Answer:
[tex]m=18[/tex]
Step-by-step explanation:
The equation given is [tex]D=\frac{m}{v}[/tex]
and also we have that [tex]D=\frac{6}{7}[/tex], thus:
[tex]\frac{6}{7}=\frac{m}{v}[/tex]
------------
I think the question is missing which variable is defined as [tex]=m+3[/tex], so I will solve for [tex]v=m+3[/tex] since is the only other variable in the equation.
substituting [tex]v=m+3[/tex] into [tex]\frac{6}{7}=\frac{m}{v}[/tex]:
[tex]\frac{6}{7}=\frac{m}{m+3}[/tex]
and we solve for m:
[tex](m+3)(6)=7m\\6m+18=7m\\18=7m-6m\\18=m[/tex]
m is equal to 18.

Answer:
9 is the greater x and 2 is the lesser x
Step-by-step explanation:
I really don't know how to explain without simply writing it out for you, which I really can't do. But there's the answer lol
Answer:
x = 2, x = 9
Step-by-step explanation:
Given
x² - 11x + 18 = 0
Consider the factors of the constant term (+ 18) which sum to give the coefficient of the x- term (- 11)
The factors are - 9 and - 2 , since
- 9 × - 2 = + 18 and - 9 - 2 = - 11 , thus
(x - 9)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 2 = 0 ⇒ x = 2 ← lesser value
x - 9 = 0 ⇒ x = 9 ← greater value

Answer:
f = 6, g = 8
Step-by-step explanation:
The area of Δ ADE = 60 - 48 = 12 cm²
Thus
[tex]\frac{1}{2}[/tex] AD × 4 = 12, that is
2AD = 12 ( divide both sides by 2 )
AD = 6 = f
The area of ABCD = 48 cm² , thus
fg = 48 , that is
6g = 48 ( divide both sides by 6 )
g = 8
Thus f = 6 and g = 8

Answer:
no solutions
Step-by-step explanation:
−2(x−7)+3(x+5)=x+9
Distribute
-2x +14 +3x +15 = x+9
Combine like terms
x + 29 = x+9
Subtract x from each side
x+29 -x = x+9-x
29 = 9
This is never true so there are no solutions

The first three towers in a sequence are shown. The nth tower is formed by stacking n blocks on top of an n times n square of blocks. How many blocks are in the 99th tower?
Answer:
The 99th tower contains 9900 blocks.
Step-by-step explanation:
From the question given, we were told that the nth tower is formed by stacking n blocks on top of an n times n square of blocks. This implies that the number of blocks in n tower will be:
n + n²
Now let us use the diagram to validate the idea.
Tower 1:
n = 1
Number of blocks = 1 + 1² = 2
Tower 2:
Number of blocks = 2 + 2² = 6
Tower 3:
Number of blocks = 3 + 3² = 12
Using same idea, we can obtain the number of blocks in the 99th tower as follow:
Tower 99:
n = 99
Number of blocks = 99 + 99² = 9900
Therefore, the 99th tower contains 9900 blocks.

Solve the following:
A) 4x-1/2=x+7
B) 3x+2=2x+13/3
C) 2x-7/4=3+x/3
Answer:
a. 2.5
b. 2.333
c. 2.85
Step-by-step explanation:
A) 1. subtract -x on both sides 2. to get 3x-1/2=7
3. Add 1/2 on both sides 4. to get 3x=7.5
5. divide 3 on both sides 6. To get... x=2.5
B)1. Same process. 2. x+2=13/3
3. x=13/3-2 4. x= 2.33(repeating)
C) 1. same process. 2. 2x-x/3=3+7/4
3. 2x-x/3=4.75 4. Isolate -x/3
5.-x/3=4.75-2x 6. multiply both sides by 3
7. -x=14.25-6x 8. 5x=14.25
9. x= 2.85

