Answer:

x=14

Step-by-step explanation:

2(3x-4)=5x+6

first get rid of the parentheses by multiplying the  2

6x-8 = 5x+6

put like terms on one side of the equation. Start with the 5x, move it to the left side

(6x-8)-5x = (5x+6)-5x

x-8 = 6


Again, put like terms on one side of the equation. Move the 8 to the right side

(x-8)+8 = 6+8

=> x = 14


B)

4x - 3 = 2(x-1)

Start again by getting rid of the parentheses to make it a clean equation... aka distribute the 2:

4x-3 = 2x - 2

Move the like terms to one side of the equation. Start with x.. move 2x to the left:

(4x-3)-2x = (2x-2)-2x

=> 2x-3 = -2

Move the like terms to one side of the equation.Now move the -3 to the other side:

(2x-3)+3 = -2+3

=> 2x=1

Lastly, divide by 2 on both sides to find out what x is:

(2x)/2=1/2

=> x = 1/2


..so no, Charlie was incorrect.

Answer:

x=14

In the second line, he changed the sign on the 2

Step-by-step explanation:

2(3x-4) = 5x+6

Distribute the 2

6x-8 = 5x+6

Subtract 5x from each side

6x-5x -8 = 5x-5x+6

Add 8 to each side

x-8+8 = 6+8

x=14


b.  4x-3 = 2(x-1)

Distribute

4x-3 =2x-2    He changed the sign on the 2

Subtract 2x from each side

4x-2x -3 = 2x-2x-2

2x-3 =-2

Add 3 to each side

2x-3+3 =-2+3

2x =1

Divide by 2

2x/2 =1/2

x=1/2

Chain complete 40% of her homework on Monday and 2/3 on Tuesday if she started her homework on Monday what fractional part of he
kotykmax [81]

Answer:

1/5

Step-by-step explanation:

For Monday

The fraction of homework Chain completed =

40% of her homework

= 40% = 40/100

= 2/5

For Tuesday

The amount of home work left =

= 1 - 2/5

3/5

The fraction of homework Chain completed on Tuesday = 2/3

= 2/3 Of 3/5

= 2/3 × 3/5

= 2/5

Let the total complete homework be represented by 1

Hence:

The Fractional part of her homework left for her to complete after Tuesday =

1 - (2/5 + 2/5)

Lowest common denominator is 5

= 1 - (2 + 2/5)

= 1 - (4 /5)

= 1/5

B. If some amount of water contains 1400 oxygen atoms, how many hydrogen atoms does it contain?
Genrish500 [490]

Answer:

B: 2800 hydrogen atoms

C: 6760 hydrogen atoms

D: y=amount of oxygen atoms*2

Step-by-step explanation:

B: We know the formula for water is H2O. SO that means that there is 2 hydrogen atoms and 1 oxygen atom. So there is 2 times the amount of hydrogen atoms so we can do 1400*2=2800, So there is 2800 hydrogen atoms in the water.

C: Same thing as B. 3380*2=6760

D: y=amount of oxygen atoms*2. Because there is one oxygen atom and two hydrogen atoms so 1*2=2.

A lawn mower is pushed a distance of 100 ft. Along a horizontal path by a constant force of 60 lbs. Yhe handle of the lawn mower
olga2289 [7]
For this case we have the following equation:
 w = || F || • || PQ || costheta
 Where,
 || F ||: force vector module
 || PQ ||: distance module
 costheta: cosine of the angle between the force vector and the distance vector.
 Substituting values:
 w = (60) * (100) * (cos (45))
 w = 4242.640687 lb.ft
 Answer:
 
The work done pushing the lawn mower is: 
 w = 4242.640687 lb.ft

What is the first quartile (Q1) of the data set?
KATRIN_1 [288]
Sequence = 40, 45, 48, 51, 59, 62, 69, 74

Median = 51+59 / 2 = 55
First quartile = 40, 45, 48, 51 
So, it would be: 45 + 48 / 2 = 46.5

In short, Your Answer would be Option C

Hope this helps!
