Step-by-step explanation:
First get x on its own:
Subtract 3 from each side
y - 3 = 2x
Divide through by 2
y/2 - 3/2 = x
or x = y/2 - 3/2
Now simply switch labels: x↔y
y = x/2 - 3/2
SA= 49.5 (m but it says no units)
Explanation: find the area of one of the triangles, A=(b*h)/2, and then one of the rectangles, A=l*w. Multiply the triangles area by two, there are two triangles. Multiply the rectangles areas by three, there are three rectangles. I’ve included calculations in the picture below.
Answer:
16,30.34
Step-by-step explanation:
Answer:
k = 3
Step-by-step explanation:
We have the distance formula: 
. We can plug in 
= d, x2 = 6, x1=2, y2 = 7, y1 = k.
Then, we can solve the question using some algebra to find that k = 3.
Edit: Here is a step by step:
