Answer:
4-10x
Step-by-step explanation:
24a+48=18a-36
24a-18a=-36-48
6a=-74
a=-74/6
a=-37/3
Answer:
6. 13.50/2= 6.25~ about 6 pens
7. 306/24= 12.75 about 13 bags
Step-by-step explanation:
If the figure is triangle then,
Let PR be x
So,
PQ+QR+PR= 180 (Sum of all the angles of the triangle)
Therefore,
6x+25+16-3x+x=180
4x+36=180
4x= 180/36
x= 144/4
X= 36
NOW,
PQ= 6x+25
= 6(36)+25
= 216+25 = 241= PQ.
QR = 16-3x
= 16-3(36)
= 16-108
= -92
PR = 36
hope it helps
