8(2x – 14) + 13 = 4x – 27
Juliette [100K]
8 (2x - 14) + 13 = 4x -27

distribute 8 through the parentheses

16x - 112 + 13 = 4x - 27

combine like terms

16x - 99 = 4x -27

subtract 4x from each side

12x - 99 = -27

add 99 to each side

12x = 72

divide each side by 12

x = 6

About 7/10 of the surface of the earth is covered with water. Express this as an equivalent fraction with 100 as the denominator
larisa [96]

Answer:

70/100

Step-by-step explanation:

Surface of the earth covered with water = 7/10

Equivalent fraction of 7/10 with 100 as the denominator = 70/100

This means 70% of the earth surface is covered with water

Percentage covered with land = Total percentage - percentage covered with water

= 100/100 - 70/100

= 100-70/100

= 30/100

Percentage covered with land = 30%
