Answer:

D

Step-by-step explanation:

8 meters in 25 seconds

Seconds = S

Rewrite

8 = 25S

Divide both sides of the equation by 25

S = 0.32

Matt needs to swim 0.32 meters per second

D

Hope this helps :)

Answer:

Option D, 0.32 meters per second

Step-by-step explanation:

<u>Step 1:  Find the unit rate at which Matt needs to swim</u>

Make an equation to represent the scenario.

<em>25m = 8</em>

<u>Step 2:  Solve for m by dividing both sides by 25</u>

25m / 25 = 8 / 25

<em>m = 0.32</em>

<u>Step 3:  Check</u>

To check, you can multiply the number of second, 25, by the meters per second to see if you get the total meters, 8.

0.32 * 25

<em>8</em>

So, the answer is correct :)

<u><em>0.32 means that Matt needs to swim 0.32 meters per second to qualify as a state swimmer.</em></u>

Answer:  Option D, 0.32 meters per second

The nut shack sells cashews for $6.00 per pound and Brazil nuts for $5.00 per pound. How much of each type should be used to mak
Kay [80]

Answer:

Number of pounds of cashews = x = 14.96 pounds

Number of pounds of Brazil nuts = y = 19.04 pounds

Step-by-step explanation:

Let us represent:

Number of pounds of cashews = x

Number of pounds of Brazil nuts = y

The nut shack sells cashews for $6.00 per pound and Brazil nuts for $5.00 per pound. How much of each type should be used to make a 34 pound mixture that sells for $5.44 per pound

Our system of equations is given as:

x + y = 34...... Equation 1

x = 34 - y

6x + 5y = 34 × 5.44

6x + 5y = 184.96.......Equation 2

Ww substitute : 34 - y for x in Equation 2

6(34 - y) + 5y = 184.96

204 - 6y + 5y = 184.96

Collect like terms

- 6y + 5y = 184.96 - 204

-y = -19.04

y = 19.04 pounds

Solving for x

x = 34 - y

x = 34 - 19.04

x = 14.96 pounds

Number of pounds of cashews = x = 14.96 pounds

Number of pounds of Brazil nuts = y = 19.04 pounds

if Chelsea has 11 times as many art. Brushes and they have 60 art brushes altogether how many brushes does Chelsea have
scoundrel [369]
<span>t's call P the number of art brushes that Monique has. Chelsea has 11xP (that is 11 times as many as Monique) Together they have: P + 11xP = 12xP That means 12xP = 60 (60 is the number of art brushes they have together) In order to find how much is P, we need to divide: 60 Ă· 12 = 5 brushes P = 5 ; that means has Monique 5 art brushes. Chelsea has 11 times as many art brushes as Monique: 11 x 5 = 55 brushes</span>

Five students wrote a mathematics test. The average mark was 68. If the marks for four of the students were 75, 62, 84 and 53, t
konstantin123 [22]

Answer:

66

Step-by-step explanation:

Use the formula for the mean of a set of numbers:

                  sum of the numbers

average = --------------------------------

                     count of numbers

Here we know that the average mark was 68, so we can write:

               

                           75 + 62 + 84 + 53 + x

average = 68 = ----------------------------------

                                           5

or                            274 + x

                  68 = -------------------

                                    5

Solving for x, we multiply both sides by 5:     340 = 274 + x.

Subtracting 274 from both sides effectively isolates x:

 340 = 274 + x

- 274    -274

------------------------

  66      =    x

The fifth student's mark was 66.

Simplify.
ValentinkaMS [17]


first, you would rearrange the equation so that like terms were next to each other.

7y - 5y - x2 + 2x2 +3x - 17x

then you would reduce the equation based on like terms

2y + x2 - 14x

then simply rearrange the equation to get the answer, which is <u>B</u>
