How many solutions does this equation have? -2-5x= -(5x+2)
Leno4ka [110]

Answer:

Infinite solutions

Step-by-step explanation:

A linear equation is given to us and we need to tell the no. of solutions. The equation is ,

=> -2-5x = - ( 5x +2)

If we look at RHS , negative sign is present outside the brackets .On opening the brackets , we have ,

=> -(5x) -(+2)

=> -5x -2

=> -2 - 5x

This is similar to LHS and hence they will represent same line . Hence they will have infinitely many solutions .

<h3><u>They have infinitely many solutions .</u></h3>

During a sale a store offered a 35% discount on a particular camera that was originally priced at $234. After the sale, the disc
ch4aika [34]

Answer: $205.33

Step-by-step explanation:

We know the original price was $234, during the sale there was a 35% discount, let's found out what that is...

234 * (100% - 35%)

234 * (65%)

234 * (0.65)

= 152.1

After the sale, the price was increased by 35%, remember percentages are out of 100...

100% + 35% = 135%

135% = 1.35

152.1 * 1.35

= $205.33

The price of the camera after the increase is $205.33, I hope this helps!

Hillary rolls 2 number cubes numbered 1 through 6 while playing her favorite board game. She will get a second turn if she rolls
Nataly [62]

Answer:

1 in 18

Step-by-step explanation:

The highest possible number Hillary can get is 12, meaning that the only odd number above 10 which she can get is 11.

There are two possible ways in which Hillary can get 11:

(a) Hillary rolls a 5 on her first cube and a 6 on her second cube

(b) Hillary rolls a 6 on her first cube and a 5 on her second cube

There are 34 other possible outcomes which Hillary can have when rolling her number cubes, for a total of 36 possible outcomes.

Since 2 of these outcomes result in a roll of 11, Hillary has a 2 in 36 chance of rolling an 11, which can be simplified as 1 in 18.
