Tom and his best friend are going to join a gym. Tom saw that Platinum gym has a sale with a one time fee of $90 and a monthly f

worty [1.4K]

Answer:

Part 1:

For Platinum Gym:

90 + 30x

For Super Fit Gym:

200 + 20x

Part 2: $270

Part 3: $320

Part 4: 11 months

Part 5: See explanation below

Step-by-step explanation:

Part 1:

Let "x" be the number of months:

For Platinum Gym:

90 + 30x

For Super Fit Gym:

200 + 20x

Part 2:

We put x = 6 in platinum gym's equation and get our answer.

90 + 30x

90 + 30(6)

90 + 180

=$270

Part 3:

We put x = 6 into super fit's equation and get our answer.

200 + 20x

200 + 20(6)

200 + 120

=$320

Part 4:

To find the number of months for both gyms to cost same, we need to equate both equations and solve for x:

90 + 30x = 200 + 20x

10x = 110

x = 11

So 11 months

Part 5:

We know for 11 months, they will cost same. Let's check for 10 months and 12 months.

In 10 months:

Platinum = 90 + 30(10) = 390

Super Fit = 200 + 20(10) = 400

In 12 months:

Platinum = 90 + 30(12) = 450

Super Fit = 200 + 20(12) = 440

Thus, we can see that Platinum Gym is a better deal if you want to get membership for months less than 11 and Super Fit is a better deal if you want to get membership for months greater than 11.

The rephrased statement for Kun's proof is: A. In quadrilateral ABCD, if AB ≅ DC & AD ≅ BC, then AB║DC & AD║BC.

<h3>What is a Parallelogram?</h3>

A parallelogram is a quadrilateral that has two opposite sides that are congruent to each other and are also parallel to each other.

This means that if two pairs of opposite sides of a quadrilateral are congruent and parallel, then it is a parallelogram.

Rephrasing Kun's statement in his proof will therefore be: A. In quadrilateral ABCD, if AB ≅ DC & AD ≅ BC, then AB║DC & AD║BC.

Evaluating expressions: 1. x + 9 when x = 3

balu736 [363]

⇨ The numeric value of this expression = 12.

To solve this expression, just replace 'x' by the indicated value, being the number 3, and perform the indicated math operations.

${\large \displaystyle \sf {1 \cdot x+9 }}$

${\large \displaystyle \sf {x=3 }}$

${\large \displaystyle \sf {1 \cdot 3+9 }}$

${\large \displaystyle \sf { 3+9 }}$

${\orange{\boxed{\boxed{\pink {\large \displaystyle \sf { \ 12 \ }}}}}}\\\\$

Therefore, we can conclude that, the correct value of this expression = 12.

${\orange{\boxed{\boxed{\pink {\large \displaystyle \sf { \ 12 \ }}}}}}\\\\$
