Step-by-step explanation:
To add fractions, find the LCD and then combine.
5(2x +8) = -8x + 4
Use distributive property:
10x +40 = -8x + 4
Subtract 40 from each side:
10x = -8x -36
Add 8x to each side:
18x = -36
Divide both sides by 18:
x = -36 / 18
x = -2
The number is -2
( 2(x^2) + 6x + 6 ) * ( 3x - 2 )
= 6(x^3) + 14(x^2) + 6x - 12
so the answer is D
Answer:
Eggs 2 3 4
Milk 6 9 12
Ratio 3/1 3/1 3/1
Step-by-step explanation:
Look at the second column with 2 eggs and 6 cups of milk.
6 cups milk and 2 eggs. The ratio of the number of cups of milk to number of eggs is 6/2, which is the same as 3/1 in the second column. The number of cups of milk is always 3 times the number of eggs.
If you know the number of eggs, multiply by 3 to get the number of cups of milk. 3 * 3 = 9 in the third column.
If you know the number of cups of milk, divide by 3 to get the number of eggs. 12/3 = 4 in the fourth column.
Eggs 2 3 4
Milk 6 9 12
Ratio 3/1 3/1 3/1
Answer:
17
Step-by-step explanation:
So, this is a percentage problem.
Start off by finding how many students 0.28% is:
If 100% = 5780
0.01% = 0.578
Now:
0.01% = 0.578
0.28% = 16.184
The exercise tells you to round for a whole person, so 16.184 turns 17
And that's the answer!
