Answer:

x=11

Step-by-step explanation:

2x+5=27

Subtract 5 on both side of 27

Answer:

x=11 is the solution of the equation.

Step-by-step explanation:

SIMPLE EQUATIONS:-

2x+5=27. (By Transpotion Method)

2x=27-5. (Transposing 5 from LHS to RHS). (addition changes to subtraction)

2x=22. (Transposing 2 from LHS to RHS).

(multiplication changes to division)

x=22÷2.

x=11

Mikes movie Rentals Charge $3.00 for each rental plus $0.50 for each additional day. Reed's Rentals Charge $1.50 each rental plu
iris [78.8K]

Answer:

2

Step-by-step explanation:

What we need here is to express both charges trough equations, and then find out for which value these equations are equal.

Let X be the amount of additional days of rent.

So, Mikes Movie Rentals cost equations is:

CostMike = 3 + 0.5X

This implies that if there is no additional day (X=0), the cost is $3, if there is one additional day the cost is $3.5, for 2 days $4, and so on ...

Now lets find Reed's Rental cost.:

CostReed = 1.5 + 1.25X

And the interpretation is analogous to the one above. If there is no additional day, Reed's charge is $1.5, for 1 days $2.75, for 2 days $4

(Notice that with the examples I made about interpreting the equations I found out that for 2 days the cost of both is the same. Now lets find it analytically)

For finding the additional days that give the same costs we need to equal both equations:

3 + 0.5 X = 1.5 + 1.25 X

Lets subtract 1.5 from both sides:

3 - 1.5 + 0.5 X = 1.5 - 1.5 + 1.25 X

1.5 + 0.5 X = 1.25 X

Now subtract 0.5 X in both sides:

1.5 + 0.5 X - 0.5 X = 1.25 X - 0.5 X

1.5 = 0.75 X

Dividing both sides by 0.75:

1.5 / 0.75 = 0.75 X / 0.75

2 = X

So, for 2 additional days bith charges are equal.

Combine like terms to create an equivalent expression
klasskru [66]

Answer:

1/6a-1/6

Step-by-step explanation:

-2/3 transferred into 6th's is -4/6. You combine like terms, -4/6a+5/6a=1/6a

Then since -1/6 doesn't have a like term, it stays the same.

Phoenix [80]

Answer: 11/6 or 1 5/6

<u>Simplify 6/3</u>

6/3÷3/3=2/1

<u>Change 2/1</u>

2/1×6/6=12/6

New Problem: 12/6+(-1/6)

<u>Add</u>

12+-1/6=11/6

<u>Simplify</u>

11/6 = 1 5/6
