7y-3°=3y+13°
7y-3y= 13°+3°
4y= 16°
y=4°
Substitute y
7(4)-3°= 25°
3(4)+13=25°
180°-25°-25°=130°
2(2x+3)°+130°=180°
4x+136°=180°
4x=44°
x=11°
Answer:
Tom has 70 cards, and Harry has 28 cards.
Step-by-step explanation:
Let h = number of cards Harry has.
Then the number of cards Tom has is 2 1/2 * h = 2.5h.
Together they have 2.5h + h = 3.5h number of cards.
Together they have 98 cards.
3.5h = 98
h = 98/3.5
h = 28
Harry has 28 cards.
Tom has 2.5h = 2.5 * 28 = 70
Answer: Tom has 70 cards, and Harry has 28 cards.

Answer:
I think that 1 is the answer, thats what came out on my calculator.
Step-by-step explanation:
64 x 100 = 6400
11 x x = 11x
I’ll solve this out for you
11x = 6400
Divide 11 from both sides
x = 581.8
Hope this helps!
