I'll give you a hint. <u><em>You had to used pemdas stands for: p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtracting.</em></u>
First you had to calculate with parenthesis first.
Then you add and subtract from left to right.
Final answer 
Hope this helps!
And thank you for posting your question at here on brainly, and have a great day.

M is your answer, because the tangent intersects the circle at point M.
So M is correct.
The measures of the legs of the right triangle are:
X = 2.5
Y = 4.3

How to find the values of x and y?</h3>
In the image, we can see a right triangle with a hypotenuse with a value of 5, and a known angle.
To find the values of X and Y (the legs of the triangle) we can use the two relations:
Sin(a) = (opposite cathetus)/(hypotenuse)
Cos(a) = (adjacent cathetus)/(hypotenuse)
In this case, we have:
a = 30°
hypotenuse = 5
opposite cathetus = X
adjacent cathetus = Y.
Replacing that in the relations we get:
Sin(30°) = X/5
Sin(30°)*5 = X = 2.5
cos(30°) = Y/5
cos(30°)*5 = Y = 4.3

Answer:
50
Step-by-step explanation:
so half a dollar is $0.50. We multiply by 9, which gives you $4.50. But the customer gave $5, so they would get $0.50 back.
It helps to imagine the variable a sort of as a unit. Like with 5 minus 12 lemons, it has no bearings on the addition/subtraction here.
Factor out a and subtract.
