Answer:

x=9

Step-by-step explanation:

Distribute -3 into (x-5)

-3x+15+4x=24

then combine like terms

x+15=24

isolate the variable and subtract 15 from both sides

x=9

Answer:

Step-by-step explanation:

-3(x-5)+4x=24

Multiply the -3 with the stuff in the ( ) and you get -3x+15 since a negative and a negative equal a positive the 15 is positive so now you have -3x+15+4x =24 now you add like terms and you have 1x+15=24 then -15 from both sides so 15-(-15) cancels out then 24-15=9 then you have 1x=9 divide the 1x end the answer is x=9

A rental car agency charges $30.00 per day

lutik1710 [3]

<h2>Answer:</h2><h2>They should travel 120 mils in one day for both rental agencies to cost the same amount to rent</h2>

Step-by-step explanation:

A rental car agency charges $30.00 per day plus per mile $0.15.

Let x be the number of miles travelled by car

Their total cost = 30 + (0.15x) ... (1)

Another rental car agency charges $36.00 per day plus $0.10 per mile

Their total cost = 36 + (0.10x) ... (2)

Equating (1) and (2), we get

30 + (0.15x) = 36 + (0.10x)

36 - 30 = 0.15x - 0.10x

6 = 0.05x

x = 120 miles

They should travel 120 mils in one day for both rental agencies to cost the same amount to rent

Karen gave an equal amount of m and m's to herself and four friends. Each person receives m and m's equivalent to the largest on

Mariana [72]

Answer:

Karen had 45 m and m's candy.

Step-by-step explanation:

Let the number of m and m's candy be 'x'.

Now given:

Karen gave an equal amount of m and m's to herself and four friends.

So we can say that;

Number of people m and m's candy distributed equally = 5

Also Given:

Each person receives m and m's equivalent to the largest one digit number.

Now we know that;

Largest one digit number is 9.

So we can say that;

Each person receives m and m's = 9

We need to find number of m and m's Karen have.

Solution:

So we can say that;

Total number of m and m's Karen have is equal to Number of people m and m's candy distributed equally multiplied by number of m and m's can each person receives.

framing in equation form we get;

Total number of m and m's Karen had = $9\times5 = 45$
