Solve 20x + 12 ≥ 14x + 30
Rashid [163]

Subtract 14x from both sides to get

20x-14x+12 \geq 30

Subtract 12 from both sides to get

20x-14x \geq 30-12

Now we have moved all terms involving x on one side, and all constant terms on the other. We can simplift both sides, i.e. sum like terms, to get

6x \geq 18

Now we have to divide both sides by 6. When dealing with inequality you have to be careful about dividing both sides by the same constant: if the constant is negative, the inequality side switches (i.e. \geq \leftrightarrow \leq). But this is not the case since 6 is positive, so we mantain the inequality sign:

on the other. We can simplift both sides, i.e. sum like terms, to get

\cfrac{6x}{6} \geq \cfrac{18}{6}

Evaluate left and right hand side:

x \geq 3

A 2956 kg car starts from rest at the top of a driveway of length 6 m that is sloped at 35◦ with the horizontal. An average fric
zepelin [54]

Answer:

7.41 m/s

Step-by-step explanation:

Force of a car inclined at an angle

F=mg Sin Θ where; m = 2956 kg , g = 9.8m/s² , Θ = 35⁰

F = 2956 x 9.8 x Sin 35 = 16615.82 N

Net force due to friction = 16615.82 - 3080 = 13535.82 N

To calculate acceleration; F= Ma

13535.82 = 2956 x a

a = 4.58 m/s²

From equation of motion

V^{2} = V_{o} ^{2}  + 2aS

V² =  0 + (2 x 4.58 x 6)

V = \sqrt{54.95}

V = 7.41 m/s
