Answer:

x = 5.8

Step-by-step explanation:

2x + 9.4 = 21

Subtract 9.4 on both sides.

2x + 9.4 = 21

-9.4 -9.4

2x = 11.6

Divide by 3 on both sides to isolate the variable.

2x/2 = 11.6/2

x = 5.8

The graph means that 2 x and 9.4 make up 20 in total, so set up the equation 2x + 9.4 = 20.

Subtract 9.4 from both sides.

2x = 10.6

Divide by 2.

x = 5.3

The answer is the value of x that makes this equation true is 5.3

Hope this helps

If f(x) = StartFraction x Over 2 EndFraction + 8, what is f(x) when x = 10?
san4es73 [151]

Answer:

13

Step-by-step explanation:

You are given the function

f(x)=\dfrac{x}{2}+8

To find the value of the function f(x) at point x=a, you have to substitute a instead of x into the function expression.

In your case, you have to evaluate f(x) when x=10. Substitute 10 instead of x into the function expression:

f(10)=\dfrac{10}{2}+8=5+8=13

x= the number of pounds of the tropical taffy that should be used

You need to take the value of the Tropical Taffy + the value of the Passion Fruit taffy to = the value of Tropical Passion

value- price per pound times the number of pounds

Your equation is going to look like this-->

5.50x+625=6x+600

-5.50x        -5.50x

625=0.5x+600

-600         -600

25=0.5x

50=x

Hope this helps!

The standard form of a linear equation is Ax + By = C. Rewrite this equation in slope-slope-intercept form. What is the slope? W
myrzilka [38]
Standard form is Ax + By = C, or By = C - Ax.

Dividing both sides by B, we get y = C/B - (A/B)x

Here the y intercept is C/B, and the slope is -A/B.
