Nesterboy [21]

Answer:

The system of equation can be used for determine the number of small and the large dogs groomed are

x + y = 22

43x + 75y = 1234

Step-by-step explanation:

Let us assume that the number of small dogs groomed be x.

Let us assume that the number of lagre dogs groomed be y.

As given

Paws at play made a total of $1,234 grooming 22 dogs.

Than the equation becomes

x + y = 22

Paws at play charges $43 to groom each small dog and $75 for each large dog.

Than the equation becomes

43x + 75y = 1234

Therefore the system of equation can be used for determine the number of small and the large dogs groomed are

x + y = 22

43x + 75y = 1234

jek_recluse [69]

Answer:

There is a total of 45 members in the math club.

Step-by-step explanation:

What I did is I multiplied 9 by 5 and got 45. I multiplied 9 by 5 because the question stated that 9 students are 20%. 20% times 5 would be 100%, which would be the total number of students.

Hope this helped :)

I willll GIVE A BRAN....
blsea [12.9K]

Answer: Choice C

The first inequality is 124+121+x \ge 400

The second inequality is x \ge 155

Replace x with whatever letter your teacher is using

=========================================================

Let x be the number of cans collected on week 3

Add this to the previous totals (for weeks 1 and 2) to get 124 + 121 + x. I'm going to leave this as is and not simplify. This is so the answer matches up. This total must be greater than or equal to 400, meaning 124+121+x can be 400 or larger.

124+121+x >= 400

245+x >= 400 .... combine like terms

x >= 400-245 .... subtract 245 from both sides

x >= 155

So you need to collect at least 155 cans for the third week so that you'll have at least 400 cans total.
