Answer:

A) X = 8

B) X = 4.3 or 13/3

Step-by-step explanation:

A) 5x - 10 = 30

(add ten to both sides)

    5x = 40

(divide by 5 on both sides)

    <u>x = 8</u>

<u></u>

B) 3x + 8 = 21

(subtract 8 to both sides)

    3x = 13

(divide by 3 on both sides)

    <u>x = 4.3 or 13/3</u>

Hope this helped!

∠F and ∠G are supplementary angles. If m∠F is two less than six times the measure of ∠G, find the measures of both angles
Mnenie [13.5K]

Answer:

∠ G = 26°, ∠ F = 154°

Step-by-step explanation:

Express ∠ F in terms of ∠ G, that is

F = 6G - 2

and since the angles are supplementary, then

G + 6G - 2 = 180, that is

7G - 2 = 180 ( add 2 to both sides )

7G = 182 ( divide both sides by 7 )

G = 26

Thus

∠ G = 26° and ∠ F = 6(26) - 2 = 156 - 2 = 154°

Eddi Din [679]

Answer:

\boxed{13} pages

Step-by-step explanation:

Divide the total number of pages by 5 to get how many sets of every 5 pages will contain 2/3 of a page of advertisements.

\frac{98}{5} = 19.6

Multiply this value by \frac{2}{3} to get the total number of pages.

19.6 * \frac{2}{3} \approxeq 13 pages
