-2.4 < -2.40

This is false because they are equal to each other/they are the same number. So -2.4 can't be less than -2.40.

-2.4 ≠ -2.40

This is false because they are equal to each other, as they are the same number.

-2.4 ≤ -2.40

This is true because -2.4 is equal to -2.40

-2.4 > -2.40

This is false because they are the same number, so -2.40 can't be less than -2.4.

The third choice is your answer.

What is the y-coordinate of the solution to this system of equations?<br> 5x-8y=1<br> 3x+6y=-21

Vanyuwa [196]

5x-8y=1...(1)
3x+6y=-21...(2)

(1)*3:
15x-24y=3...(3)

(2)*5:
15x+30y=-105...(2)

(3)-(2):
15x-24y-(15x+30y)=3-(-105)
15x-24y-15x-30y=108
-54y=108
y=-2

3х2 = 147<br> Solve by undoing

Dmitry_Shevchenko [17]

Answer: +/- 7

Step-by-step explanation:

3x² = 147

To solve for x divide through by three first.

3x² = 147

x² = 49, now we take the square root of both side by trying to apply laws of indices.

√x² = √49

The square root will neutralize the effect of the square because

√a = a¹/² so (x²)¹/², and (x²)¹/² =

x²×¹/² = x, therefore the solution is

x = +/- 7.

Bad Investment After Mrs. Fisher lost 9% of her investment, she had $22,750. What was Mrs. Fisher's original investment?

stira [4]

Answer:

$2500

Step-by-step explanation:

Given that,

The lost percentage = 9%

Amount she had = $22,750

We need to find Mrs. Fisher's original investment.

As she had lost 9%, it means she will remain with 91% of her investment. Let the original investment is x.

So,

$91\%\ of \ x=22,750\\\\\dfrac{91}{100}x=22,750\\\\x=\dfrac{22,750\times 100}{91}\\\\x=\$25000$

So, her original investment is equal to $25000.
