Answer:

x = 9/2

Step-by-step explanation:

Solve for x:

4 (5 - 8 x) = -24 x - 16

Expand out terms of the left hand side:

20 - 32 x = -24 x - 16

Add 24 x to both sides:

24 x - 32 x + 20 = (24 x - 24 x) - 16

24 x - 24 x = 0:

24 x - 32 x + 20 = -16

24 x - 32 x = -8 x:

-8 x + 20 = -16

Subtract 20 from both sides:

(20 - 20) - 8 x = -20 - 16

20 - 20 = 0:

-8 x = -20 - 16

-20 - 16 = -36:

-8 x = -36

Divide both sides of -8 x = -36 by -8:

(-8 x)/(-8) = (-36)/(-8)

(-8)/(-8) = 1:

x = (-36)/(-8)

The gcd of -36 and -8 is -4, so (-36)/(-8) = (-4×9)/(-4×2) = (-4)/(-4)×9/2 = 9/2:

Answer:  x = 9/2

SORRY DONT KNOW

Step-by-step explanation:

the measure of angle ∠21 must be 55 degrees for line b to be parallel to line a.

In order for line b to be parallel to line a, the measure of angle ∠21  must be 125 degrees. Corresponding angles are angles that are in the same position relative to two intersecting lines. Since lines a and b are parallel, we know that corresponding angles ∠1 and ∠21 are congruent.  Therefore, we can set up the following equation to find the measure of ∠21:

∠1 + ∠21 = 180° (because they are supplementary angles)

Substituting 125° for the measure of ∠1, we get:

125° + ∠21 = 180°

Solving for ∠21, we get:

∠21 = 180° - 125°

∠21 = 55°

Final answer:

The sum of the binary numbers 110two and 111two is 1101two, which is equivalent to 13 in decimal form.

Explanation:

The question asks for the sum of two binary numbers: 110two and 111two. To add these two binary numbers, we align them by their least significant bits and perform binary addition:

110

+ 111

-----

1101

This is equivalent to the decimal addition of 6 (110two) + 7 (111two) which equals 13. In binary, 13 is represented as 1101two.

There are approximately 2/7  7/10s in 1/5.

The calculation step by step to find out how many 7/10s are there in 1/5.

1. We have two fractions:

[tex]- \( \frac{7}{10} \)[/tex]

[tex]- \( \frac{1}{5} \)[/tex]

2. To compare these fractions, we need to make their denominators the same. The least common multiple (LCM) of 10 and 5 is 10.

3. Convert both fractions to have a denominator of 10:

[tex]- \( \frac{7}{10} \)[/tex] remains the same.

[tex]- \( \frac{1}{5} \) becomes \( \frac{2}{10} \) (since \( \frac{1}{5} = \frac{2}{10} \)).[/tex]

4. Now, let's divide [tex]\( \frac{2}{10} \) by \( \frac{7}{10} \)[/tex]:

[tex]- \( \frac{2}{10} \div \frac{7}{10} \)[/tex]

- Multiply by the reciprocal of the second fraction:

[tex]\( \frac{2}{10} \cdot \frac{10}{7} \)[/tex]

 - Multiply the numerators:[tex]\( 2 \cdot 10 = 20 \)[/tex]

- Multiply the denominators: [tex]\( 10 \cdot 7 = 70 \)[/tex]

[tex]- The result is \( \frac{20}{70} \), which simplifies to \( \frac{2}{7} \).[/tex]

5. Therefore, there are approximately 2/7 7/10s in 1/5.

Answer:

Step-by-step explanation:

Given

F = [tex]\frac{9}{5}[/tex](K - 273.15) + 32

Multiply through by 5 to clear the fraction

5F = 9(K - 273.15) + 160 ( subtract 160 from both sides )

5F - 160 = 9(K - 273.15) ← distribute

5F - 160 = 9K - 2458.35 ( add 2458.35 to both sides )

5F + 2298.35 = 9K ( divide both sides by 9 )

K = [tex]\frac{5F+2298.35}{9}[/tex]

(b)

When F = 180, then

K = [tex]\frac{5(180)+2298.35}{9}[/tex]

   = [tex]\frac{900+2298.35}{9}[/tex]

   = [tex]\frac{3198.35}{9}[/tex]

Answer:

Positive 15

Step-by-step explanation:

Answer:

15

Step-by-step explanation:

Answer:

L = 15

Step-by-step explanation:

P = 2L + 2W

you know that P = 50, W=10

So you have to replace those values on the equation

50 = 2L + 2*(10)  --> Replace P and W

50 = 2L + 20  --> Multiply and now you are going to separate the unknown and the constants.

