Write an algebraic expression for the statement.The income earned at $ 10.91 per hour for w hours....
Alja [10]
This is a "rate of pay" problem.  The amount earned is equal to the (rate of pay) times the (number of hours worked).  

Let the income be represented by "i".  Then the formula is i = ($10.91/hour)*w, where w is the number of hours worked and has the unit of measurement "hours."

olganol [36]

Answer:

the number of hours does sidney skate in all is 9.8 hours

Step-by-step explanation:

The computation of the number of hours does sidney skate in all is as follows:

= Last month + this month

= 1 \frac{1}{10} + 8 \frac{7}{10}\\\\= \frac{11}{10} + \frac{87}{10}\\\\= \frac{98}{10}

= 9.8 hours

Hence, the number of hours does sidney skate in all is 9.8 hours

I really need help with this equation as soon as possible :D
viktelen [127]
The subtraction sign in front of the second set of parenthesis changes the signs on the terms inside those parenthesis.  So this could be rewritten as  x-3x^4+2x^2+x^3-4x^6.  None of the exponents on the x are the same, so we will just express it in terms of descending powers of x.   -4x^6-3x^4+x^3+2x^2+x.   This is also the same as  4x^6+3x^4-x^3-2x^2-x  if you don't like to start with a negative.  Either one is correct.

At the theater, tickets for adults cost $4.75
shutvik [7]
X+y= 26 and 4.75x + 2.25y= 83.50

y=26-x( substitute this into second equation for y and solve for x)

4.75x + 2.25(26-x)= 83.50

4.75x + 58.5-2.25x= 83.50

x= 10

Now solve for y by substituting your answer for x

10+ y= 26

y=16

Therefore, 16 tickets were purchased for kids and 10 for adults.
