Answer:
8x + 16y = 39 and
40x + 8y = 42
Step-by-step explanation:
Let the length of the blue tiles is b inches and that of the white tiles is w inches.
So, given that a row of 8 blue tiles and 16 white tiles has a length of 39 inches and a row of 40 blue tiles and 8 white tiles has a length of 42 inches.
Therefore, we can write the system of linear equations that represents the relationship between the length if a blue tile and a white tile in inches as
8x + 16y = 39 and
40x + 8y = 42 (Answer)
First you would add 5 to both sides
X/8=3
Then multiply both sides by 8
X=24
Answer:
c=20 or SU = 20
Step-by-step explanation:
I'M HURRRRYYYINNNNNG DON'TT WORRY!!! :D
Use the Pythagorean theorem:
a²+b²=c²
Plug it in:
12²+16²=c²
144+256=400
c²=400
c=√400
c=20
There did i finish on time!!? XD
