Product property is the answer
<em>multiply both sides by 5 </em> 3(15k+10)=5(12k-9)
<em>get rid of the brackets</em> 45k+30=60k-45
<em>take away 45k to both sides</em> 30=15k-45
<em>plus 45 to both sides</em> 75=15k
<em>divide both by 15</em> k=5
12*3= 36
12 and 3 could be factors of 36.
I hope this helped you! <3
Step-by-step explanation:
3. (c) complementary since the sum of the angles is 90°
4. 5x + 95 = 180 ---> 5x = 85 or x = 17 ans (d)
5. 68 + x + 90 = 180
x + 158 = 180
x = 22
ans. (b)
