Step-by-step explanation:
x-c/d>y
d(x)-d(c/d)>d(y)
dx-cd-d^2>dy
dx>dy+cd+d^2
dx>d(y+c+d)
dx/d>d(y+c+d)/d
x>d(y+c+d)/d
Answer:
why such complicated questions.....?
Step-by-step explanation:
I rounded it to 150.
You could round 15.217 down to 15 and 9.54 up to 10 and then multiply 15 x 10 = 150. But you could also multiply 15.217 x 9.54 to get 145.17018 and round that up to 150 because any number that ends with 5 or higher rounds up.
Answer:
A = 47° and B = 43°
Step-by-step explanation:
Express angle A in terms of angle B, that is
A = B + 4
Complementary angles sum to 90°, hence
A + B = 90, that is
B + 4 + B = 90
2B + 4 = 90 ( subtract 4 from both sides )
2B = 86 ( divide both sides by 2 )
B = 43
Hence
∠B = 43° and ∠A = B + 4 = 43 + 4 = 47°
