Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
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.
The closest answer is 95 square inches. Here is why. You can find the area of the rectangle by multiplying the length by the width. This would be 15 x 5 = 75 square inches. The area of the whole circle that is created when you put both halves together would be found by multiplying 3.14 x 2.5 in (the radius) x 2.5 in. This answer is about 20 square inches. The combined area is approximately 95 square inches.
