For the expression 4x-7, what is the smallest whole number value for x that gives a result that is more than 150?
4x - 7 > 150
To solve for x, add 7 to both sides and then divide by 4.
I don't understand where to put the seven on the 4x-7 side
To find the smallest whole number value for x that gives a result greater than 150 for the expression 4x-7, we can set up an inequality and solve for x.
The expression 4x - 7 should be greater than 150, so we can write the inequality as:
4x - 7 > 150
To isolate the variable x, we need to get rid of the constant term (-7) on the left side of the inequality. We can do this by adding 7 to both sides:
4x > 150 + 7
4x > 157
Next, divide both sides of the inequality by 4 to solve for x:
x > 157/4
The smallest whole number value for x that makes the expression 4x - 7 greater than 150 is the smallest integer greater than 157/4. Since we're looking for a whole number, we round up to the nearest whole number, which is 40.
Therefore, the smallest whole number value for x that gives a result greater than 150 for the expression 4x - 7 is x = 40.
