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
Answer:
yes that is right
Step-by-step explanation:
19/25 or 76/100 so it would be 76%
Answer:
x=22
Step-by-step explanation:
Rule states diagonals = same so 6x-36 = 96 in which x=22 cause 6(22)=132
132-36 = 96
Question 1
Let the scale factor be k.
Then, we have the mapping

This implies that:

We equate any corresponding component find the value of the scale factor k.
6k=2


Hence the scale factor is 
Question 2:
The midpoint of any two points can be calculated using the formula;

We want to find the midpoint of (-8, 5) and (2, -2).


The midpoint is:
