Thanks for using brainly!B. 0.3 would be the answer.
To find z, you have to divide -3 and 10, which you would get an odd number. That will be your answer for z :)
2:3:5
2x+3x+5x=180
10x=180
x=18
2x=36
3x=54
5x=90
Answer:
r=7
Step-by-step explanation:
5r-7=2r+14
add sevento both sides
5r=2r+21
Subtract 2r from both sides.
3r=21
divide both sides by 3
r=7
