You divide 44 by 9 and get 4.89 so u can round up either to the 8 or the 4 is you could get either 4.9 or 5
The y intercept in the equation is -2. What is your question?
9514 1404 393
Answer:
21
Step-by-step explanation:
The number who bought expensive tickets is 3/5 of the number who bought cheap tickets.
(3/5)(35) = 21
21 people bought the more expensive ticket.
Answer:
C. 43.6
Step-by-step explanation:
you need to take the area of each shape
lets do the skinny triangles first on the top and bottom of this shape.
so to find the formula of triangle we need to do 0.5 * 1.26 * 5.3
because the formula of a triangle is half the base times height.
so we get 0.5 * 1.26 * 5.3 = 3.339
multiply it by two and we get 6.678
now lets find the area of the huge rectangle on the back/behind of the shape
3.3*5.3 = 17.49
now lets find the area of the two smaller rectangles
3.3 * 3.6 = 11.88
2.3 * 3.3 = 7.59
now lets add
6.678 + 17.49 + 11.88 + 7.59 = 43.638
round it to 43.6
For systems of equations try using graphing, substitution, and elimination. For example
{2x+7y=3}
{x=-4y}
You should first look at if you have a variable that can be substituted (using substitution) and in this case we do! you plug in the x into 2x meaning 2(-4y)+7y=3
1) distribute -8y+7y=3
2) combine like terms in this case -8y+7y= -1y
3) solve -1y=3
y=-3
so currently our solution is (0,-3)
now we solve for x.
we plug our solved variable (y) into 7y
7(-3) and our equation looks like this
2x+7(-3)=3
1) distribute 7(-3)=-21
2) rewrite then solve 2x+(-21)=3
3) isolate variable -21+21 & 3+21
4) 2x=24
5) solve 2/24 = 12
Meaning our solution is (12,-3)
This is how to solve by substitution.
