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:
<u>Group the Variable's</u>:
2 x - 5 + 7 y - 3 = 9 x - 1 - y -8
2x -9x + 7y +y = -1 -8 +5 + 3
-7x + 8y = -1
<u><em>From this find x and y</em></u>
<u>For X</u>
-7x + 8y = -1
-7x = -1 -8y
7x = 8y + 1
x = (8y +1)/7
<u>For Y</u>
-7x + 8y = -1
8y = -1 +7x
y = (7x -1)/8
<span>12x^2 − 96x + 189 = 0
3 (2x-7) </span>(2x-9)<span>= 0
</span>2x - 7 = 0; x = 7/2 = 3.5<span>
2x - 9 =0; x = 9/2 = 4.5
answer
x = 3.5 and x =4 .5
