Answer: d < 13/2
Step-by-step explanation:
Rearrange:
Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :
8*d-5-(6*d+8)<0
Step by step solution :
Step 1 :
1.1 Divide both sides by 2
d-(13/2) < 0
Solve Basic Inequality :
1.2 Add 13/2 to both sides
d < 13/2

Answer:
x = 13
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ the parallel bases
Here A = 55, h = 5. b₁ = x, b₂ = 9, then
× 5 × (x + 9) = 55
2.5(x + 9) = 55 ( divide both sides by 2.5 )
x + 9 = 22 ( subtract 9 from both sides )
x = 13
