There are 10/9 cups of cinnamon in 1 pound of spice mix
and if you wanna convert the improper fraction to a mixed number it will be 11/9
Answer:
2
x + 3y − 6
Step-by-step explanation:
If you simplify you should get 2
x + 3y − 6
The average of 4, 9, 16, 25 and x is 2x means that;
(4+9+16+25+x)/5=2x
Multiply both side by 5
5(54+x)/5=2x(5)
54+x=10x
Subtract x to both side
54+x-x=10x-x
54=9x
Divided 9 to both side
54/9=9x/9
x=6
Check:
Substitute x with 6
(4+9+16+25+x)/5=2x
(4+9+16+25+6)/5=2(6)
60/5=12
12=12; so x=6 which marks B as the correct answer. Have a nice day!
