Answer:
71
Step-by-step explanation:
vertical sides are congruent
x+30=101
x=71
The numbers are 90 and 60. this is because with a ratio 3:2 and multiplying each # in our ratio by 30 gets us the numbers 90:60......
and adding 90 + 60 will get us 150
The answer has to be the lowest negative number
-x + 1/2 = x + 4 1/2
+x +x
1/2 = 2x + 4 1/2
-4 1/2 - 4 1/2
-4 = 2x
x = -2
Well range is the difference between the highest and lowest numbers so 20-7 is 13
