3x + 4 = y Solve the formula for x.

1 answer:

4 0

Hello!

To solve an equation for a particular variable, you must isolate the given variable on one side of the equation. We'll begin by restating the given formula:

3x + 4 = y

Now subtract 4 from both sides of the equation:

3x = y – 4

Now divide both sides by 3:

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

We have now proven that X is equal to $\frac{y-4}{3}$ .

I hope this helps!

Tom [10]

Answer:

AC ≈ 2.18 units

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan70° = $\frac{opposite}{adjacent}$ = $\frac{BC}{AC}$ = $\frac{6}{AC}$ ( multiply both sides by AC )

AC × tan70° = 6 ( divide both sides by tan70° )

AC = $\frac{6}{tan70}$ ≈ 2.18 ( to the nearest hundredth )

A golf course in Phoenix, Arizona, uses an average of 80 million gallons of water daily for irrigation. An average family of fou

olasank [31]

Answer:

250 families

Step-by-step explanation:

Given that ;

Amount of water used by the golf course is 80,000,000 gallons per day

Amount of water used a family of four is 325,851 gallons per year

It is clear here that the amount of water used per day to water the golf course can be used by several families of four per year because a family of four just requires 325,851 gallons of water per year.

To find the number of families of four, you divide the amount used to water the golf course with the amount used by a single family of four.

<u>Number of families</u>

$=\frac{80,000,000}{325,851} =245.51=246$

=246 to the nearest ten will be 250 because the value in the ones position is greater than 5 thus 246 changes to 250

Bond [772]

If Sixty-five randomly selected car salespersons were asked the number of cars they generally sell in one week. Then the mean of the sample is 3.75.

The average of a group of numbers is simply defined as the mean. In statistics, the mean is regarded as one of the indicators of central tendency.

Sixty-five randomly selected car salespersons were asked the number of cars they generally sell in one week.

Fourteen people answered that they generally sell two cars; nineteen generally sell three cars; twelve generally sell four cars; nine generally sell five cars; eleven generally sell six cars.

Then the mean of the sample will be
