What is 10a - 5b if a = 25 and b = 3
Answer:
[tex]\boxed{235}[/tex]
Step-by-step explanation:
Hey there!
Well given that,
a = 25
b = 3
10(25) - 5(3)
250 - 15
= 235
Hope this helps :)
Hi there! Hopefully this helps!
-------------------------------------------------------------------------------------------------------
Answer: 235.~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~First we need to substitute the value of the variable into the expression:
10a - 5b = 10(25) - 5(3).
Now we Multiply 10 and 25 to get 250.
250 − 5 × 3 = 235
Multiply 5 and 3 to get 15.
250 − 15 = 235
Subtract 15 from 250 to get, you guessed it, 235!given the function f(x)=5(x+4)-6 solve fot the inverse function when x=19
Answer:
I got 109
Step-by-step explanation:
f(x)=5(x+4)-6 x=19
f(19)=5(19+4)-6
*Add 19 + 4 because it is in ()* f(19)=5(23)-6
*Multiply because it is the first in the order of operations* f(19)=115-6
*Now just subtract* f(19)= 109
what are scaled copies? and how to use them?
Answer:
A scale copy of a figure is a figure that is geometrically similar to the original figure. This means that the scale copy and the original figure have the same shape but possibly different sizes. First you have to look at one of the sides of the scaled copy. If they are divisible by the numbers in the original shape, then try and see if the others sides of the scaled copy are scaled by the same factor. If they are, then they are a scaled copy.
The ideal gas equation says that the product of the pressure, P, and the volume of a gas, V, is equal to the number of miles of the gas,n, times the gas constant, R, times the temperature of gas,T.
PV=nRT
which of the following equations is equivalent to the ideal gas equation?
Algebra 1
Answer:
T=PV/nR
Step-by-step explanation:
Use the division property of equality to solve the ideal gas equation for T. Divide both sides of the equation by nR, then simplify.
PV=nPT
PV/RT=nRT/nR
PV/nR=T
Therefore, the equation below is equivalent to the ideal gas equation.
T= PV/nR

Effects of Shifting, Adding and Removing Data
Pamela works at the zoo. She was looking at some data showing the weight of their 4 giraffes. The mean of weight of the giraffes was 1,800 pounds and the median weight was 2,000 pounds. Then gets a baby giraffe that weighs 500 pounds. How would the addition of the baby giraffe affect the mean and median?
Chose one:
• Both the mean and median increased.
• Both the mean and median decreased.
• The mean increased, but the median decreased.
• The median increased, but the mean decreased.
Answer: Both the mean and median decreased.
Step-by-step explanation:
The addition of the 500 lb baby elephant will have a huge impact on the mean, since you'll be finding the average (adding all numbers then dividing). So the only logical answer would be the chosen. The median will most likely either decrease or stay the same, but since staying the same isn't an option for the median, it's most likely going to be decrease.

If a dog moves 3 meters due East and then 4 meters due North, what will be the dispalcement of the dog?
Answer:
The displacement of the dog which is the shortest distance between the two points is 5 meters 53.13° North of East
Step-by-step explanation:
The given parameters are;
The dog's displacement due East = 3 meters
The dog's displacement due North = 4 meters
The displacement, D motion of the dog can be written in vector form as follows;
D = 3i + 4j
The magnitude of the displacement is given as follows;
[tex]\left | D\right | = \sqrt{(3 \ meters)^2 + (4 \ meters)^2} = \sqrt{25 \ meters^2} =5 \ meters[/tex]
The displacement is the shortest distance between two points
The direction is given tan⁻¹(4/3) = 53.13° North of East
The displacement of the dog which is the shortest distance between the two points = 5 meters 53.13° North of East.

Who knows the answer!?
Quickly.
Answer:
x = 95
Step-by-step explanation:
The sum of the angles of a quadrilateral is 360
x +115+46+ 104 = 360
Combine like terms
x+265=360
Subtract 265 from each side
x +265-265 = 360-265
x = 95
4x + 3y = 26 3x - 2y=11
Answer:
x = 5
Step-by-step explanation:
2 (4x + 3y = 26)
3 (3x - 2y = 11)
8x + 6y = 52
9x - 6y = 33 [the 6y and -6y cancel out]
17x = 85 [divide both sides by 17 to find x]
x = 5
Step-by-step explanation:
Hey, there!!
Given,
4x + 3y = 26........(i)
3x -2y = 11............(ii)
Multiplying equation (i) by 2 and equation (ii) by 3 we get,
8x - 6y = 52
9x + 6y = 33
17x = 85 { cancelling 6y and -6y}.
[tex]x = \frac{85}{17} [/tex]
Therefore, x= 5.
Now, putting the value of x is equation (i)
4x + 3y = 26
4×5 + 3y = 26
20 + 3y = 26
3y = 26 -20
[tex]y = \frac{6}{3} [/tex]
Therefore, y = 2.

co efficient of x^2 in (2-x) (5-3x) (1-7x)
Answer:
+ 80
Step-by-step explanation:
Given
(2 - x)(5 - 3x)(1 - 7x) ← expand the first two factors using FOIL
= (10 - 11x + 3x²)(1 - 7x)
Each term in the second factor is multiplied by each term in the first factor
= 10(1 - 7x) - 11x(1 - 7x) + 3x²(1 - 7x) ← distribute the 3 parenthesis
= 10 - 70x - 11x + 77x² + 3x² - 21x³ ← collect like terms
= - 21x³ + 80x² - 81x + 10
The coefficient of the x² term is + 80

Complete question :
Vanessa and Zack are playing a game where the player with the lower score wins. At the end of the game, Vanessa has a score of -3 5/8 and Zack has a score of -3 2/3. Which statement explains who won?
Vanessa won. If you compare the decimal equivalents of their scores, -3.625 < -3.666.
Vanessa won. If you compare the decimal equivalents of their scores, -3.666 < -3.625.
Zack won. If you compare the decimal equivalents of their scores, -3.625 < -3.666.
Zack won. If you compare the decimal equivalents of their scores, -3.666 < -3.625
Answer: Zack won. If you compare the decimal equivalents of their scores, -3.666 < -3.625
Step-by-step explanation:
Given that :
Player with the lowest score wins ;
Vanessa's score = - 3 5/8
Zack's score = - 3 2/3
Converting to decimal:
Vanessa :
-3 5/8 = - 29 /8 = - 3.625
Zack:
-3 2/3 = - 11/3 = - 3.666
Comparing the scores :
From the negaryce side of a number line :
-3.666 comes before - 3.625, hence, - 3.666 is lower or lesser than - 3.625
-3.666 < - 3.625, hence Zack won
Answer:
D. Comparing the decimal equivalents of their scores shows that Zack won because -3.6 (line over 6) if less than -3.625.
