Jon ate too many holiday cookies and gaines 2.2 kilograms in December. Then he went on a diet and lost 1.5 kilograms in January. Then he lost another 3.7 kilograms in February. Jon wants to know what the total change in his weight was over these three months.

WICH OF THE FOLLOWING EQUATIONS MATCHES THE SITUATION ABOVE?

A.) 2.2+(-1.5)+(-3.7)=?

B.) 2.2+1.5-3.7=?

c.) None of the above​

Answer:

-0.03

Step-by-step explanation:

you multiply everything in the parenthesis by -0.3

so that would give you -0.15,-0.18, and 0.3

then you add all of those together and that gives you -0.03

Hey there!

Given;

(1-tan^2a) + (1+tan^2a)= 2

LHS:

=(1-tan^2a)+(1+tan^2a)

Remove brackets.

=1-tan^2a + 1 +tan^2a

Cancel "tan^2a" and "-tan^2a"

= 1+1

= 2

RHS proved....

Answer:

X= 128º

Step-by-step explanation:

A triangle is stated to have 180º. This means that since we know 2 sides of the triangle you can simply subtract them from one another.

Doing this you would get: 180 - 90 - 38 = 52º

Noticing that X is on a straight line, this would result in the fact that X is on a line of 180º.

Subtracting the angle we found in the triangle would result you with the answer of:

180 - 52 = 128º for the value of X

Answer:

x = 4

Step-by-step explanation:

Answer:29/10y=-32

Step-by-step explanation:simply find a common denominator in this case ten add them together and subtract 12 to -20 and your done

isosceles triangles means that the two bottom angles and sides are equal

therefore, you can set R and T equal to each other:

(15x-31)=(9x+11)

(get x to one side)

15x=9x+42

6x=42

x=7

now you can plug x back into the equations:

15(7)-31

105-31

74

R and T = 74

all triangles' internal angles = 180

therefore you can add the two angles then subtract them from 180

74+74=148

180-148=32

S should be 32 :)

The value of six eights minus one fourth is 1/2

An expression is a combination of numbers, variables, functions (such as addition, subtraction, multiplication or division etc.).

Example of expression includes; 5x -2 , 5/2 , x +y . When two ore more terms are joined with an operation,we can call it expression.

six eights = 6/8

one fourth = 1/4

Therefore

of six eights minus one fourth

= 6/8 - 1/4

= 6 - 2/8

= 4/8

divide through by 4

= 1/2

Therefore the value of 6/8-1/4 is 1/2

Given that the dimension of the room is

354in by 714in

let us find the area of the room

A=354x714

A=252,756in^2

The rule say 1 person occupies 3 in^2

hence x person will occupy 252,756in^2

cross multiply we have

3x=252,756

x=252,756/3

x=84252 persons will occupy the room

Answer:

-6

Step-by-step explanation:

-3/2 x 4/1 = 12/2

Simply to -6/1 or -6

The required temperature would be  -6°C at 4:00 pm, which is determined by the expression -3/2 × 4/1.

A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.

At midday, the temperature is 0 degrees Celsius. For four hours, the temperature decreases by -3/2 degrees Celsius per hour.

According to the given condition, we can write the expression as:

⇒ -3/2 × 4/1

⇒ -12/2

Apply the division operation to get the solution

⇒ -6

So, the time at which the temperature goes -6°C  is 4:00 PM.

Therefore, the required temperature would be  -6°C at 4:00 pm.

Hi there & welcome to brainly!

Answer:

Step-by-step explanation:

Let the co-ordinates of D be ( x , y )

Let D ( x , y ) be ( x1 , y1 ) and F ( 3 , 5 ) be ( x2 , y2 )

Midpoint of DF = E ( -2 , 2 )

Now, finding the co-ordinates of D :

[tex]\boxed{\sf{ midpoint = (\frac{x1 + x2}{2} , \frac{y1 + y2}{2} ) }}[/tex]

⇒ [tex]\sf{ ( - 2 , 2 ) = (\frac{x + 3}{2} , \frac{y + 5}{2} )}[/tex]

Equating corresponding elements, we get :

[tex]\sf{-2 = \frac{x + 3}{2} }[/tex]                                  

⇒ [tex]\sf{ -4 = x + 3 }[/tex]

⇒ [tex]\sf{ x + 3 = -4 }[/tex]

⇒ [tex]\sf{ x = -4 - 3}[/tex]

⇒ [tex]\sf{x = -7 }[/tex]

Again,

[tex]\sf{ 2 = \frac{y+5}{2} }[/tex]

⇒ [tex]\sf{y + 5 = 4 }[/tex]

⇒ y = 4 - 5

⇒ y = -1

Hence, The co-ordinates of D = ( -7 , -1 )
