Answer:
9:5
Step-by-step explanation:
I think it's 9:5 sorry if I'm wrong.
EC bisects so m<BEC = m<CED
11x - 12 + 2(4x + 1) = 180
11x - 12 + 8x + 2 = 180
19x - 10 = 180
19x = 190
x = 10
m<AEB= 11x - 12 = 11(10) - 12 = 98
m<CED = 4x+1 = 4(10) + 1 = 41
m<BEC = m<CED = 41
so
m<AEC = m<AEB + m<BEC
m<AEC = 98 + 41
m<AEC =139
answer
m<AEC =139
So you just plug in the X value of the number that d represents for example if I plug in 2 for d
7(2)^2+10=38
Answer:
He paid $9 twelve times
12× 2= 24 days
Step-by-step explanation:
1st day = $16.60
3rd day=$ 9 (i.e for every 2days afterwards)
5th day=$ 9
Yuri pays : 124.60
124.60-16.60
= $108.00
After paying the first day he paid 108.00
108.00÷ 9 = 12
He paid $9 twelve times
12× 2= 24 days
