Given:
The different equations in the options.
To find:
The equation which have infinitely many solutions.
Solution:
In option A,
[tex]2x+8=2(x+8)[/tex]
[tex]2x+8=2x+16[/tex]
[tex]8=16[/tex]
This statement is false for any real value of x. So, the given equation has no solution.
In option B,
[tex]3x+2(x-2)+6=5x+2[/tex]
[tex]3x+2x-4+6=5x+2[/tex]
[tex]5x+2=5x+2[/tex]
[tex]2=2[/tex]
This statement is true for all real value of x. So, the given equation has infinitely many solutions.
In option C,
[tex]x+7=7[/tex]
[tex]x=7-7[/tex]
[tex]x=0[/tex]
This equation has only one solution, i.e., x=0.
In option D,
[tex]x=0[/tex]
This equation has only one solution, i.e., x=0.
Only equation [tex]3x+2(x-2)+6=5x+2[/tex] has infinitely many solutions. Therefore, the correct option is B.

Petra takes $15 to the roller skating rink to spend on skates and food. Suppose it costs $4.75 to rent roller skates. Define a variable and write an inequality to represent the amount of money Petra can spend on food. Then solve the inequality and interpret the solution. Explain your reasoning.
The amount of money Petra can spend on food must be less than $10.25.
InequalityInequality is an expression used to how the non equal comparison of two or more numbers and variables.
Let x represent the amount of money Petra can spend on food. From the question
x + 4.75 ≤ 15
x ≤ 10.25
The amount of money Petra can spend on food must be less than $10.25.

What is the sum of the interior
angles of a polygon that has 19
sides?
[?] degrees
Please helpppp!!!!!
Answer:
[tex]\boxed {\boxed {\sf 3060 \textdegree}}[/tex]
Step-by-step explanation:
The sum of a polygon's interior angles is found using this formula:
[tex]180 \textdegree (n-2)[/tex]
where n is the number of sides. This polygon has 19 sides.
[tex]n=19[/tex]
[tex]180 \textdegree*(19-2)[/tex]
[tex]180 \textdegree*(17)[/tex]
[tex]3060 \textdegree[/tex]
The sum of the interior angles is 3,060 degrees.

A 13 feet ladder is placed 5 feet away from a wall. The distance from the ground straight up to the top of the wall is 13 feet Will the ladder the top of the wall?
Answer:
the answer is
a^2 + b^2 = c^2
5^2 + b^2 = 13^1
25 + b^2 = 169
b^2 = 144
b = 12
or
The ladder is the hypotenuse, and the two legs are distance from the wall and height of the wall. If it is moved 5 feet away, it will reach 12 feet high, for 5^2+12^2=13^2.

Answer: x - 4
The missing dimension of the prism is A
because the volume of the rectangular prism equals the product of the sides, we have:
V = (x - 1)(x - 3)A
but V = x³ - 8x² + 19x - 12
=> x³ - 8x² + 19x - 12 = (x - 1 )(x - 3)A
⇔ x²(x - 1) - 7x(x - 1) + 12(x - 1) = (x - 1)(x - 3)A
⇔ (x² - 7x + 12)(x - 1) = (x - 1)(x - 3)A
⇔ (x² - 3x - 4x + 12)(x - 1) = (x - 1)(x - 3)A
⇔ (x - 3)(x - 4)(x - 1) = (x - 1)(x - 3)A
⇒ A = x - 4

Help please! Will give brainly
Answer:
C
Step-by-step explanation:
First we need to find W. You can do that by dividing 47.25 by 5.25.
47.25 / 5.25 = 9
So W = 9.
Now we do both equations to see which one is correct.
Equation A: 3/4 × 9 = 6 3/4, which is true.
Equation B: 9 - 10.24 = -1.24, which is also true.
Therefore, both equations give you the same solution, C.

2 (x + 3 )= -x
Answer:
-2 =x
Step-by-step explanation:
2 (x + 3 )= -x
Distribute the 2
2x+6 = -x
Subtract 2x from each side
2x+6-2x = -x-2x
6 = -3x
Divide each side by -3
6/-3 = -3x/-3
-2 =x
Answer:
x = -2
Step-by-step explanation:
2 (x + 3) = -x
2x + 6 = -x
- 6 -6
2x = -x - 6
+x + x

Find the zeros of the function.
Enter the solutions from least to greatest.
g(x) = -10x2 + 490
lesser =
greater x =
Answer:
Lesser = -490
Greater x = 100x
Step-by-step explanation:
The zeros is basically the opposite numbers to make the equation equal to 0.
We have -10x^2(I believe it's a power)
and we have + 490
so,
-10x^2 = -100x
So the opposites to make those is:
+ 100x because, -100x + 100x = 0
and -490 because, 490 - 490 = 0.

Find the percent change 50 is decreased to 14.
Answer:

Answer:
AB=24.5
Step-by-step explanation:
5x+7=7x
7=2x
x=3.5
7(3.5)=24.5
what is the percent decrease of 2,400 to 2,100?
#You times it with ×100 to get the percentage
#Part of the number/total number
2400 - 2100 = 300
300/2400 × 100 = 12.5%
So the percentage decreased is 12.5%
How do you solve this equation: 80x =
