Translate (in terms of x) then solve the algebraic equation: The sum of a number and 3 is subtracted from 10 the result is 5.
Answer:
The answer is 2
Step-by-step explanation:
Let the number be x
10 - (3 + x) = 5
10 - 3 -x = 5
7 - x = 5
x = 7-5
x = 2
Question 13, pls help & tell how to do the problem thank u
Answer:
(-4,-10) and (5,-3)
Step-by-step explanation:
To be honest, this kind of question allows for any coordinates as long as they have the slope of 9/7.
I know the slope equation is (y2-y1)/(x2-x1) = m (where m is slope)
(y2-y1)/(x2-x1) = 9/7
From this equation, find any two numbers that have a difference of 9 to the y-coordinates.
I'll go with 5 and -4 (y-coordinates)
And two integers that have a difference of 7 for the x-coordinates.
I go with -3 and -10 (x- coordinates)
So the points I got are,
(5-(-4))/((-3)-(-10)) = 9/7
5-(-4) is equal to 5+4 (2 minus signs are equal to 1 plus sign), which is 9.
(-3)-(-10) is equal to -3+10 (2 minus signs are equal to 1 plus sign), which is 7.
The two points are (-4,-10) and (5,-3)
Notice if we were to subtract 5 from -4, we would also have to subtract -3 from -10.
-4-5= -9 and -10- -3 = -10+3 = -7
-9/-7 is the same as 9/7.
Basically, (-4,-10) and (5,-3) are different coordinates and you can only switch them as coordinate 1 or 2 but not the points.
Sorry, took a while, hope I was able to help! Good Luck.

Answer:
(8x - 9)˚ = 63˚
and
(3x)˚ = 27˚
Step-by-step explanation:
heeyyyyy remember me?
Complementary angles are angles that equal 90˚, so we can create an equation:
(8x - 9) + 3x = 90
Remove the paranthesis
8x - 9 + 3x = 90
Add 9 to both sides
8x + 3x = 99
Simplify
11x = 99
divide both sides by 11
x = 9
So if we plug in x for 9 we get:
8x - 9
8(9) - 9
72 - 9
63
3x
3(9)
27
So
(8x - 9)˚ = 63˚
and
(3x)˚ = 27˚

Explain how to compare decimals use the numbers 6.75 and 6.732 to help you explain this process
Answer:
6.75>6.732
Step-by-step explanation:
We are given that
6.75 and 6.732
We have to compare two given decimal numbers.
First we convert like decimal number
In 6.75 there are two digits after decimal point.
In 6.732 , there are three digits after decimal point
Therefore, we put zero in 6.75 to convert like decimal number
Now, we get
6.750
Unit place of both decimal numbers are same and tenth place of both decimal number are same.
Now, hundredth place of 6.750 is 5 and hundredth place of 6.732 is 3
5 >3
Therefore, 6.750 is greater than 6.732
6.75>6.732

Step-by-step explanation:
An engineer designed a valve that will regulate water pressure on an automobile engine. The engineer designed the valve such that it would produce a mean pressure of 5.9 pounds/square inch. It is believed that the valve performs above the specifications. The valve was tested on 160 engines and the mean pressure was 6.0 pounds/square inch. Assume the variance is known to be 0.36. A level of significance of 0.05 will be used. Determine the decision rule.
Answer:
Calculated value Z = 2.1097 > 1.96 at 0.05 level of significance
There is a difference between the means
Step-by-step explanation:
Step(i):-
Given that mean of the Population = 5.9pounds/square inch
Given mean of the sample = 6.0pounds/square inch
Given that variance of the Population = 0.36
The standard deviation of the Population = √0.36 =0.6
critical value (Z₀.₀₅)= 1.96
Step(ii):-
Null Hypothesis:H₀: x⁻ = μ
Alternative Hypothesis:H₁: x⁻ ≠ μ
Test statistic
[tex]Z = \frac{x^{-}-mean }{\frac{S.D}{\sqrt{n} } }[/tex]
[tex]Z = \frac{6.0-5.9 }{\frac{0.6}{\sqrt{160} } }[/tex]
Z = 2.1097
Final answer:-
Calculated value Z = 2.1097 > 1.96 at 0.05 level of significance
The null hypothesis is rejected
There is a difference between the means

a. 180 b. 18 c. 54 d. 30
*Check the attachment for the pie chart
Answer:
C. 54
Step-by-step explanation:
Total number of students under survey = 300
Percentage of students who chose fish as their favorite = 18%
Number of students who chose fish as their favorite pet = [tex] \frac{18}{100} * 300 [/tex]
[tex] = 18 * 3 [/tex]
[tex] = 54 [/tex]
54 students chose fish as their favorite pet.

at 6:00 a.m., the temperature is 58°. At 2:00 p.m., temperature is 76°. Find the rate of change in degrees per hour during this time.
Answer:
The rate of change is of 2.25 degrees per hour.
Step-by-step explanation:
The rate of change in degrees per hour is given by by the change in temperature divided by the change in time(by number of hours).
In this question:
From 6 am to 2 pm, there are 12 - 6 + 2 - 0 = 6 + 2 = 8 hours
The change in temperature was of 76 - 58 = 18º
Rate of change:
18º/8 = 2.25º
The rate of change is of 2.25 degrees per hour.
why do some metals react with only steam?
Answer:
Metals which react with steam form the solid metal oxide and hydrogen gas.
In general, the more reactive the metal, the more rapid the reaction. Aluminium is unusual, because it is a reactive metal that does not react with water. Its surface forms a protective layer of aluminium oxide that keeps water away from the metal below.
The apparatus used to react a metal with steam and collect the gas produced is shown below.
Answer:
This is because some metals like aluminium, zinc, iron do not react with hot/cold water ; they react only with steam to form a metal oxide and hydrogen.
