what do you need help with
Step-by-step explanation:
Well, you can’t add them because 15 has a m and 35 doesn’t have a variable sooo? What are the answer choices?
Let the second no. be x
-3x = 21 → x = 21/-3 → x = -7
Answer:
36
Step-by-step explanation:
Hullo :D
If you're having trouble understanding, you might not understand the Order of Operations.
P - Parenthesis. Solve what's inside the Parenthesis first
E - Exponents. Solve for Exponents second.
M - Multiply. Multiply numbers third. (left - to - right with division, too)
D - Divide. Divide fourth. It is interchangeable with multiplication, as well.
A - Addition. Add fifth.
S - Subtract sixth. It is interchangeable with Addition, as well.
With that in mind, all we need to do is identify these types in the equation:
(6+3)4
We see parenthesis. We will solve them first according to the Order of Operations:
6 + 3 = 9.
(9)4
We see multiplication. We solve them next according to the Order of Operations:
9 × 4 = 36.
Thus, the final answer is
.
Hope this helps!
