If x + x = 9, then x =
Answer: x = 4.5
Step-by-step explanation: First, do x + x, since they are like terms. That equals 2x. The equation is now 2x = 9. Divide both sides by 2. x = 4.5.
x + x = 9
2x = 9
÷2 ÷2
---------------------
x = 4.5
x + x = 9
4.5 + 4.5 = 9

Answer:
Step-by-step explanation:
Gabriela has solved incorrectly. 5 should distributed to 9x & (-8) and 4 should be distributed between x & 2
5(9x - 8) = 4*(x + 2)
5*9x - 5*8 = 4*x + 4*2
45x - 40 = 4x + 8
Subtract 4x from both sides
45x - 4x - 40 = 8
41x - 40 = 8
Add 40 to both sides
41x = 8 + 40
41x = 48
x = 48/41

what is the probability of picking the most expensive car from a range of 6 new cars
The solution is: 16.67% is the probability of picking the most expensive car from a range of 6 new cars.
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
Here, we have,
given that,
the most expensive car from a range of 6 new cars.
so, total sample space = 6
the number of favorable outcome = 1
so, probability = 1/6
Now, the word “expensive” was used to confuse you but simply put, the probability of getting “the most expensive car” is 1/6.
It is 1/6 because there is nothing that heightens its chances of being picked over the other cars,
hence the probability of any car will be equal to that of the “most expensive car”.
And for a percentage:
(1/6) x (100) = 16.67%
Hence, The solution is: 16.67% is the probability of picking the most expensive car from a range of 6 new cars.

Answer:
The value of "h" = 32 unit
Step-by-step explanation:
Given:
In given parallelogram
Height for base 36 = 24
Height for base 27 = h
Find:
The value of "h"
Computation:
Area of parallelogram = Base x Height
For base 36
Area of parallelogram = 36 x 24
Area of parallelogram = 864 unit²
For base 27
Area of parallelogram = 27 x h
864 = 27 x h
The value of "h" = 864 / 27
The value of "h" = 32 unit

What is the y-intercept of the line perpendicular to the line y = x + 1 that includes the point (4, 1)?
Answer:
The intercept of the line perpendicular to the line [tex]y = x + 1[/tex] is 5.
Step-by-step explanation:
The line [tex]y = x + 1[/tex] has a slope 1. By Analytic Geometry, the slope of the line perpendicular to the original line is determine by the following formula:
[tex]m_{\perp} = -\frac{1}{m}[/tex] (1)
Where:
[tex]m[/tex] - Slope of the original line.
[tex]m_{\perp}[/tex] - Slope of the line perpendicular to the original line.
If we know that [tex]m = 1[/tex], then the new slope is:
[tex]m_{\perp} = -\frac{1}{1}[/tex]
[tex]m_{\perp} = -1[/tex]
A line is defined by the following expression:
[tex]y = m\cdot x + b[/tex] (2)
Where:
[tex]x[/tex] - Independent variable.
[tex]y[/tex] - Dependent variable.
[tex]m[/tex] - Slope.
[tex]b[/tex] - Intercept.
If we know that [tex](x,y) = (4,1)[/tex] and [tex]m = -1[/tex], then the intercept of the line perpendicular to the original line:
[tex]b = y - m\cdot x[/tex]
[tex]b = 1+4[/tex]
[tex]b = 5[/tex]
The intercept of the line perpendicular to the line [tex]y = x + 1[/tex] is 5.

There were 24 1/4 crates of tomatoes in the barn but 7 3/5 crates of tomatoes were rotten and had to be thrown out. Joe sold 8 1/3 crates and canned 7 5/6 crates of tomatoes. How many crates of tomatoes were left?
Answer:
29/60 of the crates are left behind.
Step-by-step explanation:
Total number of crates = 24 1/4= 97/4
Rotten tomatoes crates = 7 3/5= 38/5
Joe sold crates = 8 1/3= 25/8
Canned crates of tomatoes =7 5/6= 47/6
Therefore
24 1/4 - 7 3/5 - 8 1/3 - 7 5/6
= 97/4-38/5-25/3-47/6
= (97*5-38*4)/20 - (25*2+47)/6
= 485-152/20 - 97/6
= 333/20-97/6
= 333*3-97*10/60
=999-970/60
=29/60
29/60 of the crates are left behind.

normally distributed with a mean of 78 and a standard deviation of 7. The top 15% of all scores have
been designated A’s. Your score is 89. Did you earn an A? Explain.
Answer:
YesStep-by-step explanation:
z-score representing 85% is 1.04 (from table)
Let x be the score representing the lower limit of 85%.
Use the formula to find z-scores:
z = (x - μ)/σWe have:
z = 1.04, μ = 78, σ = 7Substitute the values and solve for x:
1.04 = (x - 78)/7x - 78 = 7.28x = 85.28The lower limit of the top 15% is 85.28.
Since your score is greater than 85.28 you earned an A

What is the area of the square?
Answer:
C. 25 ft²
Step-by-step explanation:
the length of side = 20/4 = 5 ft
so the area of the square = 5² = 25 ft²
Answer:
C: 25 ft2
Step-by-step explanation:
Perimeter is the factor of all the side lengths added together. If 4 equal sides added together equals 20, what times 4 equals 20? 5 times 4 equals 20. Which means the side length is 5. Area is side length x side length, so 5 x 5=25 so the answer is C hope this helps!
