Answer 1

Answer:

If there is no 48 divided by 8 then it is 8 x _ = 48.

Step-by-step explanation:

Think about it. There are 6 times more children than adults *6 x 8 = 48.

Answer 2

Answer:

8 x______=48

Step-by-step explanation:

In the problem, they are telling you there are 48 children and 8 adults at the library. Then, they tell you how many times more adults than children are at the library. You aren't adding, and since they are saying times more, that is a sign of multiplication. Hope this helps!

How many solutions does the system have?
x + 4y = 6
2x + 8y = 12

Answers

Answer:

none :)

Step-by-step explanation:

Infinite.
Multiply the first equation by -2 to get rid of whatever variable. Lets say I wanted to get rid of the variable X to solve for Y. To do that, I'd need to make x, -2x. Now the equation is -2x -8y = -12. If you add the two equations together, you'd get 0 = 0, meaning there are infinite solutions.

Composite function is a function in another function. The composite function f(g)(x) is equivalent to 3(x³ + 5x)² -4

Composite functions

Composite function is a function in another function

Given the following functions

f(x)=3x^2-4

g(x)=x^3+5x

f(g(x)) = f(x³ + 5x)

Substitute x³ + 5x into the function f(x)

f(x³ + 5x) = 3(x³ + 5x)² -4

Hence the composite function f(g)(x) is equivalent to 3(x³ + 5x)² -4

Answer:

Step-by-step explanation:

You didn't provide us with correct choice

The centroid of a triangle is the point of intersection of its medians.

The lines that pass through the centroid of a triangle divides the side lengths of the triangle into equal halves.

The figure whose centroid is point G is triangle LMN.

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Now, From the attached image, we have the following highlights

There is no evidence that the lines that pass through point G divides the three sides of triangle ABC into equal halves

The lines that pass through point G divides the three sides of triangle LMN into equal halves

The above highlights mean that:

Point G is the centroid of triangle LMN.

Hence, the figure whose centroid is point G is triangle LMN.

the difference between two numbers is 48. the ratio of the two nukbers is 7:3. what are tge two numbers

Answers

The difference between the two numbers is 48. The ratio of the two numbers is 7 : 3. Hence, 84 and 36 are the two numbers.

Given :-

The difference between the two numbers is 48.

The ratio of the two numbers is 7 : 3.

To Find :-

The Two Numbers

Solution :-

Let the first number be 7x

And the second number be 3x

According to the Question,

⇒ 7x - 48= 3x

⇒ 7x-3x = 48

⇒ 4x = 48

⇒ x = 48/4

⇒ x = 12

1st number is= 7x = 84

2nd number= 3x = 36

Hence, 84 and 36 are the two number

Solve for x I need help ASAP!

Answers

Let's solve your equation step-by-step.

2x+9=8x+21

Step 1: Subtract 8x from both sides.

2x+9−8x=8x+21−8x

−6x+9=21

Step 2: Subtract 9 from both sides.

−6x+9−9=21−9

−6x=12

Step 3: Divide both sides by -6.

-6x/-6=12/-6

x=-2

Answer:

-2 = x

Step-by-step explanation:

First, combine like-terms. I subtracted 21 from both sides and subtracted 2x from both sides. This gave us 12 = -6x. Then, divide to solve for x. This gives us -2 = x.
