Anyone know the answer to these?

3) 4x=15

6)b=$2.5

1) n= -12

Step-by-step explanation:

3. Given the equation ,

#Expand by removing the brackets:

#We then group the like terms to solve for x:

2+4x=17

4x=15

Hence, the equations equivalent is 4x=15

6. Let b be the cost of each bag of snack.

-Given that there are 4 friends who spent a total of $34 and each ticket costed $6.

-We equate the costs to the total to solve for b:

Hence, the cost of each bag of snack is $2.5

1) Given the equation

#First. we multiply each term by 3 to remove the fraction:

#We then group like terms together to solve for n:

#Divide all terms by -2 to get the value of n:

Hence n= -12

answer: idk

step-by-step explanation:

you can use a^2+ b^2=c^2
