Answer 1

The value of equation 4-2(x+7)=3(x+5) is that x=-5/7.

Given equation 4-2(x+7)=3(x+5)

We are required to solve the equation for the value of variable x.

Equation is relationship between two or more variables expressed in equal to form.Equation of two variables looks like ax+by=c. It can be a linear equation,quadratic equation, cubic equation. It can be solved for finding the value of variables.

The given equation is 4-2(9x+2)=3(x+5)

It is a linear equation.

We have to first remove the brackets by multiplying the numbers to inside numbers.

4-18x-4=3x+15

Now collect variable x at one end and constant at other end.

-18x-3x=15-4+4

-21x=15

x=-15/21

x=-5/7

Hence the solution of equation 4-2(x+2)=3(x+5) is that x=-5/7.

A 36 ounce box of cereal costs $3.50. Find the unit price.

Answers

$0.0972

I think.

Um this is to make it long enough to post. lol

Answer:

Approximately $0.10 per ounce

Step-by-step explanation:

Hi! :) I'm assuming this problem is asking for the price per ounce? If not, I apologize.

So, in order to determine the price of cereal per ounce we would simply divide $3.50 by 36 to find the cost per ounce.

$3.50 / 36 = approximately $0.09722222 which we can round up to $0.10.

Find the area of the inner and the outer circles, shown in the figure below. Use 3.14 for pi.

Answers

The radius of the outer circle is 17 so you put that in the formula to find the area of a circle and solve to get 153.86 squared meters as the final answer. The radius of the inner circle is 7 because it shows that the upper part of the circle is 10 and the whole thing is 17, so you do 17-10 to get 7 as the radius. Then put it in the formula and get the final answer as 907.46 squared meters.

A large block of ice is melting and losing 5 grams of mass every minute. After 11 minutes, the ice has lost 70 grams. Assume the relationship is linear.

Answers

The linear equation of line is given by y = 6.5x - 1.5 where the slope of the equation m = 6.5 , y = amount of ice lost and x = time elapsed

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the amount of ice lost = y

Let the time elapsed be = x

A large block of ice is melting and losing 5 grams of mass every minute

So , the first point be A = A ( 1 , 5 )

After 11 minutes, the ice has lost 70 grams

So , the second point is B = B ( 11 , 70 )

Now , the slope of the line is given by the formula ,

Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 70 - 5 ) / ( 11 - 1 )

Slope m = 65/10

Slope m = 6.5

Now , the equation of line is given by ,

y - y₁ = m ( x - x₁ )

Substituting the values in the equation , we get

y - 5 = 6.5 ( x - 1 )

y - 5 = 6.5x - 6.5

Adding 5 on both sides of the equation , we get

y = 6.5x - 1.5

Therefore , the value of A is y = 6.5x - 1.5

Substitute the value of x = 11 minutes , we get

y = 6.5 ( 11 ) - 1.5

y = 71.5 - 1.5

y = 70 grams

Hence , The linear equation of line is given by y = 6.5x - 1.5 where the slope m = 6.5
