Answer:
x = -2/5
Step-by-step explanation:
x + 3 - 2x = 4x + 5
Combine like terms
-x + 3 = 4x + 5
Subtract 4x from both sides
-5x + 3 = 5
Subtract 3 from both sides
-5x = 2
Divide both sides by -5
x = -2/5
The solution to the equation x + 3 - 2x = 4x + 5 is x = -2/5.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To solve for x in the equation x + 3 - 2x = 4x + 5,
We can follow these steps:
Simplify both sides of the equation by combining like terms.
Starting with the left-hand side:
x + 3 - 2x = -x + 3
Now we can rewrite the equation as:
-x + 3 = 4x + 5
Add x to both sides of the equation to isolate the x term on one side:
-x + x + 3 = 4x + x + 5
Simplifying:
3 = 5x + 5
Subtract 5 from both sides of the equation:
3 - 5 = 5x + 5 - 5
Simplifying:
-2 = 5x
Divide both sides of the equation by 5 to solve for x:
-2/5 = x
Therefore,
The solution to the equation x + 3 - 2x = 4x + 5 is x = -2/5.

Evaluate f(x) = 2x - 7 when x = 8.
Answer:
9
Step-by-step explanation:
Substitute 8 in place of x
f(x) = 2*8-7
f(x) = 9
Answer:
9
Step-by-step explanation:
plug in 8 where x is so it would look like
2(8)-7 = 9
do 2 *8 first which is 16
then do 16-7 which gives you 9
The times that a cashier spends processing individual customers' orders are independent random variables with mean 3.5 minutes and standard deviation 3 minutes. Find the number of customers n such that the probability that the orders of all n customers can be processed in less than 2 hours, is approximately 0.1. (Round your answer to the nearest integer.)
Answer:
26 customers
Step-by-step explanation:
First: determine the z score from standard normal probability table with an indicative area of 0.1
Z-score from probability table = - 1.28
mean = 3.5 minutes
std = 3 minutes
next determine the Z-score based on the information given in the question
Z = ( std - mean ) / processing time
= ( 3 - 3.5 ) / 2 = -0.25
Finally determine the number of customers
N = [tex](\frac{-1.28}{-0.25} )^2[/tex] = 1.6384 / 0.0625 = 26.21 ≈ 26 customers
which best describes a rectangle with diagonals that are perpendicular
Answer: If a parallelogram has diagonals that are perpendicular, it is a rhombus. … This definition can also be stated as: A square is a quadrilateral that is also a rectangle and a rhombus.
Step-by-step explanation:
If x = 7 units, y = 2 units, and h = 9 units, find the area of the trapezoid shown above using decomposition.
A.
81 square units
B.
99 square units
C.
63 square units
D.
72 square units
Answer:
A) 81 sq units
Step-by-step explanation:
Area of a trapezoid = one-half of height multiplied by the sum of the bases (the bases are the parallel sides)
the problem gives us all the values we need:
height = 9
smaller base is 'x' which is 7
larger bases is 2y+x which is 2(2)+7 = 11
A = 1/2·(9)(7+11)
= 1/2·9·18
= 9·9 which is 81 sq units

3. Is XY Tangent to circle Z?
Y
12 X
(20
Z
18
Answer:
XY is a tangent
Step-by-step explanation:
Given
[tex]XY = 12[/tex]
[tex]WY = 20[/tex]
[tex]WZ = 8[/tex]
Required
Is XY a tangent?
XY is a tangent if:
[tex]WY^2 = XY^2 + WX^2[/tex]
Because XY should make a right angle at point X with the circle
Where
[tex]WX = 2 * WZ[/tex]
So, we have:
[tex]WY^2 = XY^2 + WX^2[/tex]
[tex]WY^2 = XY^2 + (2*WZ)^2[/tex]
[tex]WY^2 = XY^2 + (2WZ)^2[/tex]
[tex]WY^2 = XY^2 + 4WZ^2[/tex]
This gives:
[tex]20^2 = 12^2 + 4*8^2[/tex]
[tex]400 = 144 + 256[/tex]
[tex]400 = 400[/tex]
Yes, XY is a tangent
