Which symbol goes in the box to make the comparison true?

Answers

Answer:

what box?

Step-by-step explanation:

if the box is between 5 and 7 then you multiply 16 by 5 which is 80. then multiply 7 by 16 which is 112. since 80 is smaller than 112, the symbol is < so the answer is: 80<112 or 16x5 < 7x16

Answer:

990, C

Step-by-step explanation:

The formula for the surface area of the bottom cushion is

A = 2wl + 2lh + 2hw (w is width, l is length, h is height)

w = 18, l = 21, h = 3

A = 2(18)(21) + 2(21)(3) + 2(3)(18)

A = 2(378) + 2(63) + 2(54)

A = 756 + 126 + 108

A = 990 (C)

Deb would have made $18 from selling 14 cups of lemonade. She earned $20 for selling 10 which is $2 per cup. Add $2 dollars for 4 more cups which makes $18
Deb earned 20 dollars from 10 cups of lemonade so 2$ per cup
She sells 4 more so 8 more dollars.
20+8=28
Deb made 28$ in all

Answers

Answer:

I think it's "d=19"

D would equal 19. First, you combine like terms, so add -1 and 105 together to get 104. Then you have to subtract 104 from both sides. After that you get 76 on the right side. Then you would have to divide 4 from both sides to get d by itself. Lastly, 76 divided by 4 is 19.

Values of the elements in the Matrix are A₂₁ = -2, A₂₂ = 0, A₂₃ = 4, A₃₃ = 5.

What is the matrix?

A collection of numbers lined up in rows and columns to form a rectangular array is called a matrix. The elements, or entries, of the matrix, are the integers. In addition to many other areas of mathematics, matrices have numerous applications in the fields of engineering, physics, economics, and statistics.

given, the sum of each row is equal to the sum of each column equals the sum of all diagonals.

Since, the sum of column C₁ = 3 + -2 + 1 = 2

the sum of Row R₁ = 3 + A₂₁ + 1 = 4 + A₂₁

Since this is equal to the sum of column C₁

thus, 4 + A₂₁ = 2

A₂₁ = -2

the sum of column C₂ = A₂₁ + A₂₂ + 4

C₂ = -2 + A₂₂ + 4

C₂ = A₂₂ + 2

Since this is equal to the sum of column C₁

2 = A₂₂ + 2

A₂₂ = 0

the sum of Row R₂ = -2 + A₂₂ + A₂₃

R₂ = -2 + 0 + A₂₃

Since this is equal to the sum of column C₁

2 = -2 + A₂₃

A₂₃ = 4

the sum of Row R₃ = -1 + 4 + A₃₃

R₃ = -3 + A₃₃

Since this is equal to the sum of column C₁

2 = -3 + A₃₃

A₃₃ = 5

therefore, the values of the matrix's elements are A₂₁ = -2, A₂₂ = 0, A₂₃ = 4, A₃₃ = 5.

Solve for Variable: 3x + 7 < 16
A. x > 3
B. x < 5
C. x > 6
D. x < 3

Answers

Answer:

D. x < 3

Step-by-step explanation:

3x + 7 < 16

To solve, we have to isolate x.

3x + 7 < 16

Subtract 7 from both sides :

3x < 9

Divide 3 from both sides :

x < 3

Now in some cases, you could say that the inequality sign would switch, but this is only when you divide by a negative sign, so keep that in mind.

3x+2x+80=180

5x=100
ANSWER IS x=20

So to check if the answer is correct:
Angle 3x is 3x20 = 60 degrees
Angle 2x is 2x20= 40degreee

60+40+80= 180 degrees
Well, the base of it is a 180° angle and the middle angle is 80°. That leaves 3x and 2x.

3 x 20 = 60
2 x 20 = 40
60 + 40 = 100
100 + 80 = 180
180°
