x =1.28
(x-2)/(x+1)=1/2 . find x
Answer:
x=5
Step-by-step explanation:
(x-2)/(x+1)=1/2, we use that a/b = c/d is the same as a*d = c*b
2*(x-2) = 1* (x+1), distribute multiplication over subtraction
2x -4 = x +1 , subtract x and add 4 to both sides
2x -x = 1 +4, combine like terms
x = 5
Answer: x = 5
Solve:
Given
(x - 2) / (x + 1) = 1/2
Cross multiply applied
1 (x + 1) = 2 (x - 2)
Expand parentheses and apply the distributive property
x + 1 = 2x - 4
Add 4 on both sides
x + 1 + 4 = 2x - 4 + 4
x + 5 = 2x
Subtract x on both sides
x + 5 - x = 2x - x
x = 5
Check:
Left-hand side = (x - 2) / (x + 1) = (5 - 2) / (5 + 1) = 3/6 = 1/2
Right-hand side = 1/2
1/2 = 1/2

dogs = 2/50* 100%
= 2*2% = 4%
so
= 10% + 4% = 14%

Pls help Im stuck Thx.
Step-by-step explanation:
First you divide the number of clicks by seconds.
36÷5=7.2
26÷3=8.6
Now you know how much clicks the bots do in 1 second
Bot#3= 7.2
Bot#4= 8.6
Now multiply by 10.
Bot#3= 72
Bot#4= 86
Bot#4 does more clicks in 10 seconds.

Answer:
The choose One
3n+m+2p
I hope I helped you^_^
Answer:
[tex] = 3n + m + 2p[/tex] (first option)
Step-by-step explanation:
[tex]4n - m + 3p + 2m - n - p[/tex]
[tex]4n - n = 4n - 1n = (4 - 1)n = 3n[/tex]
[tex]3n - m + 3p + 2m - p[/tex]

Tom makes a bet with his friend Bob. Bob wagers $100, but Tom decides to make him a deal. If Bob wins, Tom will pay him $100. If Tom wins, Bob will instead pay $1 for the first day, then every day for 10 days he must match the total amount paid so far.
For the first day, Bob will pay $1. The second day, he will pay an additional dollar, since he has only paid $1 thus far. The third day he will pay $2, the fourth $4, and so on.
If Bob has a 75% chance to win, which of the following is the closest to the amount of money Tom will make on average with this bet?

Step-by-step explanation:
The function is an illustration of a linear graph
The graph of the function has a slope of 3, and a y-intercept of -9
How to determine the equationThe equation is given as:
[tex]y - 3 = 3(x - 4)[/tex]
Open the bracket
[tex]y - 3 = 3x - 12[/tex]
Add 3 to both sides of the equation
[tex]y = 3x - 12+3[/tex]
Evaluate the like terms

An angle measures 46° more than the measure of its complementary angle. What is the
measure of each angle?
Answer:
Angle + the Complementary angle = 90 degrees. Let x be the measure of the angle under the question. Then the measure of the Complementary angle is (x+46) degrees, and you have this equation x + (x+46) = 90, or 2x+ 46 = 90, or 2x = 90 - 46 = 44. Then x =  = 22. The given angle has the measure of 22 degrees. The complementary angle is 90-22 = 68 degrees. Check. 68 - 22 = 44 degrees. Correct !!

BRAINLIEST, PLEASE!
Step-by-step explanation:
A(1, 2) B(0, -1) C(3, -2)
The distance between A and B is:
3^2 + 1^2 = c^2
9 + 1 = c^2
c = 10^1/2
The distance between B and C is:
1^2 + 3^2 = c^2
1 + 9 = c^2
c = 10^1/2
The distance between C and A is:
4^2 + 2^2 = c^2
16 + 4 = c^2
c= 20^1/2
Since AB and BC are the same, but AC isn't, the triangle is isosceles.

Help please. Domain ASAP
Answer:
x ≥ -1
Step-by-step explanation:
The domain is all the possible x-values of the function.
Reading from left to right, the first x-value is x = -1 (which is included because the dot is filled in.) From there, the graph goes to the right, towards infinity.
So x is greater than or equal to -1.

If you are performing the following translation (x,y) --> (x + 3, y -4) Determine how that would change the original ordered pair (10, 9). Select the new ordered pair after the Translation. (answer choices below)
(7, 9)
(10, 4)
(3, 10)
(13, 5)
Answer:
(13, 5 )
Step-by-step explanation:
The translation
(x, y ) → (x + 3, y - 4)
Means add 3 to the x- coordinate and subtract 4 from the y- coordinate, so
(10, 9 ) → (10 + 3, 9 - 4 ) → (13, 5 )

solve 4m plus 2n equals 5n for m.
Answer:
m = (3/4) n
Step-by-step explanation:
4m + 2n = 5n
The subtraction property of equality states that we can subtract 2n from both sides to isolate the m and its coefficient to get
4m = 3n
The division property of equality states that we can divide 4 from both sides to isolate only the m (we divide by 4 because anything divided by itself equals 1) to get
m = (3/4) n

The midpoint of AB is M(3, 1). If the coordinates of A are (1, -1), what are the
coordinates of B?
Answer:
(5,3)
Step-by-step explanation:
using the variable n write an algebraic expression for a number increased by 6
The answer you are looking for is simply just n+6.
Solution/Explanation:
If you use the variable "n" to write an algebraic expression, for a number increased by 6, you must write it like this:
n+6.
And, also, increase obviously means the same thing as adding.
So, therefore, "n" stands for the number in this algebraic expression, and if you add 6 to that number "n," it must be n+6.
So, therefore, the final answer is n+6.
I hope that this has helped you. Enjoy your day, and take care!
