Let D be dogs and C be cats

<em>dogs, d, is initially five less than twice the number of cats, c</em>

D + 5 = 2C

<em>If she decides to add three more of each, the ratio  of cats to dogs will be</em>

D + 8 = 2C + 3

<em>Could Bea's Pet Shop initially have 15 cats and 20 dogs?</em>

Simply plug in the numbers

20 + 5 = 2(15)

This is clearly not true: 25 does not equal 30

Rewrite the given expression in the form 3^u where u is a constant or an algebraic expression.
lawyer [7]
Simplifying the given expressions we proceed as follows:
(5sqrt3)^x
=5^x*(3^1/2)^x
=5^x*3^x/2
=5^x3^u
where u=x/2


(1/2)^(x-3)
=1/2^(x-3)
=2^-(3-x)
=2^u
where u=-(3-x)

9/3sqrt(3)
=3/(3)^(1/2)
=3(3)^(-1/2)

16/(3sqrt (2^x))
=1/3*(2^4*2^(-x/2))
=1/3*2^(4-x/2)
=1/3*2^u
where:
u=4-x/2

Kryger [21]

Answer:

2.35 miles

Step-by-step explanation:

Please find the attachment for visual understanding.

We are told that the library is 1.75 miles directly north from the school and the park is 0.6 miles directly south of the school.

To find distance between library and park we will add distance of library from school to the distance of park from school.

(1.75+0.6)\text{ miles}=2.35\text{ miles}  

Therefore, library is 2.35 miles away from park.

SSSSS [86.1K]
The unknown side is 9. Because 9 x 5= 45, 45 being the perimeter, that is 5 times the unknown side. And 45 is the sum of 9, 16, and 20.

Gavin wrote the equation p=3(s+100)/4 to represent p, the profit he makes from s sales in his lawn-mowing business. Which equati
Sindrei [870]
Given the equation p = 3(s + 100)/4 

Where,
p = profit made
s = sales 

Solving for s from the given equation

p = 3(s + 100)/4

Multiply both sides by 4
4p = 3(s + 100)
4p = 3s + 300

Subtract 300 from both sides of the equation
4p – 300 = 3s
Same as, 3s = 4p – 300

s = (4p – 300)/3 
OR, s = 4p/3 – 100 
If any of these two is in the options, it’s the right answer.
