10≤n<100
So the number of two digit numbers is 99-10+1=90
The only combinations that sum to 5 are 14, 23, 32, 41, 50 so
P(sum=5)=5/90
P(sum=5)=1/18
Answer:
$6.8
Step-by-step explanation:
Let x be the amount of money in Molly's amount
according to question,
4x-25=2.20
4x=2.20+25
4x=27.20
x=27.20/4
x=6.8
So,the amount of money in Molly's amont is $6.8
As we see, two triangles are congruent triangles
So 36/42 = 6/x
<=> 6/42 = 1/x
<=> 6x = 42
<=> x = 7cm
I’m not really sure if it correct, g(1)=0 or g(1)=1??
