Solving rational equations solve for x: 3/x-4=7/x

KIM [24]

Solving the rational equation $\frac{3}{x-4}=\frac{7}{x}$ the value of x is 7

Step-by-step explanation:

We need to solve rational equation: $\frac{3}{x-4}=\frac{7}{x}$ and find value of x.

Solving:

$\frac{3}{x-4}=\frac{7}{x}$

Cross multiplying:

$3(x)=7(x-4)\\Simplifying:\\3x=7x-28\\3x-7x=-28\\-4x=-28\\x=-28/-4\\x=7$

So, value of x = 7.

Solving the rational equation $\frac{3}{x-4}=\frac{7}{x}$ the value of x is 7

The cost for x number of gallons of heating oil can be represented by the function f(x)=4x+6 in the context of the problem expla

deff fn [24]

Answer:

This means that the cost of 2 heating oil gallons is 14.

Step-by-step explanation:

f(x) = 4x + 6 , where x is the number of heating oil gallons.

And f(x) = 4x + 6 is the equation for the cost of x gallons.

When the number of gallons are 2 then the cost is;

f(2) = 4(2) + 6 = 8 + 6 = 14

This means that the cost of 2 heating oil gallons is 14.

Solve for x Find ADB Find BDC

NeTakaya

Answer:

x=12 ADB= 56 BDC= 54

Step-by-step explanation:

ADB and BDC are complementary, so they add up to 90 degrees. In other words ADB+BDC= 90 So I can input my knowns into the equation

(3x+10) + (4x-4) = 90

I combined like terms to give me 7x+6=90

Then I subtract 6 from both sides giving me 7x=84

Last I divide 7 on both sides. x=12

Then I input the x (12) into the equation and solve it from there

3(12)+10 and 4(12)-4

3(12)+10=56

4(12)-4=54

. . . I think. Hope this helps!
