The required expression will therefore be:

(3×18) + (5×6) + 4

Her total score is 88points :

From the question given, we are told that Samantha scored 3 points for each of 18 multiple choice questions, this means that the total points made here is expressed as:

(3 × 18) ...1

If she got 5 points for each of the 6 short response questions she answered

correctly, the total point made will be expressed as;

(5×6) ... 2

Total score for an additional 4 points for the bonus question will be "4"

Expression for her total score will be the sum of all the expression above as thus:

(3×18) + (5×6) + 4

Taking the sum, her score will be:

= (3×18) + (5×6) + 4

= 54 + 30 + 4

= 84 + 4

= 88 points

The required expression will therefore be:

(3×18) + (5×6) + 4

Her total score is 88points

Answer:

as both triangles are congruent......

AB = PQ

BC = QR

CA = RP

So AB = PA so... 2x + 1 = x + 7

so x = 7 - 1 = 6

now BC = QR so.... 4y + 3 = 2y + 11

so 2y= 8 and y= 4

Answer:

416 g

Step-by-step explanation:

The mean is calculated as

mean = [tex]\frac{sum}{count}[/tex] , then

[tex]\frac{sum}{5}[/tex] = 398 ( multiply both sides by 5 )

sum of 5 pods = 1990 g

let x be the weight of the sixth pod , then

[tex]\frac{1990+x}{6}[/tex] = 401 ( multiply both sides by 6 )

1990 + x = 2406 ( subtract 1990 from both sides )

x = 416

That is the weight of the sixth pod is 416 g

Answer:

x= -2   and x = 6

Step-by-step explanation:

The solutions are where the two graphs intersect

x=6, y= 10  is one point

x=-2 and y = -6 is the other point

The intersection points of both the equations are the solutions

From the graph the points are

Hence

x=-2 and x=6 are the solutions

Option D

Answer:

[tex]ML = 76\text{ feet}[/tex]

Step-by-step explanation:

Since Line LR bisects MN at point L, by the definition of bisector:

[tex]\overline{ML} \cong \overline{LN}[/tex]

We want to determine ML if MN measures 152 feet.

MN is the sum of ML and LN. Hence;

[tex]ML + LN = MN[/tex]

Since ML = LN and MN = 152:

[tex]ML + (ML) = (152)[/tex]

Simplify:

[tex]2ML = 152[/tex]

And divide. Therefore:

[tex]ML = 76\text{ feet}[/tex]

In conclusion, ML measures 76 feet.

Step-by-step explanation:

Mastercard cards – Begin with a 5 and has 16 digits. American Express cards – Begin with a 3, followed by a 4 or a 7 has 15 digits. Discover cards – Begin with a 6 and have 16 digits. Diners Club and Carte Blanche cards – Begin with a 3, followed by a 0, 6, or 8 and have 14 digits.

The valid mastercard number is D) 5424 1801 2345 6789​.

The steps to find valid card number are-

Step 1a. For a card number with an even number of digits (e.g., Visa or MasterCard), double alternating digits starting with the first digit in the sequence.

Step 1b. For a card with an odd number of digits (e.g., American Express), double alternating digits starting with the second digit in the sequence.

Step 2. If the doubling resulted in a number with two digits, add them together to get a single digit number

Step 3. Now go back to the original credit number and replace the digits that you doubled with the new value — either the doubled value, or the doubled value with the digits added together — and add it all up.

Step 4. Check to see if the sum is evenly divisible by 10 (you can simply look to see whether or not it ends with a zero).

Now the given options are

A) 4224 1801 2345 6781

B) 4224 1801 2345 6789

C) 5424 1801 2345 6781

D) 5424 1801 2345 6789​

Here we see that, the card number 5424 1801 2345 6789 is a master card since it is starting with 5 and Since there are sixteen digits, we’ll start by doubling the 1st, 3rd, etc. digits and then summing.

(1+0) + 4 + (4) + 4 + (2) + 8 + (0) + 1 + (4) + 3 + (8) + 5 + (1+2) + 7 + (1+6) + 9

This totals up to 70, which is evenly divisible by 10. In other words, this is a potentially valid mastercard number.

Thus, the valid mastercard number is D) 5424 1801 2345 6789​.

Answer:

Step-by-step explanation:

Using x and y to represent the 2 numbers with x > y , then

x + y = 15 → (1)

x - y = 11 → (2)

Adding the 2 equations term by term to eliminate y

2x = 26 ( divide both sides by 2 )

x = 13

Substitute x = 13 into (1)

13 + y = 15 ( subtract 13 from both sides )

y = 2

The 2 numbers are 13 and 2

Answer:

70 ft^2

Step-by-step explanation:

Find the area of the wall

A = l*w where l is the length and w is the width

A = 8 2/5 * 16 2/3

Change to improper fractions

A = 42/5 *50/3

  Rewriting

A = 42/3 * 50/5

    = 14 * 10

A = 140 ft^2

He paints 1/2

1/2 (140) = 70 ft^2

Answer:

First, just  to recap, the angle that has a measure of 60 and the angle that has a measure of 2x+14 are vertical angles.

This means, that they are equal to each other.

Knowing this, the rest is pretty easy. We just set up an equation:

60 = 2x+14

And solve for x: (I'm going to speed through, but let me know if you need me to go step by step...)

2x = 46
