Answer:
5
Step-by-step explanation:
If two is subtracted from a number: let's give the number a name and call it X . And this difference is tripled: so we get 3(X−2) . The result is 4 more than the number, so
3(X−2)=4+X .
We want to know X so we need to get it to one side of the equation. That's done by repeatedly doing the same operation on both sides of the equation. First get rid of the parentheses:
3X−6=4+X.
Now subtract X and add 6 :
2X=10
Divide by 2:
X=5
Answer:
x = 1
Step-by-step explanation:
The mathematical equation is 1-3x=2-4x

In basketball the number of points you score is given by 3x+2y+1z where x is three pointers y is two pointers and z is free throws
Answer:
Answer
4.0/5
29
Based on the given, x = 333 three-pointers, y = 5 two-pointers, and z = 6 free throws, and the total number of points scored is:
3x + 2y + z = 3(333) + 2(5) + (6) = 999 + 10 + 6 = 1015
*If the number of three-pointers is actually 3, then the actual total score is:
3(3) + 2(5) + (6) = 9 + 10 + 6 = 25.

A 6 foot tall person casts a shadow 8ft long at the same time a building can cast a shadow 48 feet long how tall is the building
Answer:
36 feet
Step-by-step explanation:
We can use the tall person's shadow as a ratio to help us witht his problem.
The ratio would be 6:8
Once we know how tall the shadow cast is, we can divide that by 8 to be within the same ratio.
48 / 8 = 6
Then once we do that we multiply that by 6
6 x 6 = 36
And there we go, that's the answer.

Need help with this geometry work show work hard for me pls answer fast due now
Answer:
see explanation
Step-by-step explanation:
(1)
The sum of the 3 angles in a triangle = 180° , thus
a + b + c = 180
(2)
adjacent angles are supplementary, thus
b + d = 180
(3)
From (1) and (2)
b + d = a + b + c ( subtract b from both sides )
d = a + c
Five digit serial numbers for a product are to be made using letters and/or numbers, e.G. JGR29. The serial number could have all letters, all numbers or a mix of both. Repetition of characters is NOT allowed. How many such serial numbers can be made?
Answer:
1,404,000 serial numbers can be made
Step-by-step explanation:
For the five digit serial numbers, since all letters and all numbers could be used, then we can use 26 letters (A,B,C,...Z) and 10 numbers (0,1,2,...9).
Now, say the letters and numbers are to occupy the labeled spaces below
_ _ _ _ _
1 2 3 4 5
(NOTE: Spaces 1,2,3 are to be occupied by any of the 26 letter while spaces 4 and 5 are to be occupied by any of the 10 numbers)
For space 1, there are 26 possibilities
For space 2, there will be (26 -1 ) 25 possibilities (since repetition of characters is NOT allowed)
For space 3, there will be (26-2) 24 possibilities (since repetition of characters is NOT allowed)
For space 4, we have 10 possibilities
and for space 5, we (10-1) 9 possibilities (since repetition of characters is NOT allowed)
Therefore, the number of serial numbers that can be made is
26 × 25 × 24 × 10 × 9 = 1404000
Hence, 1,404,000 serial numbers can be made
OR
Using permutation, nPr = n!/(n-r)!
For the letters,
n is the total number; n = 26
and r is the number of available spaces, r = 3
For the numbers,
n = 10
r = 2
Then, we get
26P3 × 10P2
26!/(26-3)! × 10!/(10-2)!
26!/23! × 10!/8!
15600 × 90 = 1404000

for AC: 4 + 4 = 8
8 is the AC of the red triangle
4 is the AC of the blue triangle
to get from 8 to 4, we divide by 2 or multiply by 1/2 (they mean the same thing)
10 is the CB of the red triangle
5 is the CB of the blue triangle
to get from 10 to 5, we divide by 2 or multiply by 1/2
The perimeter of a square field is 900 m. Find its area.
Answer:

9m+4n
Step-by-step explanation:
this equation, according to me, can be written in two other ways
(3m+5n) - (-6m+n) or 3m+5n-n+6m (this is the same equation without the parenthesis and it is distributed
3m+5n-n+6m= 9m+4n

does anyone know what l 17=5x-6 is??
Answer:
4.600
Step-by-step explanation:
Just add 6 to both sides
Cancel out/Ignore the 6
Add 6+17=23
Then do 23/5 to get x
x=4.6
Answer: x=4.6
Step-by-step explanation: First you get 5x to the other side so you subtract it so it becomes -5x+17=-6 Then you subtract 17 from both sides so you get -5x=-23 Then you divide -5 on both sides so you get x=4.6
Given the slope of 2 and the point (3.5), write the equation for the line.
Answer:
y = 2x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2 , thus
y = 2x + c ← is the partial equation
To find c substitute (3, 5) into the partial equation
5 = 6 + c ⇒ c = 5 - 6 = - 1
y = 2x - 1 ← equation of line

Suppose that a consumer's preferences are well behaved in that properties 4-1 to 4-4 are satisfied and the initial equilibrium consumption bundle consists of 10 units of X and 25 units of Y. If PY increases such that the new equilibrium consumption bundle is 15 units of X and 10 units of Y, then goods X and Y are:
Answer:
Normal goods
Step-by-step explanation:
Initial consumption bundle: X = 10 units and Y = 25 units
After the price of Y rises
So,
The new Consumption bundle is
X = 15, Y = 10
Hence, Good X and Y are normal goods .
As the price of good Y increases, the consumption of good Y decreases from 25 to 15 units as the actual revenue decreases, so the consumption decreases
Although the price of good X stays the same but is now comparatively lower, demand increases mean that consumption increases as real revenue increases.
This indicates that the sales impact is positive, implying that good X and Y are ordinary items.
