Answer:
the oldest sibling is 12 years old.
The middle child is 9 years old.
The youngest child is 6 years old.
Step-by-step explanation:
Let the age of the youngest child be x
Then the oldest child will be 2x.
The middle child will be x + 3.
Since the combined age is 27;
x + 2x + x + 3 = 27
4x = 27 - 3
x = 24 / 4
x = 6
now 2x = 12 and x + 3 = 9
Answer:
oldest is 12
middle is 9
youngest is 6
all add up to 27
Step-by-step explanation
idk if i did this right but i did 27 -3 =24
then i divide 24 by 2 which is twelve (the oldest's age)
then 12 divided by 2 is 6 which is the age of the youngest one
6 + 3 is 9, which is the age of the middle one.
In the equation 6x - 2 = -4x + 2, Spencer claims that the
first step is to add 4x to both sides. Jeremiah claims that
the first step is to subtract 6x from both sides. Who is
correct? Explain.
Answer:
Spencer is correct
Step-by-step explanation:
Because adding 4x to each side will bring both numbers to a positive and that makes it easier to get the answer
Answer:
Sample Response: Both are correct. As long as inverse operations and the properties of equality are used properly, both methods will generate the same solution. They both isolate the variable on one side of the equation.

Create an
equation that has -13 and 12
as solutions.
Answer:

geography test.
35/40 ×100 is a numerical expression to describe the percentage of the questions that Alberto got correct on his geography test.
Given that, Alberto got thirty-five out of forty questions correct on his geography test.
We need to determine the
percentage of the questions he got correct, and multiply the quotient of thirty-five and forty by one hundred.
How to calculate the percentage?The following formula is a common strategy to calculate a percentage:
Determine the total amount of what you want to find a percentage. Divide the number to determine the percentage. Multiply the value by 100.Now, 35/40 ×100=87.5%
Therefore, 35/40 ×100 is a numerical expression to describe the percentage of the questions that Alberto got correct on his geography test.

Step-by-step explanation:
If a quadrilateral is inscribed in a circle which means all its vertices lie on the circumference of the circle, then it is called a cyclic quadrilateral.
The properties of the cyclic quadrilateral
Every two opposite angles are supplementary (the sum of their measures is 180°)The measure of an exterior angle at one vertex equals the measure of the interior opposite angle to this vertexIn the given figure
∵ The four vertices of the quadrilateral QRTU lie on the circle
∴ QRTU is a cyclic quadrilateral
∵ ∠ PQU is an exterior angle of quadrilateral QRTU at Q
∵ ∠RTU is the opposite interior angle to it
→ By using the 2nd property above
∴ m∠PQU = m∠RTU
∵ m∠PQU = 95°
∵ m∠RTU = x°
∴ x = 95
∵ ∠QRT and ∠QUT are opposite angles in the cyclic quadrilateral
→ By using the 1st property above
∴ m∠QRT + m∠QUT = 180° ⇒ supplementary angles
∵ m∠QRT = 110°
∴ 110 + m∠QUT = 180°
→ Subtract 110 from both sides
∴ m∠QUT = 70°
In ΔSQU
∵ ∠ PQU is an exterior angle to the Δ T vertex Q
→ That means its measure equal the sum of the measures of the
two opposite interior angles QSU and QUS
∴ m∠PQU = m∠QSU + m∠QUS
∵ m∠PQU = 95°
∵ m∠QSU = y°
∵ m∠QUS = 70°
∴ 95 = y + 70
→ Subtract 70 from both sides
∴ 25 = y
∴ y = 25

The first term in an arithmetic sequence is 12. The third term in the sequence is 4. The tenth term in the sequence is -24.
A. Write the function that could be used to find the nth term of the arithmetic sequence
B. Daelyn said that the recursive formula for this sequence could be described as, “to find the next term of the sequence, add -4 to the previous term.” Do you agree or disagree that this statement is equivalent to the explicit formula that you created in part A? Explain.
Answer:
A-> a(n)=a+(n-1)d
B-> Yes, I do agree
Step-by-step explanation:
A= a+(n-1)d
where a=the first term
n=the term's location
d= the difference between two adjacent terms
B= I agree
a3=12+2d=4.........equation 1
2d=-8
d=-4
a10=12+9d=-24.....equation 2
9d=-36
d=-4
Hence, to find the next term of the sequence, add -4 to the previous term.

the area of an equilateral triangle is 16√3 cm2, then the perimeter of the triangle is?
Answer:
24 cm
Step-by-step explanation:
The area (A) of an equilateral triangle is calculated as
A = [tex]\frac{s^2\sqrt{3} }{4}[/tex] ( s is the side length )
Here A = 16[tex]\sqrt{3}[/tex] , then equating gives
[tex]\frac{s^2\sqrt{3} }{4}[/tex] = 16[tex]\sqrt{3}[/tex] ( multiply both sides by 4 to clear the fraction )
s²[tex]\sqrt{3}[/tex] = 64[tex]\sqrt{3}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )
s² = 64 ( take square root of both sides )
s = [tex]\sqrt{64}[/tex] = 8
Thus
perimeter = 3 × 8 = 24 cm
A basketball team played six games. In those games, the team won by 9 points, lost by 18, won by
8, won by 11, lost by 3, and won by 5. What was the mean difference in game scores over the six
games?
Answer: 2
Step-by-step explanation:
From the question, we are informed that a basketball team played six games and that in those games, the team won by 9 points, lost by 18, won by 8, won by 11, lost by 3, and won by 5.
Thee mean difference in game scores over the six games will be calculated as the summation of the scores divided by 6. This. Will be:
= [9 + (-18) + 8 + 11 + (-3) + 5]/6
= 12/6
= 2
The mean difference in game scores over the six
games is; 2
We are given the points by which a basketball team either won or lost 6 games.
- Won by 9 points = +9
- Lost by 18 points = -18
- Won by 8 points = +8
- Won by 11 points = +11
- Lost by 3 points = -3
- Won by 5 points = +5
Thus;
Mean difference of the 6 games is;
(+9 - 18 + 8 + 11 - 3 + 5)/6
>> 12/6
>> 2

The length of a rectangle is 3 times the width the perimeter is 24ft find the dimensions of the rectangle
Step-by-step explanation:
let the unknown be x
length = 3x
width = x
Perimeter = 2 lengths + 2 widths
24 ft = 3x + 3x + x + x
24 ft = 8x
3 ft = x
dimensions = length × width
= 3(3) × 3
= 9 ft × 3 ft
if you wanna check,
24 ft = 3(3) + 3(3) + 3 + 3
24 ft = 24
