Answer:
4r- 21
Step-by-step explanation:
4 - r= r and r+ 21/= R21 and Simplified Is -4 and R21
Step-by-step explanation:
25m + 10b = 400
not enough info to solve for m or b. but that's the equation you would use.

Answer:
x = 25.6
Step-by-step explanation:
As we can see, this is a right triangle, so there are known relationships
well to start we have to know the relationship between angles, legs and the hypotenuse
α = 43
a: adjacent = x
o: opposite
h: hypotenuse = 35
sin α = o/h
cos α = a/h
tan α = o/a
we see that it has (angle, adjacent, hypotenuse)
cos α = a/h
cos 43° = x / 35
cos 43° * 35 = x
25.59 = x
if we want to round to the nearest tenth
x = 25.59 = 25.6
