Given 4x+10=5(x-4)
Prove x=30
Answer:
Step-by-step explanation:
First, we expand the brackets, so we have
4x + 10 = 5x - 20, then we collect like terms to have
5x - 4x = 10 + 20, then we sum them up
x = 30

Step-by-step explanation:
The perimeter of a rectangle is 14 inches. The equation that represents the perimeter of the rectangle is 2l+2w=14, where l represents the length of the rectangle and w represents the width of the rectangle. Which value is possible for the length of the rectangle?
6 inches
7 inches
8 inches
9 inches
Answer:
6 inches
Step-by-step explanation:
6 inches is the only feasible answer because if the length is 6 inches, you have 6 + 6 which equals 12. This leaves 2 more units for the perimeter so the width would be 1 unit. The other choices could not exist, because 7 x 2 is 14 (no units left for width, and the width of a rectangle cannot be 0), 8 x 2 is 16, and 9 x 2 is 18.

Answer:
y = 3x - 6
Step-by-step explanation:
What you do is you plug both points in for the equation 2 times and solve as a system of equations.
Equation of a line: y = mx + b
(x,y) = (3,3)
(x,y) = (6,12)
3 = 3m + b
12 = 6m + b
Subtract equations to get rid of b to solve for m.
12 - 3 = 6m - 3m + b - b
9 = 3m
m = 3
Plug m back into both equations get b.
3 = 3(3) + b
b = -6
12 = 6(3) + b
b = -6
y = 3x - 6
Answer:
[tex]\displaystyle y = 3x - 6[/tex]
Step-by-step explanation:
First, find the rate of change of the line:
[tex]\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{-3 + 12}{-3 + 6} = m \hookrightarrow \frac{9}{3} = m \\ \\ \boxed{3 = m}[/tex]
_______________________________________________
Now plug all the information into the Slope-Intercept Formula. It does not matter which ordered pair is chosen:
[tex]\displaystyle 12 = 3[6] + b \hookrightarrow 12 = 18 + b; -6 = b \\ \\ \boxed{\boxed{y = 3x - 6}} \\ \\ OR \\ \\ 3 = 3[3] + b \hookrightarrow 3 = 9 + b; -6 = b \\ \\ \boxed{\boxed{y = 3x - 6}}[/tex]

Step-by-step explanation:
a person buys a washing machine in the condition that he shall pay sum of INR 5880 at the cash down payment and the same sum at the end of the first year and two years. what is the total interest paid by him in this scheme, if the rate of interest is 5% compounded yearly?
Answer: $827
Step-by-step explanation:
Given that :
Cash down payment = 5880
Payment at end of first year = 5880
Payment at end of second year = 5880
Interest rate = 5% = 0.05 compounded yearly
Let purchase amount = y
Amount left after cash down = amount on which interest is paid = y - 5880
Interest at end of first year :
(y - 5880) * 0.05 = 0.05y - 294
Amount to pay plus interest :
Amount left after cash down payment - amount paid at end of first year + interest
y - 5880 - 5880 + 0.05y - 294
y - 12054 + 0.05y
= 1.05y - 12054
2nd year interest :
(1.05y - 12054) * 0.05
= 0.0525y - 602.7
Amount left + interest = 2nd year payment
(1.05y - 12054) + (0.0525y - 602.7) = 5880
1.1025y - 12656.7 = 5880
1.1025y = 5880 + 12656.7
1.1025y = 18536.7
y = 18536.7 / 1.1025
y = 16813.33
Hence,
Sales price of washing machine = 16813.33
Total amount paid = (5880 + 5880 + 5880) = 17640
Interest paid = $(17640 - 16813.33) = $826.67
= $827
The total interest paid by him in this scheme, if the rate of interest is 5% compounded yearly is INR 826.67
Given:
Down payment = INR 5880
Payment at end of first year = INR 5880 (same as down payment)
Payment at end of second year = INR 5880 (same as down payment)
Interest rate = 5%
= 5/100
= 0.05 compounded yearly
Amount of purchase = x
Amount remaining after down payment
= x - 5880
Interest at end of first year :
(x - 5880) * 0.05(5,880)
= 0.05x - 294
Amount to pay plus interest = Amount remaining after down payment - amount paid at end of first year + interest
= x - 5880 - 5880 + 0.05x - 294
= x - 12,054 + 0.05x
= 1.05x - 12,054
2nd year interest :
(1.05x - 12054) * 0.05
= 0.0525x - 602.7
Amount left + interest = 2nd year payment
(1.05x - 12054) + (0.0525x - 602.7) = 5880
1.1025x - 12656.7 = 5880
1.1025x = 5880 + 12656.7
1.1025x = 18536.7
divide both sides by 1.1025
x = 18536.7 / 1.1025
x = 16,813.33
Therefore, The cost of washing machine b is INR 16,813.33
Total amount paid = (5880 + 5880 + 5880) = INR 17,640
Amount of Interest paid = (17640 - 16813.33)
= INR 826.67

Answer:
d. x = 10 (the correct answer is marked)
Step-by-step explanation:
The Pythagorean theorem tells you the sum of the squares of the sides of a right triangle is the square of the hypotenuse.
x² +4² = (2√29)²
x² +16 = 116 . . . compute the squares
x² = 100 . . . . subtract 16
x = 10 . . . . take the square root
Answer:
d) [tex]\sf x=10[/tex]
Step-by-step explanation:
Pythagoras' Theorem: [tex]\sf a^2+b^2=c^2[/tex]
(where [tex]\sf a[/tex] and [tex]\sf b[/tex] are the legs, and [tex]\sf c[/tex] is the hypotenuse, of a right triangle)
Given:
[tex]\sf a=4[/tex][tex]\sf b=x[/tex][tex]\sf c=2\sqrt{29}[/tex]Substituting these values into the equation and solving for [tex]\sf x[/tex]:
[tex]\sf \implies 4^2+x^2=(2\sqrt{29})^2[/tex]
[tex]\sf \implies 16+x^2=116[/tex]
[tex]\sf \implies x^2=116-16[/tex]
[tex]\sf \implies x^2=100[/tex]
[tex]\sf \implies x=\pm \sqrt{100}[/tex]
[tex]\sf \implies x=\pm10[/tex]
Since distance is positive, [tex]\sf x=10[/tex] only
Therefore, the answer is d) [tex]\sf x=10[/tex].
explain what the standard deviation is for a set of data.
Answer:
The Standard Deviation is a measure of how spread out numbers are. You might like to read this simpler page on Standard Deviation first. But here we explain the formulas. The symbol for Standard Deviation is σ (the Greek letter sigma)
Answer:
Shows the variation in data(average of all means of the data)
Step-by-step explanation:
Ok,so, if for example, data is grouped close together, then the standard deviation will be small, if the data is more spread out then the deviation will be larger. How to tell?
Well, it all depends on the distance away from the mean. The center is usally where the mean is. How far from the mean is your data?
How to calculate?
-There are multiple equations you can use depending on your data.
If you are analyzing data which represents a larger set, use sample standard deviation, if you collect data from every member of the set, then use population standard deviation.
First, calculate the mean(average) of each set of data.
Then subtract the deviance(subtract mean from each number -/+)
Square each deviation
add up all squared deviations
Divide the number by one less than the number of items in the data. (If it was 5 it would be 4.)
Then calculate the square root of the resting value.

Both angles added together = 180 degrees. They both have a straight line as their base.
So let <ABC = x
Then <CBD = 3x Add the two angles
x + 3x = 180 Combine
4x = 180 Divide by 4
4x/4 = 180/4
x = 45
So 3x = 3*45 = 135
