So, Vanessa's score = v. Let's work from there.

We know that 59 is decreased by Vanessa's score, which is subtraction, and thus: 59 - v

Then, we're told that that quantity is 7. "Is" can be used in place of an equals sign: = 7

Therefore, our equation is as follows: 59 - v = 7

Hope this helps!! :)

2w-1 divided by 5+w+2=2w
FromTheMoon [43]

Answer:

(2w-1)/5+w+2=2w

We simplify the equation to the form, which is simple to understand  

(2w-1)/5+w+2=2w

Reorder the terms in parentheses

( + 0.4w-0.2)+w+2=2w

Remove unnecessary parentheses

+ 0.4w-0.2+w+2=2w

We move all terms containing w to the left and all other terms to the right.  

+ 0.4w+1w-2w=0.2-2

We simplify left and right side of the equation.  

-0.6w=-1.8

We divide both sides of the equation by -0.6 to get w.  

w=3

Kara has 21 collectible buttons to sell. She sells the small buttons for $3 and the large buttons for $4, and earns a total of $
Serga [27]
We know that there are 21 buttons total. x is the number of small buttons and y is the number of large buttons. 

Therefore, our first equation should be x+y = 21.

We know the small buttons sell for 3 dollars, meaning 3x represents how much is made from the small buttons. The larger buttons sell for 4 dollars, meaning 4y is how much is made from the large buttons. 

We also know that the total of the buttons sold is 68 dollars. Therefore 3x + 4y = 68 is our second equation.

From this information, the answer is the first set.
