Answer:
A because they 35 needs to stay with 100 and x needs to stay with 275 and 100 and 275 have to be on the same part of the ratio
Step-by-step explanation:
1/2 - 3/8 = 4/8 - 3/8 = 1/8
you have to find a common denominator before you can subtract. in this case it is 8
I think that it would be 3x + 1.
1 and 2 are supplementary angles. The sum of their measures is equal to 180 degrees.
I hope this helps. =)
Answer:

Step-by-step explanation:
1) if to re-write the given equation into slope-interception form, then:

the slope of the given line is 5/2;
2) according to the rule of perpendicular, the required slope should be:
s*(5/2)=-1;
3) if to solve this equation (s*5/2=-1), then s=-2/5 or -0.4.
