Three equivalent ratio of 36:48

Answers

To find equivalent ratios, one of two things must apply:
There are common factors of both the numerator and denominator
The numerator and denominator are common factors of other numbers.

ex. 36 and 48 are both divisible by 2, 3, 6, and 12. If you divide both the numerator and denominator by 2, your ratio is 18:24. If the numerator and denominator were divided by 3, the ratio would be 12:16. Divided by 6 would give you a ratio of 6:8, and dividing by 12 results in a ratio of 4:3.

On the other side of the spectrum, if you, say, needed five or six options, then you can multiply both the numerator and denominator by a non-zero number (You are really multiplying by one, ex. 2/2, so the ratio is equivalent. It just seems larger.) So if you did multiply it by 2/2, then your ratio would be 72:96. Hope this helps.

first,multiply both sides by 5 to get rid of the faction:
2(y-40) = 25
then, divide both sides by 2 to get rid of the 2 in the left side:

y = 12.5+40

if x = -6, which inequality is true, -5 - 3x > 10, -3 - 5x < -14 or 2-x < -3?

Answers

if x = -6
we can subtitution x to every inequality, so :
-5 - 3x > 10
-5 - 3(-6) > 10
-5 - (-18) > 10
-5 + 18 > 10
13 > 10 [true]

-3 - 5x < -14
-3 - 5(-6) < -14
-3 - (-30) < -14
-3 + 30 < -14
27 < -14 [false]

2 - x < -3
2 - (-6) < -3
2 + 6 < -3
8 < -3 [false]

So if x=-6, inequality true is -5 - 3x > 10.

Slope=5,through(3,13)

Answers

The slope equal 5 so the equation as the form y=5x+b,
(3,13) means 5(3)+b=13, hence b=-2.
So y=5x-2.

Answer:

y=5x-2.

Step-by-step explanation:

This question wants us to write the given line in a slope-intercept form, which is y=mx+b, where m is the slope and b is the y-intercept. We already know the slope, which is 5, so just insert 5 in for m. We get y = 5x = b. We're not done, however, we still need to solve for b. (3,13) equals 5(3)+b=13. This gives us our final result of b=-2. insert this into the equation for b, and the equation becomes y = 5x -2.

Rafael would have 1 card on the last page.
118-117= 1

The division is one of the four fundamental arithmetic operations. The number of pages of the album that are completely filled is 13, while the last page of the album has only 1 card.

What is Division?

The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

Given that Rafel has 118 baseball cards arranged in an album. Also, Each page of the album can hold 9 cards.

Therefore, the number of pages that will be full can be found by dividing the total number of cards available by the total number of cards that each page can have.

In the division, the quotient represents the number of pages which have 9 photos, therefore are full. And the remainder represents the number of photos that will be left on the last page.

The division can be carried out as shown below.

Hence, the number of pages of the album that are completely filled is 13, while the last page of the album has only 1 card.

I need help solving these problem 14=8-6r

Answers

14 = 8 -6r
Reorder so the common terms are on one side.
Subtract 8 from both sides.
8 -6r = 14 --> -6r = -8 +14
-6r = 6
Divide each term by -6 and simplify.

r = -1

The solution of expression is, r = 1

We have to give that,

An expression to solve,

14 = 8 - 6r

Now, Simplify the expression by combining the like terms as,

14 = 8 - 6r

Add 6r on both sides,

14 + 6r = 8 - 6r + 6r

14 + 6r = 8

Subtract 14 on both sides,

6r = 8 - 14

6r = 6

Divide into both sides by 6,

r = 6/6

r = 1

Therefore, The solution is, r = 1

What’s b = 3x + 9xy ? Solving the equation for x.

Answers

Answer:

x= [tex]\frac{b}{3+9y}[/tex] .

Step-by-step explanation:

Given :  b = 3x + 9xy.

To find :  Solving the equation for x.

Solution : We have given

b = 3x + 9xy.

Taking common 3x from right hand side

b = 3x ( 1 + 3y).

On dividing both sides by 1 + 3y .

[tex]\frac{b}{1+3y}[/tex] = 3x

On dividing both sides by 3

[tex]\frac{b}{(3+9y)}[/tex] = x .

Therefore, x =[tex]\frac{b}{(3+9y)}[/tex] .

x = b/(3 + 9y)

Further explanation

[tex]\boxed{ \ b = 3x + 9xy \ }[/tex]

In the equation, there are three variables, namely b, x, and y. The coefficients of x and xy are 3 and 9, respectively.

We need solving for x from the equation.

Let us reposition it by swapping sides. The aim is to prepare x as the subject on the left-hand side.

[tex]\boxed{ \ 3x + 9xy = b \ }[/tex]

On the left-hand side, 3x is pulled out of the brackets because it is the GCF (The Greatest Common Factor) of 3x and 9xy.

[tex]\boxed{ \ 3x(1 + 3y) = b \ }[/tex]

Both sides divided by 3(1 + 3y).

[tex]\boxed{ \ x = \frac{b}{3(1 + 3y)} \ }[/tex]

Hence, the final result is

[tex]\boxed{\boxed{ \ x = \frac{b}{3 + 9y} \ }}[/tex]

That's all the steps to get x as a subject.
