8. Find GH, E 3-4 HY - H 2 3x - 4 G SI F 9x - 59 D

Ostrovityanka [42]

Answer:

GH= 47

Step-by-step explanation:

$2(3x - 4) = 9x - 59$

$6x - 8 = 9x - 59$

$6x - 9x = - 59 + 9$

$\cfrac{ - 3x}{ - 3} = \cfrac{ - 51}{ - 3}$

$x = 17$

$gh = 3(17) - 4$

$51 - 4$

$= 47$

Determine if y varies directly with x. Give the constant of variation, when appropriate. (picture below)

maxonik [38]

Based on the given variation, y does not vary directly with x and the constant of variation are 8, 3.2 and 1.25 respectively.

<h3>Variation</h3>

y = k × x

where,

k = constant of proportionality

y = -40

x = -5

y = k × x

-40 = k × -5

-40 = -5k

k = -40/-5

k = 8

when,

y = 8 and x = 2.5

y = k × x

8 = k × 2.5

8 = 2.5k

k = 8/2.5

k = 3.2

when,

y = 5 and x = 4

y = k × x

5 = k × 4

5 = 4k

k = 5/4

k = 1.25

1 and 5/6 + 2 and 2/11

lions [1.4K]

$1 \frac{5}{6} +2 \frac{2}{11} =\frac{(1\times6)+5}{6} +\frac{(2\times 11)+2}{11} =\frac{11}{6}+\frac{24}{11} \\\\=\frac{11\times 11}{6\times 11} +\frac{24\times6}{11\times6} =\frac{121}{66} +\frac{144}{66}=\frac{121+144}{66} =\frac{265}{66}\\\\=\boxed{\bf{4\frac{1}{66}}}$
