Answer:
210 high schoolers as ratio becomes 90:210
Step-by-step explanation:
we can see that 3:7 can be multiplied if 3 x 3 = 9 then 7 x 3 =21 we just add the zero and find a 90:210 ratio
2. 4(0) - 20(0) < 6
(5/2 (0)) >/= 5(0) - 10 ; it is a solution
3. 2.5 + 5(-1.5) > -10
2.5 - (-1.5) </= 4 ; it is also a solution
x y
( 0 , 0 )
(2.5, -1.5)
Plug it in, plug it in
3|–3x + 9| = –18
divide both sides by 3
|–3x + 9| = –6
