Answer:
Solution for 7x-3=9x+5 equation:
x = -4
Step-by-step explanation:
Simplifying
7x + -3 = 9x + 5
Reorder the terms:
-3 + 7x = 9x + 5
Reorder the terms:
-3 + 7x = 5 + 9x
Solving
-3 + 7x = 5 + 9x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-9x' to each side of the equation.
-3 + 7x + -9x = 5 + 9x + -9x
Combine like terms: 7x + -9x = -2x
-3 + -2x = 5 + 9x + -9x
Combine like terms: 9x + -9x = 0
-3 + -2x = 5 + 0
-3 + -2x = 5
Add '3' to each side of the equation.
-3 + 3 + -2x = 5 + 3
Combine like terms: -3 + 3 = 0
0 + -2x = 5 + 3
-2x = 5 + 3
Combine like terms: 5 + 3 = 8
-2x = 8
Divide each side by '-2'.
x = -4
Simplifying
x = -4
Solve for X please.
Answer:
x = -4
Step-by-step explanation:
12 + 8 + 2 = 22
So x will be negative
12 - 4 = 8
-4 + 8 = 4
2
8 + 4 + 2 = 14
Answer:
x= -4
Step-by-step explanation:
Essentially all that one needs to do is add up all the given values,
because each part, each segment of the line is a specific value
When added up, they create the whole line.
JI = 12+x
IH= x+8
HG = 2
JG = 14
so add up all the segments
JI + IH + HG = JG
12 +x + x + 8 + 2 = 14
simplify, and solve with inverse operations,
2x + 22 = 14
2x = -8
x = -2
check by substituting back into the problem
JI = 12 +x
12 - 4
=8
IH = x +8
-4 +8
=4
HG =2
JI + IH + HG = JG
8 + 4 + 2 = 14
A computer generates 90 integers from 1 to 5 at random. The results are recorded in the table.
What is the experimental probability of the computer generating a 1?
10%
20%
30%
40%
Outcome Number of times
outcome occurred
1 36
2 11
3 13
4 12
5 18
Answer:
40%
Step-by-step explanation:
36/90 integers are 1, so the experimental probability is ...
p(1) = 36/90 = 0.40 = 40%
Using it's concept, it is found that there is a 0.4 = 40% experimental probability of the computer generating a 1.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
For an experimental probability, these numbers of outcomes are taken from previous trials. In this problem, there have been 90 trials, and 36 resulted in a 1 being generated, hence:
p = 36/90 = 0.4.
0.4 = 40% experimental probability of the computer generating a 1.

Answer:
When a point is reflected across the y-axis, the y-coordinate(s) remain the same. But the x-coordinate(s) is transformed into opposite signs.
Answer:
the x coordinate
Step-by-step explanation:
When flipping over the y-axis, the x-coordinate's sign changes.

Given the original statement "If a number is negative, the additive inverse is positive,” which are true? Select three options. If p = a number is negative and q = the additive inverse is positive, the original statement is p → q. If p = a number is negative and q = the additive inverse is positive, the inverse of the original statement is ~p → ~q. If p = a number is negative and q = the additive inverse is positive, the converse of the original statement is ~q → ~p. If q = a number is negative and p = the additive inverse is positive, the contrapositive of the original statement is ~p → ~q. If q = a number is negative and p = the additive inverse is positive, the converse of the original statement is q → p.
Answer:
A. If p = a number is negative and q = the additive inverse is positive, the original statement is p → q.
B. If p = a number is negative and q = the additive inverse is positive, the inverse of the original statement is ~p → ~q.
D. If q = a number is negative and p = the additive inverse is positive, the contrapositive of the original statement is ~p → ~q.

The company plans to sell the video game console at a loss in order to increase its sale. It will make up for the loss from profits made from the sales of Games for the system. The company will lose $50 for each console it sells and earn a profit of $15 for each game sold for the system. Write an equation that can be used to determine T the total amount the company will earn from a customer who buys a consul and G games
Answer: [tex]T= 15 G - 50[/tex]
Step-by-step explanation:
As per given,
Total earning = (profit per game) x (Number of games) -(loss in consul)
Let T be the total amount the company will earn from a customer who buys a consul and G games.
Since, loss in consul = $50
profit per game = $15
Then required equation will be :
[tex]T= 15 G - 50[/tex] , it determines T the total amount the company will earn from a customer who buys a consul and G games.

Answer:
y=27.75
x=13.5
Step-by-step explanation:
(5x-17)+(3x-11)=180 (supplementary angle rule)
8x-28=180
8x=180+28
x=108/8
x=13.5
(3x-11)+90+(2y+5)=180 (supplementary angle rule)
29.5+90+2y+5=180 (replace x by 13.5)
2y=55.5
y=55.5/2
y=27.75
Amy is six years older than her brother Leo. Leo is seven years old. If n stands for Amy's age, which of these sentences could be used to find her age?
Answer:
n = 6+x
Step-by-step explanation:
Given that:
Amy is 6 years old than her brother Leo
Let consider the age of Leo to be x since we are not yet told how old is Leo
Then Amy is 6+x
Now, we know that Leo is seven years old,
i.e x = 7
If n stands for Amy's age,
Then, the algebraic expression showing how old is Amy's age can be expressed as n = 6+x
Amy's age (n) = 6+7
Amy's age (n) = 13
To solve any word problem, we need to define our conditions into system of the equations. Thus, Amy's age is 13 years.
Amy is six years older than her brother Leo.
Leo's age is seven years.
It is given in the question that Amy's age stands for 'n'.
Thus, according to the given conditions from the question.
The expression that defines the age of Amy is given below.
[tex]\rm{Amy's\;Age}=7+\rm{Leo's\;Age}\\n=7+6\\n=13[/tex]
Thus, Amy's age is 13 years.

Two angles are complementary if their sum is 90°. If the measure of the first angle is x°, and
the measure of the second angle is (3x - 2)°, find the measure of each angle.
Answer:
The first angle is 23°, the second angle is 67°Step-by-step explanation:
x° - measure of first angle
(3x-2)° - measure of second angle
Their sum is 90° so
x + 3x - 2 = 90
+2 +2
4x = 92
÷4 ÷4
x = 23
3x-2 = 3•23 - 2 = 69 - 2 = 67
Checking: 23+67 = 90

what are the midpoint between this two points
(-1,-5) and (-5,9)
Hey there! I'm happy to help!
To find the x value of the midpoint, you add the x values and divide by 2.
-1-5=-6
-6/2=-3
For the y value, you add the y values and divide by 2.
-5+9=4
4/2=2
Therefore, the midpoint is (-3,2).
