-8a+3=4a+27 subtract 27 from both sides add 8a to both sides
-24 = 12a divide both sides by 11
-24/12 = -2 = a
4 ( y + 7) = 4y + 28 ...... 8(x + 2) = 8x + 16
If you want to multiply these, we have
(4y + 28) (8x + 16) = 32xy + 64y + 224x + 448
18 +1/3 yards = 55ft 1 + 1/4 ft = 1.25 ft
So
55 / 1.25 = 44 / 1 [ or, 44 : 1 ]
75 / 500 = 15 / 100 = 15%
Area of a square = side squared ......so.......
8100 = s^2 take the root of both sides
90 ft = side
-1.6641 move the decimal two places to the right and add a % sign
-166.41 %
(6b+3)^20
The fifth term will be
C(20, 4) * (6b)^16 * (3)^4 =
4845 * 2821109907456 * b^16 * 81 =
1107130477631569920 b^16
Oops !!!!..... I made a slight error....I'll go back and edit it....sorry!!!!
OK.......got it......
The area = 2 pi *r * h = 2pi (6.2) (2) = about 78m^2
(7*(7-6+2)^2)-6 = [ perform all the operations in the innermost parentheses, first ]
(7*(1 + 2)^2) - 6 =
(7* (3)^2) - 6 = [ evaluate the exponent ]
(7 * 9) - 6 = [multiply within the parentheses ]
63 - 6 =
57
