Combine like terms:

$4n+5n=-9\\ 9n=-9$

Isolate the variable on one side of the equation:

$9n=-9\\ n=-1$

The answer is $n=-1$ .

add 4n and 5n, which is 9. 9n=-9, and if u divide both sides by nine, n=-1

Answer: 5 years

Step-by-step explanation:

A= P(1-r)^t

A= Depreciation value

P = Initial amount

r= rate = 7/100= 0.07

t= time

t= (Ln(A/P))/Ln(1-r)

= (Ln(25949.18/37300))/Ln(1-0.07)

t= 4.999 approximately 5 years

Solve for t: d = rt<br> What's the answer please? Need help

SVETLANKA909090 [29]

If you're solving for d your answer is d = -t,rt
If you're evaluating the problem your answer is t = d/r
If you're solving in terms of arbitrary letter d your answer is r=d/t
I hope this helps!

If you assume the samples are representative how many whole wheat bagels might you infer are sold at each store

Alexxandr [17]

Maurine owns three bagel shops. Each shop sells 500 bagels per day. Maureen asks her store managers to use a random sample to see how many whole wheat bagels are sold at each store each day. Shop A has total of 50 bagels in sample and 10 are whole wheat bagels. Store B has a total of 100 bagels in sample and 23 are whole wheat bagels. Shop C has 25 total bagels in sample and 7 are whole wheat bagels.

We find fraction of whole wheat bagels to the sample for each shop using given information

Shop A = $\frac{10}{50} = 0.20$
