Answer:

x= 1.¯17948¯¯

Explain:

Isolate the variable by dividing each side by factors that don't contain the variable

Answer:

your answer is incorrect

Step-by-step explanation:

0.2 times (x+3) = 0.2x + .6

4(2x-3) = 4 x 2x + 4 x -3 = 4 x 2x + -7 = 6x + -7

0.2x + .6 - 6x + -7 = -5.8x + -7

because you cannot combine terms that are not alike, then your final answer would have to be -5.8x + -7 because you did not give us what x is equal to.

Answer:

hi, if im right i believe it would be option 2

Answer:

Step-by-step explanation:

solution: x=3;

extraneous solution: x=-1

The solution is 3 and the extraneous solution is -1.

The modulus function is the function which gives the magnitude or absolute of the number in the variable.

|x|=x if x>0

    -x if x<0

     0 if x=0

So according to question,

|7x+21|=14x

case-1: if 7x+21>0

⇒7x>-21

⇒x>-21/7

⇒x>-3

if 7x+21>0 , Using the modulus function property

|7x+21|=14x

⇒7x+21=14x

⇒14x-7x=21

⇒7x=21

⇒x=21/7

⇒x=3 which is also x>-3

x=3 is the solution

case-2:  if 7x+21<0

⇒7x<-21

⇒x<-21/7

⇒x<-3

if 7x+21<0 ,  Using the modulus function property

|7x+21|=14x

⇒-(7x+21)=14x

⇒-7x-21=14x

⇒14x+7x=-21

⇒21x=-21

⇒x=-21/21

⇒x=-1 for which x<-3 is not true

x=-1 is an extraneous solution.

Therefore the solution is 3 and the extraneous solution is -1.

Answer:

f(5) = 124

Step-by-step explanation:

Step 1: Define

f(x) = 22x + 14

f(5) = x = 5

Step 2: Substitute and evaluate

f(5) = 22(5) + 14

f(5) = 110 + 14

f(5) = 124

(x-7)(x-3)

x = 3,7

Answer: x = -44

Step-by-step explanation:

1/2(x - 10) = [tex]\frac{3}{4}[/tex] (x+8)    Apply the distributive property

1/2x  - 5 = 3/4x + 6       Add 5 to both sides

         +5              +5

  1/2x = 3/4x + 11    Subtract 3/4x  from both sides

-3/4x       -3/4x

    -1/4x = 11       Divide both sides by -1/4

     x =   -44

Answer:

50 batches

Step-by-step explanation:

A bag of flour = 5 pounds of flour

A batch of cookies = 0.10 pounds of flour

How many batches can be made with the 5-pound bag?

Batch of cookies in 5 pounds of flour = Total pounds of flour / flour needed per batch of cookies

= 5 pounds / 0.10 pounds

= 50 batches of cookies

50 batches of cookies can be made with 5 pounds of flour

(5 ; 3.5)

midpoint formula

(x₁ + x₂)/2 ; (y₁ + y₂)/2

(1  + 9)/2 ; (7 + 0)/2

(10/2 ; 7/2)

(5 ; 3.5)

Answer:

2.5

Step-by-step explanation:

When a variable is next to a number (coefficient) it means you need to multiply. In this equation 6x are next to eachother.

Because we don't know what x is, we have to work backwards.

The opposite of multiplying is dividing, so here we can do...

15/6  and that equals 2.5

To check you replace x with 2.5 like so,

6(2.5)= 15 and it is true!
