Answer:

8 lb for $18.80 is best buy option

Step-by-step explanation:

Given:

Find:

Best buy option

Computation:

1.  2 lb for $4.98

For 1 lb = $4.98 / 2

For 1 lb = $2.49

2.  5 lb for $12.25

For 1 lb = $12.25 / 5

For 1 lb = $2.45

3.  8 lb for $18.80

For 1 lb = $18.80 / 8

For 1 lb = $2.35

Answer:

I think it's a 67.667

Step-by-step explanation:

1.Multiply each grade by the credits or weight attached to it

2. add all of the weighted grades together (or just the grades if there's no weighting)

3. divide the sum by the number of grades you added together

[tex]\boxed{\pink{\sf\leadsto Value \ of \ x \ is \ 24^{\circ}}}[/tex]

In the given parallelogram we can see that , <B is 5x° and <C is equal to 2x + 12°.

And these two are co - interior angles . And sum of co - interior angles is 180°.

Hence , here

[tex]\tt:\implies \angle DCB + \angle ABC = 180^{\circ} \\\\\tt:\implies (2x + 12)^{\circ} + 5x^{\circ}=180^{\circ} \\\\\tt:\implies 7x = (180 - 12 )^{\circ} \\\\\tt:\implies 7x = 168^{\circ} \\\\\tt:\implies x =\dfrac{168^{\circ}}{7} \\\\\underline{\boxed{\red{\tt\longmapsto x = 24^{\circ}}}}[/tex]

2:6

3:9

5:15

Step-by-step explanation:

Ask yourself: What times 3 equals my number?

As you can see 1x3=3 then 2x3=6, 3x3=9, and lastly 5x3=15

This is how you solve the chart.

Answer:21

Step-by-step explanation:

Answer:

y = 3

Step-by-step explanation:

9 - y = 2y

Step 1:  Add y to both sides

9 - y + y = 2y + y

9 = 3y

Step 2:  Divide both sides by 3

9 / 3 = 3y / 3

3 = y

Answer:  y = 3

Order of operation

Answer:

Step-by-step explanation:

Those angles are vertical angles, so their measure are equal, so we can set them equal to each other to solve this problem.

5x - 8  =  3x + 16

2x - 8  =  16

2x  =  24

y=-1/3

Answer and step-by-step explanation:

Checking what you've done, the first two images you've shown have the correct matching. But the last two are wrong. Reason being:

For the third mage, the table suggests that all the points are on the positive part of the y-axis, this means the curve should open upwards not downwards.

For the last image, the table suggests that the points are on the negative part of the y–axis except (0, 1). This means the curve should open downwards not upwards.

The table in the third image should match the graph in the last image and the table in the last image should match the graph in the third image.

Answer:

Step-by-step explanation:

GIVE ME THE BRAINLEST POINTS NOW

Answer:

x = 120

Step-by-step explanation:

All three angles are marked as equal. There are two ways to find x.

Method one

Find the supplement to x

Let the supplement to x be y

y + y + y = 180

3y = 180                 Divide by 3

y = 180/3

y = 60

=================

A straight line has an angle of 180 degrees.

x + y = 180             Substitute y = 60 into the equation

x + 60 = 180          Subtract 60

x = 180 - 60

x = 120

Method 2

The two angles not connect to x are called remote interior angles. These two angles are equal to x.

x = 60 + 60

x = 120

Answer:

A difference of squares has the following form . Any two perfect squares connected by subtraction can be factored.

It factors to (a+b)(a-b).

Step-by-step explanation:

A binomial is an expression with only terms where at least one is a term with a variable. When we can factor for difference of squares, we can have two variable terms or just one with a constant.

A difference of squares has the following form . Any two perfect squares connected by subtraction can be factored.

It factors to (a+b)(a-b).

Answer:

-3, -2, 2, 3

Step-by-step explanation:

It is the only choice that contains whole number.

Answer:

a) $26

b) 24.07%

c) $94.3

Step-by-step explanation:

Given that:

Before tax:

Normal price of dress = $62

Discounted price of dress = $48

Normal price of a pair of shoes = $46

Discounted price of a pair of shoes = $34

a) Before the sales tax, total savings = ($64 - $48) + ($46 - $34) = $26

b) Total percentage discount on total sales.

Total bill for original price = $62 + $46 = $108

Percentage discount can be found by the formula:

[tex]\dfrac{\text{Total discount}}{\text{Total bill for original price}}\times 100\\\Rightarrow \dfrac{26}{108} \times 100 = 24.07\%[/tex]

c) Total amount paid if the sales tax is 15%.

Amount paid with tax = Amount after discount + 15% of amount after discount

Amount after discount = $48 + $34 = $82

15% of $82 = $18.29

Amount paid with sales tax = $82 + $12.3 = $94.3
