Answer:

JK=18.8

Step-by-step explanation:

so we are given that ΔGHI ~ ΔJKL

GI~JL (because corresponding parts of similar triangles are similar)

so GI/JL=ratio of similitude=7/33

GH~JK (corresponding parts of similar triangles are similar)

and GH/JK=ratio of similitude

so:

GH/JK=GI/JL

subsitute known values

4/JK=7/33

cross multiply

7JK=132

divide

JK=132/7

simplify and round

JK≈18.8

hope this helps!

Half x + 10 equals quarter x + 54

IgorLugansk [536]

½(x+10) = ¼(x+54)
Solving it

x/2 + 5 = x/4 + 13.5
x/2 - x/4 = 13.5 - 5
x/4 = 8.5
x = 8.5 × 4 = 34

The denominator of a fraction is two more than the numerator. If both numerator and denominator are decreased by six, the simpli

Answer:

$\dfrac{40}{42}$

Step-by-step explanation:

Let the numerator of the fraction=x

Since the denominator of a fraction is two more than the numerator.

Denominator=x+2

The fraction is therefore:

$\dfrac{x}{x+2}$

If both numerator and denominator are decreased by six, the fraction becomes:

$\dfrac{x-6}{x+2-6}$

The simplified result is $\dfrac{17}{18}$

Therefore:

$\dfrac{x-6}{x+2-6}=\dfrac{17}{18}\\$Next, we solve for x\\Cross multiply\\18(x-6)=17(x+2-6)\\18(x-6)=17(x-4)\\Expand the bracket\\18x-108=17x-68\\Collect like terms\\18x-17x=-68+108\\x=40$

Substituting x=40 into the initial fraction

$\dfrac{x}{x+2}=\dfrac{40}{40+2}=\dfrac{40}{42}$

Therefore, the original fraction is $\dfrac{40}{42}$
