Q: The sum of 2 times a number and 5 times the number?

Write your answer...

Let N represent the 'number'. It looks like the first phrase would be expressed as 2(N + 5) which expands to 2N + 10, while the second expression would be 2N + 5, which is not the same.Notice that the first one is 2 times the sum, while the second is 2 times a number.

The number is 45. The sum of its digits i.e. 4+5=9 Five times the sum of its digits i.e. 5 times 9 which is 45

because the number are the same /example2 times 3 equals 6. 3 times 2 equals 6

five times the sum of a number and 8 is -15.

5x + 6

The sum of 3 and a number, equaling 5, (if you want to know what the number is...) is 2 3+2=5

Let the number be x4x-3(x+2)=54x-3x-6=5x=11

Five times the sum of 6 and a number is 2 more than the numberWrite the equation5(6 + x) - 2 = x30 + 5x - 2 = x5x + 28 = x4x = -28x = -7Check: 5 (6 + (-7)) - 2 = -75(-1) - 2 = -7

2(y + 5)

They are 7 and 5.

To multiply a sum by a number,multiply each addend of the sum by the number outside the parentheses.For any numbers a, b, and c, a(b+c) = ab + ac and a(b-c) = ab - ac.Example: 2(5-3)= (2 times* 5) - (2 times* 3). Times*_multiply

( 5 + 3x )

5(x + 1/2) = 5x + 5/2

2 *5y

It is the sum of the whole number part and the fractional part. eg 5 2/3 = 5 + 2/3

5

Let: x= the number2x+5=102x=6x=3therefore: 3 is the number

5+3x

30/5 = 6 so x - 2 = 6 so x = 8

5 is the sum. 2 and 3 are the addends.

Statement:The sum of three times of a number and five.Assumption:Let us take the number be x.So, Three times the number = 3x.Equation: 3x+5

5 and 2

That would be an addition problem such as 2+3=5 5 would be the sum.

The number is 54. The sum of its digits is 5 + 4 = 9. 54/9 = 6.
