Hey all! This is the another one, pls show the working......
zhannawk [14.2K]

Answer:

Hi again, I'm here to answer!

The correct answers:

10. x = -7 2/3

11. x = 2

12. x = 3

Step-by-step explanation:

(x + 3)/2 = (x - 4)/5

(5x + 15)/10 = (2x - 8)/10

3x/10 = -23/10

x = -23/3

x = -7 2/3

(2x - 1)/3 = x/2

(4x - 2)/6 = 3x/6

x/6 = 2/6

x = 2

(3x + 1)/5 = 2x/3

(9x + 3)/15 = 10x/15

-x/15 = -3/15

x = 3

Hope this helped!

Please help me. I'm stupid.
Gwar [14]

Answer:

\displaystyle 36\:units

Step-by-step explanation:

Split up this Isosceles, Right Triangle into two congruent smaller right triangles. The reflexive side [the line that splits them apart] is 6 units, and both legs are 8 units, leaving the hypotenuses to AUTOMATICALLY be 10 units, according to the Pythagorean Theorem:

\displaystyle a^2 + b^2 = c^2 \\ \\ 6^2 + 8^2 = 10^2 \\ \\ 36 + 64 = 100 \\ \\ 100 = 100

With this Pythagorean Triple, we know that our dimensions are correct. Now, to find the perimeter, just add up all the sides EXCEPT for the divider:

\displaystyle 2[10] + 2[8] = 20 + 16 = 36

I am joyous to assist you anytime.

If jane give £2 pounds to charlotte they will have equal amount of money. instead
OverLord2011 [107]
Jane has 20 pounds and Charlotte has 16 pounds

Let j = amount Jane has and c = amount Charlotte has

j - 2 = c + 2 if Jane gives Charlotte 2 pounds
j + 4 = 2(c - 4) if Charlotte gives Jane 4 pounds
j + 4 = 2c - 8
Subtract equation 1 from equation 3
6 = c - 10
c = 16
j = c + 4 = 20
