X=3 . ok well ur gonna do reverse mathematics so start by subtracting 2 from 17 (bc the oppistite of addition is subtraction) an then rewrite the equation. 5x=15 and then divide 15 by 5 and it equals 3 and then do it all over again meaning put the equation as it was but with the value. 5x3+2=17 and it all makes sense. im so sorry i answered so late i just got this question recommended to me.
Answer:
70 minutes
Step-by-step explanation:
3 1/2 ÷1/4= 14 ×5= 70
so you first make 3 1/2 to an improper fraction, then you find the greatest common denominator between 7/2 and 1/4 which is 4, so you multiple 7/2 by 2 and get 14/4 and divide that by 1/4 and get 14minutes now multiply that by 5 laps and receive 70 minutes.
Answer: -6
Step-by-step explanation:
-3 - 3 = -6
because when you have a minus number and subtract another number it is like its going up like:
-1 - 3= -4
but if you look on a number line it a clearly going down.
Hope this helped u.
Set up a proportion
54 60
— = —
x 100
(100)(54)= 60(x)
5400=60x
x= 5400/60
x=90
