-87/3 = -29 therefore -28 + -29 + -30 = -87
The total sum is: 25+52+10 = 87
85, 86, 87
27,29,31
There are no real numbers with the sum of 4 and a product of -477. The factors of -477 are (1,-477), (3, -159) and (9, -53). The negatives can be switched to the other numbers in those pairs of factors.
87% of 380=330,6! Remember % means as a fraction of 100,of means multiply Therefore (87/100 x380) =330,6.)
The total sum is 87

Since the sum of the proper factors of 87 is only 33, 87 is not an abundant number.
The sum is 181
87+42+78 = 207
To work this out you have to do the sum of 87 divided by 900% The answer would be 96%
They are: 27+29+31 = 87
To find the sum of the numbers between 43 and 87 inclusive, we need to add up all the numbers between them, including 43 and 87. There are a couple of ways to do this, but one common method is to use the formula for the sum of an arithmetic sequence: S = (n/2)(a + b) where S is the sum, n is the number of terms, a is the first term, and b is the last term. In this case, we want to find the sum of the numbers between 43 and 87, so: a = 43 b = 87 To find the number of terms, we need to count how many numbers are between 43 and 87, inclusive. There are 87 - 43 + 1 = 45 numbers. Therefore, the sum is: S = (45/2)(43 + 87) = 2025 So the sum of the numbers between 43 and 87 inclusive is 2025.
x2 + x = 380 x2 + x - 380 = 0 (x + 20)(x - 19) x = 19, -20
-87/3 = -29 therefore -28 + -29 + -30 = -87
