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>
Answer:
Step-by-step explanation:
You can multiply the numerator and denominator by 2
(4.5/5.5)(2/2)=9/11
So I think that number 6 is just dividing by 3 and the second one doesn't like divide so number 7 is no and number 6 is yes
Answer:
O=30° or O=29°
Step By Step Explanation:
∠α =arcsin( a/c )
= arcsin(4/8)
= arcsin(0.5)
= 0.5 rad = 30° = 29°
I Hope This Helps. I Gave you 2 answers just in case 1 is Wrong. And I Hope you Understand This Calculation, I Used Different Variables and the arcsin thing is something my teacher told my class to use, and I Have no Idea what it means because my teacher never explained what it meant, Sadly.
