five times the sum of a number and 8 is -15.
5
the sum of 8 and 4 times a number is 36
8(5+4)+7 = 79
The sum of 8 and 5 is 13. There is then no number with which to calculate its product.
This is simple algebra. Let the unknown number be n. Then the sum of this number and 8 = n + 8.
(3a-8) + 5x(a)
5
The sum of two times a number (let's call it ( x )) and five is expressed as ( 2x + 5 ). The phrase "at 8 to 6 times the number" can be interpreted as ( 8 - 6x ). Therefore, the complete expression for the sum is ( 2x + 5 + (8 - 6x) ). Simplifying this yields ( -4x + 13 ).
8(5 + x), or 8x + 40.
the sum of 8 and 4 times a number is 36
8(5+4)+7 = 79
First, write an equation: 8(n+5) Next, distribute: 8n+40 Thats it. (Normally, there would be an = sign to solve for n. For example, you would have 8n+40= 64, then 8n would equal 24, and n would be 3.)
5*n + (n - 8) = 5n + n - 8 = 6n - 8
The sum of 8 and 5 is 13. There is then no number with which to calculate its product.
This is simple algebra. Let the unknown number be n. Then the sum of this number and 8 = n + 8.
5(x+3)+8
Not necessarily. If the number is 0, then the sum of 8 times the number and -192 is -192.
