Answer:
Parenthesis, Exponents (& roots), Multiplication, Division, Addition, Subtraction.
This is the order you use when you need PEMDAS. For example, in this question:
(2 * 3) + 5(3)
First, you solve the parenthesis: 2 * 3 = 6
Next, you solve for multiplication: 5(3) = 15
Finally, you add: 6 + 15 = 21

Distance=speed x time
speed=68 miles/hour
time=4 hours
Distance=(68 miles/hour)(4 hours)=272 miles.
Answer: he traveled 272 miles.
Answer:
2 solutions
Step-by-step explanation:
We are given the equations of f(x) and g(x).
To find f(x) = g(x), we just let those two equations equal each other
Group all like terms,
Factorise,
Therefore, there are two solutions
Hope this helped!!
Answer:
The answer is B
Step-by-step explanation:
Answer:
x = 7
y = 0
Step-by-step explanation:
→To solve this, you can use the elimination method. To do this, you must have one set of variables that can cancel each other out. In the problem given, we already have positive 4x and -4x, making them cancel out:
4x + 9y = 28
-4x - y = -28
__________
8y = 0
y = 0
<u>→Plug in 0 for y, into an equation:</u>
-4x - 0 = -28
-4x = -28
x = 7
