35 pounds of black tea is needed to be mixed to get the final mixture for 2.10 per pound

An equation is an expression that shows the relationship between two or more numbers and variables.

Let x represent the amount of black tea worth 1.80 per pound to be mixed to get the final mixture for 2.10 per pound, hence:

2.4(35) + 1.8(x) = 2.1(x + 35)

x = 35 pounds

35 pounds of black tea is needed to be mixed to get the final mixture for 2.10 per pound

Answer:15

Step-by-step explanation:

A ladder is resting against a wall.The top of the ladder touches the wall at a height of 9 feet.Find the length of the ladder if the length is 3 feet more than its distance from the wall.

Let the distance of the ladder from the wall be x

The length of the ladder = x+3

The ladder touches the wall at a vertical height of 9 feet.

(x+3)^2 = x^2 + 9^2 ( using the pythagoras theorem

x^2 + 6x+ 9 = x^2 + 81

x^2- x^2 +6x = 81-9

6x= 72

x= 12

Therefore the length of the ladder will be x+3 = 12 + 3 =15 Answer.

Answer:

see picture for the coordinates

A’ = -2,-4

B’ = -3,-7

C’ = -1,-8

D’ = 1,-6

Step-by-step explanation:

add the translation coordinates to the original to get new coordinates

Answer:

Given translation:

Therefore,

⇒ (x, y)  →  (x - 4, y - 3)

Calculations

A (2, -1) ⇒ (2 - 4, -1 - 3) = A' (-2, -4)

B (1, -4) ⇒ (1 - 4, -4 - 3) = B' (-3, -7)

C (3, -5) ⇒ (3 - 4, -5 - 3) = C' (-1, -8)

D (5, -3) ⇒ (5 - 4, -3 - 3) = D' (1, -6)

Therefore, the new coordinates using prime notation are:

The equivalent expression of the given expressions is 2x + 5.

Expressions are statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.

The given expression is,

3 + 2x - 9 - 4x + 11 + 5x - x

There are like terms in the expression, which can be operated together.

Write terms with variables together and the constants together.

3 + 2x - 9 - 4x + 11 + 5x - x

= (2x - 4x + 5x - x) + (3 - 9 + 11)

= 2x + 5

Hence the given expression can be simplified to 2x + 5.

the missing angle or the exterior angle is 120

Step-by-step explanation:

180-60=120

Answer:

90 degrees.

Step-by-step explanation:

The square symbol at the unlabeled angle means 90 degrees. Also, a triangle's interior angles equal 180. We already have 30 and 60, so 30+60=90. Now, subtract this from 180. 180-90=90. The answer is 90 degrees.

Answer:

second option, x + 2y = 3

Step-by-step explanation:

The slope intercept form is y = mx + b

y = y coordinate

m = slope

x = x coordinate

b = y intercept

The y - intercept is when x = 0

In the table its shown that (0, 3), y = 3 so b = 3

The slope (gradient) is a number that describes both the direction and the steepness of the line.

slope = rise / run = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]

(x_1, y_1)   = coordinates of first point in the line

(x_2, y_2)  = coordinates of second point in the line

x is increasing by 1 (run)

y is decreasing by 2 (rise)

rise / run = -2 / 1 = -2

so the slope is -2

our slope intercept equation is, y = -2x + 3

Choice:

Some choice are in standard form so we need to convert to slope intercept

subtract 2x from both sides, 2x - 2x + y = 3 - 2x

subtract x from both sides, x - x + 2y = 3 - x becomes 2y = 3 - x

divided both sides by 2, 2y / 2 = (3 - x) / 2

subtract x from both sides, x - x - y = 0 - x than switch signs

Answer:

  ∠TRV and ∠WRS  or  ∠TRS and ∠WRV

Step-by-step explanation:

Vertical angles are angles that share a vertex and have sides that are opposite rays. That is, the opposites of the rays that form one of the angles are the rays that form the other angle.

__

Where lines cross, two pairs of vertical angles are formed. In your diagram, those pairs are ...

  ∠TRV and ∠WRS . . . . one vertical angle pair

  ∠TRS and ∠WRV . . . . another vertical angle pair

Additional comment

In this diagram, the ray RU is of no consequence with respect to any vertical angles. It can be ignored.

The vertical angles will each have one red ray and one blue ray as sides. These rays have end point R. No sides are shared.

Step-by-step explanation:

The amount invested in the account that earns 10% interest  is $2000.

The amount invested in the account that earns 13% interest  is $3000.

a + b = 5000 equation 1

0.1a + 0.13b = 590 equation 2

Where:

Multiply equation 1 by 0.1

0.1a + 0.1b = 500 equation 3

Subtract equation 3 from equation 1

90 = 0.03b

Divide both sides by 0,03

b = $3000

Subtract $3000 from $5000: 5000 - 3000 = $2000

Operations that can be applied to a matrix in the process of Gauss-Jordan elimination are options 1,2 and 4.

Gauss-Jordan Elimination is a matrix-based technique for solving linear equations or determining a matrix's inverse.

When using Gauss Jordan elimination, the following operations may be carried out on a matrix:

1. Replacing a row with twice that row

2. Replacing a row with the sum of that row and another row

3. Swapping row

The optional row(or column) procedures that can be employed are:

1. Alternate any two rows (or columns)

2. Scalar multiples of one row (column) are added or subtracted from another row (column) occurs when a row is substituted with the sum of another row and that row.

3. Multiply any row (or column) fully by a nonzero scalar, as seen below by substituting a row with two rows.

Hence, Gauss-Jordan elimination includes options 1,2, and 4.
