Answer:
Step-by-step explanation:
5r + 2b = 14 (5 lbs of oranges and 2 lbs of bananas = $14)
3r + 6b = 18 (3 lbs of oranges and 6 lbs of bananas = $18)
Let's use the elimination method. Multiply the first equation by -3:
-15r - 6b = -42
3r + 6b = 18
-----------------
12r = 24
Divide by 12:
r = 2
Answer:
37
Step-by-step explanation:
37 can only be multiplied by 1 and 37. Because prime numbers cannot be multiplied by any whole number except 1 and itself, the answer must be 37.
Answer:
8, 15, 17
Step-by-step explanation:
The 2nd option. You know this by using this math formula: a^2 + b^2 = c^2. That is the formula to find a right triangle. So if you square 8 and 15 you get 64 and 225, and if you add them together you get 289, which is 17^2. Hope this helps! :)
Answer: The area of the square is 64 square inches and the area of the new rectangle is 60 square inches. The square's area is 4 inches larger than the rectangle.
Step-by-step explanation: If a side length of the square measures 8 inches, then its area can be calculated as follows;
Area = L x W
The length and the width both measure 8 inches (all sides of a square are equal in length).
Area = 8 x 8
Area = 64
Also, the the new rectangle is formed by increasing the width of the square by 2 inches (that is 8 + 2 = 10), and decreasing the length by 2 inches (that is 8 - 2 = 6). The area of the new rectangle is calculated as follows;
Area = L x W
Area = 10 x 6
Area = 60
Therefore the area of the square is 64 square inches and the area of the rectangle is 60 square inches. The area of the square is 4 inches larger than that of the rectangle.
An equation is a mathematical statement that two things are equal. It consists of two expressions, one on each side of an 'equals' sign.
