-87/3 = -29 therefore -28 + -29 + -30 = -87
The total sum is: 25+52+10 = 87
27,29,31
85, 86, 87
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
To work this out you have to do the sum of 87 divided by 900% The answer would be 96%
87+42+78 = 207
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
