Answer:
5x+2y=13
Step-by-step explanation:
3x+3y=8
2x-y=5
5x+2y=13
Answer:
B
Step-by-step explanation:
They all follow a sequence such as always add 4 or take 6 away some of them multiply so it is B because it does not follow the sequence
Answer:
a: b: c= 2: 9 :4
Step-by-step explanation:
Since b is the common variable in both fractions, ensure that the value of b in both fractions are the same. Here, the value of b in both fractions are 9. Thus, we can find their relationship with one another in terms of ratio by combining the two fractions together.
a: b: c= 2: 9: 4
This ratio is already in it's simplest form.
It's hard to tell what the independent variable is here. Since time is often plotted on the horizontal axis, that's what has been done here.
