Answer:
3.
Step-by-step explanation:
This is an arithmetic sequence with common difference d = 0.5 and first term a1 = -015.
10th term = a1 + (10 - 1)d
= -1.5 + 9*0.5
= 4.5 - 1.5
= 3.
Answer:D
407(1+0.26)
=407*1.26
=512.82
WXY = XYW ( = 41 ) ⇒ XYW is a isosceles triangle
⇒ XW = YW
⇒ 54 = 6x + 6
⇒ 6( x + 1 ) = 54
⇒ x + 1 = 9
⇒ x = 8
ok done. Thank to me :>
let's firstly convert the mixed fractions to improper fractions and then divide.
