Answer:
x=16
(5x + 27)° =5(16)+27=80+27=107
(5x – 7)º= 5(16)-7=80-7=73
Step-by-step explanation
supplementary angle=180
(5x + 27)° + (5x – 7)º=180
5x+27+5x-7=180
10x+20=180
10x=180-20
10x=160
x=160/10
x=16
(5x + 27)° =5(16)+27=80+27=107
(5x – 7)º= 5(16)-7=80-7=73
107+73=180
Answer:
7

Answer:
$2315.25
Step-by-step explanation:
Given data
Principal= £2000
Time= 3 years
Rate= 5%
The compound interest expression is
A= P(1+r)^t
substitute
A= 2000(1+0.05)^3
A= 2000(1.05)^3
A= 2000*1.157625
A= 2315.25
Hence the Amount is $2315.25
