All that has to be done here is to divide the number of inches by the measurement of a finger. So, divide 25 by 4 1/2 and you get approximately 5.55 fingers. The 5 repeats endlessly so bar notation can be used. If the answer is needed as a fraction, change 4 1/2 to an improper fraction to get 9/2. In this case, you're dividing 25 by 9/2, which is the same thing as multiplying 25 by 2/9, the reciprocal of 9/2. This gives you a total of 50/9 fingers, or 5 5/9 fingers as a mixed fraction.
Equation 1) -2x-y=-9
Equation 2) 5x-2y=18
Multiply all of equation 1 by 2, so that both equations have (2y) in them.
1) 2(-2x-y=-9)
Simplify.
1) -4x-2y=-18
2) 5x-2y=18
Subtract equations with each other.
-9x=-36
Divide both sides by -9.
x=4
Plug in 4 for (x) into equation 1.
-2x-y=-9
-2(4)-y=-9
Simplify.
-8-y=-9
Add 8 to both sides.
-y=-1
Divide both sides by -1.
y=1
(4, 1)
~Hope I helped!~
Answer: Yes! -5 is greater than -9, because with negatives the smaller numbers are the greatest because they are below 0. Have a good day and Good Luck!
Step-by-step explanation:
Answer:
x=18
Step-by-step explanation:
<u>Key skills needed: Arithmetic Sequences, Addition</u>
1) We have a sequence of 8,13,x
2) To find the number being added every time, we do 13-8. This is 5.
3) This means x would be 13+5
4) 13+5 is 18 so x is 18.
