Answer:

<span>y=−24</span>

Explanation:

<span><span>18</span><span>(5y+64)</span>=<span>14</span><span>(2y+20)</span></span>

multiply both sides by 8:

<span>5y+64=2<span>(2y+20)</span></span>

multiply out brackets:

<span>5y+64=4y+40</span>

subtract 4y from both sides:

<span>y+64=40</span>

subtract 64:

<span>y=40−64=−24</span>

<span>y=−<span>24
</span></span>

HELP !!!!!!!!!!!!!!!!

Fantom [35]

Answer:

∠2 = 51°

Step-by-step explanation:

The sum of supplementary angles = 180°

Equate the sum of the angles to 180 and solve for a

11a + 19 + 6a - 9 = 180

17a + 10 = 180 ( subtract 10 from both sides )

17a = 170 ( divide both sides by 17 )

a = 10

Hence

∠2 = (6 × 10) - 9 = 60 - 9 = 51°
