Answer:
x=4
Step-by-step explanation:
You put 9x+6y=78 over 3x-6y=-30. Then, you are going to add the two equations. So, you are going to do 9x+3x, 6y-6y (since the second 6 is negative, it ends up subtracting), and 78-30. You will end up canceling the 6y's, and end up with 12x=48. Then, you will divide 48 by 12, and get x=4. Hope this helped:)
Answer:
c=27/40 = 0.675
Step-by-step explanation:
the statement give us the expression:
1/8 +c= 4/5
we subtract the term "1/8" both sides:
we have:
1/8 -1/8+c= 4/5-1/8
c=4/5-1/8
c=(4*8)-(5*1)/(5*8)
c=(32-5)/(40)
c =27/40 = 0.675
Answer:
He should order 15 long boards
Question:
Escape park owner want 30% of each order to include long boards he wants to know how many long boards to order out of a total of 50 skateboards
Step-by-step explanation:
Let x and y represent the number of long board and the total number of skateboard to order.
Given that 30% of each order to include long boards;
x = 30% of y
x = 0.3y .....1
But, the total number of skateboard is given as 50
y = 50
From equation 1
x = 0.3y = 0.3(50)
x = 15
He should order 15 long boards
