I Need Help On Knowing Whether This Is A Solvable Equation. Along With Reasons Why. HELP IF YOU CAN :))

Answers

Answer 1

To check if x = 9 is the solution, we need to replace every x with 9 and simplify

(3+x)/4 = 3

(3+9)/4 = 3

12/4 = 3

3 = 3

We get the same thing on both sides, so the last equation is a true equation. This means that the first equation is a true equation when x = 9. Therefore, the solution x = 9 is confirmed.

6. If A= 4, and B = 5, what is length of the hypotenuse? Show all work

Answers

Answer:

The formula is a^2 + b^2 = c^2

Step-by-step explanation:

A and B are legs and C is the hypothunisis.

The theorem is used for triangles.

4^2  + 5^2 = c^2

16 + 25 = c^2

41 = c^2

sqr(41) = sqr(c)^2

c = 6.403124237

Stuff mart sells ice cream toppings in two different packages. Package one has eight blueberry toppings for $22. Package two has four blueberry and seven strawberry toppings for $22. Find the cost of each topping

Answers

Answer:

the cost of the blueberry packing be $2.75 and the cost of the strawberry topping be $1.57

Step-by-step explanation:

The computation is shown below:

Let us assume the blueberry topping be x

And, the strawberry topping be y

Now as per the question

8x = $22

Divide by 2 to the both sides

4x = $11

x = $11 ÷ 4

= $2.75

And,

4x + 7y = $22

Now put the x value in the above equation

4 × (11 ÷ 4) + 7y = $22

11 + 7y = $22

7y = $22 - $11

7y = $11

y = $11 ÷ 7

= $1.57

Hence, the cost of the blueberry packing be $2.75 and the cost of the strawberry topping be $1.57
