Answer:
c) 2x+1
Step-by-step explanation:
Let's x be number of Nick's goals.
Emma has scored 1 more than twice the number of Nicks.
1 more is +1, of twices the number is 2x.
so 2x+1=15
2x+1=15
twice the number of Nick's goals is 2x
one more is +1
together that's 2x+1
and it should be Emma's number of goals, 15
3/10
mom = 35 when girl is born
girl = 0 when born
after 15 year
mom = 35 + 15 = 50
girl = 0 + 15 = 15
fraction = girl / mom = 15/50 = 3/10
140
