Answer:
( -3 - 7 ) ÷ 5 = -2Step-by-step explanation:
( x - 7 ) ÷ 5 = -2
( -3 - 7 ) ÷ 5 = -2
( -10 ) ÷ 5 = -2
-10 ÷ 5 = -2
The answer is -3The answer is negative 2 because if you minus negative 3 by 7 first, it will give you negative 10. When you divide negative 10 by 5, you get negative 2, which is the answer to the equation.

The number is -3
What is Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number be x
Seven less than a number
So , x - 7
Divided by five, is -2
So ,
( x - 7 ) / 5 = - 2
Multiply by 5 on both sides , we get
x - 7 = - 10
Adding 7 on both sides , we get
x = - 3
Hence, the number is - 3

Indica que medida hay que adicionar alas siguientes para obtener 1dm cúbico en cada caso a. 27cmcubicos b. 300cm cúbicos c. 0,0001 m cúbicos d. 12,000mm cúbicos
Answer:
A) Debe agregarse 973 centímetros cúbicos para obtener un decímetro cúbico.
B) Debe agregarse 700 centímetros cúbicos para obtener un decímetro cúbico.
C) Debe agregarse 0,0009 decímetros cúbicos para obtener un decímetro cúbico.
D) Debe agregarse 999988 milímetros cúbicos para obtener un decímetro cúbico.
Step-by-step explanation:
A) Sabemos que un decímetro cúbico equivale a 1000 centímetros cúbicos, entonces la cantidad a adicionar a los 27 centímetros cúbicos para obtener un decímetro cúbico es:
[tex]x = 1000\,cm^{3}-27\,cm^{3}[/tex]
[tex]x = 973\,cm^{3}[/tex]
Por tanto, debe agregarse 973 centímetros cúbicos para obtener un decímetro cúbico.
B) Sabemos que un decímetro cúbico equivale a 1000 centímetros cúbicos, entonces la cantidad a adicionar a los 300 centímetros cúbicos para obtener un decímetro cúbico es:
[tex]x = 1000\,cm^{3}-300\,cm^{3}[/tex]
[tex]x = 700\,cm^{3}[/tex]
Por tanto, deben agregarse 700 centímetros cúbicos para obtener un decímetro cúbico.
C) Sabemos que 0,0001 metros cúbicos equivalen a 0,1 decímetros cúbicos, entonces la cantidad a adicionar a 0,1 decímetos para obtener un decímetro cúbico es:
[tex]x = 1\,dm^{3}-0.1\,dm^{3}[/tex]
[tex]x = 0.9\,dm^{3}[/tex]
Por tanto, deben agregarse 0,0009 decímetros cúbicos para obtener un decímetro cúbico.
D) Sabemos que 1 decímetro cúbico equivale a 1000000 milímetros cúbicos, entonces la cantidad a adicionar 12 milímetros cúbicos es:
[tex]x = 1000000\,mm^{3}-12\,mm^{3}[/tex]
[tex]x = 999988\,mm^{3}[/tex]
Por tanto, deben agregarse 999988 milímetros cúbicos para obtener un decímetro cúbico.

Five years ago,A's age was four times the age of B.Five years hence A's age will be twice of the age of B. Find their present ages.
_______________________
best of luck ^^
And don't spam =_=
Answer:
Let us consider B’s age = X
Then A’s age = 4X
Five years ago
⇒ A’s age = 4X + 5
⇒ B’s age = X + 5
Five years hence
⇒ A’s age = 4X + 5 + 5
⇒ A’s age = 4X + 10
⇒ B’s age = X + 5 + 5
⇒ B’s age = X + 10
From the given question
4X + 10 = 2(X + 10)
4X + 10 = 2X + 20
4X – 2X = 10
2X = 10
X = 5
A’s age = 4X + 5
A’s age = 25 years
B’s age = X + 5
B’s age = 10 years

If mKN is 20° and m<T=30°, what is the measure of SP?
A. 50°
B. 80°
C. 35°
D. 25°
Answer:
Step-by-step explanation:
A
The measure of SP is 80°, therefore, option (B) is correct.
What is the arc measure?The center angle that creates the intercepted arc is what is known as the arc measure, which is measured in degrees.
Given that, mKN= 20° and m∠T = 30°.
The formula for the measure of angle ∠T is:
[tex]m\angle{T}= \frac{mSP - mKN}{2}\\30^{\circ} = \frac{mSP - 20^{\circ}}{2}[/tex]
60° = mSP - 20°
mSP = 60° + 20°
mSP = 80°
Hence, the measure of SP is 80°, therefore, option (B) is correct.

If RT bisects SU, find each measure ST, RU, SV, SU,
Answer:
ST = 23
RU = 8
SV = 5
SV = 10
Step-by-step explanation:
Use the knowledge of the properties of a kite to find the measure of ST, RU, SV, and SU as shown below:
✍️Recall: Each pair of adjacent sides of a kite are congruent/equal.
ST and TU are a pair of adjacent sides.
TU = 23
✅Therefore, ST = 23.
RU and RS are a pair of adjacent sides.
RS = 8
✅Therefore, RU = 8.
✍️ Recall: the longer diagonal of a kite bisects the shorter one. This means RT divides SU into two equal parts, namely SV and UV.
Since UV = 5, therefore,
✅SV = 5
SU = UV + SV
✅SV = 5 + 5 = 10
A bisector divides the lines it bisects into equal segments
The measures of ST, RU, SV, SU are 23, 8, 10 and 5 respectively
From the diagram, we have:
[tex]\mathbf{TU = 23}[/tex]
[tex]\mathbf{UV = 5}[/tex]
[tex]\mathbf{RS = 8}[/tex]
Because RT bisects SU, then:
[tex]\mathbf{ST = TU}[/tex]
So, we have:
[tex]\mathbf{ST = 23}[/tex]
Also, we have:
[tex]\mathbf{RU = RS}[/tex]
So, we have:
[tex]\mathbf{RU = 8}[/tex]
Also, we have:
[tex]\mathbf{SV =VU \times 2}[/tex]
[tex]\mathbf{SV =5 \times 2}[/tex]
[tex]\mathbf{SV =10}[/tex]
Lastly, we have:
[tex]\mathbf{SU =VU}[/tex]
[tex]\mathbf{SU =5}[/tex]
Hence, the measures of ST, RU, SV, SU are 23, 8, 10 and 5 respectively

A bug was sitting on the tip of the propeller blade 4 ft. Long when the propeller started to rotate. The bug held on for 3 rotations before flying away. How far did the bug travel before it flew away?
Answer:
75.39 ft
Step-by-step explanation:
r = Radius of the circle drawn by the propeller = 4 ft
Circumference of the circle is
[tex]C=2\pi r\\\Rightarrow C=2\pi 4\\\Rightarrow C=25.13\ \text{ft}[/tex]
So in one rotation the distance traveled by an ant sitting on the blade tip is 25.13 ft.
Now the ant held on for 3 rotations so distance traveled is
[tex]3\times 25.13=75.39\ \text{ft}[/tex]
The bug traveled 75.39 ft.
