Alex swims at an average speed of 45 m/min. How far does he<br> swim in 1 min 24 sec?<br> m
denpristay [2]

Answer:

63 m

Step-by-step explanation:

We know the rate in 45 m / min

We need to change the time to min

1 min 24 sec

We know that 1 min = 60 sec  so 24 seconds is 24/60 ths of a minute

1 min 24/60 min

1 2/5 min

Changing to decimal form

1.4 minutes

Now we multiply by the rate to get the distance

d = r *t

d = 45 m/ min * 1.4 min

d= 63 m

Answer:

x=7

Step-by-step explanation:

Step 1: Subtract 4x from both sides.

x+30−4x=4x+9−4x

−3x+30=9

Step 2: Subtract 30 from both sides.

−3x+30−30=9−30

−3x=−21

Step 3: Divide both sides by -3.

−3x

−3

=

−21

Ava is in charge of bringing bottled water to a party that has 42 guests.
olya-2409 [2.1K]

Answer:

a - about 3 packs cause you have to round up

b - $50.76

Step-by-step explanation:

First you divide 42 and 18.

42/18=2.33

You have to round up cause you can't have half of a pack, you can't just buy half of a pack.

So, it is rounded to 3 packs.

Next you have to multiply the number of packs and the cost of each pack of water bottles.

16.92*3=$50.76

a - you have to buy 3 packs

b - the total cost is $50.76
