Answer:

The required expression, in terms of x for the total number of financial calculators bought is given by : 200 - x

Step-by-step explanation:

Total number of calculators = 200

Price of each scientific calculator = R 89

Price of each Financial calculator = R 599

Let number of scientific calculators bought be x

So, number of financial calculators bought = 200 - x

Let total cost of buying 2000 calculators be R y

Hence, Expression for total cost of buying 200 calculators :

y = 89·x + 599·(200 - x)

And the required expression, in terms of x for the total number of financial calculators bought is given by : 200 - x

Let the number of financial calculators purchased = "y"

So, x + y = 200

200 - x = total number of financial calculators purchased

If the angles are represented in degrees, find both angles: \cos(3x+13)=\sin(2x+42) cos(3x+13)=sin(2x+42)
Sphinxa [80]

Answer:

cos34°

sin56°

Step-by-step explanation:

Sin(2x+42)= sin90-(3x+13)

Sin(2x+42) = sin(90-13-3x)

Sin(2x+42) = sin(77-3x)

2x + 42 = 77-3x

5x. = 35

X = 7

If x = 7

cos(3x+13) = cos((3*7)+13)

cos(3x+13) = cos(21+13)

cos(3x+13)= cos34

And

sin(2x+42) = sin((2*7)+42)

sin(2x+42)= sin (14+42)

sin(2x+42) = sin56
