5-2(x+1)=13 what is x

Answers

Answer 1

Answer:

x=-5

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5−2(x+1)=13

5+(−2)(x)+(−2)(1)=13 (Distribute)

5+−2x+−2=13

(−2x)+(5+−2)=13 (Combine Like Terms)

−2x+3=13

−2x+3=13

Step 2: Subtract 3 from both sides.

−2x+3−3=13−3

−2x=10

Step 3: Divide both sides by -2.

−2x −2 = 10

−2 x=−5

Answer:

x=-5

Answer 2

Question:

5-2(x+1)=13what is this value of x

Answer:-

x=-5

Solution:

[tex]\mapsto:\bold{5-2(x+1)=13   }[/tex] 

[tex]\mapsto:\bold{-2(x+1)=13-5   }[/tex] 

[tex]\mapsto:\bold{(-2\times x)+(-2\times 1)=8   }[/tex] 

[tex]\mapsto:\bold{-2x+(-2)=8   }[/tex] 

[tex]\mapsto:\bold{-2x-2=8   }[/tex] 

[tex]\mapsto:\bold{-2x=8+2   }[/tex] 

[tex]\mapsto:\bold{-2x=10   }[/tex] 

[tex]\mapsto:\bold{ x=\dfrac{10}{-2}   }[/tex] 

[tex]\dashrightarrow:\bold{ x=-5  }[/tex]

Which number in the set {6, 12, 18, 36} satisfies the equation 6x - 18 = 54?

Answers

Answer:

Here we can go for trial and error,

Taking x=6

So equation will be 6*6-18 which gives 18

and is not equal to 54

So it's, not 6

Trying 12

6*12-18

Which is 54 and so correct answer is x=12

A company claims that its new bottle holds 25% more laundry soap. If their original container held 53 fluid ounces of soap, how much does the new container hold?
PLEASE HELP!

Answers

Answer:

66.25 ounces of soup

Step-by-step explanation:  

The  new container will contain 53 + 13.25 = 66.25 ounces of soap.

Hope that helps!

The new container hold 66.25 ounces.

Let x represent the capacity of the new container.

Since the new bottle holds 25% more laundry soap and the original container held 53 fluid ounces of soap, hence:

Additional space for the new container = 25% * 53 fluid ounces = 13.25 ounces

Hence:

New container capacity = 13.25 ounces + 53 ounce = 66.25 ounces

Hence the new container hold 66.25 ounces.
