What is 3(x-5)-14=2(x-7)+2

Evgen [1.6K]

Answer: x = 7

Step-by-step explanation:

To solve the equation,

First step, open the bracket

3(x-5)-14=2(x-7)+2

3x -15 -14 = 2x -14 +2

Then, add the like terms

3x - 29 = 2x -16

Transpose the values at the right hand side to the left hand side

3x - 2x = -16 + 29

x = 7

333 erasers cost \$4.41$4.41dollar sign, 4, point, 41. Which equation would help determine the cost of 444 erasers? Choose 1 ans

Rudiy27

Answer:

Option D will be correct.

Step-by-step explanation:

The 333 erasers cost $4.41.

We have to determine the cost of 444 erasers.

Let the price of 444 erasers is $x.

Therefore, since the number of erasers cost per dollars is constant, hence the equation that would help to determine the cost of 444 erasers will be $\frac{333}{4.41} = \frac{444}{x}$

⇒ $\frac{3}{4.41} = \frac{4}{x}$

Therefore, option D will be correct. (Answer)

Find the value of x. Round your answer to the nearest tenth

Sati [7]

$x=13.8$

<u><em>Step-by-step explanation:</em></u>

Since the triangle is right use the tangent ratio to solve for x

$tan41^o=\frac{opposite}{adjacent}=\frac{12}{x}$

Multiply both sides by $x$

x × $tan41^o=12$ ( divide both sides by $tan41^o$ )

x = ≈ ( nearest tenth )

Obtain an estimate for the following computation by rounding the numbers so that the resulting arithmetic can easily be performe

uranmaximum [27]

Answer:

Step-by-step explanation:

2915 can stay as it is; 15.458 should be rounded down to 15. Then we have

2915-15, or 2900 (which is a very reasonable estimate).
