Answer:
y=-10
Step-by-step explanation:
In this problem you're trying to figure out what y equals.
First you subtract 11 from both sides.
30=-3y
Then, you divide each side by -3 to find y.
-10=y
y=-10
It is not an equilateral triangle. To prove this, you must solve for x. I found x by setting 2x+5.2 = 3x+1.2 to get x=4. Then I plugged 4 into equation to see if they were equal. 2(4)+5.2= 13.2 and 3(4)+1.3=13.2 but 2(4)+6.2=14.2. This allows us to conclude that the triangle is not equilateral because all of the sides are NOT congruent. Hope that helped:))

Answer:
Area of polygon = 16.11 square cm
Step-by-step explanation:
From the figure we can divide the polygon into two quadrilateral,
1) a square with side 3.6 cm
2) a rectangle with dimensions 2.1 x 1.5
<u>To find the area of square</u>
Area = side x side = 3.6 x 3.6
= 12 .96 square cm
<u>To find the area of rectangle</u>
Area = Length x Breadth
= 2.1 x 1.5 = 3.15 square cm
<u>Area of polygon</u>
Area = 12.96 + 3.15 = 16.11 square cm
Answer:
A proportional relationship is written as:
y = k*x
where k is the constant of proportionality.
A general word problem that represents one of these relationships can be:
If each burger costs $1.50, what would be the cost of buying x burgers?
The cost of x burgers will be x times $1.50, so if we define y as the total price, we will have the relation:
y = $1.50*x
Which is a proportional relationship where the constant of proportionality is $1,50
