Answer:
(a)
(b)
the price of 50 cloud markers is $37.2
Step-by-step explanation:
(a)
Let's assume
price is P
number of markers is N
We are given
The price of a box of 15 cloud markers is $12.70
so,
The price of a box of 42 cloud markers is $31.60
so,
Firstly, we will find slope
now, we can plug values
now, we can use point slope form of line
we can plug value
now, we can solve for P
add both sides by 12.70
(b)
now, we can plug N=50
So,
the price of 50 cloud markers is $37.2
Area of the square = 6 * 6 = 36
area of 1 triangle = 1/2 x 6 * 4 = 12
area of 4 triangles = 4 * 12 = 48
total area = 36 +48 = 84 sq. cm
5x - 7y =58
y =-x +2
Using the substitution method, replace y in the first equation with the second equation:
5x - 7(-x+2) = 58
Simplify by using the distribution property:
5x - (-7x) - 14 = 58
Simplify by combining like terms:
12x -14 = 58
Add 14 from each side of the equation:
12x = 72
Divide both sides by 12:
X = 72/12
x = 6
Now you have x, replace x in the second equation and solve for y:
y = -x +2
y = -6 +2
y = -4
X = 6, y = -4
Answer
i believe the answer would be 3^9
hope this helps and have a wonderful day :)
