<span>The answer is 2 person. The relation for 2 persons is as following: 2 minutes = 2 gingerbread men. If those 2 persons want to make 400 gingerbread men, they will need x minutes. So: 2 minutes : 2 gingerbread men = x : 400 gingerbread men. x = 2 minutes * 400 gingerbread men : 2 gingerbread men = 400 minutes. In other words, 2 persons will make 400 gingerbread men in 400 minutes.</span>
The total number of books is the sum of the chapter books and picture books, 11+7 =18
Thus 18 is the total number of books
If she gave away 1/3 of the books, 6 books were given away as 1/3 of 18 is 6
=> Ella gave 6 books to her cousin
Answer:
2) x=-4 y=4 4) x=0 y=-4
Step-by-step explanation:
<em>2)</em> Step: Substitute x+8 for y in y=−4x−12:
y=−4x−12
x+8=−4x−12
x+8+4x=−4x−12+4x (Add 4x to both sides)
5x+8=−12
5x+8+−8=−12+−8 (Add -8 to both sides)
5x=−20
5x
/5 = −20
/5 (Divide both sides by 5)
x=−4
Step: Substitute −4 for x in y=x+8:
y=x+8
y=−4+8
y=4 (Simplify both sides of the equation)
Answer:
x=−4 and y=4
<em>4) </em>Step: Substitute 3x−4 for y in y=x−4:
y=x−4
3x−4=x−4
3x−4+−x=x−4+−x (Add -x to both sides)
2x−4=−4
2x−4+4=−4+4 (Add 4 to both sides)
2x=0
2x/2 = 0
/2 (Divide both sides by 2)
x=0
Step: Substitute 0 for x in y=3x−4:
y=3x−4
y=(3)(0)−4
y=−4 (Simplify both sides of the equation)
Answer:
x=0 and y=−4
