Step-by-step explanation:

Answer:

Algebraic expression for three times the sum of a and b, then the expression would be; 3(a+b).

Simplification involves proceeding with the pending operations in the expression. Like, 5 + 2 is an expression whose simplified form can be obtained by doing the pending addition, which results in 7 as its simplified form. Simplification usually involves making the expression simple and easy to use later.

Answer:

20 - 2n

Step-by-step explanation:

The sequence is arithmetic since the difference between consecutive terms is constant, that is

d = 16 - 18 = 14 - 16 = 12 - 14 = - 2

The n th term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

here a₁ = 18 and d = - 2, thus

[tex]a_{n}[/tex] = 18 - 2(n - 1) = 18 - 2n + 2 = 20 - 2n

[tex]a_{n}[/tex] = 20 - 2n

If we know that [tex]x_{1} = 18[/tex] and [tex]r = -2[/tex], then the n-th term of the number sequence is [tex]f(n) = 18 -2\cdot (n-1)[/tex].

This sequence is an example of an arithmetic sequence, since each consecutive pair of elements has one and only one difference, that is to say:

[tex]r = x_{i+1}-x_{i}[/tex], [tex]\forall\,i\in \mathbb{N}[/tex] (1)

The expression for any arithmetic sequence is described by the following formula:

[tex]f(n) = x_{1} + r\cdot (n-1)[/tex], [tex]n \ge 1[/tex] (2)

Where:

If we know that [tex]x_{1} = 18[/tex] and [tex]r = -2[/tex], then the n-th term of the number sequence is [tex]f(n) = 18 -2\cdot (n-1)[/tex].

Step-by-step explanation:

To determine the football team's change in field position using a number line, one would sequentially move 5 units left for each loss of 5 yards over 3 plays, resulting in a total change of -15 yards.

To find the football team's change in field position after the 3 plays, you can use a number line to represent the yards on the field.

If we consider the team's starting point as zero on the number line, each loss of 5 yards will be represented as moving 5 units to the left (into the negative side) from that starting point. Here's how you would calculate it step by step:

Mark the starting point at zero on the number line.

Since the team lost 5 yards on the first play, move 5 units to the left and mark that new point, which represents -5 yards.

Repeat the process for the second play, moving another 5 units to the left from the -5 mark to reach -10 yards.

Finally, for the third play, move yet another 5 units to the left to end up at -15 yards.

Therefore, after 3 plays with each losing 5 yards, the team's field position has changed by -15 yards.

Answer:

6i[tex]\sqrt{21}[/tex]

Step-by-step explanation:

Note that [tex]\sqrt{-1}[/tex] = i

Using the rule of radicals

[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]

Simplifying the radical, that is

[tex]\sqrt{-84}[/tex]

= [tex]\sqrt{4(21)(-1)}[/tex]

= [tex]\sqrt{4}[/tex] × [tex]\sqrt{21}[/tex] × [tex]\sqrt{-1}[/tex]

= 2 × [tex]\sqrt{21}[/tex] × i

= 2i[tex]\sqrt{21}[/tex]

Hence

3[tex]\sqrt{-84}[/tex]

Answer:

42

Step-by-step explanation:

if you divide 546 with 13 it will give you 42 mostly because 546 is the total of miles that he drove so if you dive by how many days he has been driving you will get your answer.

Troy drove 546 miles over 13 days, resulting in an average of 42 miles driven each day after dividing the total miles by the number of days.

To find out how many miles Troy drove each day, we need to divide the total number of miles driven by the number of days. Troy drove a total of 546 miles over the course of 13 days.

Divide the total miles (546) by the number of days (13).

The calculation is:

546 miles / 13 days = 42 miles per day.

Therefore, Troy drove 42 miles each day.

Option C

Answer: multiplication and addition

Step-by-step explanation:

In mathematics we use addition(+) operation to show "sum", subtraction (-) to show "difference" , multiplication (×) operation to show "product" and divide (÷) to show "quotient".

Given mathematical statement : eight more than the product of a number and two

Here, we use addition(+) operation to show "more than" and multiplication (×) operation to show "product" .

Answer:

Step-by-step explanation:

a^2 + b^2 = c^2

12^2 + b^2 = 13^2

144 + b^2 = 169

b^2 = 25

b = 5

Jeremiah should start his cut 5 inches from P.

In the figure PQRS,

QR= 12 in. & PS = 13 in.

∠Q=∠R=90°

Now, Jeremiah will make exactly one straight cut from the top edge of the cardboard to point S in order to cut the cardboard into a rectangle.

Let, Jeremiah cut PQ at point M, where SM⊥PQ

∴ ∠SMP = 90°, so ΔSMP is a right angle triangle.

After draw SM, SMQR will a rectangle.

Then, SM = QR = 12 in.

By pythagoras theorem,

PS²= SM²+PM²

⇒ PM²= PS²-SM²

⇒ PM²= 13²-12²

⇒ PM²= 169-144

⇒ PM = √ (25)

⇒ PM = 5   (Negative value is not possible)

So, PM = 5 inches

Answer:

X=18

Step-by-step explanation:

Multiply the 6 and the 15= 90

Then left with 5x so then divide 90 and 5= 18

Left with X= 18

The value of x in the given equation is x = 18.

Given is an equation 5x/6 = 15, we need to find the value of x,

To solve for x, you need to isolate x on one side of the equation.

Here's how you can do it step by step:

Start with the equation: 5/6 x = 15

To isolate x, you need to get rid of the fraction on the left side. Since the fraction has a denominator of 6, you can multiply both sides of the equation by 6 to eliminate it:

(6) × (5/6 x) = (6) × 15

The 6 on the left side cancels out the denominator 6, leaving:

5x = 90

Now, to find the value of x, you need to get x by itself on one side. Since 5x means 5 times x, you can undo this by dividing both sides by 5:

5x / 5 = 90 / 5

This simplifies to:

x = 18

So, the value of x is 18.
