Answer:

x = 7/6

Step-by-step explanation:

Solve for x:

35/74 (4/3 + 21/(5 x)) - 4/5 = 23/15

Bring 35/74 (4/3 + 21/(5 x)) - 4/5 together using the common denominator 1110 x:

(2205 - 188 x)/(1110 x) = 23/15

Cross multiply:

15 (2205 - 188 x) = 25530 x

Expand out terms of the left hand side:

33075 - 2820 x = 25530 x

Subtract 25530 x + 33075 from both sides:

-28350 x = -33075

Divide both sides by -28350:

Answer:  x = 7/6

Tim Hortons is hiring and offers $200 every week plus $5 per hour. McDonalds offers $300 every week plus $2 per hour. State the
Bogdan [553]

Answer: After working for 33 \frac{1}{3} hours a week

Step-by-step explanation:

     Let us write equations to represent these two places. Let x be hours worked and y be money earned.

   Tim Hortons:

$200 + $5x = y

    McDonalds:

$300 + $2x = y

    Now, to find the conditions of which Tim Hortons is the better employer (on the basis of money earned) we must find the interval that Tim Hortons pays more. This can be found by setting up another equation, or by graphing. I have shown both. <em>See attached for the graph</em>.

$200 + $5x > $300 + $2x

$5x > $100 + $2x

$3x > $100

x > \frac{100}{3}

x > 33.3334

    Tim Hortons is the better employer after an employee has worked for 33 \frac{1}{3} hours a week.

balandron [24]
Distance of A from cliff = 1500·arctan(30°) ≅ 723.5 ft

distance of B from cliff = 723.5+1000√3 ≅ 2455.6 ft
tanθ = 2455.6/1500 = 1.637
θ = arctan(1.637) ≅ 58.6°
angle of depression = 90-θ ≅ 30°
