A town has accumulated 2 inches of​ snow, and the snow depth is increasing by 6 inches every hour. A nearby town has accumulated 7 ​inches, and the depth is increasing by 3 inches every hour. In about how many hours will the snowfall of the towns be​ equal?

Answers

Answer 1
You basically make an equation out of this and set the two expressions equal to each other.

Let x equal the number of hours where the snowfall will be equal in both towns.

In town one, the amount of snowfall can be written as 2+6x. In town two, the amount of snowfall can be written as 7+3x.

So to find when they will be equal, set them equal and solve:

2+6x=7+3x
3x=5
x=5/3 or 1 2/3 hours. In minutes, this is 100 minutes.

Which of the following is the product (5y − 3)2?

Answers

Answer:

= 10y − 6 is your answer

Step-by-step explanation:

option B is correct, 25y²-30y+9 is the product of (5y − 3)².

What is Expression?

The combination of numbers, variables, and operators is known as Expression.

The given expression is (5y − 3)²

The process of determining the product of two or more numbers is Multiplication.

The expression is five times of y minus three to the power of two.

From algebraic identity we have (a-b)²=a²+b²-2ab

Now (5y − 3)²

(5y)²+3²-2(5y)(3)

25y²+9-30y

Twenty five y to the power of two plus nine minus thirty times of y.

25y²-30y+9 is the expression after product of  (5y − 3)².

Hence, option B is correct, 25y²-30y+9 is the product of (5y − 3)².

C. A(x) = 4x^2 + 20x + 96

D. A(x) = 4x^2 + 40x + 96

Answers

Answer:

D: A(x) = 4x² + 40x + 96

Step-by-step explanation:

Dimensions of photo is;

Length; L = 12 inches

Width; W = 8 inches

Now, this picture is surrounded by a frame that is "x" inches wide. Thus, new dimensions are;

L_new = 12 + x + x = 2x + 12

W_new = 8 + x + x = 2x + 8

New area is;

A_new = (2x + 12) × (2x + 8)

A_new = 4x² + 24x + 16x + 96

A_new = 4x² + 40x + 96

Answers

Answer:

y = -6/5x + 1

Step-by-step explanation:

The equation that represents a line with a slope of -6/5 and a y-intercept of 1 is y = -6/5x + 1

How to determine the equation?

The given parameters are:

Slope, m = -6/5y-intercept = 1

Let the variable of the equation be x.

A linear equation is represented as:

y = Slope * x + y-intercept

So, we have:

y = -6/5 * x + 1

Evaluate

y = -6/5x + 1

what number is halfway between 8.270 and 8.280? The answer is 8.275 hope this helps

Answers

Answer:

8.275

Step-by-step explanation:

8.280 - 8.270 = 0.010

0.010/2 = 0.005

8.270 + 0.005 = 8.275

The number halfway between 8.270 and 8.280 is 8.275.

What is Arithmetic?

The study and use of numbers, their connections, and mathematical observations are topics covered by the area of mathematics known as arithmetic. The fundamental ideas in number theory, measurement, and calculation are frequently referred to as "arithmetic" (which is derived from the Greek word "arithmos," "number") (that is, the processes of addition, subtraction, multiplication, division, raising to powers, and extraction of roots).

As per the given data:

We have to find the number which is halfway between 8.270 and 8.280.

For finding the number, we can calculate the difference between 8.270 and 8.280 and then divide it by two now we can add the obtained number into 8.270 to get the number.

[tex]\frac{8.280 - 8.270}{2}[/tex]

= [tex]\frac{0.010}{2}[/tex]

= [tex]0.005[/tex]

The number halfway between 8.270 and 8.280:

8.270 + 0.005

= 8.275

Hence, the number halfway between 8.270 and 8.280 is 8.275.

How many solutions does 3(x + 5) – 3 = 2(3x + 1) – 3x have? Show your work.

Answers

Answer: There are no solution

Step 1: Simplify both sides of the equation.

3(x+5)−3=2(3x+1)−3x

(3)(x)+(3)(5)+−3=(2)(3x)+(2)(1)+−3x(Distribute)

3x+15+−3=6x+2+−3x

(3x)+(15+−3)=(6x+−3x)+(2)(Combine Like Terms)

3x+12=3x+2

3x+12=3x+2

Step 2: Subtract 3x from both sides.

3x+12−3x=3x+2−3x

12=2

Step 3: Subtract 12 from both sides.

12−12=2−12

0=−10

After solving the equation, the value obtained for x is 0, which means that there is no solution for the equation.
