Answer:
15/25
Step-by-step explanation:
So to answer this. lets find the value of 9/15
9/15
=
0.6
Now we know the value of the fraction is 0.6. Now we need to find th4e value of x that makes 15/x=0.6
To find the answer for this, just divide 15 by 0.6:
15/0.6
=
25
<u>So now we know that 15/25 is equal to 9/15</u>
Hope this helps! ;)
Step-by-step explanation:
I guess we only need to add 2 hours and 38 minutes to the depart times to get arrival, and deduct 2 hours and 38 minutes from arrival to get departure.
a) 05 00 -> 07 38
b) 07 20 -> 09 58
c) 08 40 -> 11 18
d) 10 58 -> 13 36
e) 15 45 -> 18 23
f) 18 22 -> 21 00
g) 18 39 -> 21 17
h) 20 47 -> 23 25
Dear HopellennibH, you need to FOIL. It is an algorithm to use when multiplying two binomials. Here are the steps. The "F" means to multiply the first two terms which gives you x squared. The "O" means to multiply the first term by the outer term, which gives you -8x. The "I" means to multiply the inner terms, which -9 times x which gives you -9x. The "L" means to multiply the last terms, which are -9 times -8, which gives you 72. Write the terms in standard form and you have x squared -17x +72.
Opening up the bracket
-5x-4x+24= -3
-9x= -3 - 24
-9x = -27
divide both sides by -9
x= 3
