Answer:
$2.64
Step-by-step explanation:
0.44 times 6.
Step-by-step explanation:
(b) If then
Note that cancel out so we get
Solving for we get
(c) I'm not sure what the problem is asking for but here goes. As r doubles, becomes
x+y = 47
x-y = 21
------------ add together
2x =68 divide by 2
x=34
x+y = 47
34+ y = 47
subtract 34 from each side
y = 13
the two numbers are 34 and 13
y = -13, 13
There are two answers because you are taking the square root of a number. If we go the other way, to check our work, (-13)^2 = 169 and (13)^2 = 169.
Hope this helps! :)
21.678 is the Answer because you need to comedian the numbers together
