Answer:
x = -3/5
Step-by-step explanation:
y = 10x + 6
0 (- 6) = 10x + 6 (- 6)
-6/10 = 10x/10
-6/10 = x
-3/5 = x
18 is the least common denominator of all the fractions, so you can eliminate fractions by multiplying the equation by 18.
(4.5*18)x +((7/9)*18)x + (2 1/3)*18 + ((1/6)*18)x = (5 1/18)*18
81x +14x +42 +3x = 91 . . . . . simplify
Collect terms.
98x + 42 = 91
98x = 49 . . . . . . . . . subtract 42
x = 49/98 = 1/2
The solution is x = 1/2.

You can also do the arithmetic with mixed numbers and fractions. The usual methods apply.
(4.5 + 7/9 + 1/6)x + 2 1/3 = 5 1/18
(49/9)x + 7/3 = 91/18
(49/9)x = 49/18 . . . . . . . subtract 7/3
x = (9/49)(49/18) = 9/18 = 1/2 . . . . . multiply by 9/49
This can be a little more tedious than the method above, but it works and it will give you the right answer. A calculator that works with fractions can make this solution as easy as the other one.
Answer: 760 mm thick
Step-by-step explanation: Because 10 cubed equals 1000, just multiply .76 by 1000 and you get your answer.
Answer:
<u>168 </u>members are on the marching band but not part of the percussion.
Step-by-step explanation:
Given:
The high school marching band has 196 members,and 28 of them are a part of the percussion.
Now, to find the members on the marching band but not part of the percussion.
Total members of marching band = 196.
Members of them who part of percussion = 28.
So, to get the members of the marching band who are not the part of the percussion we subtract members of them who part of percussion from total members of marching band:
Therefore, 168 members are on the marching band but not part of the percussion.
