Karen and Kevin collect coins. Karen has x coins. Kevin has 5 coins fewer than two times the number of coins Karen has. Write and simplify an expression for the total number of coins Karen and Kevin have.

Step-by-step explanation:

subtract 12:56 from 8:01 to get 4:55. That’s 4 hours and 55 minutes

thats in hours! if it was minutes it would be 4 minutes and 55 seconds

Answer:

264 in²

Step-by-step explanation:

the surface area of the ramp = 2 x ½ x 6 x 8 + 9 x 10 + 8 x 9 + 6 x 9

                                                = 48 + 90 + 72 + 54

                                                = 264 in² (simple calculation)

Answer:

y=5

Step-by-step explanation:

divide both sides of the equation by 8.

8/8=1

40/8=5

Therefore

1y=5 or y=5

Answer:  A+4b = 360

4b = weight of 4 bricks, which is added to Adam's weight (A) to get a total of 360 pounds.

Answer:

(x-3)(x+3)(x+2)

Step-by-step explanation:

x^3 + 2x^2 - 9x -18

= x^2(x+2) - 9(x+2)

= (x^2 - 9) (x+2)

= (x+3)(x-3)(x+2)

hope this helps:))))))

if theres 2 and 15, its just 2 of that to 15 of the other

its 2:15 or 2/15 or whatever way you want to write a ratio

fun fact:

The Hog Rider card is unlocked from the Spell Valley (Arena 5). He is a quick building-targeting, melee troop with moderately high hitpoints and damage. He appears just like his Clash of Clans counterpart; a man with brown eyebrows, a beard, a mohawk, and a golden body piercing in his left ear who is riding a hog. A Hog Rider card costs 4 Elixir to deploy.

Answer:

12) x= 29 ; (4+5x) = 149° ; (x+2) = 31°

15) x=29 ; (2x+1) = 59° ; (x+2) = 31°

16) x=17 ; (4+2x) = 38° ; (3x+1) = 52°

Step-by-step explanation:

So for each problem you follow the same steps.

1) See what the angles should measure up to. (#12 is 180°, and #15 & 16 is      90°

2) Write your equation. (I'm going to use #12 as an example). 4+5x+x+2=180

3) Simplify the equation. 6x+6=180

4) Solve the equation. x=29

5) Then replace each x with the 29, and solve.

6) To double-check the angles, add both angles together and they should be 180° (or whatever you decided you were solving for on step 1)

Answer:

132cm^2

Step-by-step explanation:

First find the area of the rectangle above the trapezoid using the formula LW

7(4)

28

Then find the formula of the trapezoid using the formula 1/2h(b1+b2)

1/2×8(7+19)

4(26)

104

Finally add both the areas to find your total area

104+28=132cm^2

Answer:

7

Step-by-step explanation:

Answer: Length is 6 ft and

Width is 1 ft

Step-by-step explanation: The first clue we have been given is that the width of the rectangular fence is five feet less than it's length. So, if the length is L, the width is L - 5. From that bit of information on we can calculate the area if he rectangular fence as

Area = L x W

Area = L x (L - 5)

Area = L² - 5L

Also, the question further states that if the length is decreased by three feet (L = L - 3), and the width is increased by one foot (W = {L - 5} + 1 and that becomes L - 4), the area of the new enclosure would be the same as the first one. The area of the new enclosure would be given as

Area = L x W

Area = (L - 3) (L - 4)

Area = L² - 4L - 3L + 12

Area = L² - 7L + 12

Since the question states that the area of the original fence and the new one are the same, we can now write the following expression

L² - 5L = L² - 7L + 12

(That is, area of the first set of dimensions equals area of the second set of dimensions)

L² - 5L = L² - 7L + 12

By collecting like terms we now have

L² - L² - 5L + 7L = 12

(Note that when a positive value crosses the equation to the other side, it becomes negative and vice versa)

2L = 12

Divide both sides of the equation by 2

L = 6

Having calculated the length of the rectangular fence as 6 ft, the width is now derived as

W = L - 5

W = 6 - 5

W= 1

Therefore, the length is 6 ft and the width is 1 ft.

Answer:

They need $910 in total for all the supplies but they only have $890.20, so no they don’t have enough.

Step-by-step explanation:

30 pieces of plywood x $25.00 per ply wood = 30 x 25= 750

20 packs of bricks x $2 per brick= 20 x 2= 40

6 pack of screws x $20 per pack = 6 x 20= 120 

750 + 40 + 120= 910

Answer:

14 just look at the gallons chart, one gigantic G with four pints , and in every pint is two cups, so get rid of one pint and count the remaining cups.

1 gallon = 4 quarts = 8 pints = 16 cups = 128 fluid ounces

Nicco+Andrew = 1 + 1 = 2 pints

remaining juice = 8 pints(1 gallon) - 2 pints = 6 pints

Answer:

The difference between the volume of the prism and the volume of the storage container is 35 - 31.25 = 3.75 cm³      

Step-by-step explanation:

Given : A rectangular prism has a length of  cm, a width of  cm, and a height of 5 cm.

Justin has a storage container for the prism that has a volume of 35 cm³.

We have to find the difference between the volume of the prism and the volume of the storage container.

Since  the volume of the rectangular prism is given as the product of its length , width and height.

Mathematically written as,

Volume of rectangular prism = Length ×  Width ×  height

Given - length =   cm,

width =  cm,

and  height = 5 cm.

Thus, Volume of rectangular prism =

Simplify, we have,

Thus, Volume of rectangular prism =  cm³

Thus,  the difference between the volume of the prism and the volume of the storage container is 35 - 31.25 = 3.75 cm³

Answer:

umm well can u give a pic of the chapter so we can give answer!?

Solution:

It should be noted:

Square root both sides of the equation to find the length of the square garden. Then, use the length of the square garden to calculate the length of fence required for 3 sides of the garden.

Square root both sides.

Multiply the length by 3.

Thus, Mr. Campbell will need 48 feet of fencing.

Answer: 1   2/5

Step-by-step explanation:

8 2/5 ÷ 6

Convert 8 2/5 to an improper fraction

42/5

Find the reciprocal of 6 (turn it upsidedown)

42/5 x 1/6

42/30

1 12/30

Reduce

12/30= 2/5

[MA]:

7/5

The explanation:

[tex]\frac{42}{5}[/tex] ÷ [tex]\frac{6}{1}[/tex]

42 x 1 = 42

5 x 6 =  30

42/30 = simplifying = 1 2/5

1 2/5 = simplifying = 7/5

mixed number in simplest: 7/5

Answer:

9. 80% 10. 150%

Step-by-step explanation:

9. 20 x 4 = 80/ 20 x 5 = 100

80/100 = 80%

10. 6 x 25 = 150/ 4 x 25 = 100

150/100 = 150%

Answer:

It is 2/4 equal to 1/2 (2.5)

Answer:

23/9

Step-by-step explanation:

Explanation:

We first let 2.5 (5 being repeated) be x

Since x is recurring in 1 decimal places, we multiply it by 10.

10x = 25.5

Next, we subtract them.

10 x - x = 25.5 - 2.5

9x = 23

Lastly, we divide both sides by 9 to get x

as a fraction.

x =23/9
