The estimate for the square root is 4.5.
Answer: 23x > 115
Step-by-step explanation:
And for "a number" we can use a variable for it
x (it can be any variable like a or b)
The product of 23 and a number implies multiplication
23x
For "greater than" use a greater than symbol
23x>
So the word sentence as an inequality is
23x>115
Answer:
Answer is C
Step-by-step explanation:
(x + 6)(x + 2)
Well, we need to divide $36.25 by 12.5. This will give us the per gallon price. So 36.25/12.5=2.90.
So regular gasoline is $2.90 a gallon
So, now we know this, if we add 14¢ to 2.90, we get $3.04. Now, we multiply 3.04 by 12.5=38. So, 12 and a half gallons of premium gas costs $38