Remember that if you send a constant to the other side of the equal the sign will change to its opposite

50 - 20 = 2L  --> Solve the constants

30 = 2L    --> Now for the L, you have to leave it alone, so the 2 that is multiplying you have to send it to the other side of the equal but with the opposite operation,  the opposite operation of multiplying is dividing, so you have:

30/2 = L

L= 15

The relationship in each table is that each number is obtained by adding 2 to the previous number.

The relationship between the numbers in the first table is that each number is obtained by adding 2 to the previous number. The expression to describe this relationship is n + 2, where n is any given number in the table.

The relationship between the numbers in the second table is that each number is obtained by adding 2 to the previous number. The expression to describe this relationship is n + 2, where n is any given number in the table.

The domain of the function F(x) = √(x+4) is all real numbers greater than or equal to -4, which corresponds to option C. x≥-4.

The student has asked about the domain of the function F(x) = √(x+4). To determine the domain of this function, we need to consider the values of x for which the expression under the square root, x+4, is non-negative, since the square root of a negative number is not defined in the set of real numbers.

The expression x+4 is non-negative when x ≥ -4. Therefore, any number greater than or equal to -4 is part of the domain of the function.

This means the correct answer to the question is C. x≥-4.

Hope This Helped! Good Luck!

Answer:

The required expression is [tex] O=h - 40[/tex].

For 40 hrs overtime is 0 hrs.

For 44 hrs overtime is 4 hrs.

For 48 hrs overtime is 8 hrs.

For 52 hrs overtime is 12 hrs.

Step-by-step explanation:

Consider the provided information.

Part (A)

It is given that Jim is paid for overtime when he works more than 40 hours per week.

Let Jim works for h hrs and O represents the overtime, Then overtime can be represented as:

O = h - 40

The expression for the number of hours he works overtime when he works h hours is:

[tex] O=h - 40[/tex]

Part (B) Find the number of hours Jim works overtime when he works 40, 44, 48, and 52 hours.

Substitute h=40 in the obtained expression.

[tex] O=40 - 40[/tex]

[tex] O=0[/tex]

Hence, for 40 hrs overtime is 0 hrs.

Substitute h=44 in obtained expression.

[tex] O=44 - 40[/tex]

[tex] O=4[/tex]

Hence, for 44 hrs overtime is 4 hrs.

Substitute h=48 in obtained expression.

[tex] O=48 - 40[/tex]

[tex] O=8[/tex]

Hence, for 48 hrs overtime is 8 hrs.

Substitute h=52 in obtained expression.

[tex] O=52 - 40[/tex]

[tex] O=12[/tex]

Hence, for 52 hrs overtime is 12 hrs.

Answer:

Step-by-step explanation:

The difference would mean that it is subtraction and you multiply that difference by 4 and set it equal to b squared

According to the statement, the given equation is  4(b - 6) = b², and the value of b is 2 + 4.472i and 2 - 4.472i.

To solve the equation given: 4(b - 6) = b², we need to first expand and simplify.

4b - 24 = b²

b² - 4b + 24 = 0

b = 2 + 4.472i and 2 - 4.472i.

The standard form of 7 x 1 + 3 x ( 1/10 ) + 4 x ( 1 / 1000 ) is 0.7304 x [tex]10^{1}[/tex].

Given,

7 x 1 + 3 x ( 1/10 ) + 4 x ( 1 / 1000 )

We need to write this large number in standard form.

A standard form is a way of expressing a large number as a decimal number between 0 and 1 (including 1) and multiplied by a power of 10.

We have,

7 x 1 + 3 x ( 1 / 10 ) + 4 x ( 1 / 1000 )

7 + 0.3 + 0.004

7.304

Since we need a decimal point between 0 and 1.

We will multiply 7.304 by 10 / 10.

so we have,

7.304 x 10 / 10

(7.304 / 10 ) x 10

0.7304 x 10

Remember that a number to the power 1 is the number itself.

[tex]10^{1} = 10[/tex]

We see that in 0.7304 x [tex]10^{1}[/tex],

0.7304 is a decimal point between o and 1 and we have a power of 10.

It satisfies the standard form of a number.

Thus the standard form of 7 x 1 + 3 x ( 1/10 ) + 4 x ( 1 / 1000 ) is
