Rick's cat weighs 7 pounds. His neighbor says her puppy weighs 103 ounces.
Does Rick's cat weigh more than the puppy?
1 pound = 16 ounces )
How much does Rick's cat weigh in ounces?

Answers

Answer:

1. Yes

2. 112 ounces

Step-by-step explanation:

To answer this question, we should first convert the amount of pounds Rick's cat weighs into ounces, so that both measurements are in the same unit. Since 1 pound is the same as 16 ounces, we can multiply 7 pounds by 16 ounces:

7 * 16 = 112

So, Rick's cat weighs 112 ounces, which is more than his neighbor's puppy, which only weighs 103 ounces. so for the first question, the answer is:

Yes, Rick's cat weighs more than the puppy.

And the second answer is:

Rick's cat weighs 112 ounces.

4x + 5y = 22
7x - 3y = -32

Answers

Answer:

x = -2

y = 6

Step-by-step explanation:

i multiplied the 1st equation by 3 and the 2nd by 5 to get the y-terms to zero out

   12x + 15y = 66

+  35x - 15y = -160

   47x = -94

x = -94/47

x = -2

substitute -2 for 'x' to solve for 'y':

4(-2) + 5y = 22

-8 + 5y = 22

5y = 30

y = 6

Answer:

To find the value of x we need to solve this equation

2x + 1 = 99

now ,taking constant to right side

2x = 99 - 1

2x = 98

x = 98/2

x= 49

The polynomial 2x³ + qx² + rx + 2 has a
factor (x - 1) and leaves a remainder of
12 when divided by (x - 2). Find the
constants q and r and hence the other
factors of the polynomial.​

Answers

Answer:

q = 1 , r = -5

other factors of polynomial:

(2x - 1) & (x + 2)

Step-by-step explanation:

In the first part, substitute x = 1 make it equal to 0.

Substitute x = 2 and make it equal to 12.

Rearrange both, until you have two linear equations.

Solve the set of simultaneous equation to find q and r .

Second part place the value of q and r to have the full polynomial.

Carry out long division, dividing the polynomial by the factor that's stated in the question (x - 1) and you will have a quadratic equation.

Factorise the quadratic equation to have the two other factors of the polynomial.
