2) Cereal cost $7 / box. How many boxes
did Huong buy if she spent $21?

Answer:

8a-b+1

Step-by-step explanation:

Difference means subtract

(8a + 2b - 4) - (3b - 5)

Distribute the minus sign

(8a + 2b - 4) - 3b + 5

Combine like terms

8a + 2b-3b - 4  + 5

8a-b+1

Answer:

Like terms means that the numbers have the same variable after them or they don't have a variable at all.  It is also important to remember that any letter that doesn't have a number in front of it technically has a 1 in front of it.

For example, x + 3x = 1x +3x.  Then I add the numbers in the front and I get 4x.

If it had been 4x + 7x + 3, my answer would have been 11x +3.  That's because there were a total of 11 x, but the 3 ones weren't x's so I just leave them alone.

Step-by-step explanation:

Answer:

[tex]8x[/tex]

Step-by-step explanation:

[tex]x+7x[/tex]

[tex]8x[/tex]

The answer is [tex]8x[/tex] when you simplify because you are adding another [tex]x[/tex] to [tex]7x[/tex] so it becomes [tex]8x[/tex]

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

Explanation:

There is a dime and 2 quarters in the bottom row.

So we have 10+25+25 = 60 cents in the bottom row.

Then in the top row, there's a penny and a nickel. So that's an extra 1+5 = 6 cents.

Overall, the total value is 60+6 = 66 cents

Note: 66 cents converts to $0.66 or you can say 0.66 dollars.

Step-by-step explanation:

The volume of a right square pyramid is given by the formula ...

  V = 1/3Bh

where B is the area of the base.

The volume of the larger pyramid will be ...

  V' = 1/3(5B)h

So, the ratio of volumes is ...

  V'/V = (1/3(5B)h)/(1/3Bh)

  V'/V = 5

The ratio of volumes is 5.

Answer:

6 2/3 = x

Step-by-step explanation:

24 1/14 + 8 3/7  = (x ÷ 1 1/9) * 5 5/12

Add on the left by getting a common denominator

24 1/14 + 8 3/7*2/2  = (x ÷ 1 1/9) * 5 5/12

24 1/14 + 8 6/14  = (x ÷ 1 1/9) * 5 5/12

32 7/14  = (x ÷ 1 1/9) * 5 5/12

32 1/2 =  (x ÷ 1 1/9) * 5 5/12

Changing to improper fractions

(2*32+1)/2 = (x ÷ 10/9) * (12*5+12)/12

65/2 = (x ÷ 10/9) * (65)/12

Multiply each side by 12/65

65/2 * 12/65 = (x ÷ 10/9) * (65)/12*12/65

6 = (x ÷ 10/9)

Copy dot flip

6 = x * 9/10

Multiply by 10 /9

6 * 10/9 = x * 9/10 * 10/9

60/9 =x

20/3 =x

Changing back to a mixed number

By using unitary method, Cost of 11 bags of chips is $6.6.

It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

Given

Christine has bought 6 bags of chips that she bought for $3.60.

Cost of 11 bags of chips = ?

6 Bags ⇒ $3.60

11 Bags ⇒ X

6X = 11 × 3.60

X = [tex]\frac{11(3.6)}{6}[/tex]

X = [tex]\frac{11(36)}{60}[/tex]

X = [tex]\frac{33}{5}[/tex]

X = 6.6

Thus, Cost of 11 bags of chips is $6.6.

Answer: ok fine

Step-by-step explanation:

Answer:

A. 6 B. 2 C. 1

Step-by-step explanation:

For A, we can count how many people are on the left said and in the middle, since David is in both clubs. For B, we can only count the right side because it says "...are in the math club BUT NOT IN THE SPANISH CLUB." For C, We can only count the middle, which is only David.

Answer:

A)6 B)2 C)1

Step-by-step explanation:

For A: There are 6 students because 5 are originally in the Spanish club, while 1 is in both clubs. This still means David is in the Spanish club so there are 6 students.

For B: There are 2 students because the condition is that, only students in the Math club are counted. In this scenario, David doesn't count because he is part of both clubs. So only Isabel and Carmen count, which means there are only 2 people.

For C: There is 1 student because the condition is that, only the students in both clubs count. The place where the two circles overlap will hold the student who is in both clubs. In that area, there is only David, making it so there is one 1 student.

Answer:

C-480

Step-by-step explanation:

You divide it into 3 shapes.

For example -

First shape 4*4*5=80

Second shape 5*4*8=160

Third shape=5*12*4=240

Then, add them together.

160+240+80=480

Answer:

{a , c}

Step-by-step explanation:

first find u intersection p

n(U n P ) = {a , b , c , d} n {b , d , e}

={d , b}

intersection means element or values which lies in both the sets

now to find p complement

note : p( bar at the top ) is read as p complement

p complement = n(U) - n(U n P)

={a , b , c , d} - {d , b}

={a , c}

n(U) -n(U n P) means the elements which is only in n(U ) but not in n(U n P)

Answer:

Volume = 66

Surface are = 144

Step-by-step explanation:

1. Volume

The formula to find the volume of a triangular prism is the following,

[tex]A=\frac{l*w*h}{2}[/tex]

The following information is given,

lenght = 4

width = 11

hieght = 3

Substitute these numbers into the formula and solve for the heihgt,

[tex]A=\frac{l*w*h}{2}\\\\A=\frac{4*11*3}{2}\\\\A=66[/tex]

2.Surface area

The surface area of a figure is the two-dimensional distance around the figure. It can be found by finding the area of each face of the figure and then adding the result up.

The formula to find the area of a rectangle is the following,

[tex]A_r=(lenght)(width)[/tex]

The formula to find the area of a triangle is the following,

[tex]A_t=\frac{(legnth)(width)}{2}[/tex]

Substitute in the give values and add up the results to find the total surface area of the rectangle,

[tex]((5)(11))+((4)(11))+((3)(11))+(\frac{(3)(4)}{2})+(\frac{(3)(4)}{2})\\\\=55 + 44 + 33+ 6 + 6\\\\= 144[/tex]

Answer:

1. 523 cm^3

2. 1.6 ft

Step-by-step explanation:

1. Formula for volume of a sphere is (4/3)(pi)(r^3)

r = 5

(4/3)(3.14)(5^3) ≈ 523

2. Formula for volume of a cone is (1/3)(pi)(r^2)(h)

(1/3)(3.14)(1^2)(2) ≈ 2.0933

Plug this into the formula for volume of a sphere and find r.

2.093 = (4/3)(3.14)(r^3)

r ≈ 0.7937

Multiply by 2 to get the diameter, which is the height of the spherical barrier.

r * 2 ≈ 1.6
