Answer:
Her original speed is 54 mi/h
Step-by-step explanation:
Here, we want to calculate the original speed
Let this be x mi/h
Mathematically;
distance = speed * time
So she drove at a speed of x mi/h for 2 hours, then (x-10) mi/h for the remaining 1 hour for a total 152 mi journey
Mathematically, we can add up the journey parts as
x(2) + (x-10)1 = 152
2x + x - 10 = 152
3x = 152 + 10
3x = 162
x = 162/3
x = 54 mi/h

Answer:
<h2>x=3</h2>
Step-by-step explanation:
Let's solve your equation step-by-step.
8.88=−2.22(x−7)
Step 1: Simplify both sides of the equation.
8.88=−2.22(x−7)
8.88=(−2.22)(x)+(−2.22)(−7) (Distribute)
8.88=−2.22x+15.54
Step 2: Flip the equation.
−2.22x+15.54=8.88
Step 3: Subtract 15.54 from both sides.
−2.22x+15.54−15.54=8.88−15.54
−2.22x=−6.66
Step 4: Divide both sides by -2.22.
−2.22x
/−2.22
=
−6.66
/−2.22

The coefficients would be 6 and 2.
Coefficient of k would be 6 and for n it would be 2.
