I believe it is 4. I am not 100% sure
80 cents Because $1.89 minus $1.09 equals 80 cents
Answer:
no solutions
Step-by-step explanation:
4x + 2y = –14
6x + 3y = –22
Divide the first equation by 2 and the second equation by 3
4x/2 + 2y/2 = –14/2 2x +y = -7
6x/3 + 3y/3 = –22/3 2x + y = -22/3
The left hand sides are the same but the right hand sides are different.
Multiply the second equation by -1
2x+y = -7
-2x -y = 22/3
-------------------
0 = -7+22/3
0 = 1/3
This is never true, so there are no solutions
To solve the problem above on the proportion accident happen more than 1 mile from either of the road please check on the solution below:
area between 1 and 4 = (4 − 1) × 1/5 = 3/5 = 0.<span>6

Hope it helps!
17 ½ % of 240
First option
Change the fraction ½
to a decimal. It would be 0.5 ( 1 divided by 2)
½=0.5
You will add the whole number 17 to the result.
17 + 05 = 17.5
Now you will divide by 100 (percent)
17.5 /100 To divide a
decimal by 100, move the decimal point two
places to the left.
17.5 /100 = 0.175 times 240
0.175 x 240 = 42
Second option
Change the percent to an improper fraction
17 ½= 35/2 (you have to multiply (2 x 17) plus 1 equals 35
over 2 ( keep the denominator). It will be 35/2. Put the other number (240) over 100 and
multiply.
35/2 x 240/100 = 42
There is another way . You can simplify
Cancel all the zeros that you have and start to reduce.
