STEP 1) 7x+10x+12x= 232 STEP 2) 29x = 232 STEP 3) divide 232 by 29 STEP 4) x=8 STEP 5) 7 times 8 = 56, 10 times 8 = 80, 12 times 8 = 96. the highest score was a 96
Solving the second equation for y..
2x-y=7 divide both sides by -1
y-2x=-7 add 2x to both sides
y=2x-7
When a solution exists, y=y, so we can say:
2x-7=2x+3 subtract 2x from both sides
-7=3
-1 != 3
Since the above is never true, there are no solutions to this system of equations.
Intuitively, this is because both lines have the same slope, they are parallel, and have an different y-intercept, thus they will never cross each other...
Answer:
Step-by-step explanation:
Given
Required
Number of books in 1 week
Represent the number of books in 1 week with x.
So, we have:
Cross Multiply
Convert fraction to improper fraction
Multiply through by 
<em>Hence: 12/7 books were read in a week</em>
Answer:
Yesss, that's correct!
Step-by-step explanation:
Good luck!!!!
Subtract 5 from both sides
so now it should be like this
-3p=-8p+5
Now add 8p to both sides
now it should look like this
5p=5
now divide
5/5= 1
sp p=1
