sesenic [268]

Answer:

15 lb

Step-by-step explanation:

let the current weight of the puppy be X, the  initial weight of the puppy is 4lb or \frac{2}{3}X-6\ lb, (6 lb less 2/3 X) .

#We equate the current weight to the initial weight to determine X:

4\ lb=\frac{2}{3}X-6\ lb\\\\10 \ lb=\frac{2}{3}X\\\\X=15

Hence, the current weight of the puppy is 15 lb

One can convert temperature from Kelvin into Fahrenheit using the formula F=95(K−273)+32. What is the temperature in Kelvin corr
DiKsa [7]

Answer:

The temperature in Kelvin corresponding to F degrees Fahrenheit is K=\frac{F-32}{95}+273

Step-by-step explanation:

Given : One can convert temperature from Kelvin into Fahrenheit using the formula F=95(K-273)+32.

To find : What is the temperature in Kelvin corresponding to F degrees Fahrenheit?

Solution :

Temperature from Kelvin into Fahrenheit is given by,

F=95(K-273)+32

Writing Kelvin in terms of Fahrenheit,

Subtract 32 both side,

F-32=95(K-273)

Divide by 95 both side,

\frac{F-32}{95}=K-273

Add 273 both side,

\frac{F-32}{95}+273=K

Therefore, The temperature in Kelvin corresponding to F degrees Fahrenheit is K=\frac{F-32}{95}+273

A party rental company chairs and tables for rent. The total cost to rent 2 chairs and 12 tables is $105. The total cost to read
Luden [163]

Answer:

Step-by-step explanation:

2c+12t=105, and 5c+3t=33, subtracting 4 times the second from the first gives you

2c+12t-20c-12t=105-132

-18c=-27 dividing each side by -18

c=1.5, making 2c+12t=105 become

2(1.5)+12t=105

12t=102

t=8.5

So each chair costs $1.50 and each table costs $8.50

When the polynomial in P(x) is divided by (x + a), the remainder equals P(a)
disa [49]

Answer:

This is a false statement:

Step-by-step explanation:

According to Remainder Theorem dividing the polynomial by some linear factor x + a, where a is just some number. As a result of the long polynomial division, you end up with some polynomial answer q(x) (the "q" standing for "the quotient polynomial") and some polynomial remainder r(x).

P(x)= (x+/-a) q(x)+r(x)

P(x)=(x+a) q(x)+r(x). Note that for x=-a

P(-a)=(-a+a) q(-a)+r(-a)= 0* q(-a)+ r(-a)

P(-a)=r(-a)

It means that P(-a) is the remainder not P(a)

Thus the given statement is false....
