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

Total- 54.3

Step-by-step explanation:

Answer:

41.7 square meters

Step-by-step explanation:

First, rectangle A:

4 x 6 = 24 square meters

Second, rectangle B:

We know the length of this section is 3.5m. For the height/width, we can look at rectangle C. The height of C is 3.8m, and we see the part of C that is NOT part of B is 2m long. So we subtract 2 from 3.8 to find the height of B.

3.8 - 2 = 1.8m

Then, for the area of B:

3.5 x 1.8 = 6.3 square meters

Third, rectangle C:

3 x 3.8 = 11.4 square meters

Add up areas of A, B, C:

24 + 6.3 + 11.4 = 41.7 square meters

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.

A car costs $30,000 when purchased as new and depreciates at a rate of 18% per year.

1. Write an exponential decay model to represent the situation. Be sure to define the variables.
2. Find the value of the car after 10 years.

Answers

9514 1404 393
Answer:
v(t) = 30000×0.82^t . . . value in dollars after t years
v(10) ≈ 4123 . . . . dollars
Step-by-step explanation:
The general form of the decay model is ...
f(t) = f(0)×(1 -decay rate)^time
where the decay rate is a fraction between 0 and 1, and the time is expressed in the same time units as the decay rate. The multiplier f(0) is the initial value that is decaying.
In this problem, the initial value is $30,000 and the decay rate is 18% per year. So, we can write a function v(t), where v is the car's value in dollars, and t is the number of years after it starts depreciating.
v(t) = 30,000×(1 -0.18)^t
v(t) = 30,000×0.82^t
__
The car's value in 10 years is ...
v(t) = 30,000×0.82^10 ≈ 4123.44
The value of the car after 10 years is about $4,123.

That being said we can use this equation to solve for x

40 = 5x

Objective: Isolate the variable using inverse operations

To get rid of the 5 we divide each side by 5

40 / 5= 8

5x/5=x

we're left with x=8

To check our answer we can plug in 8 to x and if it equal 40 then the answer is correct

5(8) = 40

So the answer would be 8

8

OWA OWA

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.
