Answer:
I think x = 5.25
Step-by-step explanation:
Since they are corresponding angles, they should be congruent.
90 = 16x - 6
84 = 16x
x = 5.25
Answer:

Step-by-step explanation:

Since they're equidistant (equal distances), we can set them equal to one another and solve for x:

Adding 5 to both sides:

Subtracting 2x from both sides:

Dividing both sides by 3:

Therefore:

Answer:
4
Step-by-step explanation:
Let x = the number of years
In x years, Mai's mother's age will be: 28 + x
and Mai's age will be: 12 + x
Then, 28 + x = 2(12 + x)
Distribute the 2 28 + x = 24 + 2x
Subtract 24 from each side 4 + x = 2x
Subtract x from each side x = 4
In four years, Mai's mother will be twice Mai's age.
<em>Check:
</em>
28 + 4 = 2(12 + 4)
32 = 2 × 16
32 = 32
11/20 is already reduced you cannot simplify this fraction
