Answer from: kyle65

1. distribute

step 1: 3 3

× X = X

5 5

3 5 3 Ima convert this into a decimal

× - = - > negative .375

5 8 8

2. write the problem now

3 1 7

X - 0.375 = - X +

5 12 8

3. I would convert them into decimals and solve

0.6x - 0.375 = 0.08 - x + 0.875

+x +x

1.6x - 0.375 = 0.08 + 0.876

1.6x - 0.375 = 0.956

+0.375 +0.375

1.6x = 1.331

1.6 1.6

x = 0.831875

rounded up : 0.83

Answer from: jason8093

Combine like terms
1/12+7/8=2/24+21/24=23/24
3/5(x-5/8)=23/24-x
one easey way is to get rid of nasty fractions

find lcd of denoms
5 and 24
hmm
24*5=120

times both sides by 120

72(x-5/8)=115-120x
distribute
72x-45=115-120x
add 120x to both sides
192x-45=115
add 45 to both sides
192x=160
divide both sides by 192
x=5/6

x=5/6

Maybe the answer is 20mm. all i really did was just multiply, which is obvious.
Find the surface area of the cylinder.give your answer in terms of pi.

Answer from: Quest

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

= $\sqrt{(9-6)^{2} +(12-6)^{2} } \\=\sqrt(45)=3\sqrt(5)$

side j'k'=distance between j' and k'

= $\sqrt{(3-2)^{2} +(2-4)^{2} } \\=sqrt(5)$

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
