malfutka [58]

Answer:

$\huge \boxed{x=-11}$

Step-by-step explanation:

First, divide by 2 from both sides of equation.

$\displaystyle \frac{2(x+6)}{2}=\frac{-10}{2}$

Then, solve.

$\displaystyle x+6=-5$

Subtract by 6 from both sides of equation.

$\displaystyle x+6-6=-5-6$

Solve to find the answer.

$\displaystyle x=-11$ , which is our answer.

Ken's fitness member ship cost $100 to join plus a $25 monthly fee. Ken also used a coupon to get 10% off the monthly fee. What

GREYUIT [131]

The equation that models the total cost is y = 100 + 22.5m

Step-by-step explanation:

Fitness member ship cost = $100

Monthly fee = $25

Discount = 10% on monthly fee

To calculate new monthly fee after discount,

25 - (25*10%) --> 25 - 2.5 --> $22.5

Number of months = m

Fee in m months = 22.5*m = 22.5m

<u>Equation:</u>

(x) is the monthly fee $22.5

(m) is the number of months

(y) is the total cost

So,

y = mx + c

y = m(22.5) + 100

y = 100 + 22.5m

Therefore, the equation that models the total cost is y = 100 + 22.5m

Lúcia is using energy at a rate of 420 kilocalories (kcal) per hour (h) ice skating.

kakasveta [241]

Answer:

7000 cal/min

Step-by-step explanation:

It is mentioned that, Lucia is using energy at a rate of 420 kilo calories per hour ice skating

We know that,

1 kilo calories = 1000 calories

Using unitary method :

420 kilo calories = 420,000 calories

Also,

1 hour = 60 minutes

In this case, Lucia is using energy per 60 minutes = 420,000 calories. So,energy used by her per minute is :

$E=\frac{420000}{60} =7000 calories$

Hence, Lucia is using 7000 calories per minute.
