I’m going to try to answer these to the best of my ability.
1. Plane D
2. Plane C
3. AB
4. No
5. I don’t believe so because it doesn’t look like C is on the same plane as a AB and D.
6. I think so, yes! Collinear means that they are on the same line, and it looks like if you put a line between those two to connect them, they would connect perfectly!
7. B possibly? Because it looks like B, C, and D are all collinear and that they would pass through a straight line. A doesn’t look like it’s collinear with the rest of them.
8. No
9. Yes
10. Yes
I’m sorry if any of those are wrong, but I did make sure to try and put some explanations for some of them so you saw why I gave the answer that I gave! I hope that helped and like I said, I’m sorry if any of them are wrong, I tried my best!
Let x represent milk chocolate bar
y represent creamy nougat bars
3x+4y=4.25
6x+4y=6.5
6x+4y=6.5
-
3x+4y=4.25
=
3x=2.25
x=$0.75
y=$0.5. As a result, one milk chocolate bar costs $0.75 and one creamy nougat bar costs $0.5. Hope it help!
Step-by-step explanation:
"markup" contains "up". so, the price goes "up". this is actually increasing the price (e.g. by calculating the profit margin of selling an item on top of the cost of buying the item from the manufacturer).
"markdown" contains "down". so, the price goes "down". e.g. with discounts.
here we have a markup. it is 150%.
that means the price goes up by 150% compared to the original cost.
so, the computer game costs in the store
the original cost + 1.5× original costs
25 + 1.5×25 = 2.5×25 = $62.50
Divide 6 by 3, giving you 7m=2
Divide 2 by 7, giving you m=2/7
