8 + 4f = 3f solve for f

navik [9.2K]

Answer:

$f=-8$

Step-by-step explanation:

$8+4f=3f$

$8+4f-4f=3f-4f$ (Subtract $4f$ from both sides of the equation to isolate $f$ )

$8=-f$ (Simplify)

$-f=8$ (Symmetric Property of Equality)

$\frac{-f}{-1} =\frac{8}{-1}$ (Divide both sides of the equation by $-1$ to get rid of $f$ 's coefficient; remember that $-f=-1*f$ , so $-f$ has a coefficient of $-1$ )

$f=-8$ (Simplify)

Hope this helps!

a trapezoid has base lengths of (6x-1) units and 3 units. Its midsegment has a length of (5x-3) units. What is the value of x?

vodka [1.7K]

1. You have that:

- The lengths of the bases are (6x-1) units and 3 units.
- The midsegment has a length of (5x-3) units.

2. To solve this exercise, you must apply the formula for calculate the length of the midsegment of a trapezoid, which is shown below:

Midsegment=Base1+Base2/2

As you can see, the midsegment is half the sum of the bases of the trapezoid.

3. When you substitute the values, you obtain:

(5x-3)=[(6x-1)+3]/2

4. Now, you can solve the problem by clearing the "x":

(5x-3)=[(6x-1)+3]/2
2(5x-3)=6x-1+3
10x-6=6x+2
10x-6x=2+6
4x=8
x=8/4
x=2
