-4x - 7 = 16 -4x = 16 + 7 -4x = 23 x = -23/4 x = -5.75 Check: -4(-5.74) - 7 = 16 23 - 7 = 16 16 = 16
7/16 x 4/3 x 1/2=7/16 x 4/6=[ 28/96 ]=[7/24] (reduced)
24 = 8 + 16 16 = 4 x 4 4 = 7 - 3 Answer: 24 = 8 + [4 x (7 - 3)]
(4/5)/(16/7) = (4/5)x(7/16) = 28/80 = 7/20
7/16 x 4/3 x 1/2 = 7/24
-4x - 7 = 16 -4x = 16 + 7 -4x = 23 x = -23/4 x = -5.75 Check: -4(-5.74) - 7 = 16 23 - 7 = 16 16 = 16
As 112 = 16 x 7 then we can write :- √112 = √(16 x 7) = √16 x √7 = 4√7 The value for √7 needs to be obtained via a calculator Then √112 = 4√7 = 4 x 2.64575 = 10.58300
7 hundreds, 16 tens 4 ones is 7 x 100 + 16 x 10 + 4 x 1 = 700 + 160 + 4 = 864.
(21 + 7) x (9-4) - 16 (28) x (5) - 16 140 - 16 124
49/16 = (7^2)/(4^2) = (7/4)^2 = ((4/7)^-1)^2 = (4/7)^-2 Thus as (4/7)^2 = 49/16 and 49/16 = (4/7)^-2 (4/7)^x = (4/7)^-2 Therefore x = -2.
7/16 x 4/3 x 1/2=7/16 x 4/6=[ 28/96 ]=[7/24] (reduced)
2x + 7 + 2x = 23 4x + 7 = 23 4x = 16 x = 16/4 x = 4
24 = 8 + 16 16 = 4 x 4 4 = 7 - 3 Answer: 24 = 8 + [4 x (7 - 3)]
(4/5)/(16/7) = (4/5)x(7/16) = 28/80 = 7/20
(4/7) x (4/9) = (4 x 4) / (7 x 9) = 16/63. This fraction is in lowest terms.
(4/7)^2 x (7)^4 = (4)^2 x (7)^2 = 16 x 49 = 784
7/16 x 4/3 x 1/2 = 7/24
