Answer:

D. 32 3/5

Step-by-step explanation:

4 1/5 * 7  2/3

Change each number to an improper fraction

4 1/5 = (5*4+1)/5 = 21/5

7 2/3 = (3*7+2)/3 = 23/3

Multiply these together

21/5 * 23/3

483/15

Change this back to a mixed number

15 goes into 483 32 times (32*15 =480) with 3 left over

32 3/5

Answer:

The answer to this problem is C. 32 1/5.

Step-by-step explanation:

Step 1: Multiply the whole number by the denominator then add the numerator to it. Apply this to both fractions individually.

21/5 *  23/3  

Step 2: Multiply the fractions.

21/5 * 23/3 = 483/15  

Step 3: Simplify the fraction into the simplest form.

483/15 simplifies to 32 3/15 and then simplifies to its simplest form 32 1/5.

Answer:

32m^4 + 12m^3 = 4m^3(8m + 3)  ---------->correct

40m^6 - 4 = 4(10m^6 - 1) ---------->correct

Step-by-step explanation:

32m^4 + 12m^3 = 4m^3(8m + 3)  ---------->correct

40m^6 - 4 = 4(10m^6 - 1) ---------->correct

15m^3 - 6m = 3m(5m^2 - 2) , so it's not correct if answer : 3m(5m^2 - 6m)

6m^2 + 18m = 6m(m + 3) , so it's not correct if answer : 6m^2(1 + 3)

Which system is equivalent to 3x^2 - 4y^2 = 25
Archy [21]

For this case we have the following system of equations:

3x ^ 2 - 4y ^ 2 = 25\\-6x ^ 2 - 2y ^ 2 = 11

We can write a system of equivalent equations.

For this, it is enough to multiply one of the two equations by a scalar.

Multiplying the equation 1 by 2, we have:

6x ^ 2 - 8y ^ 2 = 50

Therefore, the new system of equations is:

6x ^ 2 - 8y ^ 2 = 50\\-6x ^ 2 - 2y ^ 2 = 11

Answer:

A system that is equivalent is:

D) 6x ^ 2 - 8y ^ 2 = 50\\-6x ^ 2 - 2y ^ 2 = 11
