Answer:
A. x<31 and x > -5
Step-by-step explanation:
| X-13 |< 18
Seperate into 2 equations, one positive and one negative, remembering to flip the inequality for the negative
x-13 < 18 and x -13 > -18
Add 13 to each side
x-13+13 < 18+13 and x-13+13> -18+13
x < 31 and x>-5
<em>Greetings from Brasil...</em>
According to the statement, one figure is scaled in relation to another, so we can apply similarity to polygons.....
So
BIG/small = BIG/small
or
small/BIG = small/BIG
12.5/10 = X/16
OR
10/12.5 = 16/X
12.5/10 = X/16
10X = 12.5 · 16
X = 200/10
<h3>X = 20</h3>
35 cm
using the formula a=1/2(b)(h), we can plug in 14 for b and 5 for h. This gives us 70, and when we multiply by 1/2 it leaves 35 cm.
Answer:
y=29
Step-by-step explanation:
Since the angles are across a vertex from one another, they are congruent and equal. You can also see this by reflecting or folding it in half through the vertex. They will be the same. This means we can write the following equation and solve using inverse operations:
4y-8=79+y
4y-y-8=79+y-y
3y-8=79
3y-8+8=79+8
3y=87
y=29
