Answer is c. $62.99
Step by step
89.99 x 70% = x
89.99 x .70 = 62.99
Hint: If the dress was 30% off, it’s cost is 70%
You can also do this in two steps
89.99 x 30% = discount of $27.
Then
89.99 - $27 = $62.99
Answer:
x=2 y=1
Step-by-step explanation:
Solve the equations by substituting y=6x-11 into -2x-3y=-7.
-2x-3(6x-11)=-7
-2x-18x+33=-7
-20x+33=-7
-20x=-7-33
-20x=-40
x=2
To find y, substitute this value into the equation and solve for y.
y=6(2)-11
y=12-11
y=1
You must be aware that two adjacent sides are simply two lines that meet and form an angle in between them.
You are given that the sum of interior angles in a polygon (S) = 180°(n - 2) where n is the number of sides.
Therefore;
180°(n - 2) = 1260° (We are to find the value of n)
n - 2 = 1260°/180° = 7
n = 7 + 2 = 9
The polygon have 9 sides.
Hi it will either be option 3
