Given that x = 8, y = 2, and z = 3, the equation 2x = 3yz is false.
An expression is a number, variable or the combination of both put together by operation symbols while an equation is a statement that shows that two expressions are equal and is separated by an equal sign "=".
To check if the equation 2x = 3yz is true when x = 8, y = 2, and z = 3, plug in or substitute the value of each variable to the equation and evaluate.
2x = 3yz
2(8) = 3(2)(3)
16 ≠ 18
Since 16 is not equal to 18, the given values do not satisfy the equation, then the statement is not true.

2. Which graph represents the solution
of 6 + 3y < 9 or 4y > 3y + 2?
Help please!!!!!
Answer: B.
Step-by-step explanation:
First, we will solve both of these given inequalities for x by isolating the variables.
Given:
6 + 3y < 9
Subtract 6 from both sides of the equation:
3y < 3
Divide both sides of the equation by 3:
y < 1
--
Given:
4y > 3y + 2
Subtract 3y from both sides of the equation:
y > 2
Now, our given inequalities are y < 1 and y > 2. These inequalities are easier to view on the graph. We see that these are not equal to (≥ or ≤), so we will have open circles.
First, we will graph y < 1. We will plot an open circle at y = 1 and then shade to the left of it. Net, we will graph y > 2. We will plot an open circle at y = 2 and then shade to the right of it. This leaves us with answer option B.

A solution consisting of 90 mg of dopamine in 20 mL of solution is administered at a rate of 8 ml/hr.
A solution of 150 h is administered at a rate of 8 ml / hr.
We express the answer in terms of mg/hr m g / h r
90 mg dopamine / 20 ml = 4.5 mg/ml
4.5 mg/ml * 8 ml/h = 36 mg/h
90 mg * 1 h / 36 mg= 150 h to administer -- using the inverse of 90 mg per 1 hour and cancelling mg in numerator and ml denominator.
Hence, 150 h is administered at a rate of 8 ml / hr.

Logic puzzle help solve pleaseeeeeeeee
Answer:
Many challenging questions do not involve numerical or geometrical considerations but call for deductive inferences based chiefly on logical relationships. Such puzzles are not to be confounded with riddles, which frequently rely upon deliberately misleading or ambiguous statements, a play on words, or some other device intended to catch the unwary. Logical puzzles do not admit of a standard procedure or generalized pattern for their solution and are usually solved by some trial-and-error method. This is not to say that the guessing is haphazard; on the contrary, the given facts (generally minimal) suggest several hypotheses. These can be successively rejected if found inconsistent, until, by substitution and elimination, the solution is finally reached. The use of various techniques of logic may sometimes prove helpful, but in the last analysis, success depends largely upon that elusive capacity called ingenuity. For convenience, logic problems are arbitrarily grouped in the following categorie

This statement is False:
"21- to 24-year-olds in the us have the lowest percentage of drivers in fatal crashes with bac levels of .08% or higher."
What do deadly crashes entail?A traffic collision, also known as a motor vehicle collision, car accident, or car crash, happens when a vehicle strikes another vehicle, a pedestrian, an animal, road debris, or another immovable object, like a tree, pole, or a structure.
Exactly what is a nonfatal accident?An injury that is not fatal under this approach is one that results from prolonged exposure to an outside force or substance (mechanical, thermal, electrical, chemical, or radiation) or from submersion. Both deliberate and inadvertent bodily harm may occur.
In a collision, what areas of the body are struck first?Severe injuries are most frequently dealt to the neck, followed by the head, chest, legs, and abdomen/pelvis, for passengers riding on the side of the automobile that was impacted. For those riding in vehicles on the contralateral side of the car, head injuries are most common, followed by chest injuries.

The drawing that creates a line of reflection that takes the point A to point B is; D: Draw a line parallel to line AB.
How to create a line of reflection
A line of reflection is a line that lies in a position between two identical mirror images so that any point on one image is the same distance from the line as the same point on the other flipped image.
Let us look at the given options;
A) Draw the perpendicular bisector of segment AB; A perpendicular bisector will NOT create a line of reflection that takes point A to point B but rather it will divide the line AB in two equal parts
B) Draw a line through B perpendicular to segment AB; A line through B perpendicular to segment AB will NOT Create a line of reflection that takes point A to point B
C) Draw the line passing through A and B;
A line passing through A and B will NOT create a line of reflection that takes point A to point B but rather will create Line A and B again and not its reflection
D) Draw a line parallel to line AB;
A line parallel to line AB will create a line of reflection that takes point A to point B because a parallel line never meet thereby creating the direct imagery of Line AB.

Incredible Skating has a family special this weekend: You rent skates for $5
and pay $1 an hour for skating per person. Write an equation, where h
represents the number of hours and C represents the total cost.
Answer:
c=5+1h
Step-by-step explanation:
The equation for where h represents the number of hours and C represents the total cost is C = 5 + nh.
Given that the skates were rented for $5 and pay $1 an hour for skating per person.
We need to write an equation, where h represents the number of hours and C represents the total cost.
To calculate the total cost (C) for a family with h hours of skating, you would need to consider the cost of renting skates ($5) and the cost of skating per person per hour ($1 per person per hour).
Let n be the number of people in the family.
The equation for the total cost (C) can be expressed as follows:
C = 5 + nh
The $5 is added to the equation as a one-time cost for renting skates, which is the same for any number of people.
nh represents the cost for the number of people (n) skating for h hours, at the rate of $1 per person per hour.
The cost per person is multiplied by the number of hours they skate.
Hence the required equation is C = 5 + nh.

You can find the net force F on an object
by using the formula F = ma, where m is
the mass of the object in kilograms and
a is its acceleration in meters per second
squared. What is the mass of an object
that has a net force of 65 kg m/s² and an
acceleration of 5 m/s²?
Answer: m = 13 kg
Step-by-step explanation:
This question gives us the formula to use. We will plug-in the values we know and solve for the unknown (mass).
Given:
F = ma
Plug-in known values:
(65 kg m/s²) = m(5 m/s²)
Divide both sides of the equation by 5 m/s²:
The m/s² unit cancel out, so we are left with kg.
m = 13 kg
The mass of the object is 13 kg.

-3(x+5)=-(3x+15) solve for x
Step-by-step explanation:
Simplifying
-3(x + 5) = -1(3x + 15)
Reorder the terms:
-3(5 + x) = -1(3x + 15)
(5 * -3 + x * -3) = -1(3x + 15)
(-15 + -3x) = -1(3x + 15)
Reorder the terms:
-15 + -3x = -1(15 + 3x)
-15 + -3x = (15 * -1 + 3x * -1)
-15 + -3x = (-15 + -3x)
Add '15' to each side of the equation.
-15 + 15 + -3x = -15 + 15 + -3x
Combine like terms: -15 + 15 = 0
0 + -3x = -15 + 15 + -3x
-3x = -15 + 15 + -3x
Combine like terms: -15 + 15 = 0
-3x = 0 + -3x
-3x = -3x
Add '3x' to each side of the equation.
-3x + 3x = -3x + 3x
Combine like terms: -3x + 3x = 0
0 = -3x + 3x
