(d) 12 2/3
Answer:
I think it's B
Step-by-step explanation: I hope that helps
Answer:
(a) -8
Step-by-step explanation:
[tex] \frac{2}{3} \times ( - 7) + \frac{2}{3} \times ( - 5)[/tex]
[tex] - \frac{2}{3} \times 7 + \frac{2}{3} \times ( - 5)[/tex]
[tex] - \frac{14}{3} + \frac{2}{3} \times ( - 5)[/tex]
[tex] \frac{ - 14}{3} - \frac{2}{3} \times 5[/tex]
[tex] - \frac{14}{3} - \frac{10}{3} [/tex]

helppp me find x plz
Answer:
x = 5
Step-by-step explanation:
The ≅ sign means that both triangles are congruent, also meaning they're exactly the same. So with this in mind, the equations naturally equal each other:
3x + 3 = 5x - 7
Subtract 5x from both sides
-2x + 3 = -7
Subtract -3 from both sides
-2x = -10
divide by -2 to both sides
x = 5

which algebraic representation of a transformation on a coordinate grid does NOT preserve congruence?
A. ( x, y) -> ( x + 6, y + 6)
B. (x, y) -> (-x, y)
C. (x, y) -> (6x, 6y)
D. (x, y) -> (-y, x)
Answer:
the awnser is a
Step-by-step explanation:
The algebraic representation of the transformation that would not preserve congruence would be:
A). ( x, y) -> ( x + 6, y + 6)
"Algebraic Representation"A coordinated grid is characterized as the point or the grid comprised due to the intersection produced by two lines of the real number.
In this intersection, one line is defined as horizontal and the other line is vertical.
The representation [tex]( x, y) -> ( x + 6, y + 6)[/tex] fails to conserve the congruence.
Thus, option A is the correct answer.

Six less than five times a number is three more than twice the number.
Translate the verbal phrase into a mathematics
Answer:
5x - 6 -3= 2x
Step-by-step explanation:
Answer:
5x-6=2x+3
Step-by-step explanation:
six less than - so you subtract six from five time a number
five times a number - number is unknown so you use the variable "x"
is - equals
three more than - so you add three to two times the number
two times the number - the same number so it's represented with the same variable

The value of y is directly proportional to the value of x. If y = 45 when x = 180, what is the value of y when x = 90?
Answer:
22.5
Step-by-step explanation:
Because
180÷2=90
so that would mean
45÷2=22.5
Answer:
22.5
Step-by-step explanation:
X=180 and Y=45
180/4=45
so we know that by dividing X by 4 we get Y
in that case...
90 / 4 = 22.5

Simply the following square roots. Leave
the answer in a radical format.
V250
Answer: Here we answer "What is the square root of 250 (√250) in simplest radical form?" The square root of 250 in its simplest form means to get the number 250 inside the radical √ as low as possible.
Here is how to do that! First, we write the square root of 250 like this:
√250
The largest perfect square of the factors of 250 is 25. We can therefore convert √250 like this:
√25 × 10
Next, we separate the numbers inside the √ as such:
√25 × √10
√25 is a perfect square that equals 5. We can therefore put 5 outside the radical and get the final answer to the square root of 250 in simplest radical form as follows:
5√10

Step-by-step explanation:
Using the rule of radicals
[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]
Given
[tex]\sqrt{250}[/tex]
= [tex]\sqrt{25(10)}[/tex]

Please Help!!! And please dont answer with anything random I really need help!!!
okay, let's see if I can do this without my calculator
using the Bernoulli Trial equation (I think that's what it's called)
nCr x (p)^r x (q)^n-r
now 5C4 is 5 (Thanks Pascal's triangle)
p is 1/3
q is 2/3
r is 4
n is 5
(1/3)^4 is 1/81
(2/3)^5-4 is just 2/3
5 x 1/81 x 2/3 = 5 x 2/243 = 10/243
This was in my head so check for mistakes
