d) 60

Step-by-step explanation:

so two numbers a+b=90 and also a-b=30

Lets assume a is the larger number. So we can plug and chug for time purposes I will explain why 60 is the answer. so 60-30=30 so b would be 30 and a would be 60. Also a+b or 60+30= 90 and that is the case the smaller number is 30 and the larger number is 60

first one is a: renaming a fraction. second one is c: de-c

step-by-step explanation:
