Answer:
D= 49/8
Step-by-step explanation:
Cross-multiply.
(2d-5)/2 = (5d+2)/9
(2d−5)*(9)=(5d+2)*(2)
18d−45=10d+4
Subtract 10d from both sides.
18d−45−10d=10d+4−10d
8d−45=4
Add 45 to both sides.
8d−45+45=4+45
8d=49
Divide both sides by 8.
d= 49/8
So the answer is 49/8
I hope it's right!
Answer:
-7
Step-by-step explanation:
2.5x - x + 10 = x - x - 0.5
1.5x + 10 - 10 = -0.5 - 10
1.5x/1.5 = -10.5/1.5
x = -7
The correct answer is C 41 square units
