Complete the two-column proof. Given:x5+9=11 Given: x 5 + 9 = 11 Prove x=10 Prove x = 10 x5+9=11 x 5 + 9 = 11 a._______ x5=2 x 5
avanturin [10]

<u>Statement  </u>                                       <u>Reason</u>

<u>\frac{x}{5} +9 = 11\\          </u>    Given

Subtract 9 from both the sides

<u>\frac{x}{5} +9-9 = 11-9\\</u><u>       </u>    Subtracting same number will not        affect equation

\frac{x}{5}  = 2\\                           Simplification

\frac{x}{5}*5  = 2*5(\\                   Multiplying by 5 both the sides

x= 10                                                           By simplifying both the sides

Thus we solved the equation and got x =10 as answer.

denpristay [2]

Answer:

(a) i believe it is $10

(b)I believe it is 98 people

Step-by-step explanation:

(a) we are trying to find "?" for this explanation. I came up with the equation 60=6 x ?. The 60 shows us the total amount of dollars that the 6 shares went down. We need to find the amount. of dollars that went down for 1 stock. So we divide 60 by 6. and get 10.

(b) we are trying to find "?" for this explanation. I came up with the equation

?=7 x 14. All you have to so is multiply 7 by 14 and you get 98.

Hope this helps :)
