Answer:
A. 16; 36
Step-by-step explanation:
If the triangles are equal
sides QS = side TV
3v+1 = 5v-9
subtract 3v from each side
3v+1 -3v = 5v-3v-9
1 =2v-9
add 9 to each side
1+9 = 2v-9+9
10 = 2v
divide by 2
10/2 =2v/2
5=v
QS = TV = 3v+1 = 3(5)+1 = 16
<r = <u
4n+4 = 5n-4
subtract 4n from each side
4n+4 -4n = 5n-4n -4
4 = n-4
add 4 to each side
4+4 =n-4+4
8 =n
<r = <u = 4n+4 = 4*8+4 = 36
She has used 630 min
1400*.45=630
.45 is equal to 45%
Answer:
9:12 and 12:16

There were 210 starlings, just multiply 42 by 5.
Answer:
8th term is 179.15904
Step-by-step explanation:
The sequence is geometric with a common ration = 6/5
r = 60/50 = 72/60 = 6/5
Use the formula

In your case a = 50, r = 6/5 and n = 8
