Answer: f(3)=-7

Step-by-step explanation:

To evaluate f(3), we want to plug in x=3 into f(x)=-4x+5.

f(3)=-4(3)+5 [multiply]

f(3)=-12+5 [add]

f(3)=-7

Now, we know that f(3)=-7.

Answer:

x = 1.5

Step-by-step explanation:

-1.2 (3 - x) = -1.8

Apply distributive property

-3.6 + 1.2x = -1.8

Get 1.2x alone so add -3.6 to each side

1.2x = 1.8

Get x alone so divide 1.2 on each side

x = 1.5

Hope this helps!

Alicia walks 4 miles in 1 hour and can speed walk 5 miles in 1 hour. What percent of Alicia's average speed walking rate is her

RSB [31]

Answer:

The % Alicia speed walking is 125 % of average walking

Step-by-step explanation:

Given as :

Distance cover by Alicia while walking = 4 miles

Time taken = 1 hour

So, Speed of Alicia while walking = $\frac{Distance}{Time}$

Or, S 1 = $\frac{4 miles}{1 hour}$

I.e S 1 = 4 mph

And

Distance cover by Alicia while speed walk = 5 miles

Time Taken = 1 hour

So, Speed of Alicia while speed walking = $\frac{Distance}{Time}$

Or, S 2 = $\frac{5 miles}{1 hour}$

I.e S 2 = 5 mph

Or, % Rate = $\frac{5}{4}$ ×100 = 125

Hence The % Alicia speed walking is 125 % of average walking Answer
