Answer:
24 blue cars
Step-by-step explanation:
Set up a proportion to solve this...
40/5 = x/3 (forty red cars is to five red cars as 'x' number of blue cars is to 3 blue cars)
Now solve by cross multiplying...
120 = 5x
24 = x
Sixty four. i hope this helps
With these given values:
<span> f(0)=4 and f′(x)≤4
</span>
The solution is as follows:
<span>f(0) = 4
f ' (x) ≤ 4 for all x
The Mean Value Theorem says there is a c between 0 and 4 such that f ' (c) = [f(4) - f(0)] / (4 - 0)
But since f ' (x) ≤ 4 for all x, then [f(4) - f(0)] / (4 - 0) ≤ 4
Since f(0) = 4, then [f(4) - 4] / (4 - 0) ≤ 4
Multiplying both sides by 4 you get f(4) - 4 ≤ 16
Adding 4 to both sides you get f(4) ≤ 20
So f(4) ≤ 20

By examining the solution, it could guide you on answering the problem on your own. Hope that helps
Hello!
You can solve this algebraically
6(z + 6) = 3(2z + 12)
Distribute the 6
6z + 36 = 3(2z + 12)
Distribute the 3
6z + 36 = 6z + 36
Since both sides are the same there are in infinite amount of solutions
The answer is an infinite amount of solutions
Hope this helps!
<span>If QRST is a rectangle with QT = 50 and RS = 4x + 8, find x.
.
QT = RS (opposite sides of a rectangle are equal)
50 = 4x + 8
42 = 4x
10.5 = x</span>
