Answer:
Step-by-step explanation:First you cross out 192 and add it to 58. Then you cross out 4x and subtract it from -6x which gets you -10x. Your equation should end up being -10x= 250 and your final answer will be -25
Answer:
b=3
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
x + y = 24 where x and y are the 2 parts of diagonal Other diagonal wil be smaller that 24.
x^2 + z^2 = 13^2
y^2 + z^2 = 20^2 where z = 0.5 * length of smaller diagonal)
form last 2 equations
y^2 - x^2 = 20^2 - 13^2 = 231
now y = 24-x so we have
(24 - x)^2 - x^2 = 231
576 - 48x = 231
48x = 345
x = 7.1875
z^2 = 13^2 - 7.1875^2 = 117.34
z = 1.83
so smaller diagonal = 21.66 cm
looks like its the third choice.
I believe it is a. $331.52. Hope this helps :)
The correct answer would be #3
