if you're looking for x, minus the one so it's 13x=-1 and divide. hope it was helpful
slated surface
17 × 20 = 340
2 triangle sides
2 × 8 × 15 ÷ 2 = 120
backside
8 × 20 = 160
bottom
15 × 20 = 300
sum all of it
340 + 120 + 160 + 300 = 920
can I get brainliest
When I divided 4/7, I got .5714285714 then I divided 13/20, and I got .65 so I would say 4/7 I believe.
When I divided 1/4, I got .25 then I divided 1/6, and I got .1666666667 so I would say 1/4 I believe.
When I divided 5/6, I got .8333333333 then I divided 2/3, and I got .6666666667 so I would say 5/6 I believe.
I definitely hope this helps you, I tried my best! XO
