Lets represent a tin of beans as
and a jar of jam as
.
Therefore
3b+4j=2080 and 5b=2000.
Now we can say that b=400.
Substitute b in 3b+4j=2080 for 400.
3*400+4j=2080
Simplify
1200+4j=2080
4j=880
j=220.
Therefore
1 tin of beans is 400 grams and 1 jar of jam is 220 grams.
Answer:
11
Step-by-step explanation:
The answer to that one would be D.
The answer is y>2x+2 and y<x+1; (-3, 1)
It would be A. 9-2n. I Hope this helped.
we have
----> inequality 1
The solution of the inequality 1 is the shaded area below the solid red line
The solution is the region D and region C
-----> inequality 2
The solution of the inequality 2 is the shaded area above the solid blue line
The solution is the region B and region C
The solution of the system is the common area
so
The solution is the region C
see the attached figure
therefore
the answer is the option C
Region C
