15 squares are needed to make the eighth figure in the pattern
In this problem why is the easiest to substitute.
Just set the equations equal to each other because they both equal y
-x + 4 = 2x - 8
(You want to get all the x's to one side so add x to each side)
4 = 3x - 8
(next add 8 to both sides)
12 = 3x
(lastly divide 3 from both sides)
4 = x
You have got your x so now it is time to find that y just replace x to either of the two equations
y = 2(4) -8 or y = -(4) + 4
y = 8 - 8 y = 0
y = 0
Final Answer: y=0, x=4
Answer:
1 inch = 8 miles
112÷14=8, so one inch is 8 miles.
Answer:
4.4x+9.4
Step-by-step explanation:
x(3.8)-x(2.6)+3+3.2(x)+3.2(2)
3.8x-2.6x+3+3.2x+6.4
Combine all of x's with the blanks
4.4x+9.4
Answer:
Hope it helps
Step-by-step explanation:
I predict that most of the students that didn't sign up yet, are going to play tug of war. The 45 student that sign up for tug of war are at 22.5%, then for the relay race( 7.5 %) and hula hoop contest is 10 %.
