-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

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°.

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

To find:
The given equation in terms of r if [tex]\dfrac{x}{r}=-3[/tex].
Solution:
Given that,
[tex]\dfrac{x}{r}=-3[/tex]
[tex]x=-3r[/tex]
We have,
[tex]y=x^2+6x-1[/tex]
Substitute x=-3r in the above equation.
[tex]y=(-3r)^2+6(-3r)-1[/tex]

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

I NEED HELP ASAP PLEASE!! -4(w+1)=-24 w= what?
GiveN:
-4(w + 1) = -24wWhat to do?
We have to solve for wStep-by-step explanation:
For solving the Equation, we need to simplify it first. Expanding the parentheses.
⇒ -4w - 4 = -24 w
Shifting -24 w to the LHS to isolate m and shifting 4 to the RHS[tex].[/tex]
⇒ -4w + 24w = 4
⇒ 20w = 4
Dividing the equation by 20, So that we will get w in the LHS of the equation.
⇒ w = 4/20
⇒ w = 1/5
The required value of w is 1/5.

A scientist needs 10 liters of a 20% acid solution for an experiment, but she only has a 5% solution and a 40% solution. To the nearest tenth of a liter, about how many liters of the 5% and 40% solutions should she mix to get the solution she needs?
9514 1404 393
Answer:
4.3 L of 40% solution5.7 L of 5% solutionStep-by-step explanation:
Let x represent the number of liters of 40% solution in the mix. Then the total amount of acid in the mix is ...
0.40x +0.05(10-x) = 0.20(10)
0.35x +0.5 = 2.0
0.35x = 1.5
x = 1.5/0.35 ≈ 4.3 . . . . liters of 40% solution
10-x = 10 -4.3 = 5.7 . . .liters of 5% solution

Answer:

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)
