simplify 1/2 (4x+2) - (-2x)
Answer:
4x + 1 is the simplified expression
Step-by-step explanation:
We have to use order of operations in order to solve. We basically need to simplify it with multiplication and addition.
The first step involves mulitplication and distribution property:
1) Do 1/2(4x + 2). If you use distribution property, it would be 1/2(4x) + 1/2(2)
2) Then use multiplication 1/2(4x) is 2x (since 4 multiplied by 1/2 is 2) and 1/2(2) is 1 (since 1/2 times 2 is 1).
Bow the expression is almost simplified as it is:
2x + 1 -(-2x)
The 2nd stop involves addition. First we have to know what -(-2x) means. Think of the negative sign on the outside as -1. This way it would be:
3) -1(-2x), and then do -1(-2) which is 2 since a negative times a negative is positive.
4) Now we know that -(-2x) is the same as: + 2x.
5) So the expression would be 2x + 1 + 2x. Combine like terms ( 2x and 2x) and you will get 4x + 1.
Hope you understood this and have a nice day!

Step-by-step explanation:
a). [tex]\frac{5\pm\sqrt{-4}}{3}[/tex] = [tex]\frac{5}{3}\pm \frac{\sqrt{-4}}{3}[/tex]
= [tex]\frac{5}{3}\pm\frac{2\sqrt{(-1)} }{3}[/tex]
= [tex]\frac{5}{3}\pm\frac{2i}{3}[/tex] [Since, i = [tex]\sqrt{(-1)}[/tex]]
b). [tex]\frac{10\pm\sqrt{-16}}{2}[/tex] = [tex]\frac{10}{2}\pm \frac{\sqrt{-16}}{2}[/tex]
= [tex]5\pm \frac{4\sqrt{-1}}{2}[/tex]
= 5 ± 2i [Since, i = [tex]\sqrt{(-1)}[/tex]]
c). [tex]\frac{-3\pm \sqrt{-144}}{6}[/tex] = [tex]-\frac{3}{6}\pm \frac{\sqrt{-144}}{6}[/tex]

A girl’s name is ""Olivia Summer"" so her initials are OS. How many people need to be in an auditorium to ensure that at least 4 people in that room have the same pair of initials?
Answer:
2704
Step-by-step explanation:
My probability math is a bit rusty, but here's my reasoning.
Assuming that it is a 1/26 chance someone has the same first inital as you (which isn't true, some initials are more prominent than others) and a 1/26 chance that somone has the same last inital as you (also not true) then it would be a 1/26 x 1/26 chance to find someone with the same first and last inital as you
To find 4 people in a room with the same inital would be 26 x 26 x 4, or 2704. If we are counting Olivia as a fifth person, then it would be 26 x 26 x 5, or 3380.
Each box is 20 inches long, 30 inches wide, and 20 1/2 inches in hieght.
What is the volume of the box?
Answer:
Volume = 12,300
Step-by-step explanation:
20 x 30 = 600
600 x 20.5 =12300
Answer:
Volume of the box is length ×breadth×height
[tex]20 \times 30 \times 20 \frac{1}{2} \\ = 600 \times \frac{41}{2} \\ = 12300[/tex]
12300 inches cube is the right answer.The length of a rod correct to the nearest cm is 75 cm.
Calculate the greatest possible length of 12 such rods.
Answer:
The greatest possible length is 900 cm
Step-by-step explanation:
Here, we want to calculate the greatest possible length of 12 of those rods
Firstly, we assume that the rods have a length of 75 cm
This will give the greatest possible length of each of the rods
So the possible length of 12 of these will be
12 * 75 = 900 cm

Chirstine baked a pumpkin pie. She ate 1/6 of the pie. Her brother ate 1/3 f it ang gave leftovers to his friends. What fraction of the pie did he give to his freinds?
Answer:
1/2
Step-by-step explanation:
Let the total pie be 2
She ate 1/6
Her brother ate 1/3
If she gave her Friend the remaining, the fraction of the amount her friend collected is expressed as:
1-(1/6+1/3)
= 1-((1+2)/6)
= 1-3/6
= 1 - 1/2
=1/2
Hence the fraction she gave her friend is 1/2

