In the balance scale/equation analogy, what should you write in the blank on the right side of the equation in order to balance the scale for the following equation? 2(x + 1) = 2x + ______
(x + 1)
4
x
2
Answer:
Option D: 2 is the correct answer.
Step-by-step explanation:
Given equation is:
2(x + 1) = 2x + ______
For balancing the equation, the variables and constants must be same on both sides of the equation.
Simplifying 2(x+1) gives us 2x+2
As 2x is already there, we will add 2 with it in the equation.
Hence,
Option D: 2 is the correct answer.

Rita is a nurse her regular rate is $14.62 per hour. She is paid double-time (two times the hourly rate) for holidays. During one week she worked 36 regular hours plus 8 holiday hours.
The amount of money when she worked one week she worked 36 regular hours plus 8 holiday hours will be $760.24.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Rita is a nurse her regular rate is $14.62 per hour. She is paid double-time (two times the hourly rate) for holidays.
Then the amount of money when she worked one week she worked 36 regular hours plus 8 holiday hours will be
⇒ $14.62 x 36 + $14.62 x 2 x 8
⇒ $526.32 + $233.92

illustrates whather the two ratios are equal or not using cross 3/27, 1/9
Answer:
They are equal
Step-by-step explanation:
Given
[tex]\frac{3}{27}\ and\ \frac{1}{9}[/tex]
Required
Determine if they are equal
We start by equating both:
[tex]\frac{3}{27} = \frac{1}{9}[/tex]
Cross Multiply
[tex]3 * 9 = 1 * 27[/tex]
[tex]27 = 27[/tex]
Because both sides of the equation are equal, then the ratios are equal

Answer:
1. -1/3
2. 3/4
3. 2
4. -9/0
5. 1
6. -6/4
Step-by-step explanation:
1. To find this numbers slope you have to go over and up (or down depending on where the line is going) You go over once and down three times to the next dot. This is why it is negative, because you go down
2. Same as number one you go over (Run) and up (Rise) . You go over 3 times and up 4. This makes it positive, since you are going up.
3. Stick to this formula (y2-y1)
(x2-x1)
-4-8
0-6 =-12/-6 =2
4. Same as 3
1-8
5-5 = -9/0
5. Go over 1 and up 1 this will equal 1/1 which is just 1.
6.
-2-4
-6-2 =-6/-8
This can be simplified down to -3/-4

C.
23%
D.
37%
Answer:
Step-by-step explanation:
B 15%
Answer: The correct answer is D) 37%
Step-by-step explanation:
We can use our binomial model equation with all the relevant information to solve this problem simply. We just need to dissect the problem a bit to find relevant information. We know that out of 16 batteries in a pack (the number of trials in this case) we want to find the possibility of 1 of them (the number of successes) to be defective with a defective rate of 5% or 0.05. We simply input the data into our binomial formula given and solve for our answer of 37% I hope this answer has been of use.

what is the acceleration of a car that has a mass of 300 kg and 1200N
what is the acceleration of a car that has a mass of 300 kg and 1200N
Answer:
well the acceleration produced will be
[tex]4ms { - }^{2} [/tex]
Step-by-step explanation:
the formula used here is
F = m × a
(where m = mass , a = acceleration and f = force )
so,
=》1200 N = 300 kg × a
=》a = 1200N ÷ 300 kg
=》a = 4 metre per second square
