1. You can subtract everything with the same “value” so that means you can subtract 3x from 6x, 5y - 5y and 39 - 27. This will give you: 3x + 0 = 12. Because 0 isn’t anything you get 3x = 12. Dividing everything by 3 you get x = 4
Answer: 13/6
Step-by-step explanation:
Based upon the previous sequence.
1.there is a constant decrease of two in the numerator
2. There is a constant increase of one in the denominator
to find the fourth number in the sequence I used One of the numbers from the previous to determine the answer.
17/4 — —> then I followed the pattern and determine what fraction 3 was . . before it was converted into a whole number.
which would be 15/5 —> Now considering equations that are written like this also mean division, because in this case division is possible the answer would be 3, which would make the whole number 3 instead of 15/3. considering it was an improper fraction.
____________________________________________________________
Now If 15/5 wasn’t converted into 3, The answer to the sequence would be 13/6. If you follow the pattern like I said before there is a certain amount of increase and decrease so 13/6 will be your answer. The only reason is not a whole number because 13 can’t be divided by six to get a whole number.
Answer:
The solution to the system of equations will be:
Step-by-step explanation:
Given the system of equations
Multiply 2x-9y=-36 by 7
so the system of equations becomes
Adding both equations
solve -45y = -270 for y
divide both sides by -45
Simplify
For 14x-63y = -270 plug in y = 6
Add 378 to both sides
Simplify
Divide both sides by 14
Simplify
Therefore, the solution to the system of equations will be:
Answer:
Step-by-step explanation:
fun one - thanx 4 posting!!!
let the interaction of BK and NO be P
and NO be x
triangle NBO n ABC are similar by AAA as NO // AC
so BP/BK=NO/AC=x/30
BP=10*x/30=x/3
PK=height of triangle NMO
cuz' NM=MO n m∠NMO=90°
height of triangle NMO=NO/2=x/2
PK=x/2
area of triangle NBO + area ot trapezoid NOCA = area of triangle ABC
BP*NO/2 + (NO+AC)*PK/2 = BK*AC/2
(x/3)*x/2+(x+30)*x/2 = 10*30/2
simplifying x^2/6+x^2/4+30x/4=150
5x^2+90x-1800=0
solving x=12 or x=-30
as length cannot be negative
NO=12
Answer:
Tip: $3.70
Total: $28.49
Step-by-step explanation:
1. Finding the tip:
a. tip = total cost * rate of tip
or you could do it as a proportion, which would be
b. tip percent/100 = tip/total cost
use cross products to get the tip, then add it to the total price.
I hope this helped.
