Answer:
X=1
Step-by-step explanation:
In this question there are information's of immense importance and that can go a long way in helping to solve the given question. It is given that one brother eats 3/5 of the cereal and the other brother eats 3/10 of the cereal. The answer that needs to be found is that the amount of cereal the other brother eats more.
The amount of cereal eaten more by the other brother = (3/5) - (3/10)
= ( 6 - 3)/ 10
= 3/10
So the other brother does not eat more, but the first brother has eaten 3/10 more than the other brother.
We can replace the inequality with qual sign:
2x - y = 4
x + y = -1
We can combine both question
3x = 3
x = 1
Since we know x = 1, we can solve for y by plug in in either equation:
x + y = -1
1 + y =-1
y = -2
or
2x - y = 4
2(1) - y = 4
-y = 2
y = -2
So the solution of this system of equation is the coordinate (1, -2)
Answer:
D
Step-by-step explanation:
The range of a set of numbers is
range = largest number - smallest number , then
range = 25 - 6 = 19 → D
