Answer:
Step-by-step explanation:let x be number of T-shirts and y be no of pants.
Total=70
I.e. x + y = 70 ..........1
Cost of one shirt=12$
Cost of one pant=$30
Total cost=12x +12y=1200$........2
1 +2
X+ y=70
12x+30y=1200
I.e. 12x + 12 y = 840
-(12x +30y)= -1200
.............................................
-18y = - 360
Y = 20
Therefore
No of shirts = x = 70 - y = 70-20=50$
No of pants =y=20$
Hope it is clear

Step-by-step explanation:
Answer:
12/1
Step-by-step explanation:
So before we can decide which graph it is, we have to find the zeros (x-intercepts) of this graph. We can do this by setting y to 0.
Firstly, factor out 3x on the right side of the equation: 
Next, use the zero product property to solve y = 0:


So we know that the zeros of this equation are (4,0) and (0,0). Looking at the four graphs, the only graph that has a line crossing those 2 points is the first graph. Therefore, the graph of this equation is the first graph.
D because it is more simpler than just using a graph
