Which equation has infinitely many solutions? A) 4x + 3 3 = 4x + 5 B) 10x + 8 2 = 5x + 4 C) 8x − 5 3 = 2x − 2 D) 8x − 5 2 = 4x −
abruzzese [7]

Answer: If the left side and the right side of the equation are equal, the equations has  infinitely many solutions.

Step-by-step explanation:

The options are not clear, so I will give  you a general explanation of the procedure you can use to solve this exercise.

The Slope-Intercept form of the equation of a line is the following:

y=mx+b

Where "m" is the slope and "b" is the y-intercept.

For this exercise you need to remember that, given a System of Linear equations, if they are exactly the same line, then the System  of equations has Infinitely many solutions.

If you  have the following system:

\left \{ {{y=2x+1} \atop {y=\frac{12}{6}x+1}} \right.

You can simplify the second one:

y=2x+1

Then, both equations are the same line.

By definition you can also write the systemf making both equations equal to each other:

2x+1=2x+1

So, if the left side and the right side are equal, the equations has  infinitely many solutions.

78 is 15% of what #?
nirvana33 [79]
1. 78 = 0.15x
    78 / 0.15 = x
    520 = x.....so 78 is 15% of 520

2. | 3x - 2 | = 8                               | x + 1 | = 1

3x - 2 = 8      -(3x - 2) = 8            x + 1 = 1          -(x + 1) = 1
3x = 8 + 2      -3x + 2 = 8             x = 1 - 1           -x - 1 = 1
3x = 10           -3x = 6                  x = 0                 -x = 2
x = 10/3           x = -2                                             x = -2

ur answer is : x = -2

3. 3y - 4x + 5 = 0
    3y = 4x - 5
      y = 4/3x - 5/3
   slope = 4/3

How do you solve and simplify <br> 2/5+1/4+7/10=
Alchen [17]

Hello!

<em><u>Answer: ⇒ 27/20</u></em>

Step-by-step explanation:

\frac{8}{20}+\frac{5}{20}+\frac{14}{20}

Since the denominators are equal, then combine the fractions.

\frac{8+5+14}{20}

Add by the numbers.

8+5+14=27

=\frac{27}{20}

Hope this helps!

Thank you for posting your question at here on brainly.

Have a great day!
