You were on the correct path in the beginning, so it was 100%. You then had a fork of two ways, and taking one randomly leaves you with a 50% chance of being on the right track. The second fork cuts your chances in half again, so 25%. There is a 25% chance you are still on the correct path.

S is in between T and U. ST = x + 4 and SU = 2x. TU = 16. Find the value of x.
solniwko [45]
You know the total length ST and SU, so to find x you would write an equation. This would be: x+4+2x=16 Combine like terms: 3x+4=16 Subtract four from both sides: 3x=12 Divide both sides by three: x=4

Kristen spent $131 on shirts. Fancy shirts cost $28 and plain shirts cost $15. If she bought a total of 7 then how many of each
Sloan [31]
<span>1 x + 1 y = 7 .............1
Total value
15 x + 28 y = 131 .............2
Eliminate y
multiply (1)by -28
Multiply (2) by 1
-28 x -28 y = -196
15 x + 28 y = 131
Add the two equations

-13 x = -65
/ -13
x = 5
plug value of x in (1)
1 x + 1 y = 7
5 + y = 7
y = 7 -5
y = 2
y = 2
x= 5 plain shirts
y= 2 fancy shirts </span>

Can someone please help me and explain I’ll mark brainliest

Part (a)

<h3>Answer:   x = -8</h3>

------------------

Work Shown:

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

2x-2 = 3x+6 .... distribute

2x = 3x+6+2 .... adding 2 to both sides

2x = 3x+8

2x-3x = 8 .... subtracting 3x from both sides

-x = 8

x = -8 ..... multiply both sides by -1

===========================================================

Part (b)

<h3>Answer:  x = 5/11</h3>

------------------

Work Shown:

-4(2x-2) = 3(x+1)

-8x+8 = 3x+3 ..... distribute

-8x = 3x+3-8 .... subtract 8 from both sides

-8x = 3x-5

-8x-3x = -5 ... subtract 3x from both sides

-11x = -5

x = -5/(-11) .... divide both sides by -11

x = 5/11

In decimal form, this is approximately equal to 5/11 = 0.4545
