1/3x+3=13 what is the answer for x

Mathematics
2 answers:
Margaret [11]3 years ago
4 0

Step-by-step explanation:

I'm not sure if the question is \frac{1}{3}x + 3 = 13 or \frac{1}{3x} + 3 = 13, so we can do both:

\frac{1}{3}x + 3 = 13

First, let's subtract 3 from both sides to isolate the x on the left-hand side:

\frac{1}{3}x = 10

Next, let's multiply both sides by 3 to get x by itself:

x = 30

\frac{1}{3x} + 3 = 13

First, let's subtract 3 from both sides to isolate the x on the left-hand side:

\frac{1}{3x} = 10

Next, we can take the reciprocal of both sides to get rid of the fraction on the side with x:

3x = \frac{1}{10}

Next, we can divide both sides by 3 to get x by itself:

x = \frac{1}{30}

Answer:

x = 30

Step-by-step explanation:

to solve for value of x in this expression 1/3x+3=13

solution

1/3x+3=13

collect the like terms

1/3x = 13 -3

1/3x = 10

multiply through by 3

x = 30

6(1 + 3R) = 2(10R - 9) -4R
Damm [24]

Answer:

R=-12

Step-by-step explanation:

6(1 + 3R) = 2(10R - 9) -4R

Distribute 6 through the parentheses

6+18R=2(10R-9)-4R

Distribute 2 through the parentheses

6+18R=20R-18-4R

Collect like terms

6+18R=16R-18

Move the variable to the left-hand side and change its sign

6+18R-16R=-18

Move the constant to the right-hand side and change its sign

18R-16R=-18-6

Collect like terms

2R=-18-6

Calculate the difference

2R=-24

Divide both sides of the equation by 2

R=-12

if you'd make me brainliest that'd be great, if not its ok as well! I hope this helped!!!

Item 11 Identify the independent and dependent variables. The equation c=0.09s gives the amount c (in dollars) of commission a s
diamong [38]

Answer:

C is dependent variable

S is independent variable

Step-by-step explanation:

Here, give the equation, we are told to identify the independent and the dependent variable

When we talk of the independent variable, it is that variable which values does not depend on whatever values the second variable in the equation has. It is that variable that is used to find the other variable in the equation

While the dependent variable depends on the values we input in the equation. It is the variable that we arrive at after plugging different values for the independent variable

now looking at the question, the equation we have is as follows;

c = 0.09s

To get the value of c which is the cost , we have to input different values of a. As is the amount in sales that we have that will yield the value of the commission to be received

Thus, we can categorically say that the values of the commission are dependent on the values we get from the sales

Hence, while commission represents the dependent variable, the values of the sales are the independent variables
