x = number of pounds of type A coffee

y = number of pounds of type B coffee

Keisha made 151 pounds of the blend, so x+y = 151 which solves to y = -x+151

The second equation is 5.65*x + 4.55*y = 791.55

since 5.65*x represents the total cost of just type A alone and 4.55*y represents all of type B only. The two subtotals combine to a grand total of 5.65*x + 4.55*y which is set equal to the final cost 791.55

5.65*x + 4.55*y = 791.55

5.65*x + 4.55*(y) = 791.55

5.65*x + 4.55*(-x+151) = 791.55 <--- replace y with -x+151

5.65*x - 4.55x + 687.05  = 791.55

1.10x + 687.05  = 791.55

1.10x+687.05-687.05=791.55-687.05 <- subtract 687.05 from both sides

1.10x = 104.5

1.10x/1.10 = 104.5/1.10 <--- divide both sides by 1.10

x = 95

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

ok thats very interesting
