Step-by-step explanation:
The question asking for the linear equation Suzie manipulated. The answer should be equal to the starting equation. So, we just need to manipulate the option to y= mx + c format.
1. y + 7x = 23
y= -7x +23 (false)
2. . –7x + y = 23
y= 7x + 23 (true)
3. 2y – 14x = 46
2y= 14x+ 46
y= 7x +23 (true)
4. y – 7x = –23
y= 7x - 23 (false)
5. 7x – y = –23
-y= -7x -23
y= 7x + 23 (true)
Answer:Number Example Natural number are those number which we can count.It denoted by N
Step-by-step explanation:
The correct question is
<span>A student ate 3/20 of all candies and another 1.2 lb. Another student ate 3/5 of the candies and the remaining 0.3 lb. Altogether, what weight of candies did they eat?</span>
let
x-------> total <span>weight of candies
we know that
x=(3/20)*x+1.2+(3/5)*x+0.3
</span>x=(3/20)*x+(3/5)*x+1.5----> multiply by 20----> 20x=3x+12x+30
20x=15x+30
20x-15x=30
5x=30
x=6 lb
the answer is
6 lb
