32 = .49x
32/.49 = 65.306122449
Answer:
DB = 82
Step-by-step explanation:
3x + 8 + 4x + 10 = 8x
7x + 18 = 8x
18 = 8x - 7x
18 = x
----------------------------------------
DB: 4x + 10
4 (18) + 10 = 82
24.5 would be your answer :)
Answer: 0.53
Step-by-step explanation:
From variation ,
y ∞ x ------------------------------------------------1
y = kx , where k is called the constants of proportionality and must be calculated first before proceeding.
substitute for the values in equation 2 ,below
y = kx -----------------------------------------------2
16 = k2.1
k = 16/2.1
Now to find the value of x, make x the subject of the formula in equation 2
x = y/k
= 4/ 16/2.1
= 4 ÷ 16/2.1
= 4 x 2.1/16
= 2.1/4
= 0.525
≅ 0.53
