95

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

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
