Hello there!
12/15 and 8/10 don't have the same value.
Reason:
let's simplify both.
12/3 = 4
15/3 = 5
12/15 = 5/4
8/2 = 4
10/2 = 5
8/10 = 4/5
5/4 is greater than 4/5
5/4 > 4/5
Hope i helped!
Let me know if you need anything else!

Step-by-step explanation:
Remove the two triangles of 64cm² and 100cm²
In exponential form 720,080 is:
7 × 10^5
+ 2 × 10^4
+ 0 × 10^3
+ 0 × 10^2
+ 8 × 10^1
+ 0 × 10^0
Answer:
-3
Step-by-step explanation:
7(-3x-7y-56)
-21x-49y-392
-3(-7x+10y-1)
21x-30y+3
because the eq. multiplied by 7 is negative, the second eq mus be positive in order to eliminate the x variable. this is why we multiply by a (-). by multiplying the second eq by 3, both eq. will result in a coefficient of 21. one positive one negative allowing the x variable to be eliminated from the problem.