La mama de maximo le pidio que fuera a la tienda dijo que comprara 0.5 litros de leche, el dueño de la tienda le dijo que solo tenia leche en envases de ½ litros ¿Es mas, menos o igual a la capacidad que le pidió su mama?
Answer:
1/2 litros es igual a la capacidad que le pidió su mamá.
Step-by-step explanation:
Para encontrar la respuesta debes escribir 0.5 como fracción. Para hacerlo, el numerador es el número original sin el punto decimal y para definir el denominador debes determinar cuántos digitos decimales tienes. En este caso, el número tiene un dígito decimal, por lo cual el denominador es 10. De acuerdo a esto:
0.5 se escribiría como [tex]\frac{5}{10}[/tex] y esta fracción se puede simplificar porque los dos números son divisibles entre 5:
5/5= 1
10/5= 2
Por esto, 0.5= [tex]\frac{1}{2}[/tex]
Esto significa que 1/2 litros es igual a la capacidad que le pidió su mama.

If ∠a = 35°, what does ∠b equal?
These are complementary angles.
If two angles are complementary, then
the sum of their measures is 90°.
Since we know that one of the angles measures 35°, we can find the measure of the other by taking 90 minus the measure of the original angle which in this case is 90 - 35.
So we have 90° - 35° which is 55°
So the measure of the other angle is 55°
h(t) = -20 + 11t; h(11)
Answer:
h(11) = -20 + 11 * 11 = 101
Answer:
h(11)=101
Step-by-step explanation:
This question asks us to find h(11).
Essentially, we need to find h(t) or y, when t, or x, is equal to 11.
h(t)=-20+11t
Therefore, we can substitute 11 in for every t.
h(11)= -20+11(11)
Solve according to PEMDAS( Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)
Multiply 11 and 11 first.
h(11)= -20 +121
Add 121 and -20
h(11)=101

Dr. Karuza would like to send some classes on a trip to Disneyland. She explains that in order for any classses to go, 25% of the passengers must be teachers. Aniyah explains that if 4 teachers chose 24 students from 1 class to go then the teachers will be 25% of the passengers.
Do you agree or disagree with her answer?
Answer:
No, if 4 teachers chose 24 students from 1 class to go then the teachers will not be 25% of the passengers.
Step-by-step explanation:
Given: If 4 teachers chose 24 students from 1 class to go then the teachers will be 25% of the passengers.
To find: if the given statement is correct or not
Solution:
Total number of teachers = 4
Total number of students = 24
Total number of passengers = Total number of teachers + Total number of students = 4 + 24 = 28
Here,
25% of Total number of passengers = [tex]\frac{25}{100}(28)=7\neq 4[/tex]
So, if 4 teachers chose 24 students from 1 class to go then the teachers will not be 25% of the passengers.

Step-by-step explanation:
We need to solve for w in terms of z.
The equation given is:
5w + 9z = 2z + 3w
Collect like terms:
5w - 3w = 2z - 9z

Find the volume of the rectangular prism. Express your answer as a simplified mixed number.
Answer:
414 9/16 m³
[tex]414\frac{9}{16}m^{3}[/tex]
Step-by-step explanation:
The volume of a Rectangular prism is calculated as Length × Width × Height
From the attached diagram,we can see that
The length = 8 3/8 m
The width = 6 m
The height =8 1/4 m
Converting the mixed fraction to improper fraction in other to simplify it better
The length = 67/8 m
The height = 33/4 m
The volume of the rectangular prism =
67/8 m × 6m × 33/4m
= (13266/32)m³
= 6633/16 m³
= 414 9/16 m³
= [tex]414\frac{9}{16}m^{3}[/tex]

Answer:
-21. -19.-17
Step-by-step explanation:
Let x be the smallest
x+2 next smallest
x+4 be the largest
4*(x) = 18+6(x+4)
Distribute
4x = 18+6x+24
Combine like terms
4x = 42+6x
Subtract 6x from each side
-2x = 42
Divide by -2
-2x/-2 = 42/-2
x = -21
x+2 = -19
x+4 = -17
Answer:
- 21, - 19, - 17
Step-by-step explanation:
Let y be the smallest no.
& y + 2 next smallest no.
& y + 4 be the largest no.
= 4 * (y) = 18 + 6 * (y + 4)
4y = 18 + 6y + 24
4y - 6y = 42
- 2y = 42
= - 21
The other 2 numbers are:
y + 2
= - 19
y + 4
= - 17
