the ratio of girls to boys in the sixth grade is 5:3. If there are 400 sixth graders, how many boys are there?
PilotLPTM [1.2K]

Answer:

boys = 250

girls = 150

Step-by-step explanation:

5g = 3b       eq. 1

g + b = 400       eq. 2

g = girls

b = boys

From the eq. 2

g = 400 - b

Replacing this last eq. on eq. 1:

5(400-b) = 3b

5*400 + 5*-b = 3b

2000 - 5b = 3b

2000 = 3b + 5b

2000 = 8b

2000/8 = b

250 = b

From eq. 2

g + 250 = 400

g = 400 - 250

g = 150

Check:

from eq. 1

5*150 = 3*250  = 750

Plz help due tomorrow!!!!
Talja [164]

Answer:

E' = (-4, 3)  Answer C in your list of options

See attached image for the plot.

Step-by-step explanation:

Recall that a rotation in 180 degrees around the origin produces the following change in coordinates: (x, y) --> (-x, -y)

Therefore, since we read the coordinates of point E as: (-4, 3),

the new coordinates after the rotation will be: (4, -3) and the point will look like the red point in the attached image.
