Answer:
24 weeks.
Step-by-step explanation:
25x = 600
divide both sides by 25 to get:
x = 24
Answer:
The system of equations will have an infinite number of solutions.
Step-by-step explanation:
i) when we arrive at a solution of a linear system with two equations and two
variables and the solution of the equation does not give the value of any
variable but rather is in the form of an identity like the one given, that is
-6 = -6, then we can say that the two equations are exactly the same and
that the system of equations will have an infinite number of solutions.
80% of 90 would be bigger because:
80/100*80=72
Answer:24x
Step-by-step explanation:
Answer:
1 hour
Step-by-step explanation:
Lea's speed = 22km/hr
Trevon's speed = 43km/hr in a direction opposite Lea's
How long does Trevon needs to drive before they are 65km apart.
Note : both took at the same time and in opposite direction.
Recall : speed = distance / time
Distance = speed * time
Distance between them = 65km
Let Trevon's distance = D2 = 43 * t
Lea's distance = D1 = 22 * t
t is the same since they both left at the same time.
D2 + D1 = 65
43t + 22t = 65
65t = 65
t = 65/65
t = 1 hour
