Well, let's write it out, shall we?
6c2-5d+8
Now plug in the numbers.
6(5^2)2-5(4)+8
Now simplify using PEMDAS
Parentheses
Exponents
Multiplication
Division
Addition and Subtraction (They go together go from left to right in the equation)
5^2= 5*5 = 25
6 * 25 = 150
150 * 2 = 300
5 * 4 = 20
Rewrite the equation.
150-20+8
Use PEMDAS again ( refer to the previous mentioning)
150 - 20 = 130
130 + 8 = 138
I hope I am reading the problem right: The price of a mountain bike increased by 20% in the past year. The value is $150. What was the value of the mountain bike last year?
Let's simplify this. One year, there was this radical mountain bike that used to have an unsaid price, <em>x. </em>That year, that price of x increased by 20% more than it was before, or <em>120% times the original value</em>. Because of that, it's now $150.
We can equation this.
1.20x = 150
x = 150/1.2
x = 125
The bike, I believe, cost $125 last year. Hope this helps!
The equation used would be:
4m + 2 = 30
where the answer would be 7.
The First group i.e 1-10 include more prime numbers .(2,3,5,7,1)
- Because it has the basic inputs of every number
- Like 15 consists of 3×5
Answer:
B
Step-by-step explanation:
The domain is all possible values of x. Here, x is the number of $5 nontaxable items. So x must be an integer, and it can't be negative. It is possible for x to be 0. So x is all whole numbers.
