5/b = 45/36
Solve for B please :))

Need answer asap, tyyy

Answers

5/b=45/36
5/1•1/b=5/4
Divide by 5
1/b=(5/4)/5
1/b=5
b=0.2
First you would divide, 5/b = 45/36 = 5/b -> 5/4.

You then will multiply all terms by same value
. B • 5/b -> B• 5/4,

then cancel which leads you to 5 = B • 5/4.

Now reorder to have 5 = 5/4B. Combine multiple terms into having 5= 5/4 b -> 5 = 5b/4,


Cancel multiplied terms that are on denominator, 4 • 5 = 4 • 5b/4, 4 • 5 = 5b

Multiply numbers
4 • 5 = 5b
20 = 5b

Divide both sides of the equation by the same term

20 = 5b
20/5 = 5b/5

Which leaves you left with b = 4.

How do you solve these two problems please explain step by step

Answers

Answer:

1) [tex]x=15, y=41[/tex]

2) [tex]x=6, y=24[/tex]

Step-by-step explanation:

1)

The two triangles are similar by AA similarity.

That means [tex]5x-5=4x+10[/tex].

We can add [tex]5[/tex] to both sides to get [tex]5x=4x+15[/tex].

We can then subtract [tex]4x[/tex] from both sides to get [tex]x=15[/tex].

We know that the [tex](5x-5)+(6y-4)=180[/tex]  because they both lie on a straight line.

We can plug in for [tex]x[/tex] to get [tex](5(15)-5)+(6y-4)=75-5+6y-4=6y-66=180[/tex].

We can divide both sides of the equation by [tex]6[/tex] to get [tex]y-11=30[/tex].

We then add [tex]11[/tex] to both sides to get [tex]y=41[/tex].

So, [tex]\boxed{x=15, y=41}[/tex] and we're done!

2)

Because the two bases of a trapezoid are parallel, meaning adjacent top and bottom angles sum to [tex]180^{\circ}[/tex], we have that [tex]90+3y+18=180[/tex].

We can subtract a [tex]90[/tex] and an [tex]18[/tex] from both sides to get [tex]3y=72[/tex].

We then divide both sides of the equation by [tex]3[/tex] to get [tex]y=24[/tex].

We do the same thing for [tex]x[/tex]. On the other side of the trapezoid, we have that [tex]15x+30+10x=180[/tex].

We combine like terms on the left side to get [tex]25x+30=180[/tex].

We subtract a [tex]30[/tex] from both sides to get [tex]25x=150[/tex].

We divide both sides of the equation to get [tex]x=6[/tex].

So, [tex]\boxed{x=6, y=24}[/tex] and we're done!

Explain what the algebraic solution of a system of two linear equations is and what that means in terms of the graphs of the equations of the system. Use AT LEAST 2 complete sentence in
your explanation. (3 points)

Answers

The two methods of solving for systems of linear equations algebraically are the methods of substitution and elimination.

The goal of the method of substitution is to reduce a system of two linear equations in two variables to a single equation in one
variable.

The key step in using method of elimination is to obtain opposite coefficients for one of the variables so that adding the two equations eliminates this variable.

Solving systems of linear equations by graphing involves sketching the lines representing the equations to determine whether the lines intersect at a point, which is the solution of the system.

Shannon says that the lines y=-3x-4, y = -x + 6, y = -4x - 5, and y=-x-5 could represent the sides of a rectangle. Explain Shannon's error.

Answers

The adjacent sides of rectangle form 90° to each other or are

perpendicular, while the opposite sides are parallel.

The error, is that the coefficient of x, in the four equations can only take on two values, such that if one of the values is m, the other will be [tex]-\dfrac{1}{m}[/tex]

Reasons:

In a rectangle, the adjacent sides are perpendicular to each other, while

the opposite sides are parallel.

The slope of parallel lines are equal, and the slope, of a line perpendicular to another line with slope, m, is [tex]-\dfrac{1}{m}[/tex], therefore the slopes of the parallel sides should be equal, which gives;

The equations should consist of two pairs of equations of lines with equal slopes, such as the pair, y = -x + 6, and y = -x - 5The slope of the other two lines should therefore be [tex]-\dfrac{1}{-1} = 1[/tex], which gives the equations of the other two lines as y = x - 4, and y = x - 5, respectively.

Therefore;

The error, is that the coefficient of x, in the four equations can only take on two values, such that if one of the values is m, the other will be [tex]-\dfrac{1}{m}[/tex]

A number is multiplied by 3. Next, 6 is added to the product. Then, the sum is divided by 8. If the result is 6, what is the number?

Answers

Answer:

14

Step-by-step explanation:

14 x 3 = 42

42 + 6 = 48

48 ÷ 8 = 6

Therefore, the answer is 14.

Answer:

14

Step-by-step explanation:

let us call the number x for now

the number (x) is multiplied by 3 to give us

3x

then,

it is added to 6 to give

3x + 6

then, our sum is divided by 8:

(3x + 6) / 8

according to the question, the result is 6

therefore,

3x + 6 / 8 = 6

if we cross multiply,

3x + 6 = 8 ( 6 )

3x + 6 = 48

collecting like terms,

3x = 48 - 6

3x = 42

divide through by 3 to give

3x / 3 = 42 / 3

x = 14

therefore, x = 14

to reassure us of our answer,

since (3(x) + 6) / 8 = 6

and we know that x = 14,

therefore,

(3(14) + 6) / 8 = 6

(42 + 6) / 8 = 6

48 / 8 = 6

6 = 6

therefore, we are now sure that x = 14

hope this helps
