a truck holds at most 20.000 lb. there are 18 boxes on the truck. eaxh weighs 750 lb. how many additional boxes can the truck hold? graph the solution show your work
Answers
Answer:
6
Step-by-step explanation:
750 x 18 = 13,500lb
Remaining weight until truck is full = 20,000 - 13,500 = 6,500
6,500 ÷ 750 = 8.66666666667
You cannot have 8.666... of a box and therefore, the answer = 6
The number of additional boxes the truck can hold is n = 8 boxes
What are Linear Equations?An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.
The linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution
On a graph, a linear equation forms a straight line. On a graph, a nonlinear equation produces an S-curve, a bell curve, or another nonlinear shape.
Given data ,
Let the number of additional boxes the truck can hold be n
Now , the equation is
The truck holds at most 20,000 lb
The initial number of boxes in the truck = 18 boxes
The weight of each box = 750 lb
So , the total weight of the each box = 18 x 750 = 13,500 lb
Now , the linear equation is
The total weight of the each box + 750n ≤ 20,000
On simplifying , we get
13,500 + 750 ( n ) ≤ 20,000
Subtracting 13,500 on both sides , we get
750n ≤ 6500
Divide by 750 on both sides , we get
n ≤ 8.667
So , the number of additional boxes i 8 boxes
Hence , the linear equation is solved

What is the solution to the system of equations represented by these two lines?
The solution of a system is a point that the lines have. In other words, it is the point where the two lines intersect.
The lines intersect at (2, 3), so the answer is the last option.
There is also a more reliable method of solving. In order for the two lines to be equal, their equations (1.5x = y and y= -0.5x + 4) must be equal.
So,
1.5x = -0.5x + 4
Add 0.5x to both sides.
2x = 4
x = 2.
Now, find how much y must be when x equals two. (You can use either equation to do this)
y = 1.5 * 2
y = 3.
Thus, the coordinates are (2, 3).

Step-by-step explanation:
Given
[tex]\frac{1}{2}[/tex] (x + 12) = 4x - 1 ( multiply through by 2 to clear the fraction )
x + 12 = 8x - 2 ( subtract x from both sides )
12 = 7x - 2 ( add 2 to both sides )
14 = 7x ( divide both sides by 7 )
2 = x
There is one solution to the equation, that is x = 2

The statement - "Five less than the product of 6 and a number equals 7" can be modelled as (6x - 5 = 7).
What is expression?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is the statement -
"Five less than the product of 6 and a number equals 7"
We can model this statement as an expression as follows. Let the number be {x}. Then, we can write that -
6x - 5 = 7
Therefore, the statement - "Five less than the product of 6 and a number equals 7" can be modelled as (6x - 5 = 7).

Can anyone help me out and summarize this, please: That’s his problem. It’s not your problem. There isn’t a tactful way to deal with somebody who has temper fits and throws a little fit about everything that’s about them. He doesn’t get to decide how you run your family. “I’m sorry. I can’t come. I don’t have the money, and we don’t borrow money. You’ve got to have a little more communication about things than that. Sorry.”
Furious is furious, and such it is. I can’t control other people’s temper fits. I can’t fix that for them. They have to deal with their own self on that. You can’t do it otherwise. It’s that simple.

Answers
Answer:
I think the summary is about the guy saving money or trying to find a job for money? orrrrr, its about what you can and cant control, like people's emotions and choices, sorry if this isn't right!!!!
Step-by-step explanation:
Answer:
Managing kids can be a challenge. Some days keeping the peace while keeping your cool seems impossible. But whether you're reacting to an occasional temper flare-up or a pattern of outbursts, managing your own anger when things get heated will make it easier to teach kids to do the same.
To help tame a temper, try to be your child's ally — you're both rooting for your child to triumph over the temper that keeps leading to trouble.
While your own patience may be frayed by angry outbursts, opposition, defiance, arguing, and talking back, it's during these episodes that you need your patience most. Of course you feel angry, but what counts is how you handle that.
Reacting to kids' meltdowns with yelling and outbursts of your own will only teach them to do the same (and actually is associated with an increase in children's negative behaviors). But keeping your cool and calmly working through a frustrating situation lets you show — and teach — appropriate ways to handle anger and frustration.
Let's say you hear your kids fighting over a toy in the other room. You have ignored it, hoping that they would work it out themselves. But the arguing turns into screaming and soon you hear doors slamming, the thump of hitting, and crying. You decide to get involved before someone gets really hurt.
By the time you arrive at the scene of the fight, you may be at the end of your own rope. After all, the sound of screaming is upsetting, and you may be frustrated that your kids aren't sharing or trying to get along. (And you know that this toy they're fighting over is going to be lost, broken, or ignored before long anyway!)
So what's the best way for you to react? With your own self-control intact. Teaching by example is your most powerful tool. Speak calmly, clearly, and firmly — not with anger, blame, harsh criticisms, threats, or putdowns.
Of course, that's easier said than done. But remember that you're trying to teach your kids how to handle anger. If you yell or threaten, you'll model and ingrain the exact kinds of behavior you want to discourage. Your kids will see that you're so angry and unable to control your own temper that you can't help but scream — and that won't help them learn not to scream.

Answer:
the domain of f(x) is set of all real numbers except 3/2

Since the denominator cannot equal 0, 2x - 3 ≠ 0

x ≠ 3/2
Any real number can replace x in the numerator.
So, the domain of f(x) is all real numbers except 3/2
The domain of the given function is required.
The domain is (-∞,3/2),(3/2,∞)
