Take the cube root of both sides. Or, if you cant see that, just plug in each awnser and see which one ends up being correct. 6^3=216

Michelle plans on raising $80 for her softball team. To raise the money, she is selling team shirts for $10 each.

8_murik_8 [283]

Given:

Michelle plans on raising $80.

Selling price of each shirt = $10

So far she has raised $20.

To find:

The number of more shirts she needs to sell.

Solution:

Let x be the number of more shirts she needs to sell.

Selling price of one shirt = $10

Selling price of x shirt = $10x

Total raising amount = $(10x + 20)

Michelle plans on raising $80. So,

$10x+20=80$

Subtract both sides by 20.

$10x=80-20$

$10x=60$

Divide both sides by 10.

$x=\dfrac{60}{10}$

$x=6$

So, the required equation is $10x+20=80$

Therefore, the correct option is A.

Answer: second option

Step-by-step explanation:

The standard form of a quadratic equation is:

$ax^2+bx+c=0$

Then, to write the quadratic equation given in the problem in standard form, you must substract 1 from both sides of the equation. Then you have:

$2x^2+5x-1=0$

Given the quadratic equation above, to find the value of $b^2-4ac$ you must substitute:

a=2; b=5 and c=-1 into $b^2-4ac$

Thenrefore, you obtain the following result:

$5^2-4(2)(-1)=33$
