First lets combine terms.
<span>4x 2 + 5x + 2 = 2x 2 + 7x – 1 subtract the left side from right side
</span>
(4x 2- 2x 2) + (5x - 7x) + (2 + 1)=0 then combining
2x 2 - 2x + 3 =0 now we can use the quadratic formula
<span>
</span>a=2, b=-2 c=3
see attached and plug them in
Simplifying
x + 0.7 = 1 + -0.2x
Reorder the terms:
0.7 + x = 1 + -0.2x
Solving
0.7 + x = 1 + -0.2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '0.2x' to each side of the equation.
0.7 + x + 0.2x = 1 + -0.2x + 0.2x
Combine like terms: x + 0.2x = 1.2x
0.7 + 1.2x = 1 + -0.2x + 0.2x
Combine like terms: -0.2x + 0.2x = 0.0
0.7 + 1.2x = 1 + 0.0
0.7 + 1.2x = 1
Add '-0.7' to each side of the equation.
0.7 + -0.7 + 1.2x = 1 + -0.7
Combine like terms: 0.7 + -0.7 = 0.0
0.0 + 1.2x = 1 + -0.7
1.2x = 1 + -0.7
Combine like terms: 1 + -0.7 = 0.3
1.2x = 0.3
Divide each side by '1.2'.
x = 0.25
Simplifying
x = 0.25
I only know 1 way.
Answer: 2 4/15 months
Step-by-step explanation:
From the question, we are informed that a wagon train traveled from Missouri to Wyoming in 1 2/3 months and from Wyoming to Utah in 3/5 month.
The number of months that it will take the wagon train to travel from Missouri to Utah will be:
= 1 2/3 + 3/5
The common lowest multiple is 15
= 1 10/15 + 9/15
= 1 19/15
= 1 + 1 4/15
= 2 4/15 months
It will take they train 2 4/15 months to travel from Missouri to Utah.
Answer:
It is given that red dot is about halfway between 12 and 13.
Draw a number line.Mark points on it on as 1,2,3,.....12,13,...20.
Label 12 as point M and label 13 as N.
Mid point of MN=
=25/2
=12.5
Mark 12.5 as T.
MT =NT
The Red dot is at point N at a distance of 12.5 units from the origin.
