-2x = x – 5
Answer:
x= 1.66 repeating
Step-by-step explanation:
Let's solve your equation step-by-step.
−2x=x−5
Step 1: Subtract x from both sides.
−2x − x = x − 5− x
−3x=−5
Step 2: Divide both sides by -3.
-3x/-3=-5/-3
Answer:
x=1.66 repeating

Answer:
Removing the -6 makes the average go from 4.1 to 5.2
Removing the -6 makes the median go from 4 to 5
Step-by-step explanation:
Average:
-6+3+3+3+3+5+6+6+8+10 = 41
41/10 = 4.1 (This is the mean/average)
If we remove -6, then:
3+3+3+3+5+6+6+8+10 = 47
47/9 = 5.2222 (This would be the new average)
So removing the -6 makes the average go from 4.1 to 5.2
Median:
The median of (-6+3+3+3+3+5+6+6+8+10) is between 3 and 5, so the median is 4.
Without -6, the median of (3+3+3+3+5+6+6+8+10) is 5.
So removing the -6 makes the median go from 4 to 5

Can you help me find the values of x and z?
Answer:
x = 96
z = 25
Step-by-step explanation:
x and 84 are supplementary angles.
this means that they add together to make 180.
using this, you can make the following equation:
x + 84 = 180
subtract 84 from both sides of the equation
x + 84 - 84 = 180 - 84
x = 180 - 84
x = 96
84 and 3z + 9 are vertical angles
vertical angles are equal.
using this, you can make the following equation:
84 = 3z + 9
subtract 9 from both sides of the equation
84 - 9 = 3z
75 = 3z
divide both sides of the equation by 3
75/3 = 3z/3
25 = z

Answer:
√3
Step-by-step explanation:
Factor 3 into its prime factors
3 = 3
Note that 3 is a prime number, it only has itself as a factor (that is on top of the trivial factor "1")
To simplify a square root, we extract factors which are squares, i.e., factors that are raised to an even exponent.
In our case however, all the factors are only raised to the first power and this means that the square root can not be simplified
The simplified SQRT looks like this:
sqrt (3)

If wrapping paper comes in packages of 300 cm2. How many packages will Sally need?
Answer:
she needs 3 packages
Step-by-step explanation:
the total area of the cd is 27 cm
so like
she needs to wrap 27 cm of area
because 0.5 cm by 14 cm by 12.5 cm added all together is 27
then
27 cm equals 10.6 inches
so now we need to find how many 300cm2 will fit into that 11 inch space
There are 0.00107639 square feet in a square centimeter.
but we want to know how many feet not square feet
0.00107639 × 27 =
0.02906253
2.906253
there are 2.906253 feet per suare foot
so 2.9 rounded up is 3
she needs 3 packages

Angle C and angle D are vertical angles with m angle C = -x + 26 and m angle D = 2x - 10.
What is m angle D?
Answer:
m∠D = 14
Step-by-step explanation:
According to the vertical angle theorem, both of these angles are congruent.
This means that they are equal (m∠C = m∠D) and we can solve for x:
m∠C = m∠D
-x + 26 = 2x - 10 (substitute in the equations)
-3x + 26 = -10 (subtract 2x from both sides)
-3x = -36 (subtract 26 from both sides)
x = 12 (divide both sides by -3)
Now that we know what x is, we can find m∠D by plugging it back into the equation:
m∠D = 2x - 10
m∠D = 2(12) - 10 (substitute the value for x in)
m∠D = 24 - 10
m∠D = 14
The value of the variable 'x' will be 12. Then the measure of the angle D will be 14°.
What is an angle?The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360 °.
Vertically opposite angle - When two lines intersect, then their opposite angles are equal.
Angle C and angle D are vertical angles with m∠C = -x + 26 and m∠D = 2x - 10.
∠C = ∠D
-x + 26 = 2x - 10
3x = 36
x = 12
Then the measure of the angle D will be
m∠D = 2x - 10
m∠D = 2(12) - 10
m∠D = 24 - 10
m∠D = 14°
The value of the variable 'x' will be 12. Then the measure of the angle D will be 14°.

The function f (x) = 6x + 13 defines a
sequence for x > 1. What are the first three
terms of the sequence?
Answer:
15, 21, 27
Step-by-step explanation:
Given the function :
f(x) = 6x + 13 ; which defines a sequence for x > 1
The first three terms of the sequence ;
x > 1 ;
Hence x = 2, 3, 4
The sequence :
f(2) = 6(2) + 3 = 12 + 3 = 15
f(3) = 6(3) + 3 = 18 + 3 = 21
f(4) = 6(4) + 3 = 24 + 3 = 27
