x^2y^2 +9xy^2-xy-27y-6

Step-by-step explanation:

(xy+9y+2) (xy-3)

Each term of second bracket will be multiplied with the terms of first bracket

= xy(xy+9y+2) -3(xy+9y+2)

= x^2y^2+9xy^2+2xy-3xy-27y-6

=x^2y^2+9xy^2-xy-27y-6

makvit [3.9K]

Answer: C. There are four groups of three tens and six ones

Step-by-step explanation:

From the options,

A. Three groups each have three tens and 4 ones.

Three tens and 4 ones equal: = (3 × 10) + (4 × 1) = 30 + 4 = 34

Therefore, 34 ÷ 3 is incorrect.

B. There are three groups of five tens and 9 ones in each group.

Five tens and 9 ones will be equal to:

= (5 × 10) + (9 × 1)

= 50 + 9 = 59

Therefore, 59 ÷ 3 is incorrect

C. There are four groups of three tens and six ones.

Three tens and six ones equal:

= (3 × 10) + (6 × 1)

= 30 + 6 = 36

Therefore, 36 ÷ 4 is correct

D. There are three groups of five tens and nine ones in each group.

Five tens and nine ones will be equal to:

= (5 × 10) + (9 × 1)

= 50 + 9 = 59

Therefore, 59 ÷ 3 is incorrect

Therefore, the correct option is C.

Answer:

$\$17.59\ per\ hour$

Step-by-step explanation:

we know that

The Susan's hourly wage, must be equal at least to the sum of her monthly household expenses divided by the number of hours worked at month

Remember that

$1\ year=52\ weeks\\1\ year=12\ months$

She works 40 hours per week

$40(52)=2,080\ hours\ per\ year$

$2,080/12=\frac{520}{3}\ hours\ per\ month$

<em>Find out the monthly household expenses</em>

Sum all the expenses

Rent+ Monthly Bills+Entertainment and Food+Savings

substitute the values

$\$875+\$1,276+\$648+\$250=\$3,049$

Find out the hourly wage

$\$3,049:\frac{520}{3}\ hours=\$17.59\ per\ hour$
