16*2=32
32-.25(1.5 teaspoons) =31.75
31.75 ounces of pepper
Start by factoring -24
6* -4 = -24
7*-3 = -24
you are looking for factors that add to give the middle coefficient +5
7 and -3 add to give 5 and multiply to give -24
( x + 7)(x - 3) = 0
this gives the solution for x, because one or both (x + 7) and/or (x - 3) would have to be zero for them to multiply and be zero.
x = -7
x = 3
Answer:x=8/3 ; y=13/3
Step-by-step explanation: to find the intersection point or the solution of the graph, you need to equate these equations 1) y=5x-9 2) x+y=7 => y=7-x x equating the equations 5x-9=7-x => 6x=16 => x=8/3 ; y=13/3
Answer:
Step-by-step explanation:
Let x = the number of $20 bills.
Then x + 6 = the number of $5 bills and
20x + 5(x + 6) = 455
x = 17 = number of $20 bills
x + 6 = 17 + 6 = 23 = number of $5 bills
