- (x + 2)2 + (y - 9)2 = 1
telo118 [61]

Answer:

x+y=-5.75

Step-by-step explanation:

Ⓗⓘ ⓣⓗⓔⓡⓔ

Well, you would simply need to use the distributive property!

-(2)x-(2)2+(2)y-(2)9=1

-2x-4+2y-18=1

Then you need to add/subtract so the similar numbers are together.

-2x+2y-22=1

-2x+2y=23

x+2y=-11.5

x+y=-5.75

35% of the students at charles drew middle school are 6th graders if there are 84 sixth graders what is the total number of stud
Juliette [100K]

Answer: The total number of student in the school  = 240.

Step-by-step explanation:

Let x be the total number of students in the school.

Given: 35% of the students at Charles drew middle school are 6th graders.

i.e. Number of sixth graders = 35% of x = 0.35x   [35% = 0.35]

Since there are 84 sixth graders in the school,

So  0.35x=84

Divide both sides by 0.35, we get

x=\dfrac{84}{0.35}=\dfrac{84\times100}{35}=240

Hence, the total number of student in the school  = 240.
