How many solutions does the following equation has?
5 (m - 3) + 6 = 4m + 3

A-No Solution
B-Infinitely Many Solutions
C-One Solution

Answers

B should be the answer . Sorry if I’m wrong

Answer:

C. One Solution

That one solution is "m = - 6"

Step-by-step explanation:

5m - 3 + 6 = 4m + 3

Subtract 3 from each side:

5m - 3 - 3 + 6 = 4m + 3 - 3

5m + 6 = 4m

Subtract 6 from both sides of the equation:

5m + 6  - 6 = 4m - 6

5m = 4m - 6

Subtract 4m from both sides of the equation:

5m - 4m = 4m - 4m - 6

m = - 6

The equation that relates the number of campers this year to the number of campers last year is c = 440 / 1.10

The number of campers last year is 400.

What are percentages?

Percentage can be described as a fraction out of an amount that is usually expressed as a number out of hundred. Percentages are used to measure frequency.

Given that, a summer camp had 440 campers register this year, this is a 10 % increase over the number registered last year.

So,

The number of campers last year = number of campers this year / (1 + percentage increase)

440 / 1.1 = 400

Hence, the equation that relates the number of campers this year to the number of campers last year is c = 440 / 1.10 and number of campers last year is 400.

Answers

Answer:

330cm

Step-by-step explanation:

The formula to find the surface area of a rectangular prism is 2(lh+hw+lw)

(lh) in this formula is length times height

(hw) is height times width

(lw) is length times width

To find the answer to this problem lets make the height 3/5cm the width 10cm and the length 15cm

so now you would do (15*3/5) which is 9. This solve (lh)

then you would find (3/5*10) which is 6. This solves (hw)

and lastly you would find (15*10) which is 150. This solves (lw)

Now that you now the value of each one of these you replace it in the equation as so: 2(9+6+150)

now you solve the brackets which leaves us with 2(165)

now you multiply 2 with 165

and the answer is 330cm

Surface area = 330cm

Please answer the following with 5 or more sentences:
The diameter of a circle is tripled. How does that affect the circumference? How does that affect the area? Explain.

Answers

Answer:

The formula for the circumference is 2πr. If you triple the radius the formula would be 2π3r. the ratio between the two is 2π3r / 2π1r. 2π & r cancels out and you have 3/1 left. Therefore the answer is the circumference is tripled.

The fact that there is no exponential in the formula indicates that the proportional increase is lineal.

The Circumference is 2πr.

When the radius is x, the circumference is 2πx

When the radius is tripled, it becomes 3x, to the circumference will be 2π(3x) = 6πx.

Soooooooo the circumference will also be tripled.
