Which value, when placed in the box, would result in a system of equations with infinitely many solutions?
Whitepunk [10]
-10. One type of system of equations that results in infinite solutions is one where both sides of the equation are exactly equal. Here, setting the second equation equal to -10 becomes 2y - 4x = -10. This can be rearranged into 2y = 4x - 10. Dividing everything by 2 results in y = 2x - 5, which is exactly what the first equation is. Substituting one equation into another, we get 2x - 5 = 2x - 5, which is a true statement for all values of x.

Kay and Allen sell cell phones. Last month Kay sold 17 more cell phones than Allen. Together they both sold 117 cell phones. How
cricket20 [7]

Answer:

Step-by-step explanation:

K = A + 17

K + A = 117

A + 17 + A  = 117

2A + 17 = 117

2A = 117 - 17

2A = 100

A = 100/2

A = 50 <=== what Allen sold

K + A = 117

K + 50 = 117

K = 117 - 50

K = 67 <==== what Kay sold
