3:5 = 64cm
3x+5x= 64
8x=64
x=8
Therefore,
3x=8×3
=24
5x=8×5
=40
3x+5x=64cm
Hello :
<span>3y = x + 6 ...(1)
y – x = 3...(2)
by (2) : y = x+3...(*)
subsct in (1) :
3(x+3) = x+6
3x-x= -9+6
2x= -3
x=-3/2
subsct in (*) : y =-3/2 +3 =3/2</span>
Answer:
212.5
Step-by-step explanation:
For triangles, A = (bh)/2
You can do 15+25 to find the base, which is 40. From here do 17*40/2. You get 340. However, you need to remove the right triangle on the left side.
Again do 17*15/2, which you get 127.5.
From here subtract 127.5 from 340 and get 212.5
