robert is purchasing some equipment for his baseball team. he wants to buy some baseballs, each priced at m dollars. he has already spent b dollars on other equipment.

the following expression represents the total amount robert will spend after buying x baseballs.

if the amount already spent by robert on other equipment, b dollars, is doubled, then the value of m .

if the cost of each baseball, m dollars, is tripled, then the value of b and the value of mx will

Part A: (1/2)m

Part B: (1/3rd)b and 3mx

Step-by-step explanation:

Price of each baseball is=$m

Price of other equipment are=$b collectively

Total amount He spent on purchasing equipment is =(m+b)$

Part A:

in part A the amount on purchasing other equipment than baseball is getting doubled i.e. $2b then value of m will be (1/2)half of the total amount spent on purchasing baseball i.e. (1/2)m

Part B:

in part B the amount spent on purchasing baseball is getting tripled i.e. 3m, then value of b(amount of purchasing other equipment) is (1/3rd) of total amount spent on purchasing other equipment and value of mx will be 3mx

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3
