Mathematics
1 answer:
Simora [160]3 years ago
4 0

<u><em>Answer:  c=-12. *The answer must have a negative sign.*</em></u>

Explanation:

First, you had to do is divide by -3 from both sides of an equation.

\frac{-3c}{-3}=\frac{36}{-3}

And then, you simplify.

36/3=12

You can also multiply by the numbers.

12*3=36

3*12=36

c=-12

Hope this helps!

pickupchik [31]

The total cost is $43.5 and it is obtained from the equation c = 6.5n + 25

<u>Solution:</u>

Given that, while your family is visiting Deep creek lake, you and your mother decide to go boating.  

The Rangers charge $6.50 per hour in addition to $25.00 deposit to rent a canoe.  

If you wish to rent the canoe from 12:30 to 3:30 PM,  

We have to write and solve a linear equation to find the total cost to rent the canoe.

Now, we know that,

<em>total cost = charges + rent fee </em>

\text {Total cost }=\text { number of hours used } \times \$ 6.5 \text { per hour }+\$ 25

Let total cost be "c" and number of hours rented be "n"

\begin{array}{l}{c=n \times 6.50+25} \\\\ {c=6.5 n+25 \rightarrow(1)}\end{array}

Now, they used canoe from 12:30 to 3:30, which means 3 hours of time

So, put n = 3 in (1)  

c = 6.5(3) + 25

c = 19.5 + 25

c = 43.5

Hence, the total cost is $43.5 and it is obtained from the equation c = 6.5n + 25

How would I solve for x?​
vaieri [72.5K]

Answer:

x = 65

Step-by-step explanation:

First, we calculate the unknown angle of the left triangle and right triangle:180 - 62 - 50 = 68

Unknown angle for left triangle⬆️

180 - 80 - 53 = 47

Unknown angle for right triangle⬆️

Now we've calculated the two angles for the small triangle in the middle. So, we just have to calculate the top angle of the middle triangle:

180 - 68 - 47 = 65

The angle 65° and angle of x are vertical angle.(both are equal)

So... <u>x= 65°</u>

The perimeter of a rectangle is 25 2/5 ft. The length is
Naya [18.7K]

Answer:

Width = 4.85 feet

Length = 7.85 feet

Step-by-step explanation:

Given:

Perimeter of a rectangle = 25 2/5 ft = 25.4 feet

Length = 3 + Width

Computation:

Assume;

Width = a

So,

Length = 3 + a

Perimeter of a rectangle = 2(l + b)

25.4 = 2[(3 + a) + a]

25.4 = 2[3 + 2a]

25.4 = 6 + 4a

4a = 19.4

a = 4.85

Width = 4.85 feet

Length = 3 + 4.85

Length = 7.85 feet
