100 notes were altogether
<em><u>Solution:</u></em>
Given that ratio of the number of $2 notes to the number of $5 notes was 4 : 1
number of $2 notes : number of $5 notes = 4 : 1
Let 4x be the number of $ 2 notes
Let 1x be the number of $ 5 notes
Given that total value of notes is $ 260
Therefore,
$ 2 (number of $ 2 notes ) + $ 5(number of $ 5 notes ) = $ 260
$ 2(4x) + $ 5(1x) = $ 260
8x + 5x = 260
13x = 260
x = 20
<em><u>Thus number of notes altogether is given as:</u></em>
4x + 1x = 4(20) + 1(20) = 80 + 20 = 100
Thus 100 notes were altogether
-18x
you first times the numbers, which becomes -18
Next you add the exponent from the veriables (x) (if you're diving you're subtractiong example: x^a/x^b = x^a-b)
Sooo when you add them you get 8-7=1 which means.. x^1 (but you don't need to put the 1)
-18x
It should be 34.3 because I think you have to add up all the numbers
Answer:
4³
Step-by-step explanation:
2 / 2 = 1
4 raised to the power of one is 4
4 raised to the power of 3 is 4³
Lets label hot dogs as 'h' and soft drinks as 'd'
6h + 4d = 13
3h + 4d = 8.50
We can solve by process of elimination.
Subtract the first equation from the second one.
We get:
3h = 4.5
Solve for h
<span>h = 1.5 </span>
<span>That means that the hot dog costs $1.50 which is answer choice </span>D.
<span>Hope that helps :)</span>
