Evaluate 7-5p+3q when p= 1 and q =7

23

Step-by-step explanation:

7-(5*1)+(3*7)

7-5+21

2+21

23

23

Step-by-step explanation:

If p=1, then 5p would be 5 x 1

5 x 1 = 5

And if q = 7, then 3q would be 3 x 7.

3 x 7 = 21

With that in mind, we have 2+21

2+21=23

The answer is 23.

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
