Just divide 450 by 50 and your answer is 9 in
Answer:it’s the one with 10 units on the side
Step-by-step explanation:
10 divided by 1/2 is 5
Equation 1) 2x - 3y = -1
Equation 2) y = x -1
Rearrange equation 2 so that x and y are on the same side. To do so, you subtract x from both sides.
2) -x + y = -1
1) 2x - 3y = -1
Multiply ALL of equation 2 by 2.
2) 2(-x + y = -1)
Simplify.
2) -2x + 2y = -1
1) 2x - 3y = -1
Add equations together.
-y = 0
So, y = 0
Plug in 0 for y in the first equation.
2x - 3y = -1
2x - 3(0) = -1
Simplify.
2x - 0 = -1
2x = -1
Divide both sides by 2.
x = -1/2
(-1/2 , 0)

Answer:
-485
Step-by-step explanation:
Formula
<em><u>Givens</u></em>
an = a28
n = 28
a1 = - 242
<em><u>Solution</u></em>
d = a3 - a2
d = -260 - - 251
d = -260 + 251
d = - 9
an = a1 + (n-1)d
an = -242 + (n - 1)(-9)
a28 = - 242 + 27*(-9)
a28 = - 242 - 243
a28 = - 485
For number 5, the area is 195
because Area = Base x Height
so 13 x 15 = 195
I don’t know number 6 yet
