Answer:
n=12
Step-by-step explanation:
7n-18 =5n+6
+18 to both sides
7n=5n+24
-5n from both sides
2n=24
divide by 2
n=12
<span>{[(16 ÷ 4) × (2 × 6)] ÷ 6} + 4 =
</span><span>{[(4) × (12)] ÷ 6} + 4 =
</span>{[4 × 12] ÷ 6} + 4 =
{[48] ÷ 6} + 4 =
{48 ÷ 6} + 4 =
{8} + 4 =
8 + 4 =
12
So if they are similar then just try to figure out which two sides correspond to each other from the first and then the second triangle.
See how in the above example I did 20 and 5 not 20 and 14 or 20 and 3.5 because they do not correspond with one another.
Then figure out, is x on the mama or baby shape and either multiply the number received from all proportions or divide.
Multiply : small to big ( # missing on the bigger one )
Divide : big to small ( # missing on the smaller one)
