Answer:

Step-by-step explanation:

A pencil in the picture shows a segment with a definite length.

We may get confused with the difference in a line and segment.

A line is defined by a line of points that extends infinitely.

That means both the ends of a line are not defined.

But a segment is a part of line which has a definite length between two defined ends.

Therefore, unsharpened pencil defines the term line segment which is a defined term.

Answer:

The unsharpened pencil suggests the term line segment, which is a defined term.

Answer:

x = 5/2

Step-by-step explanation:

Solve for x:

(5 x)/2 = 25/4

Hint: | Multiply both sides by a constant to simplify the equation.

Multiply both sides of (5 x)/2 = 25/4 by 2/5:

(2×5 x)/(5×2) = 2/5×25/4

Hint: | Express 2/5×5/2 as a single fraction.

2/5×5/2 = (2×5)/(5×2):

(2×5)/(5×2) x = 2/5×25/4

Hint: | Express 2/5×25/4 as a single fraction.

2/5×25/4 = (2×25)/(5×4):

(2×5 x)/(5×2) = (2×25)/(5×4)

Hint: | Cancel common terms in the numerator and denominator of (2×5 x)/(5×2).

(2×5 x)/(5×2) = (5×2)/(5×2)×x = x:

x = (2×25)/(5×4)

Hint: | In (2×25)/(5×4), divide 25 in the numerator by 5 in the denominator.

25/5 = (5×5)/5 = 5:

x = (2×5)/4

Hint: | In (2×5)/4, divide 4 in the denominator by 2 in the numerator.

2/4 = 2/(2×2) = 1/2:

Answer:

453.6

Step-by-step explanation:

226.8 x 2 = 453.6

The mass of two rolls of quarters is 453.6 grams.

It is required to find the mass of two rolls of quarters.

The branch of mathematics dealing with the properties and manipulation of numbers. a science that deals with the addition, subtraction, multiplication, and division of numbers. Fractions, decimals, percentages, fractions, square root, exponents, and other arithmetic operations are used to achieve mathematical simplifications.

Given:

One quarter has a mass of 5.67 grams

mass of each quarter=40 quarters

The mass of 80 quarters will be 80 times the mass of 1 quarter:

 80 × 5.67 g = 453.6 g

Hence, the mass of two rolls of quarters is 453.6 grams.

8 / -2 * 42 + 9

~Divide

-4 * 42 + 9

~Multiply

-168 + 9

~Add

177

Best of Luck!

The simplified expression is equivalent to -159.

Given is an expression 8 ÷ -2 · 42 + 9, we need to simplify it,

To evaluate the expression 8 ÷ -2 · 42 + 9, we need to follow the order of operations, which is typically remembered using the acronym PEMDAS.

In this case, we should first perform the multiplication and division, and then the addition.

Starting with the multiplication and division:

8 ÷ -2 = -4

-4 · 42 = -168

Now we can add the result to 9:

-168 + 9 = -159

Therefore, the evaluation of 8 ÷ -2 · 42 + 9 is -159.

Question 23

Step-by-step explanation:

When the question says a line bisects an angle which means that this line is cut exactly at the centre of an angle so both angles will be the same :

Question 21,

[tex]∠PQR = ∠SQR[/tex]

[tex]∠PQS = 22°[/tex]

[tex]∠PQR = ∠PQS + ∠SQR[/tex]

[tex]∠PQR = 22 + 22 = 44°[/tex]

Answer:

60 muffins

Step-by-step explanation:

Muffins = 6 per package

Cookies = 20 per package

His Baker realized they sold the same amount of muffins and cookies yesterday

What is the minimum amount of muffins that were sold yesterday?

To find the minimum amount of muffins sold, find the lowest common multiple of 6 muffins per package and 20 cookies per package

6 muffins per package = 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84

20 cookies per package = 40, 60, 80, 100, 120

The lowest common multiple of of 6 muffins per package and 20 cookies per package is 60.

Therefore, the minimum amount of muffins sold yesterday was 60 muffins.

The equation 7 = 2y + 9 is equivalent to -3 = 2y + 1 and  -2 = y – 1 option (a) and (c) are correct.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that equation:

7 = 2y + 9

After simplification:

2y = 7 - 9

2y = -2

y = -1

a.) -3 = 2y + 1

After simplification:

2y = -3 - 1

2y = -4

y = -1

b.) 8 = 9y - 1

After simplification:

9y = 1 + 8

9y = 9

y = 1

c.) -2 = y – 1

After simplification:

y = -2 + 1

y = -1

d.) -4 = 2y + 6

After simplification:

2y = -4 - 6

2y = -10

y = -5

Thus, the equation 7 = 2y + 9 is equivalent to -3 = 2y + 1 and  -2 = y – 1 option (a) and (c) are correct.
