6 and 4
Avreage = Sum/number of values So 10 = sum/2 Multiply both sides by 2: 20 = sum
The sum of the first 10 even numbers is 110.
The units digit of a two digit number exceeds twice the tens digit by 1. Find the number if the sum of its digits is 10.
The sum of their squares is 10.
To find the sum as a product of the greatest common factor of two numbers basically indicates that you need to use the distributive property. For example, 44+40=4(10+11). It's just how many times the GCF goes into the factors. In this case 4 goes into 40, 10 times and 4 goes into 44, 11 times.
They are: 14 and 4
4 and 6.
10 and 2
The prime factors of 30 are: 2 + 3 + 5 = 10
Add the numbers together (sum) and divide by two (average). SUM: 2 + 8 = 10 AVG: 10 / 2 = 5
2 and 10. 2*10=20 2+10=12
Factors for 20 are: 1, 2, 4, 5, 10, 20 Prime Factors: 2, 5 sum of prime factors = 2 + 5 = 7
Two consecutive integers whose sum is 19 is 10 & 9; 10+9 = 19.
4nd 9.
21 and 32
The factors of 10 are 1, 2, 5, and 10. Among these, the pairs whose sum is 7 are 1 and 6, and 2 and 5. These pairs are factors of 10 as they divide evenly into 10 without leaving a remainder.
