Mr Diaz decreased the speed of his car by 30 miles per hour over a period of 10 seconds. What is the average change in the speed each second?

Answers

Answer 1

Divide 30 by 10. 30mph/10seconds = 3mph/seconds

Answer 2

Final answer:

By dividing the total change in speed (30 miles per hour) by the total time span (10 seconds), it can be determined that Mr. Diaz decreased his car's speed by an average of 3 miles per hour each second.

Explanation:

In this problem, Mr. Diaz decreased his car's speed by 30 miles per hour over a span of 10 seconds. To find the average change in speed each second, we divide the total change in speed by the total time period.

So, we can calculate the average change as follows:

30 miles per hour ÷ 10 seconds = 3 miles per hour per second

Therefore, the average change in Mr. Diaz's car speed each second is 3 miles per hour.

Help me simplify! -6 - 8(1 - x) = -14 + 8x

Answers

The answer: The equation is true. x = all real numbers.
_____________________________________________
Given:
_________________________________
-6 − 8(1 − x) = -14 + 8x ;
_________________________________
Note the "distributive property of multiplication" :
_______________________________________________a(b+c) = ab + ac ;
a(b−c) = ab − ac ;_______________________________________________As such:_______________________________________________ -8(1 − x) = (-8 * 1) − (-8*x) = (-8) − (-8x) = -8 + 8x

→ So, rewrite the original equation, substituting: "-8 + 8x" for: "−8(1 − x)" :

→ - 6 − 8 + 8x = -14 + 8x ;
Note: -6 − 8 = -14 ;

Rewrite as:

-14 + 8x = -14 + 8x ;

Solve the equation. x/8 + 12= 16

Answers

Answer:

x=32

Step-by-step explanation:

Add me on instagram at skyy.thatdancer

The value of x is 32.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 9 is an equation.

We have,

x/8 + 12 = 16

Solve for x.

x/8 + 12 = 16
Subtract 12 on both sides.

x/8 = 16 - 12

x/8 = 4

Multiply 8 on both sides.

x = 8 x 4

x = 32

Thus,

The value of x is 32.

To find the characteristic of a line.

Now, A line is a fundamental geometric concept characterized by several key properties.

Firstly, it is straight and extends infinitely in both directions.

Secondly, it has no thickness, meaning it is one-dimensional and can be represented by a mathematical equation or equation system.

Thirdly, any two points on a line can be connected to form a segment, making it possible to measure distances along the line.

Now, Additionally, a line has no endpoints, which distinguishes it from a line segment.

Lastly, lines can intersect each other at a single point or be parallel, maintaining a constant distance from one another throughout their lengths.

−dx+3x=m−9

Step 3: Factor out variable x.x(−d+3)=m−9

Step 4: Divide both sides by -d+3.

the answer is x=m-9/-d+3

plz mark brainliest

Answer:

[tex]x=\frac{m-9}{3-d}[/tex]

Step-by-step explanation:

We have been given an equation [tex]m=9+3x-dx[/tex]. We are asked to solve the given equation for x.

Subtract 9 from both sides:

[tex]m-9=9-9+3x-dx[/tex]

[tex]m-9=3x-dx[/tex]

Factor out x from right side:

[tex]m-9=x(3-d)[/tex]

Switch sides:

[tex]x(3-d)=m-9[/tex]

Divide both sides by [tex](3-d)[/tex]:

[tex]\frac{x(3-d)}{3-d}=\frac{m-9}{3-d}[/tex]

[tex]x=\frac{m-9}{3-d}[/tex]

Therefore, the value of x is [tex]\frac{m-9}{3-d}[/tex].

The ratio of girls to boys in the junior high band is 5 to 7. At the beginning of the year, there were 72 students in the band. By the end of the year, the ratio of girls to boys was 3 to 4. If there are now 48 boys in the band, how many girls joined the band during the school year?

Answers

Ratio is 5girls:7boys with total 72 students
5+7= 12
72➗12= 6
6(5:7)= 30 girls : 42 boys

New ratio is 3:4 with 48 boys

48➗4= 12

So for girls 3x12= 36

So started with 30 girls ended with 36 girls... 6 girls joined band during the school year.

A bag holds 23 3/4 cups of sugar . A recipe for chocolate chip cookies uses 1 1/4 cups of sugar . How many batches of chocolate chip cookies can be made with one bag of sugar?

Answers

You would be able to make 19 batches of chocolate chip cookies.

Final answer:

One bag of sugar can make 19 batches of chocolate chip cookies.

Explanation:

To determine how many batches of chocolate chip cookies can be made with one bag of sugar, we need to divide the total amount of sugar in the bag by the amount of sugar used in each batch of cookies. Since the bag holds 23 3/4 cups of sugar, and the recipe uses 1 1/4 cups of sugar per batch, we can set up the following division:

23 3/4 ÷ 1 1/4 = (95/4) ÷ (5/4) = (95/4) × (4/5) = 95/5 = 19

Therefore, one bag of sugar can make 19 batches of chocolate chip cookies.
