Write simultaneous equations to describe the situation below, solve using substitution, and fill in the blanks.Alexa just became a personal trainer and is finalizing her pricing plans. One plan is to charge €61 for the initial consultation and then €32 per session. Another plan is to charge €66 for the consultation and €27 per session. Alexa realizes that the two plans have the same cost for a certain number of sessions. How many sessions is that? What is that cost?

For blank sessions, the cost is € blank on either plan.

Answers

x - the number of sessions
y - the cost

The system of equations:
y=61+32x \ny=66+27x

The solution:
y=61+32x \ny=66+27x \n \n\hbox{substitute 61+32x for y in the 2nd equation:} \n61+32x=66+27x \n32x-27x=66-61 \n5x=5 \ \ \ |/ 5 \nx=1 \n \ny=61+32x \ny=61+32 * 1 \ny=61+32 \ny=93 \n \n(x,y)=(1,93)

For 1 session, the cost is €93 on either plan.

uarts = ____ cups

Answers

10 quarts = 40 cups Explanation: Each quart is equal to 2 pints. So 10 multiplied by 2 is 20 pints. Each pint is equal to 2 cups. So 20 multiplied by 2 is 40.
There are 4 cups in a quart so 4 x 10 would be 40 cups. Hope i helped

Answer:

Angle of depression from C to T measures approximately 20.52^o

Step-by-step explanation:

To start, we use triangle DTA to find the length of the side AT, making use of the tangent function:

tan(23^o)=(AT)/(28\,m) \nAT=tan(23^o)\,* 28\,m\nAT=11.89\,m

Now we need to find the size of the rectangular land diagonal:

diagonal=√(28^2+15^2)=31.76\,m

With this information, we can now find the measure of angle "C" (depression angle from C to T), using the triangle ACT:

tan(C)=(opposite)/(adjacent) \ntan(C)=(11.89)/(31.76)\nC=arctan((11.89)/(31.76))\nC=20.52^o
