Answer:
Step-by-step explanation:
Let x = the age of the youngest child
Let x + 1 = the age of the middle child
Let x + 2 = the age of the oldest child
x + x + 1 + x + 2 = 39
3x + 3 = 39
3x = 36
x = 12 years

Isaac’s dad built a shelf for his video games that is 42 inches wide.Each video game is 6/8 inches wide.How many video games can Isaac fit on the shelf ?
Answer: 56
Step-by-step explanation:
Since we are informed that Isaac’s dad built a shelf for his video games that is 42 inches wide and that each video game is 6/8 inches wide.
The number of video games that Isaac can fit on the shelf will be gotten by dividing the length of the shelf by the width of each video game. This will be:
= 42 ÷ 6/8
= 42 × 8/6
= 56
Therefore, Isaac can fit 56 video games on the shelf.

The distance of the moon from the earth is 3,84,014 km. Insert commas suitably and write the distance according to Indian and International Systems of Numeration.
Answer:
Indian system of numeration:
With the Indian system, when writing a million, a comma comes after the first three digits and then after 2 digits from thenceforth.
For instance, a million would be:
= 10,00,000
Distance to moon in Indian numeration = 3,84,014 km
International System of Numeration:
Here a comma separates a maximum of 3 digits. A million here would be:
= 1,000,000
Distance to moon is therefore:
= 384,014 km
How do you find the perimeter on s polygon?PLS HELP ME on this question
Answer:
To find the perimeter of a polygon, you just have to add the values of each side.
For example, if a rectangle has a length of 10 inches and a width of 5 inches, you would add, 10 + 10 + 5 + 5, which is equal to 30. This is found because the length of one side is 10, the other is also 10, and the width is 5, and the other is also 5.
How many solutions does the system have?
You can use the interactive graph below to find the answer.
2x + 3y = -6
3x – 4y = -12
Choose 1 answer:
A Exactly one solution
B No solutions
C Infinitely many solutions

The launch used for captain lighners scenic tours hold 170 litres of fuel. The boat uses 34L each hour. i need an equation for this please help
Answer:
The information we have is:
The boat can hold 170 L of fuel
The boat uses 34L each hour.
With this information, we can find the total amount of time that the boat can be used.
If the boat is used x hours, then it needs:
x*34L of fuel.
And the maximum amount of fuel that the boat can use uis170 L
Then we can solve:
x*34L = 170L
Now we can divide both sides by 34L to isolate x.
x = 170L/34L = 5
This means that the boat can be used for 5 hours.

Which of these variables control the parabola's direction and width? And how does it control it? F(x): ax^2+bx+c
Answer:
The leading coefficient, a.
Step-by-step explanation:
In a quadratic equation:
y = a*x^2 + b*x + c
The leading coefficient is the coefficient hat that multiplies the variable with the highest power.
In this case, is easy to see that the leading coefficient is a.
We call this the "leading" coefficient because is the coefficient that most impact has on the equation's behavior.
In the case of the quadratic equation, we know that x^2 is always a positive number and is the part that grows faster.
Then if a is a positive number, a*x^2 will be positive, and because this is the part that grows faster, the arms of the parabola will open upwards.
If a is negative, then a*x^2 will be negative, and this will cause that the arms of the parabola open downwards
Then the sign of a defines the direction of the parabola.
And a also defines the width of the parabola.
If a is a really larger number, then
a*x^2 grows really fast
This means that in a small increase of x, we may see a large increase in y, so we will have a "thin" parabola.
On the other hand, if a is really small, a large increase of x will not cause a large increase on y, so we will see a wider parabola.
Then the coefficient a (or variable, depending on which thing are you changing) is the one that controls the parabola's direction and width.

Answer:
90 km/h
Step-by-step explanation:
To solve this problem you first need to convert minutes to hours since the unit is km/h. Doing this we get half an hour (1 hour=60 mins so you divide 30 by 60) after converting you simply divide 45 by 1/2 or .5 to get the answer.

A trapezoid with base measures of 23 km and 29 km has an area of 390
km2 find the height of the trapezoid.
Answer:
height (h) = 15
Step-by-step explanation:
To figure this out, we use the formula 2 · [tex]\frac{A}{a + b}[/tex], where "A" is the area, "a" is one base measure, and "b" is the other base measure.
After plugging in the numbers into the formula, we get 2 · [tex]\frac{390}{23 + 29}[/tex], which equals 15.
