PLS HELP ME ASAP!!!!!!!!! ill give thanks, and five stars
Answer:
A
Step-by-step explanation:
The additive inverse property states that if we have a number a, then:
[tex]a+(-a)=0[/tex]
Here, we have the equation:
[tex]2x=542[/tex]
And we divide both sides by 2:
[tex]2x/2=542/2[/tex]
To acquire:
[tex]x=271[/tex]
So, we did not use the additive inverse property since we didn't add anything.
Instead, we used the division property of equality by dividing both sides by 2.
So, our answer is A.
And we're done!

what is the square root of -1?
Answer:
It might be weird but i is the answer and I don't know why exactly.
Step-by-step explanation:
I think it's because there is no real number when having a negative square.
Do all variable terms have a coefficient?
technically yes because even if you have a variable of just x, there is still a coefficient of 1
Explain why a +b= d.
Answer:
see explanation
Step-by-step explanation:
a + b + c = 180 ( sum of angles in a triangle )
c + d = 180 ( adjacent angles are supplementary ), thus
a + b + c = c + d ( subtract c from both sides )
a + b = d
The reason for the value of a+b being equal to d is because adjacent angles are supplementary.
First and foremost, it should be noted that a triangle has three sides and the sum of the angles in the triangle will be equal to 180°.
Therefore, based on the information given in the question, the solution will go thus:
a + b + c = 180°
Note that c + d = 180° since adjacent angles are supplementary.
Therefore, a + b + c = c + d
Collect like terms
a + b + c - c = d
a + b = d
Therefore, the equation has been proven and showed that a + b = d.

There are 504 calories in eight ounces of a certain ice cream. How many calories are there in one pound? \text{1 pound}= 1 pound= \,\,\text{16 ounces} 16 ounces Before you try that problem, answer the question below. How many ounces will you need to find the number of calories for?
Answer:
1,008 calories
Step-by-step explanation:
504 calories in eight ounces
How many calories are there in one pound
1 pound = 16 ounces
504 calories = 8 ounces
x calories = 1 pound
Recall, 1 pound = 16 ounces
504 calories : 8 ounces = x calories : 16 ounces
504 / 8 = x / 16
Cross Multiply
504 * 16 = 8 * x
8,064 = 8x
Divide both sides by 8
x = 8,064 / 8
= 1,008
x = 1,008 calories
Therefore, there are 1,008 calories in one pound

v=bnj solve for b
this is in algebra 2
Answer:
The solution is [tex]b=\frac{v}{nj}[/tex]
Step-by-step explanation:
To solve an equation for a variable, state this variable with coefficient 1 on the left side and all the other terms on the right side
Ex: 2x + 6y = 10, solve for x
Subtract 6y from both sides to move it to the right side2x + 6y - 6y = 10 - 6y2x = 10 - 6yDivide each term on both sides by 2 to make the coefficient of x = 1[tex]\frac{2x}{2}=\frac{10}{2}-\frac{6y}{2}[/tex]x = 5 - 3yLet us use the same way to solve the given equation for b
∵ v = bnj
→ Switch the two sides to put b on the left sides
∴ bnj = v
∵ n and j multiplied by b
→ Divide both sides by nj to move them from the left side to the right side
∴ [tex]\frac{bnj}{nj}=\frac{v}{nj}[/tex]
∴ [tex]b=\frac{v}{nj}[/tex]
The solution is [tex]b=\frac{v}{nj}[/tex]

Solve this system by substitution, 50 points!
-x -y -z = -8
-4x +4y +5z = 7
2x+2z=4
Show steps please!
Answer:
:
Solve:
-X - Y - Z =-8
- 4X +4Y +5Z=7
2X + 2Z =4 is the same as x + z = 2. Thus, z = 2 - x.
Subst. 2 - x for z in the 1st and second equations.
-X - Y - Z =-8 becomes -x - y - (2 -x) = -8
- 4X +4Y +5Z=7 becomes -4x + 4y + 5(2-x) = 7
Now we have 2 equations in only 2 unknowns. Let's simplify them!
-x - y - 2 + x = -8 which becomes -y = -6, or y = 6
-4x + 4y + 10 - 5x = 7 which becomes -9x + 4y = 7 - 10 = -3
Now substitute 6 for y in this last equation: -9x + 4(6) = -3, or
-9x + 24 = -3, or
-9x = - 27 => x = 3
Then x = 3, y = 6 and z = 2 - x, or z = 2-3, or z = -1.
The solution is (3, 6, -1). Check it!!

the area of a rectangular window is 6216 cm^2. if the length of the window is 84 cm, what is it's width?
Answer:
The answer is 74 cmStep-by-step explanation:
The area of a rectangle = length × width
Since we are finding the width
We have
[tex]width = \frac{area}{length} \\ [/tex]
From the question
area = 6216 cm²
length = 84 cm
The width is
[tex]width = \frac{6216}{84} \\ [/tex]
We have the final answer as
74 cmHope this helps you
Tickets to the zoo cost $12 for adults (x) and $8 for children (y). The school has a budget of $240 for the field trip.
Use your equation and/or your graph to calculate how many children will be able to go to the zoo if 8 adult tickets are purchased.
Equation=
12x+8y=240
Answer:
y=18
Step-by-step explanation:
The equation for this problem would be c=12x+8y (c being the total cost of tickets) If you plug in 240 for c, the equation is 240=12x+8y. From there, you know that 8 adult tickets are purchased, so we can plug 8 in for x. So 240=12(8)+8(y) Since the goal is to solve for y, you just simplify the equation.

3p + q - 8p + 4q
Answer:
-5p + 5q or 5q - 5p
Step-by-step explanation:
For this equation, you would combine like terms to get the answer.
So you would combine 3p and -8p and get -5p. (whenever combining like terms, the variable always takes the sign in front of it that's why 8p is negative)
And then combine q and 4q which would make 5 q because a single letter always has a 1 in front of it regardless of it is shown or not.
Then you would set the equation up as it is shown above
