Answer is C
Let x = the number you need to find.
4x + (-5) = 2x + 11
You finish.
Answer:
B) 2600
Step-by-step explanation:
Set up a proportional equation and solve:
220/300=x/3545
(220)(3545)=300x
779900=300x
2599.666=x
2600=x
Your best estimate is B) 2600
Answer:
what was the question
Step-by-step explanation:
The equation:
p x + q = 46 x + 23
p x - 46 x = 23 - q
x ( p - 46 ) = 23 - q
x = ( 23 - q ) / ( p - 46 )
This equation has infinitely many solutions for :
23 - q = 0 and p - 46 = 0
or: q = 23 and p = 46
Answer : A ) p = 46 & q = 23
