Answer: Larry thought of the number 14
Step-by-step explanation:
Let the number be represented by x
Such that when added with 1 becomes x+1
Multiplied by 2 becomes 2(x+1)
divided by 3 gives 2(x+1)/3
Upon subtraction with 4, we have
2(x+1)/3 -4=6 as the equation
Solving
2(x+1)/3 -4=6
2(x+1)/3=6+4
2(x+1)/3=10
2(x+1)=3x10
2(x+1)=30
2x+2=30
2x=30-2
2x=28
x=28/2
x=14
Answer:
d = all real numbers
Step-by-step explanation:
-9d-8= -4 (d + 2) - 5d
-9d - 8 = -4d - 8 - 5d
-9d - 8 = -9d - 8
0d - 8 = -8
0d = 0
d = all real numbers
0.40 is actually 2/5.
2/5=4/10=8/20=16/40
How did I create all of these fractions?
Quite simple... I multiplied each fraction by 1... What do you mean?
2/5*2/2=4/10
2/2 is one by the way.
4/10*2/2=8/20.
You get the idea?
