Step-by-step explanation:
5×6'3n=20
30'3n=20
3n=20-30
3n/3= -10/3
n= -3
Answer:
c
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
= , substitute values
= ( cross- multiply )
10YZ = 230 ( divide both sides by 10 )
YZ = 23 → c
Answer:
i= -6
Step-by-step explanation:
-5i-15=15
if we use inverse operation here, it would be -5i=30, so i= -6
