Answer:
<u>52 cm</u>
Step-by-step explanation:
1st piece (from bottom) = 67 cm
15th piece = 32 cm
a = 67
a₁₅ = a + 14d = 32
14d = 32 - 67
d = -35/14
d =-5/2
d = -2.5
a₇ = a + 6d
= 67 + 6(-2.5)
= 67 - 15
= <u>52 cm</u>
Answer:
Wakaranai
Step-by-step explanation:
2(4z−2) = 44
Simplify both sides of the equation.
Distribute:
(2)(4z)+(2)(−2) = 44
8z + −4 = 44
8z − 4 = 44
Add 4 to both sides.
8z − 4 + 4 = 44 + 4
8z = 48
Divide both sides by 8
8z/8 48/8
z = 6
