Which letters from the table represent like terms? -2x 3 4x 1

the men can be arranges in 5! ways

 and the women in 5! ways

so (5*4*3*2) = 120

120 *120 = 14,400 ways

To solve the given system of equations using substitution, we'll start by solving the first equation for x in terms of y. We'll substitute this expression for x in the other two equations to find the values of y and z.

To solve the given system of equations using substitution, we'll start by solving the first equation for x in terms of y: x = -2y + 10. We'll substitute this expression for x in the other two equations to find the values of y and z. Substituting -2y + 10 for x in the second equation, we have -6y = 6(-2y + 10) - 6.

Simplifying this equation, we get y = -2. Substituting y = -2 in the first equation, we find x = -2*(-2) + 10 = 14. Finally, substituting x = 14 and y = -2 in the third equation, we find z = -3*14 + 10*(-2) = -52.

The woman should have paid \$64 for the regular price of the merchandise.

To find out what the woman should have paid for the regular price, we need to reverse engineer the discount. Here's the step-by-step calculation:

Calculate the Discount Amount: Since the sale is 1/4 off, the discount is 1/4 of the regular price. So, the discount is:

[tex]\[ \frac{1}{4} \times \text{Regular Price} \][/tex]

[tex]\[ \text{Discount} = \frac{1}{4} \times \text{Regular Price} \][/tex]

Subtract the Discount from the Regular Price to Get the Sale Price: The sale price is the regular price minus the discount:

[tex]\[ \text{Sale Price} = \text{Regular Price} - \text{Discount} \][/tex]

Calculate the Sale Price: We know the woman bought $48 worth of merchandise at the sale price, so:

[tex]\[ \text{Sale Price} = \$48 \][/tex]

Find the Regular Price: Now we can set up an equation using the information we have:

[tex]\[ \$48 = \text{Regular Price} - \text{Discount} \][/tex]

Substituting the discount calculated earlier:

[tex]\[ \$48 = \text{Regular Price} - \left(\frac{1}{4} \times \text{Regular Price}\right) \][/tex]

Solve for the Regular Price:

[tex]\[ \$48 = \left(\frac{4}{4}\right) \times \text{Regular Price} - \left(\frac{1}{4}\right) \times \text{Regular Price} \][/tex]

[tex]\[ \$48 = \left(\frac{3}{4}\right) \times \text{Regular Price} \][/tex]

To isolate the regular price, multiply both sides by [tex]\( \frac{4}{3} \)[/tex]:

[tex]\[ \text{Regular Price} = \$48 \times \frac{4}{3} \][/tex]

[tex]\[ \text{Regular Price} = \$64 \][/tex]

So, the woman should have paid $64 for the regular price of the merchandise.

Complete Question:

The dress store is having a sale where all merchandise is 1/4 off a woman buys $48 of merchandise at the sale price what should she have paid for the regular price

Answer:

18.2

Step-by-step explanation:

Answer:

The correct option is 3.

Step-by-step explanation:

If a straight line passes through some of the points, none of the points, or all of the points of a scatter plot and best represents the data, then it is called a best fit line.

Best fit line minimizes the squared distance of each point. Some points of the scatter plot lie above and below the best fit line.

When determining slope, data points do not usually fall within a straight line, so you need to draw a best fit line, with as many points above and below the line as possible.

Therefore the correct option is 3.

Answer:29.15475947 (not rounded)

Step-by-step explanation:

663/3 = 21

21 is the middle number,

21+1 = 22

21-1 = 20

20 + 21 + 22 = 63

Our three consecutive integers can be represented as

X → first integer

X + 1 → second integer

X + 2 → third integer

If the sum of our three consecutive integers is 63, our equation will read...

X + X + 1 + X + 2 = 63

Now, we can simplify on the left. Once we simplify, our equation will now read

3x + 3 = 63

      -3    -3  ← subtract 3 on both sides

  3x = 60 ← divide both sides by 3

   X = 20

Our three consecutive integers can be represented as

X → first integer = 20

X + 1 → second integer = 21

X + 2 → third integer = 22

Therefore, the three consecutive integers are 20, 21, and 22.

Answer:

(x+3)(x-8)

Step-by-step explanation:

The sum of the geometric series is approximately 324.

The sum of a geometric series can be found using the formula:

Sn = a1(1 - rn) / (1 - r)

Where Sn is the sum of the series, a1 is the first term, r is the common ratio, and n is the number of terms.

Plugging in the given values, we have:

Sn = 4(1 - 3n) / (1 - 3)

Now we can solve for n by plugging in the given value of an:

324 = 4(1 - 3n) / (1 - 3)

Cross-multiplying and simplifying:

324(1 - 3) = 4(1 - 3n)

324 - 972 = 4 - 12n

-648 = -8n

Dividing both sides by -8, we get:

81 = 2n

Taking the logarithm base 2 of both sides:

n = log2(81)

Using a calculator, we find that n is approximately 6.3398.

Now we can plug this value back into the formula:

Sn = 4(1 - 36.3398) / (1 - 3)

Simplifying further:

Sn ≈ -648 / -2

Sn ≈  324

Answer:

18.5 meters

Step-by-step explanation:

As the maximum height ona projectile motion that starts from the ground and finishes at the ground is simmetric, the maximum height of the projectile will be found exactly at half of the distance tranveled horizontally, so the exact half of the total distance traveled horizontally is 18.5 meters, since distance is 37 meters and divided by 2 is 18.5.

The ball will travel 18.5 meters to reach its maximum height.
