what is the answer to 22 +10X=

Answers

Complete question:

what is the answer to 22 +10x = 0

Answer:

the value of x is -2.2

Step-by-step explanation:

Given;

22 +10x = 0

collect like terms

10x = 0 - 22

10x = -22

divide both sides by 10

[tex]\frac{10x}{10} = \frac{-22}{10} \\\\x = -2.2[/tex]

Therefore, the value of x is -2.2

Answers

Answer:

see explanation

Step-by-step explanation:

Complementary angles sum to 90°

∠ CBA = 31° and ∠ BAC = 59° , sum to 90° (31° + 59° = 90° )

Thus

∠ A and ∠ B are complementary angles

Quadrilateral ABCD is dilated by a scale factor of 3/2 to create quadrilateral A'B'C'D'. If quadrilateral ABCD has an area of 30, what is the area of quadrilateral A'B'C'D'?

Answers

Answer:

67.5

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are translation, rotation, reflection and dilation.

Dilation is the enlargement or reduction of an object by a factor.

The area of ABCD = AB * BC = 30

As a result of the dilation to form A'B'C'D', A'B' = 3/2 * AB, B'C' = 3/2 * BC, C'D' = 3/2 * CD and A'D' = 3/2 * AD. Hence:

Area of A'B'C'D' = A'B' * B'C' =  3/2 * AB * 3/2 * BC = 9/4 * (AB * BC) = 9/4 * 30 = 67.5

Answer:

the transformation quadrilateral ABCD undergoes is a reflection.

jackie is solving this system of linear questions: 3x+2y= 20

4x-y=30

which equations could be part of the process of solving this system?

4x+6y=20

12x+8y=80

8x-y=60

8x-2y=60

Answers

Answer: 12x+8y=80

8x-2y=60

Step-by-step explanation:

The equations that could be part of the process of solving this system are 12x+8y=80 and 8x-2y=60.

The original equation was 3x+2y= 20 and 4x-y=30. Multiplying all through by 4 gives 12x+8y=80 and 8x-2y=60.

A box of cereal states that there are 72 calories in a 3 fourth cup serving what is the unit rate for calories per cup? HHow many calories are there in 4 cups? The unit rate is _ calories per cup

Answers

Answer:

4 cups = 384 calories ; 1 cup = 96 calories

Step-by-step explanation:

Given that:

3/4 cups = 72 calories

Let Number of calories in 4 cups = x

3/4 = 72

4 = x

Cross multiply

(3/4)x = 72 * 4

(3/4)x = 288

Multiply both sides by 4/3

(3/4 * 4/3)x = 288 * 4/3

x = (288 * 4) /3

x = 384

Hence, 4 cups has 384 calories

Number of calories per cup :

4 cups = 384 calories

1 cup = 384 / 4

1 cup = 96 calories

Given that,

An egg takes 198 seconds to boil a perfect egg has an altitude of -418 m.

Also it takes 209 seconds at an altitude of 8848 m.

To find,

The domain of T.

Solution,

Domain is the set of input values for which the function is defined. The least value is -418 m and the highest value is 8848 m. So, the domain is :
