Ethan plotted points E, F, G, H, and I on a number line, as shown below. Which two points that Ethan plotted represent numbers t
nirvana33 [79]

Answer:

F and H

Step-by-step explanation:

From the image attached, the location of the points are E = -9, F = -6, G = -2, H = 6, I = 8. The law of additive inverse states that for a number a, its additive inverse is a number that when added to a equals to zero. This number is usually opposite in sign to a and of the same magnitude i.e -a. The law is given as:

a + (-a) = 0

From the points, F is the additive inverse of H, hence:

F + H = 0

6 + (-6) = 6 - 6 = 0

Hence the two points are F ad H

if one inch represents 14 feet how many inches would you use to make a scale drawing of a building that is 199 feet
gayaneshka [121]

Answer:

14.2 inches

Step-by-step explanation:

Given

1 inch = 14 feet

Required

Find the equivalent of 199 feet

Write out the given expression;

1 inch = 14 feet

Divide both sides by 14

\frac{1\ inch}{14} = \frac{14\ feet}{14}

\frac{1\ inch}{14} = 1\ foot

1 foot = \frac{1}{14}inch

Let x represent the equivalent of 199 feet in inches;

Such that:

x = 199\ feet

x = 199 * 1 foot

Substitute 1 foot = \frac{1}{14}inch

x = 199 * 1 foot becomes

x = 199 * \frac{1}{14} inch

x = \frac{199}{14} inch

x = 14.2142857143 inch

<em>x = 14.2 inches (Approximated)</em>
