-3/5 × 3/7 + 4/5 – 3/7 × 1/10
(-3) × 3 ÷ 5(7) + 4/5 – 3 × 1 ÷ 7(10)
-9/35 + 4/5 – 3/70
-9/35 – 3/70 + 4/5
-9 × 2/35 × 2 – 3/70 + 4/5
-18 – 3/70 + 4/5
-21/70 + 4/5
-3/10 + 4/5
(-3)(5) + (10)(4) ÷ (10)(5)
-15 + 40/50
25/50 = 1/2
Thus, The answer is 1/2

Answer:
c
Step-by-step explanation:
511 divided by 7 is the unit rate. So a is how you get it but d is the answer
EDBC is a trapezoid
We know AC=8 and since the sides of an isosceles right triangle are in ratio
we conclude
We have a square so AD=ED=EF=4.
DB is the height of the trapezoid,
So the area of the trapezoid is
AFECB is the sum of two isosceles right triangles AFE + ABC so has area
That's a ratio of 8:24:8 or 1:3
That must mean that ADE and AFE each have area 8 as well.
Answer: 1/3
