Answer:
Slove For X
x= -1
Solve for Y
Y= 10/3
Step-by-step explanation:
SO I did Elimination method
To isolate X and to solve for it
x+3y=9
3x−3y=−13
Add these equations to eliminate y:
4x=−4
Solve for X
x=-1
Now plug x back in to solve for y
Answer:
Insert the numbers into the equation y=3x-5.
the rule states that in every equation the first number is x.so it will be -6=3(4)-5
-6=12-5
-6=7.
If u want, you can leave your answer like that
First, you need to divide 12.5/2.5= 5. After that, you need to multiply 17.50x5=87.50. So your answer is $87.50.
To get the answer you would:
Multiply 525 by 1.2 525*1.2=
which equals 630
then you would add 525 to 630 525+630=
So the answer would be:
1155
Hope this helps
Answer:
13 pears in the 21st bag
Step-by-step explanation:
mean = total number of pears/total number of bags
8 = x/21
x = 168
number of pears in 20 bags = (6 x 2) + (7 x 6) + (8 x 9) + (9 x 1) + (10 x 2)
= 155
number of pears in the 21st bag = 168 - 155
= 13
