Inequalities are used to represent unequal expressions

The solution to the inequality is: $x > -3$

<h3>How to determine the inequality solution</h3>

The inequality is given as:

60>5(6-2x)

Rewrite the inequality properly as:

$60>5(6-2x)$

Divide both sides of the inequality by 5

$12>6-2x$

Subtract 6 from both sides of the inequality

$6>-2x$

Divide both sides of the inequality by -2

$-3Rewrite the inequality as[tex]x > -3$

Hence, the solution to the inequality is: $x > -3$

Solve for x. −ax + 4b > 9 plz help me

likoan [24]

Answer:

x < $\frac{9-4b}{a}$

Step-by-step explanation:

Given

- ax + 4b > 9 ( isolate the term in x by subtracting 4b from both sides )

- ax > 9 - 4b ( divide both sides by - a )

Remembering to reverse the inequality symbol when dividing by a negative quantity, thus

x < $\frac{9-4b}{a}$

Matt and Anna Killian are frequent flors on Fast-n-Go Airlines, They often fly between two cities that are a distance of 800 mil

inna [77]

Answer:

The speed of the wind is 40mph, the speed of the plane in still air is 360mph

Step-by-step explanation:

distance = speed * time

Both legs of the trip are 800 miles, let 'x' represent the speed of the plane in still air and 'w' represent the speed of the wind, then 'x+w' represents the speed with the wind and 'x-w' represents the speed into the wind

800 = (x-w)2.5

800 = (x+w)2

Rewrite equations:

800=−2.5w+2.5x;800=2w+2x

Steps: Solve 800=−2.5w+2.5x for w:

800=−2.5w+2.5x

800+2.5w=−2.5w+2.5x+2.5w(Add 2.5w to both sides)

2.5w+800=2.5x

2.5w+800+−800=2.5x+−800(Add -800 to both sides)

2.5w=2.5x−800

2.5w/2.5 = 2.5x - 800 / 2.5 (Divide both sides by 2.5)

w=x−320

Step: Substitute x−320 for w in 800=2w+2x:

800=2w+2x

800=2(x−320)+2x

800=4x−640(Simplify both sides of the equation)

800+−4x=4x−640+−4x(Add -4x to both sides)

−4x+800=−640

−4x+800+−800=−640+−800(Add -800 to both sides)

−4x=−1440

-4x/-4 = -1440/-4 (Divide both sides by -4)

x=360

Step: Substitute 360 for x in w=x−320:

w=x−320

w=360−320

w=40(Simplify both sides of the equation)

solving this system we have:

w=40

x=360

Therefore, the speed of the wind is 40mph, the speed of the plain in still air is 360mph
