Answer: $15
There are about 4 weeks in a month, so if you spend $60 per month, you would spend 1/4 of that every week.
60/4= $15
Answer:
x=8 & x=3
Step-by-step explanation:
We want to get the (x)s all on one side.
add 5x to each side
Since x^2 is x•x and 5x is 5•x then we can change the formula to
x(x+5)=8
then seperate that
x=8
x+5=8
subtract 5 from each side
x=3.
The solutions are 8 and 3.
The trig functions that you need to deal with are
Sine
Cosine
Tangent
Cotangent
Cosecant
Secant
You need to write a single expression using all six trig functions such that the value of the expression equals 3.
To make this as simple as possible, the first thing I would do is look up the values of these functions and identify which ones are equal to either 1/2 or 1.0 or 2.0
sin(30º) = 1/2
sin(90º) = 1
cos(0º) = 1
cos(60º) = 1/2
tan(45º) = 1
csc(30º) = 2
csc(90º) = 1
sec(0º) = 1
sec(60º) = 2
cot(45º) = 1
If we only had to use three trig functions (sin, cos, tan), one possibility is
tan(45º) + cos(0º)/sin(30º) = 1 + 1/(1/2) = 1 + 2 = 3
noticed how I chose one each of the required functions and the operations so that the result = 3.
Now it is up to you to figure out how to combine all six trig functions so that they equal zero. There are many possibilities for you to choose from..
Since they are equal to 90 degrees. (complimentary angles)
6x-11+7x+10= 90
Combine like terms.
13x-1= 90
Add one to both sides.
13x= 91
x= 7
Plug that into the b.
7(7)+10
49+10
59
I hope this helps!

Answer:(-5,-6)
Step-by-step explanation:
Solve for one variable then solve for the other. Don’t worry you will get a big fraction before you get to the whole number.
