Answer: x-1/6
Step-by-step explanation:
Let A represent the amount Ann contributed, Z represent Zoe's contribution, and J represent Jim's contribution toward the present.
Ann (A): A
Zoe (Z): A = Z - 12 → Z = 12 + A
Jim (J): A = J - 16 → J = 16 + A
A + Z + J = 154
(A) + (12 + A) + (16 + A) = 154
3A + 28 = 154
3A = 126
A = 42
Ann (A): A = 42
Zoe (Z): Z = 12 + A = 12 + 42 = 54
Jim (J): J = 16 + A = 16 + 42 = 58
Answer: Ann=42, Zoe=54, Jim=58
Answer: x= 3
Step-by-step explanation:
15x-25+2=22
15x-25=25
15x=50
x=3.333333
x=3
Answer:
B
Step-by-step explanation:
you can use foil and the graph,
because you can see (in the graph) that the lines intersect at 1 and 4.
just use foil to help figure out which matches the slope.
something else (the normal way) is find which 2 numbers equal to the last coefficient, in this case it can be
-2 and -2, 2 and 2, 4 and 1 or -4 and -1, multiply them and if they make up the last coefficient, and added it equals the second coefficient it is correct.
