No. 43 is a prime number. It has no other factors besides ' 1 ' and itself.
Answer:
-5x + 7
Step-by-step explanation:
-4x - 2y = -2
x - 2y = 9
First, you're going to subtract the equations from each other.
(-4x - 2y = -2) - (x - 2y = 9)
Next, you need to get rid of the equal sign in both equations.
(-4x - 2y = -2) - (x - 2y = 9)
+2 +2 -9 -9
After you get rid of the equal signs, you will distribute the sign to the equation and then subtract everything.
-4x - 2y + 2 - x + 2y + 9
Now, combine the like terms.
(-4x -x) + (-2y + 2y) + (2 + 9)
Finally, calculate the terms and solve.
-5x + 7
Answer:
Step-by-step explanation:
Figuring out based on $10.00 per hour rental fee.
you would take the number of full hours and multiply by the fee.
5 hours x $10 = $50
for the leftover .5 hours (which is half an hour) you would take the $10 hourly fee and divide it in half.
$10 ÷ 2 = $5 per half hour
$5 x 1 (half hour) = $5
Now add up the total for the 5 hours and the total for the half hour and that is your total cost.
The expressions are:
- (5x² - 6)/ 2
- 5x² - 18/2
- 5x² -6 /2
<h3 /><h3>What is expression?</h3>
A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:
- An absolute numerical number is referred to as a constant.
- Variable: A symbol without a set value is referred to as a variable.
- Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.
- Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.
Given:
15 x squared minus 18 end quantity over 6.
= 15x² - 18 / 6
= 3(5x² - 6)/ 6
= (5x² - 6)/ 2
and, 5 x squared minus 18 end quantity over 2
= 5x² - 18/2
and, 5 x squared minus 6 end quantity over 2
= 5x² -6 /2
