Solve for x. 2x−45=x+4 Enter your answer in the box. x =

nata0808 [166]

2x - 45 = x +4

Add 45 to each side:

2x = x + 49

Subtract 1x from each side:

x = 49

The formula V = IR shows the relationship between voltage, current, and resistance. Solve this formula for R.

Tema [17]

Simply view this formula as an equation and solve for R
This would look like:
V=IR
V/I=R/I
V/I=R
ANSWER
R=v divided by I

For f(x) = square root of x, estimate f(17) to the nearest integer.

Tomtit [17]

f(x) = sqrt(x)

f(17) = sqrt(17)

it is close to sqrt(16)=4

so to the nearest integer

f(17) = 4

The denominator of a fraction is two more than the numerator. If both numerator and denominator are decreased by six, the simpli

ira [324]

Answer:

$\dfrac{40}{42}$

Step-by-step explanation:

Let the numerator of the fraction=x

Since the denominator of a fraction is two more than the numerator.

Denominator=x+2

The fraction is therefore:

$\dfrac{x}{x+2}$

If both numerator and denominator are decreased by six, the fraction becomes:

$\dfrac{x-6}{x+2-6}$

The simplified result is $\dfrac{17}{18}$

Therefore:

$\dfrac{x-6}{x+2-6}=\dfrac{17}{18}\\$Next, we solve for x\\Cross multiply\\18(x-6)=17(x+2-6)\\18(x-6)=17(x-4)\\Expand the bracket\\18x-108=17x-68\\Collect like terms\\18x-17x=-68+108\\x=40$

Substituting x=40 into the initial fraction

$\dfrac{x}{x+2}=\dfrac{40}{40+2}=\dfrac{40}{42}$

Therefore, the original fraction is $\dfrac{40}{42}$
