Answer: -2
Step-by-step explanation: As our first step, we simplify inside the absolute value. 7 - 9 is -2 so we have -|-2|.
A common mistake at this point in the problem is to change the minus a negative to plus a positive but don't fall into this trap.
We must ignore the negative outside the absolute value until our very last step in this problem.
So we take the absolute value of -2 which is 2 and we have -(2) or -2.
Notice that I used parentheses around the 2 as it comes out of the absolute value.
Answer:
30 cm
Step-by-step explanation:
Hello!
To find the volume of a rectangular prism you use the equation
V = lhw
v is volume
l is length
h is height
w is width
Put in the values you know
180 = 6 * 5 * w
Divide both sides by 6
30 = 5 * w
Divide both sides by 5
6 = w
Answer is 6cm
Hope this helps!
You solve for a variable in an equation by taking the variable to one side of the equation and other terms to the other side of the equation using arithmetic properties.
