2/5x+y=3
-2/5x -2/5x
y=-2/5x+3
Does y = to whole number or just like that? if it Whole number I will solve it tell me
The scale factor is:

So you divide the corresponding lengths and the ratio you get is the scale factor. Hope it helps!

Information is either qualitative or quantitative
Qualitative data is described with words
Quantitative data is described with numbers
Quantitative Information is expressed using numbers
Step-by-step explanation:
1)X represents the time he spent in cardio.
Y represents the time he spent in weighted.
2)If you could put the options on the second one it would be better.
3)4x+y=210
3x+2y=195
y=210-4x
3x+2(210-4x)=195
3x+420-8x=195
5x=420-195
5x=225
x=45
y=30
Total time of one cardi and weighted = 75min= 5/4 h.
4)2x+4y=
90+120=210 total time of week three.
