Answer:

\large\boxed{\bf\:9}

Step-by-step explanation:

We have the value of 'n' which is equal to 5.

Now, we need to solve the expression ⟶ n² - 16. To do this, we need to substitute the value of 'n' in this expression.

So,

n^{2} - 16\\= (5)^{2} - 16\\= (5*5) - 16\\= 25 - 16\\= \boxed{9}

___________

Hope this helps!

Rico can walk 3 miles in the same amount of time that Donna can walk 2 miles. Rico walks at a rate 2 miles per hour faster than
tatyana61 [14]

Answer:

13

Step-by-step explanation:

Donna's Rate is R

Rico's Rate is R+2

\frac{R}{R+2}=\frac{2}{3}

Cross-Multiply

2(R+2)=32

2R+4=3R

4=R

Donna's Rate is R=4

Rico's Rate is R+2=6

\frac{6(130)}{60} = \frac{130}{10}=13

5+k-5k=-4k+6 solve for k
marissa [1.9K]

Hey there

the answer is

5+k−5k=−4k+6

5+k+−5k=−4k+6

(k+−5k)+(5)=−4k+6

−4k+5=−4k+6

−4k+5+4k=−4k+6+4k

5=6

5−5=6−5

0=1

thank you

best regards
