Let's work this problem out!
First: 5(x) - 26 - x + 50 = ?
Second: 4(x) - 76 = ?
Third: 4 = ?
↑
(Solve Step 3)
Fourth: x - 19 = 0
↑
(Add the number 19 to each of your sides for Step 4)
Finally we get to your answer
19 + 0 = 19 ; 19 - 19 = 0
So, therefore the value of "x" is 19
3.05 x 10³ is already written in scientific notation.
The same number written in standard form is 3,050 .

Alright, so [-2.99] is -2.99, and [2.99] is 2.99, so -2.99+2.99=0
The friction force exerted on the 2400kg car is 9408 Newtons
<h3>
What force will be exerted on the 2400kg car?</h3>
First, we know that the friction force and mass are represented by a proportional relation, this means that we can write:
F = k*M
Where F is the force, M is the mass and k is the constant of proportionality.
We know that for a 1600kg car, a force of 6272N is exerted, replacing that we get:
6272N = k*1600kg
Solving for k we get:
k = (6272N)/(1600 kg) = 3.92 N/kg
Then the proportional relationship is:
F = (3.92 N/kg)*M
So if M = 2400kg, we have:
F = (3.92 N/kg)*2400kg = 9408 N
So the friction force exerted on the 2400kg car is 9408 Newtons
