Answer:
3.06
Step-by-step explanation:
3 is in the ones place, then theres the decimal, the tenths place, and the hundredths place. When rounding, you must make the number larger when its 5 or over. So the answer is 3.06
4 1/2 = 9 / 2 ;
Then, ( 9 / 2 ) ÷ ( 3 / 4 ) = ( 9 / 2 ) × ( 4 / 3 ) = ( 36 / 6 ) = 6 ;
Finally, ( 4 1/2 ) × 6 = ( 9 / 2 ) x 6 = 54 / 6 = 9 ;
y = 9.
Answer:
The coefficient of x is 2.
Step-by-step explanation:
1) Add the numbers
7y + 4x + 4 - 2x + 8
7y + 4x + 12 - 2x
2) Combine like terms
7y + 4x + 12 - 2x
7y + 2x + 12
3) Rearrange items
7y + 2x + 12
2x + 7y + 12
So the width can be written as W=3L-6. (L is length and W is width). The maximum the width could be is 45mm, so try to use 45mm in place of W. 45=3L-6. Add 6 to both sides and you get 51=3L. Divide both sides by 3 and you get 17=L, where L is the length.
