Answer:

x = 2(z -y)

Step-by-step explanation:

Multiply by the inverse of the coefficient of x.

x = 4y(z -y)/2y

x = 2(z -y) . . . . . . . . y ≠ 0

Brian is riding his bike. He biked a distance of 14 miles at a rate of 14 miles per hour. Rearrange the distance formula, d = rt

Mariana [72]

Answer:

60 minutes

Step-by-step explanation:

The distance formula is:

D = RT

Where

D is distance (in miles)

R is rate (in miles per hour)

T is time (in minutes)

Given,

D = 14 miles

R = 14 miles per hour

We want to find T, so we have:

$D=RT\\T=\frac{D}{R}\\T=\frac{14}{14}\\T=1$

So the time is 1 hour

We want in minutes, and we know 60 minutes is 1 hour, so the time (in minutes) is 60 minutes

Solve for b.<br> ab +c=d

timama [110]

Answer: B = $\frac{-c}{a}$ + $\frac{d}{a}$

Step-by-step explanation:

you need to get B alone so that would be subtracting everything around it

ab = -c + d

then you need to get that a away from it by dividing both sides by A

B = $\frac{-c}{a}$ + $\frac{d}{a}$
