A college student has $240 to use for laundry money. Each time he does laundry, he spends $7.50. Which equation represents the a
Lady bird [3.3K]

Answer:

B

Step-by-step explanation:

x = the number of times he does laundry.

Let's say he does the laundry 5 times then x = 5.

Each time costs $7,50.

If you want to know how much money he has spent after 5 times, you have to calculate 5 times $7,50. 7,5 times 5 = 37.5.

M stands for how much money he still has left from the 240 dollars.

If you apply the formula it would be 'M = 240 - 7.50x (7.50 times 5) = 240 - 37.5 = 202.5'

Therefore, the correct answer is B (M = 240 - 7.50x).

How do you know if a girl like you and what is x+10 divided by 6 = 1
strojnjashka [21]

Answer:

x = -2/3

Step-by-step explanation:

x + 10 ÷ 6 = 1

Divide

x + 1 2/3 = 1

Subtract 1 2/3

x = -2/3

Also, as a girl, we do give some signs to people that we like, we start conversations with the person, we make eye contact and then look away (at least that what I do lol), flirts with you, agrees with you, wants to spend time with you, etc.
