Answer:
[ 4 2 ] x [ -2 5 7 -1 ] = [- 10,836]
Step-by-step explanation:
Here, the given expression is:
[ 4 2 ] x [ -2 5 7 -1 ]
Now solving : [ -2 5 7 -1 ] , we get
[ -2 5 7 -1 ] = [-258]
Now simplifying
[-258] x [ 4 2 ] = - 10,836
⇒ [ 4 2 ] x [ -2 5 7 -1 ] = [- 10,836]
Hence the solution is: [- 10,836]
Answer:
x=5 miles
Step-by-step explanation:
first you have to get his constant speed or his rate
rate = time / distance
so in this case 27/3 which equals 9,
1 mile = 9 minutes
then, you would set up your equation
9 minutes = 1 mile
45 minutes = x miles
cross multiply , 45 * 1= 45 , then divide by 9
x = 5 miles
Yes.
8/20 = 6/15 = 4/10 = 2/5
