Answer:
x = 12
y = 13
Step-by-step explanation:
Let's assume the two numbers as x and y.
The sum of the two numbers is 25
So,
The product of the two numbers is 156
- xy = 156
- x(25 - x) = 156
- 25x - x² = 156
- x² - 25x + 156 = 0
- x² - 13x - 12x - 156 = 0
- (x - 12) • (x - 13) = 0
- x - 13 = 0
- x = 13
- x - 12 = 0
- x = 12
Hence, the two numbers are 13 and 12.
Answer:
Range: 13 and 15 Mean: 247 and 286
Step-by-step explanation:
Yes, 3/4 is bigger than 3/5.
One way you can verify this is by drawing a bar model, and cut it into four. Color in three pieces.
Then, draw another bar model the same size as the first one, and cut it into five pieces.
Color in three pieces.
You can see that 3/4 has more shaded in area than 3/5.
Another way you can do this is by dividing the numerator by the denominator for both fractions.
Hope this helped.
