Answer:
Step-by-step explanation:
90 degrees
x + y = 180
x = y
x + x = 180
2x = 180
x = 180/2
x = 90
Both the angle and its supplement = 90
Hello.
The answer is: 17.25
To get the answer
Hockey cards: x= 6y
baseball cards: x + y = 525
if u add them both you get 75 and 450 then times by 6
= 450 * .03+ 75 * .05
Have a nice day
9 because it’s skip counting by 3 and 2
You’d set up a proportion. I did 25/15=7x-40/18.
Then you would cross multiply to get 15(7x-40)=450
Distribute the 15.
105x-600=450
Add 600 to both sides, so the -600 cancels out.
Then you’re left with 105x=1050
Divide both sides by 105 and you get x=10
