The denominator contains negative exponents. Using the negative exponent rule, multiply the denominator by -1 and then reverse the fraction and multiply.

The denominator becomes x^3y^4

The problem then becomes -3x^6y^4 times x^3y^2

When multiplying exponents add them together:

The final answer is -3x^9y^6

a computer and printer a totoal cost $1132 the cost of the computer is three times the cost of the ptinter

zavuch27 [327]

Use a system of equations

C+P=1132
3P=C

Substitute C in first equation as
3P+P=1132
Simplify
4P=1132
Solve
P=1132/4
P=283

NOW SOLVE FOR C SUBSTITUTING P VALUE IN FIRST EQUATION

C+283=1132
C=1132-283
C=849

Printer = 283$
Computer = 849$

Rachel reads 1/5 of the pages of a book plus 12 pages on the first day.

kkurt [141]

Answer:

Let's say that the whole book have 5a pages.

First day: a + 12

Second day: (4a)1/4+15= a + 15

Third day: (1/3)[ 4a - (a+15)] +18= a + 13

Forth day: 70

So we get this:

(a + 12) + (a + 15) + (a + 13) + 70 = 5a

a + 12 + a + 15 + a + 13 + 70 = 5a

3a + 110 = 5a

3a - 5a = -110

-2a = -110

a = 55

5a = 5(55) = 275

So the total pages are in the book is:

275 pages
