Answer:
13.5 minutes
Step-by-step explanation:
Cross multiply
3 × 576 = 128x
3 × 576 = 1,728
1,728 = 128x
1,728 ÷ 128 = x
13.5 = x
Answer:
D. 1/44
Step-by-step explanation:
divide both sides by the # in front of X - in this case its 6. you should get x= 3/22 ÷ 6 and get your answer there by plugging in the calculator. or on paper-
do 3/22 × 1/6 which is also reduced to --> 1/22 × 1/2 and that is 1/44 but you should be able to jist plug 3/22÷ 6 in if you take middle/highschool math anyways
21 is 25% of 84
21 • 4 = 84
You can check this answer by take 25% of 84.
84 • 0.25 = 21
What is the rule in this sequence (0,21) (1,18) (2,15) (3,12) (4,9) (5,6) (6,3) (7,0) (8,-3) (9,-6) (10,-9)

Answer:
x + 1 & y - 3
Step-by-step explanation:
Because... the x-values are going up by 1 digit each and the y-values are going down by 3 digits each.
You divide 3 on both sides then you equation is the square root of -4x-4 =4 and you square the number on both sides because u need to do the same things on both sides and you get -4x-4=16 subtract by 4 on boyh sides to get -4x=20 and divide by -4 on both aises to get x=-5
I hope this helped i know this explanation is a bit wonky
