Answer:

18

Step-by-step explanation:

(5/6)x – 4 = 11

(5/6)x = 11 + 4

(5/6)x = 15

5x = 15×6 = 90

x = 90/5 = 18

Answer:

x = 18

Step-by-step explanation:

5/6x - 4 = 11

Add 4 to each side

5/6x - 4+4 = 11+4

5/6x = 15

Multiply by 6/5 to isolate x

6/5 * 5/6x = 15 * 6/5

x = 18

Eduardo puts $40 into his piggy bank and plans to add $5 each month. Write an equation to represent this.​
igomit [66]

Answer:

40+5x

Step-by-step explanation:

Eduardo put $40 in so the 40 is what he has already put in. Next you have $5 added in but it doesn’t say for how many months just that it’s each month so we put the x to represent out unknown so we can solve the equation.

AB = x + 3
torisob [31]

Answer:

Step-by-step explanation:

IF it is a SYMMETRIC kite

            CB = CD

         x + 4 = 2x - 1

x - x + 4 + 1 = 2x - x - 1 + 1

                5 = x

  AB = AD

x + 3 = 3x - y

5 + 3 = 3(5) - y

     8 = 15 - y

      y = 7

Kevin and Randy Muise have a jar containing 92 coins, all of which are either quarters or nickels. The total value of the coins
Artemon [7]
<span>Let n = the number of nickles
Let q = the number of quarters
Then for your problem we have
(1) n + q = 43 and
(2) 5*n + 25*q = 100*6.95 (always work in cents to avoid decimal numbers) or
(3) 5*n + 25*q = 695
Now substitute n of (1) into (3) and get
(4) 5*(43 - q) + 25*q = 695 or
(5) 215 - 5*q + 25*q = 695 or
(6) 20*q = 695 - 215 or

(7) 20*q = 480 or
(8) q = 24
Then using (1) we get
(9) n + 24 = 43 or
(10) n = 19
Let's check these values.
Is (.05*19 + .25*24 = 6.95)?
Is (.95 + 6.00 = 6.95)?
Is (6.95 = 6.95)? Yes
Answer: Kevin and Randy have 19 nickles and 24 quarters in the jar.</span>

What is the solution to the equation 2(x - 3) = 2x + 5
Genrish500 [490]
Hello there!

2(x - 3) = 2x + 5

Let's start by using the distributive property for the left side.

(2)(x) + (2)(-3) = 2x + 5

2x - 6 = 2x + 5

Then we need to add 6 to both sides

2x - 6 + 6 = 2x + 5 + 6

2x = 2x + 11

We need to transfer 2x on the left side, we gonna do that by subtracting 2x from both sides

2x - 2x = 2x + 11 - 2x

0 = 11

Thus,

There are no solutions.

I hope this helps!

Good luck with your career!
