Divide 24 by 6 because that is how many numbers are on the cube which would equal 4
Then multiply 4 and 2 because that's how many possibilities there are of rolling a number less than 4 and is even and the solution is 8
Hi there! You are subtracting a negative number, which is basically the same thing as adding, because two negatives make a positive. B and C is out, because they do not fit the expression. You are actually adding both numbers and anytime you have to subtract a negative number, you add. When you do basic math, 4 + 7 is 11. Both numbers are negative and D does not work, because you're adding from a negative number. The only answer choice that has the expression is A. The answer is A.
<span>20 - 2 * 3^2
Remember PEMDAS.
Parentheses
Exponents
Multiplication/Division
</span>Addition/Subtraction
There are no parentheses, but there is an exponent. So first you must do 3^2.
<span>20 - 2 * (3*3)
</span>20 - 2 * 9
Next is multiplication/division. Multiply -2 by 9.
20 - 2 * 9
20 - 18
Lastly, you subtract.
20 - 18
2
The answer is 2.
