Ответ:
-10y + 11.4
I hope this helps you out
Ответ:
-10y+11.4
Step-by-step explanation:
you combine -2y with -8y to get negative -10y. Then you combine 3 and 8.4 to get 11. Variables usually come first in equations, I don't think it matters, but you might want to put them first anyway.
Ответ:
x=4
Step-by-step explanation:
so there are two triangles in that shape and they are similar to each other because their angles are equal and the ratio of their sides it 1:2
so the ratio of the side 5x & 40 is 1:2
5x/40=1/2
10x=40
x=4
