Answer:

3x^2 + 3x - 7

Step-by-step explanation:

Given:

(6x^2 – 4x – 5 ) – (3x^2 – 7x + 2)

The correct way of subtracting the polynomial is by changing the sign of each term of the second polynomial. Like this

= 6x^2 – 4x – 5 – 3x^2 + 7x - 2

Collect like terms

= 6x^2 - 3x^2 - 4x + 7x - 5 - 2

Simplify

= 3x^2 + 3x - 7

(6x^2 – 4x – 5 ) – (3x^2 – 7x + 2) = 3x^2 + 3x - 7

From the answer, the coefficient of x^2 is 3, coefficient of x is 3

Step-by-step explanation:

Answer:

33h

Step-by-step explanation:

first you distribute the three:    3 x 5 + 3 x 6h

then you multiply:    3 x 5 = 15   3 x 6h = 18h

then you add:    15 + 18h = 33h

                           (just add 15 and 18 then add h on the end)  

Answer:

Length of route that passes the mall= 11 miles

Length of route that passes the theater= 13 miles

Step-by-step explanation:

route to school that passes the mall (highlighted in red)

= (x +1) +(x +2)

= 2x +3

route to school that passes the theater (in yellow)

= (2x +1) +x

= 3x +1

Since the first is 2 miles shorter,

2x +3= 3x +1 -2

Simplify:

2x +3= 3x -1

Bring constants to 1 side, x terms to the other:

3x -2x= 3 +1

x= 4

Substitute x=4 to find the length of each route:

Length of the route that passes the mall

= 2x +3

= 2(4) +3

= 8 +3

= 11 miles

Length of route that passes the theater

= 3x +1

= 3(4) +1

= 12 +1

= 13 miles

Alternatively, length of route that passes the theater

= 11 +2= 13 miles since it is 2 miles longer than that which passes the mall.

Answer:

[tex]Weight = \frac{23}{2}[/tex]

Step-by-step explanation:

Given

Weight of Pinata = 11/4 lb

Weight of candies = 3/8, 3/8, 1/2 , 1/2, 1/2, 3/4, 3, 11/4

Required

Weight of Pinata when filled with candies

To solve this question, we simply need to add all weights together

First, we need to add up the weight of the candies

[tex]Candies = \frac{3}{8} + \frac{3}{8} + \frac{1}{2}+ \frac{1}{2}+ \frac{1}{2}+ \frac{3}{4} + 3 + \frac{11}{4}[/tex]

Take LCM

[tex]Candies = \frac{3 + 3 + 4 +4 + 4 + 6 + 24 + 22}{8}[/tex]

[tex]Candies = \frac{70}{8}[/tex]

Simplify:

[tex]Candies = \frac{35}{4}[/tex]

Next; Add the weight of the candies to the weight of pinata

[tex]Weight = Candies + Pinata[/tex]

[tex]Weight = \frac{35}{4} + \frac{11}{4}[/tex]

Take LCM

[tex]Weight = \frac{35 + 11}{4}[/tex]

[tex]Weight = \frac{46}{4}[/tex]

Simplify

[tex]Weight = \frac{23}{2}[/tex]

Hence, the weight of the Pinata after it is filled with candies is 23/2 lb

Answer: The ratio of candy to fruit in a pinatas is 1/2 pound to 3/4. if we fill two pinatas and use 4 pounds of candy. how many pounds of will we need? Explain?

The width of the rectangular base of the pyramid is W = 3 centimeters

The volume of a pyramid, is the product of the area of its base with the height of the pyramid, and divide by 3. We express this product with the formula V = ( 1/3) ×B×h, where B is the area of the base of the pyramid, and h is its height.

Volume of Pyramid = ( 1/3 )a²H

Given data ,

Let the volume of the pyramid be represented as V

Now , the value of V is

V = 105 cm³

And , the length of the pyramid L = 7 cm

The height of the pyramid is H = 15 cm

Let the width of the pyramid be W

And , Volume of Pyramid = ( 1/3 ) ( L x W x H )

105 = ( 1/3 ) ( W x 15 x 7 )

On simplifying , we get

105 ( W ) ( 1/3 ) = 105

Divide by 105 on both sides , we get

W / 3 = 1

Multiply by 3 on both sides , we get

W = 3 cm

Therefore , the value of W is 3 cm

Hence , the width of pyramid is 3 cm

Answer:

k = 10

Step-by-step explanation:

∡ZYX = 180° - 115° = 65° (angles in a line add up to 180°)

*∡ stands for angle.

