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

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).

12m

step-by-step explanation:

square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get your answer!
