Answer:
$160
Step-by-step explanation:
This student is incorrect because there is no number that you can multiply by 2 to get 5. Therefore, the proper point would be (1, 5) as the equation is setup as x+2y=5, so x must equal 1, and y must equal 2. Now to check if its correct:
1+2(2)=5
2x2=4
1+4=5
It is correct, so the answer is (1, 5)
Answer:
The measure of angle B would be 100°
Step-by-step explanation:
Supplementary means two angles add up to 180 degrees. Let's say A+B=180. Since we know what A is, we can substitute that in, B+80=180. Now solve. B=100
Answer:
435 ft
Step-by-step explanation:
area of triangle:
A = (b x h) : 2
A = (15 x 4) : 2
A = 60 : 2
A = 30 ft
area of rectangle:
A = b x h
A = 25 x 15
A = 375 ft
area of the yard = area of the triangle + area of the triangle + area of the rectangle (Here, both triangles have the same area.)
area of the yard: 30 + 30 + 375 = 435 ft.
So, the area of the yard is 435 ft.
