\text{Now, that we simplified the fraction to a decimal/ decimal to a fraction}\\\text{we can solve for the answer you're looking for!}$

$\boxed{\bf{Answer: \dfrac{5}{4}}\rightarrow1.3\rightarrow 1\dfrac{8}{25}}\checkmark$

$\text{Good luck on your assignment and enjoy your day!}$
