a digital scale measures weight to the nearest 0.2 pound. which measurement shows an appropriate level of precison for the scale
nadezda [96]

Answer:

130.4 pounds

Step-by-step explanation:

The digital scale is measuring weight to the nearest 0.2 pounds, so basically the digital scale would show you the weight of an object that is a multiple of 0.2.

Talking about precision, precision tells us how accurate is the measured value or how close is the measured value to the actual value.

Here, scale is measuring to the nearest 0.2 pounds, so out of the given values the measurement that shows an appropriate level of precision for the scale is 130.4 pounds.

Rewrite in a simpler equivalent form and solve
AveGali [126]

Given:

The equation is

\dfrac{3x}{7}+\dfrac{2}{7}=2

To find:

The simpler equivalent form and solve the given equation.

Solution:

We have,

\dfrac{3x}{7}+\dfrac{2}{7}=2

It can be written as

\dfrac{3x+2}{7}=2

Multiply both sides by 7.

3x+2=14

3x=14-2

3x=12

Divide both sides by 3.

x=\dfrac{12}{3}

x=4

Therefore, the simpler equivalent form of the given equation is 3x+2=14 and the solution is x=4.

Point M is on line segment LN. Given LN = 9, MN = 4x, and LM=5x
andrew-mc [135]

Answer:

MN = 4

Step-by-step explanation:

Given that L, M, N are collinear,

LN = 9,

MN = 4x

LM = 5x

Required:

Length of MN

SOLUTION:

To calculate the numerical length of MN, we need to find the value of x.

To find the value of x, generate an equation to solve for x as follows:

LM + MN = LN (segment addition postulate)

5x + 4x = 9 (substitution)

Solve for x

9x = 9

Divide both sides by 9

\frac{9x}{9} = \frac{9}{9}

x = 1

MN = 4x

plug in the value of x

MN = 4(1) = 4
