4x - 7
To express "7 times a number increased by 4" mathematically, you would write it as 7x + 4, where x represents the unknown number. This expression indicates that you multiply the number by 7 and then add 4 to the result. So, if the number is 5, the expression would be 7(5) + 4 = 35 + 4 = 39.
Let the number be x and so the expression is: 4x -7
15 less than 7 times a number is:15-7n
4/7
18 is a solution to the equation 4 plus 7 times a number where the result is 9 times that number.
To write 7 less than 2 times a number, you would first multiply the number by 2. This gives you 2x. Then, you would subtract 7 from the result of 2 times the number: 2x - 7. This expression represents the value of 7 less than 2 times a number.
The equation can be written as -7x - 4 = 13 - 6x, where "x" represents the unknown number.
Let the unknown number be x: 4x-2 = -7 4x = -7+2 4x = -5 x = -1.25
The number of times 7 can go into 11 is 1, with a remainder of 4. This is because 7 multiplied by 1 is 7, which is the largest multiple of 7 that is less than 11. The remainder is the difference between 11 and the product of 7 and the whole number of times it fits into 11.
4x-6=22, 4x=28, 4/4(x)=28/4, x=7. That is how you get the answer to be 7
Any number less than 3.
