Answer:

63

Step-by-step explanation:

x = # in ones place

y = # in tens place

x + y = 9

y = x - 3

substitute:

x + x-3 = 9

2x - 3 = 9

2x = 12

x = 6

y = 3

Choose the correct simplification of the expression (2ab5)3. (1 point) Question 8 options: 1) 8ab15 2) 8a3b8 3) 5a3b15 4) 8a3b15
d1i1m1o1n [39]

Answer:

4). 8a^{3}b^{15}

Step-by-step explanation:

The Given expression is that,

(2ab^{5})^{3}

On simplifying,

(2ab^{5})^{3} = (2ab^{5} )(2ab^{5}) (2ab^{5})

= (2^{3} ) * (ab^{5})^{3}

= (2×2×2) × (ab^{5} × ab^{5} × ab^{5})

= 8a^{3}b^{15}

Thus, <u>option 4</u> i.e.  8a^{3}b^{15} is the correct simplification of the given expression.

Use synthetic division to solve (x^3 + 1) ÷ (x – 1). What is the quotient?
timurjin [86]

Answer:

(x^{2} +x+1)(x-1)+2

Step-by-step explanation:

The synthetic division can be used to divide a polynomial function by a binomial of the form x-c, determining zeros in the polynomial.

step 1:  Establish the synthetic division, placing the polynomial coefficients in the first row (if any term does not appear, assign a zero coefficient) and to the extreme left the value of c.

1 |     1   0   0   1

step 2: Lower the main coefficient to the third row.

1 |     1   0   0   1

       1

Step 3: Multiply 1 by the main coefficient 1.

1 |     1   0   0   1

            1

       1

step 4: Add the elements of the second column.

1 |     1   0   0   1

            1

       1    1

step 5: Then repeat step 4 until the constant term 1 is reached.

1 |     1   0   0   1

            1    1    1

       1    1   1     2

step 6: Enter the quotient and remainder

quotient:  x^{2} + x + 1

remainder:  2

Solution:   x^{2} + x + 1 (x+1)  + 2

Solve for x<br><br><br><br> Please help
adoni [48]

Step-by-step explanation:

\frac{x}{x + x + 6}  =  \frac{9}{30}

\frac{x}{2x + 6}  =  \frac{9}{30}

30x = 9(2x+6)

30x = 18x+54

30x-18x = 54

12x = 54

x = 54/12

= 27/6