∑ of  ∡Z , Y and X should be equal to 180° (angles in a triangle add up to 180°)

∴ (4k + 5)° + 65° + (6k + 10)° = 180°

10k + 80 = 180

10k = 100

k = 100 ÷ 10 = 10

Answer:

Greater than

Step-by-step explanation:

First, I solved the expressions.

3(4x-1)=12x-3

2(4-x)=8-2x

12x-3>8-2x

As we can see, 12x-3 is greater than 8-2x.

Step-by-step explanation:

12x - 3 (expand 3(4x-1))

8-2x (expand 2(4-x))

if you assume that x=1 then 12x-3 would be 12(1)-3 then it would be 9 for the first

for the second equation, 8-2x, it would be 8- 2(1) or 6

9>6 so, 3(4x-1) > 2(4-x)

(-13, -12)

Step-by-step explanation:

The midpoint (x,y) between two points ([tex]x_1,y_1[/tex]) and ([tex]x_2,y_2[/tex]) on the coordinate plane is given by:

[tex]x=\frac{x_1+x_2}{2};\\\\y=\frac{y_1+y_2}{2}[/tex]

Hence given that house A is at (3, 6) and house B is at (-5, -3). Since house B is placed at the middle of house A and house B, let the coordinates of house C be ([tex]x_2,y_2[/tex]). Hence:

[tex]-5=\frac{3+x_2}{2\\} \\3+x_2=-10\\\\x_2=-10-3\\\\x_2=-13[/tex]

[tex]-3=\frac{6+y_2}{2\\} \\6+y_2=-6\\\\y_2=-6-6\\\\y_2=-12[/tex]

Therefore house C is at (-13, -12)

Answer:

yes

Step-by-step explanation:

Both of the figures have the same perimeter (4n + 4) hence equal in perimeter,

We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.

We know the perimeter of a rectangle is 2(length + width) and the perimeter of a square is 4×side.

Given, A rectangle with sides of length n+2 and n.

∴ Perimeter = 2((n + 2) + n)

= 2(2n + 2).

= 4n + 4.

Also given, A square with sides of length n + 1.

∴ Perimeter = 4(n + 1).

= 4n + 4.

So, yes the two shapes are equal in the perimeter.

Answer:

Amount of NaCl = 23.376 gram

Step-by-step explanation:

Given:

Molarity = 4M

Volume of solution = 100 ml

Find:

Amount of NaCl

Computation:

Molar mass of Na = 22.99 g/mole

Molar mass of Cl = 35.45 g/mole

Molar mass of NaCl =  22.99 + 35.45

Molar mass of NaCl  = 58.44 g/mole

Molarity = [moles of solute / volume of solute(ml)]1,000

4 = [moles of solute / 100]1000

Moles of solute = 0.4

moles of solute = Mass of solute / molar mass

0.4 = Amount of NaCl / 58.44

Amount of NaCl = 23.376 gram

If you're trying to find the whole number from a percentage of the number, divide the number by its percent: 1360/17%= 8000. The total number of mangoes is 8000.

Step-by-step explanation:

Answer:

[tex]\boxed{\bold{\huge{\boxed{\sf x = 8000 \ mangoes}}}}[/tex]

Step-by-step explanation:

Let the number be x

The given condition is:

=> 17 % of x = 1360

=> [tex]\sf \frac{17}{100} * x = 1360[/tex]

Multiplying both sides by [tex]\frac{100}{17}[/tex]

=> [tex]\sf x = \frac{136000}{17}[/tex]

=> x = 8000

So, total number of mangoes is 8000.

Step-by-step explanation:

Since only 48 bears can be fitted into 1 carton, we need to find how many cartons approximately 500 bears can fit in:

500/48 = 10.4167 cartons

We can't have 4/10ths of a carton. Makes no sense in the real world. Therefore, we need a total of 11 cartons to pack 500 bears, even if one box isn't full.
