5) The 8th Graders and 7th Graders are in a race to see who can collect the most cans for the food drive. The 8th Grade has 25 cans and is collecting at
a rate of 10 cans per day. The 7th Grade currently has 50 cans and is
collecting 5 cans per day. If the competition lasts 20 days, who will win and
how many cans will they have?
Work
Variable (and what it
stands for)
Answer in complete sentence

8th grade will win with 225 cans

X= 25 + (20 * 10)

7th grade will lose with 150

X= 50 + (20 * 5)

X to represent the number of cans at the end of the 20 days

Step-by-step explanation:

8th grade will have 225 can by the end of the competition while,

7th grade will have 150 cans

8th grade explantation:

20 times 10 is 200

20 days and 10 cans per day is 200 cans

200 + 25= 225

200 cans in 20 days and the 25 cans at the start is 225

7th grade explantation:

20 times 5 is 100

20 days and 5 cans per day is 100 cans

100 + 50 = 150

100 cans in 20 days and the 50 cans at the start is 150

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
