What is the value of x?<br> pls help im so confused

Makovka662 [10]

In the proportional theory,

28 units is the total measurement that includes 8 units.

So, 10 + 3x - 5 is the total measurement that includes 10 units proportionally.

This means,

28 = 10 + 3x - 5

Now solve for x,

28 = 10 + 3x - 5

28 - 10 = 3x - 5

18 + 5 = 3x

23 = 3x

23 / 3 = x

So x = 23/3 or 7.6666....

Need help with my work pleasem

Galina-37 [17]

Let me start with the second screenshot :-
To find the scale factor you have to enlarge/ dilate A to get B you have a given side so assume that all sides are dilated to the same extent
: . $1 \frac{1}{2} / \frac{3}{4} = 2
$

Thus one can say m would be
$\frac{1}{2} * 2 = 1$

And N would be
$\frac{5}{6} * 2 = \frac{10}{6}$
