Step-by-step explanation:
6
145-68.50 = 76.50
76.20/12.75 = no of t-shirts she can buy
ans= 6
c=9
Step-by-step explanation
8-5c=-37
-37-8= -5c
-45= -5c
-45/-5=c
u=2s
one solution.. your answer is correct
discriminate = 900 - (4*9*25) = 0
thus only one solution
a) Finding value of y:
8y+4+4y+7=107
12y+11=107
12y =107-11
12y =96
y = 96/12
y = 8
b) RS= 8y+4
= 8(8)+4
= 64+4
= 68
ST= 4y+7
= 4(8)+7
= 32+7
= 39
