Answer:
cost to make paper signs = $1
cost to make laminated signs = $2
Step-by-step explanation:
Let
x = cost to make paper signs
y = cost to make laminated signs
8x + 2y = 12 (1)
10x + 10y = 30 (2)
Multiply (1) by 5
40x + 10y = 60 (3)
10x + 10y = 30 (2)
Subtract (2) from (3) to solve for x
40x - 10x = 60 - 30
30x = 30
x = 30/30
x = $1
Substitute x = 1 into (1)
8x + 2y = 12
8(1) + 2y = 12
8 + 2y = 12
2y = 12 - 8
2y = 4
y = 4/2
y = $2
cost to make paper signs = $1
cost to make laminated signs = $2
Answer:
m - i = r
Step-by-step explanation:
In this question, you are solving for "r".
Solve:
M= i + r
We have to get "r" by itself, so subtract "i" from both sides.
m - i = r
Since we found what "r" is, we can't solve any further.
m - i = r would be your answer.
Area of a triangle is given by half the product of two of the sides and the sine of the included angle.
Thus, the area of the triangle is 0.5 x 27.6 x 30 x sin 23^o = 161.76 cm^2
Answer:
50
