Answer:
a)x=5; b)x=4
Step-by-step explanation:
a) 4x-3=2x+7
=>4x-2x=7+3
=>2x=10
=>x=5 [divide both by 2]
b)2x+6=7x-14
=>7x-2x=6+14
=>5x=20
=>x=4 [divide both by5]

Answer:
The statement is not reasonable.
Step-by-step explanation:
Josefina gave away 130% of her stamp collection.
We cannot give more than what we have.
lets understand it mathematically.
suppose i have x stamp.
according to question, i have to give 130% of my stamp collection
130% of x = 130/100 x = 1.3x
so, i have to given 1.3x stamp while i do have only x stamp which does not make any sense.
maximum i can give is x stamp.
x stamp in percentage of my total stamp collection which is also x will be
= x/x*100 = 100%
Thus, maximum one can give is 100% of what he has.
Thus, we can say that Josefina gave away 130% of her stamp collection is not reasonable.
Answer:
Explanation and problem 1 solved below.
Step-by-step explanation:
The quadrants are numbered this way:
Quadrant 1: upper right
Quadrant 2: upper left
Quadrant 3: lower left
Quadrant 4: lower right
Signs of coordinates in the quadrants:
x-coordinate is positive in Q1 and Q4
x-coordinate is negative in Q2 and Q3
y-coordinate is positive in Q1 and Q2
y-coordinate is negative in Q3 and Q4
1. (-1, 5)
x is negative, so it is Q2 or Q3
y is positive, so it is Q1 or Q2
The quadrant in common is Quadrant 2
Answer: quadrant 2