Mom buys a rectangular rug with an area of LaTeX: 7\frac{1}{6}7 1 6 square meters. The length of the rug is LaTeX: 3\frac{1}{3}3 1 3 meters. What is the width of the rug?
Answer:
2 3/20 metres
Step-by-step explanation:
Area of the rug = Length × width
Given
Area = 7 1/6 metres = 43/6 m
Length = 3 1/3 metres = 10/3 m
Required
Width
From the formula
A = LW
W = A/L
Substitute the given values
W = 43/6÷10/3
W = 43/6×3/10
W = 43/2 ×1/10
W = 43/20
W = 2 3/20 m
Hence the width of the rug is 2 3/20 metres

Is 6 plants in 1 square yard and example of a unit rate or a rate?
Answer:
Its an example Unit rate becuase theres the #1 in it and its constant
Step-by-step explanation:
A rate is more like a ratio of 2 different number
3:6
or
9:18
When these are simplified you’ll get 1 in one of the 2 numbers but then it would be a unit rate
Rate= no #1
Unit rate= Defined as a number 1

Answer:
a) 13%
b) 45%
c) 16%
Step-by-step explanation:
To calculate what percentage is one number (a) of another (b), you have to divide a by b and then multiply result by 100. In this case number of students with grade A is 4, total number of students is 31, therefore 4/31 * 100 = 12.9%. Rounding it to the nearest percentage will give you 13.
Just repeat the same steps for the remaning questions.

Find the intercept
5x+3y=15
X-intercept:
Y-intercept:
Answer:
X: x=3-3/5y
Y: y=5-5/3x
Step-by-step explanation:
For X:
-3y on both sides will result in:
5x=15-3y
5x/5=15/5-3y/5 (divide 5 on both sides)
x=3-3/5y
For Y:
-5x on both sides will result in:
3y=15/3-5x/3 (divide 3 on both sides)
y=5-5/3x

if 15 sandwiches are sold for 12 Rand what would 12 sandwiches be sold for
Answer:
$9.60 for 12 sandwiches
To solve the problem we will calculate the cost of 1 sandwich first.
The cost of 12 sandwiches is 9.6 Rands.
Given
15 sandwiches are sold for 12 Rand
What is the value of 1 sandwich?We know the cost of 15 sandwiches is 12 Rand, therefore,
[tex]\text{Cost of 1 Sandwich} = \dfrac{\rm 12\ Rand}{\rm 15\ Sandwich}[/tex]
[tex]\text{Cost of 1 Sandwich} = \dfrac{12}{15} = 0.8\ \rm Rand/Sandwich[/tex]
What is the cost of 12 Sandwiches?The cost of 12sandwiches can be calculated using the cost of 1 sandwich,
[tex]\text{Cost of 12 Sandwiches} = \text{Cost of 1 sandwich} \times 12[/tex]
[tex]= 0.8 \times 12 = 9.6\ \rm Rand[/tex]
Hence, the cost of 12 sandwiches is 9.6 Rands.

What is an equation of the line that passes through the points (7,-6) and (3.-6)2
Answer:
y=-6
Step-by-step explanation:
y=mx+b, b is the y-intercept, m is slope
slope (m)= rise/run
(-6--6)/(7-3)=
0/4=
0
So plug it in.
y=(0)x+b
y=b
But what is y?
Pick either coordinate and plug the y-value into the equation y=b.
Now you have -6=b
So the final equation is y=-6.
It doesn't matter what the x value is, it's going to be multiplied by 0, the y coordinate on this line will always be -6.
Alternatively, you can plot it out, both (7,-6) and (3,-6) have the same y coordinate, therefore you can immediately see that the slope=0 because it's just a horizontal line.
