The product of 15 multiplied by 22 is 330. This can be calculated by multiplying the tens digits first (1 x 2 = 2) to get the tens place value, and then multiplying the ones digits (5 x 2 = 10) to get the ones place value. Combining these results (20 for the tens place and 10 for the ones place) gives us the final answer of 330.

The difference of two numbers is 15 five times the smaller is the same as 9 less than twice the larger find the number?
Call the numbers x and y (x>y) "The difference of two numbers is 15." x - y =15 "Five times the smaller is 9 less than twice the larger." 5y = 2x - 9 From the first equation, y = x-15 Substitute into the second: 5(x-15) = 2x - 9 expand: 5x - 75 = 2x - 9 collect terms: 5x - 2x = 75 - 9 simplify 3x = 66 x = 22 y = x-15 = 22-15 = 7 (x,y) = (22, 7)
One number is 2 more than 3 times another. Their sum is 22?
5 + 17 = 22 5 x 3 = 15 15 + 2 = 17
What is 22 divided by 15?
1.4667
What is the sum of two numbers is 37 and their difference is 7 find the numbers?
Answer:22, 15.Solution:Suppose the first number is x, second one is y, then x + y = 37, x - y = 7.adding these equations:x + y = 37+x - y = 7_____________2 x + 0 = 44x = 44/2 = 22now substitute in first equation:22 + y = 37y = 37 - 22y = 15so the numbers are: 22 and 15.
What is the area of a room that is 15ft by 22ft?
The area of the floor is (15 x 22) = 330 square feet. The area of the ceiling is also (15 x 22) = 330 square feet. In order to calculate the area of the walls, we'd have to know the height of the ceiling.
