This is an improper. Perhaps you can fix it, so that I can assist you with it? I apologise.
Yes, if there's nothing separating the two variables (like "+" or "-") then you'd multiply them.
For example, ab means you multiply a times b.
It would be $180.49 because
1. The cost of the board is 128.92
2. you need to mark up 40%, which is 0.4
3. 128.92* 0.4 = 51.57 , this is the amount you need to mark up by
4. then you add the amount you need to mark up by to the cost of the board: 51.57+ 128.92 = $180.49.
Divide 21 by 8. and then whatever the reminder comes will go as the whole number
and the reminder will be the numerator and the number 8 will be the denominator.
the answer is 2 5/8
2 is the whole number, 5 is the numerator and 8 is the denominator
Answer:
-1/4
Step-by-step explanation:
For this equation, first divide both sides by 1.2, to get x+4y=15. Then, subtract x from both sides. Now, with 4y=-x+15, divide by 4. You should get y=-1/4x+15/4 (15/4=3 3/4 or 3.75). The formula y=kx=b, where k is slope, means the slope is -1/4.
