6/8 because she painted half of her room in 3/4 of an hour and add half of that and you get 6/8! Hope this helps! Im not very good at math so don't judge me if its wrong...
Let's solve for y.
4x+7y=28
Add -4x to both sides.
4x+7y+−4x=28+−4x
7y=−4x+28
Divide both sides by 7.
7y/7=−4x+28/7
y=−4/7x+4
Two lines that cross each other have each pair of angles the same.
2x+6=96 --> x=45
Paul has 70 Total sport cards.
3 (Baseball) + 3 (Football) + 4 (Baseball) = 10 (Total cards per pile) × 7 (Total Piles) = 70 (Total Cards
3+3+4=10×7=70
(All shown work is this ^)
If I'm right please help me out by following me. Thank you for your wonderful question~!
I'm pretty sure the answer is D. because I don't think anyone would want to take their total meal cost and then multiply it by their tip to make it even larger. You would just add the tip to the meal cost.
