Las edades de cuatro hermanos forman una progresión aritmética, y su suma es 32 años. El mayor tiene 6 años más que el menor. Halla las edades de los cuatro hermanos.
Answer:
The ages of the four siblings are: 5, 7, 9 and 11 years old.
Step-by-step explanation:
The computation of the age of the four siblings is shown below:
Given that
n = 4
a1 =? a2 =? a3 =? a4 =?
a4 = a1 + 6 years
S4 = 32
Based on the above information
As we know that
Sn = (a1 + a4) × n ÷ 2
S4 = (a1 + a4) × 4 ÷ 2
32 = (a1 + a1 +6) × 2
16 = 2a1 + 6
2a1 = 10
a1 = 10 ÷ 2
= 5
So, a4 = a1 +6
= 5 +6
= 11
a4 = a1 + (4-1) × d
11 = 5 + 3 × d
d = 6 ÷ 3
= 2
So,
a2 = a1 + d
= 5 + 2
= 7
a3 = a2 + d
= 7 + 2
= 9
Hence, The ages of the four siblings are: 5, 7, 9 and 11 years old.

Rewriting the whole as an Equivalent Fraction
2.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using 2 as the denominator :
5t 5t • 2
5t = —— = ——————
1 2
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
5t • 2 - (7) 10t - 7
———————————— = ———————

When a fraction equals zero :
3.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
10t-7
————— • 2 = 0 • 2
2
Now, on the left hand side, the 2 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
10t-7 = 0
Solving a Single Variable Equation:
3.2 Solve : 10t-7 = 0
Add 7 to both sides of the equation :
10t = 7
Divide both sides of the equation by 10:
t = 7/10 = 0.700
One solution was found :
t = 7/10 = 0.700
Summer deposited $5,800 into an account. She made no additional withdrawals or deposits. Summer earned 1.35% annual simple interest on the money in the account.
What was the balance in her account at the end of 3.5 years?
Enter the amount in the account in the box.
$
Answer:
5800 x 0.0135 = 78.3
78.3 x 3 =234.9
78.3/2 = 39.15
234.9 + 39.15 = 274.05
Your answer is 274.05
Step-by-step explanation:
Hope this helps!
The balance in her account at the end of 3.5 years is $6074.05.
What is the balance in her account at the end of 3.5 years?The balance in her account is the sum of the interest earned and the amount of money deposited.
Simple interest = amount deposited x time x interest rate
$5800 x 0.0135 x 3.5 = $274.05
Balance = $274.05 + $5800 = $6074.05

Compare the ordered pairs of the pre-image to the image to answer these questions.
Is the dilation an enlargement or reduction?
The point of dilation is about what coordinate?
What is the scale factor?
Answer:
Is the dilation an enlargement or reduction?
Reduction
The point of dilation is about what coordinate?
0,0
What is the scale factor?
1/3
Step-by-step explanation:
The dilation is a reduction. The point of dilation is about coordinate (0,0). The scale factor is 1/3.
What is a transformation?A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.
On a coordinate plane, the pre-image rectangle has points (0, 0), (6, 0), (6, -3), and (0, -3).
The image has points (0, 0), (2, 0), (2, -1), and (0, -1).
The required figure has been attached below which represents the dilation.
As we can see that the dilation is a reduction.
The point of dilation is about coordinate (0,0).
This result of dilating a given triangle with a scale factor is 1/3.

Which of the following best describes the solution of the system of equations below?
Answer:
D
Step-by-step explanation:
-8x + y = -3..... (equ 1)
9x - y = 3.....(equ2)
y = 8x - 3
-y = -9x + 3(divide both sides by -1*)
hence ..y = 9x - 3
then write y = y in terms of x
which will give you 8x - 3 = 9x - 3
and solve for x which will be N/A

y = 3/4x -7/4 or y = 0.75x -1.75
Step-by-step explanation:
The two point form of the equation of a line is useful when you are given 2 points and asked for the equation.
y = (y2 -y1)/(x2 -x1)·(x -x1) +y1
y = (35 -14)/(49 -21)·(x -21) +14 . . . . . . fill in given points
y = 21/28(x -21) +14 . . . . . . . . . . . . . . . simplify a bit
y = 3/4(x -21) +14 . . . . . . . . . . . reduce the fraction
y = 3/4x -15 3/4 +14 . . . . . . . .eliminate parentheses
y = 3/4x -7/4 or y = 0.75x -1.75
