Solve each equation check your solution? 1-14?

1.) t+7=12

2.) h-3=8

3.) 8=b-9

4.) k-4=-14

5.) m+9=-7

6.) y-10=-3

7.) -14=2+d

8.) 15+n=10

9.) -8=r-6

10.) 11=w-5

11.) -9=g+9

12.) 12+c=16

13.) GEOMETRY: Two angles are supplementary if the sum of their measures is 18- degrees the two angles shown are supplementary. Write and solve an equation to find the measure of r

14.) ARCHITECTURE: The Sears Tower in Chicago was the tallest building in the world when it was completed. Twenty-three years later, a taller building was completed in 1996 on taiwan. Write an equation to find the year that the Sears Tower was completed.

    1)

    t + 7 = 12

    subtract 7 from both sides:

    t = 5

    2)

    h - 3 = 8

    add 3 to each side:

    h = 11

    3)

    8 = b - 9

    add 9 to both sides:

    b = 17

    4)

    k - 4 = -14

    add 4 to both sides:

    k = -10

    5)

    m + 9 = -7

    subtract 9 from both sides:

    m = -16

    6)

    y - 10 = -3

    add 10 to both sides:

    y = 7

    7)

    -14 = 2 + d

    subtract 2 from both sides:

    d = -16

    8)

    15 + n = 10

    subtract 15 from both sides:

    n = -5

    9)

    -8 = r - 6

    add 6 to both sides:

    r = -2

    10)

    11 = w - 5

    add 5 to both sides:

    w = 16

    11)

    -9 = g + 9

    subtract 9 from both sides:

    g = -18

    12)

    12 + c = 16

    subtract 12 from both sides:

    c = 4

    13)

    r + s = 180

    14)

    1996 - 23 = 1973

Then the inhabitants of Africa is 4x (4 cases Greece). Africa's inhabitants is given, that's 40 4 mil. So, 4x = 40 4, x = 40 4/4, x = 11. X is Greece's inhabitants so this is 11 million.
