Ill Give You A Huge Virtual Bear Hug If You Answer This Right The Polygons Are Similar. Find The Values

Answers

Answer 1

Answer:

x = 12, y = 8

Step-by-step explanation:

Since we know that the two triangles are similar that means we can find the ratio. The larger triangle is two times larger, we can find that out using 7/3.5 = 2. That means x + 4 = 2y and 3y = 2x. We can solve for y using substitution. We can double the first equation. 2x + 8 = 4y. We know that 2x = 3y so we can plug that in. 3y + 8 = 4y. Solving for y, gets us y = 8. Now we can plug that into any of the prior equations. I'll use 3y = 2x. 3(8) = 2x. 24 = 2x. Divide both sides by 2. x = 12.

20y-10x=5 in slope intercept form can you explain the steps

Answers

Given:

The equation is

[tex]20y-10x+5[/tex]

To find:

The slope intercept form of the given equation.

Solution:

The slope intercept form of a linear equation is

[tex]y=mx+b[/tex]

Where, m is slope and b is the y-intercept.

We have,

[tex]20y-10x=5[/tex]

We need to isolate y. Add 10x on both sides.

[tex]20y-10x+10x=5+10x[/tex]

[tex]20y=5+10x[/tex]

Divide both sides by 20.

[tex]\dfrac{20y}{20}=\dfrac{5+10x}{20}[/tex]

[tex]y=\dfrac{5}{20}+\dfrac{10x}{20}[/tex]

[tex]y=\dfrac{1}{4}+\dfrac{x}{2}[/tex]

[tex]y=\dfrac{1}{2}x+\dfrac{1}{4}[/tex]

Therefore, the slope intercept form of the given equation is [tex]y=\dfrac{1}{2}x+\dfrac{1}{4}[/tex].

If longest out of a triangle is 3 inches longer than the shorter side. The medium size is 2 inches longer than the shorter side. If the perimeter is 26 inches, what are the length of the three sides

Answers

Answer:

Shortest side = 7 inches.

Medium side = 9 inches.

Longest side = 10 inches.

Step-by-step explanation:

Let the shortest side be x.

Translating the word problem into an algebraic equation, we have;

Shortest side = x

Medium side = x + 2

Longest side = x + 3

The perimeter of a triangle is given by the addition of all its three (3) sides.

Mathematically, the perimeter of a triangle is given by the formula;

[tex] P = A + B + C [/tex]

Substituting into the equation, we have;

26 = x + x + 2 + x + 3

26 = 3x + 5

3x = 26 - 5

3x = 21

x = 21/3

x = 7 inches.

Therefore, the length of the three sides are;

Shortest side = x = 7 inches.

Medium side = x + 2 = 7 + 2 = 9 inches.

Longest side = x + 3 = 7 + 3 = 10 inches.

Answer:

x = [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

Since you cannot subtract -1 from 4x, you multiply 2 × 4x = 8x

Now, you have 8x - 1 + 3 = 7

Seperate the 8x from the other numbers

8x = 1 - 3 + 7 ---> 6

8x = 6

Now simplify

x = [tex]\frac{6}{8}[/tex]  <----- to reduce, divide the numerator and denominator by 2

Hence,

x =  [tex]\frac{3}{4}[/tex]

B. Diana bought more sodas than boxes of pizza.
C. Diana bought 6 boxes of pizza.
D. Diana bought an equal number of sodas and pizzas

Answers

Answer:

B. I think

Step-by-step explanation:

1.50 times 86 equals 129 witch would mean Diana bought 86 sodas

8 is equal to 1 pizza so Dianna could have bought 1 pizza

86>1

8+129 is 137 so I think the answer is B.

Find the equation of a line which is parallel to y= 2/5 x + 17 and passes through (-15,12)

Answers

Answer:

y = 2/5x + 18.

Step-by-step explanation:

The line will have the same slope of 2/5.

Using the point-slope form of a line:

y - 12 = 2/5(x - -15)

y - 12 = 2/5(x + 15)

y = 2/5x + 6 + 12

y = 2/5x + 18.

Answer:

y  = (2/5)*x + 18

Step-by-step explanation:

Because the line is parallel to the line y = 2/5 x + 17, the slope of the new line has to be the same as well. So far, we have y = (2/5)*x .

Now what we can do is plug in -15 for x and see what we get for y. Because we get -6, we need 18 more to make it 12. Because of that, the y-intercept is 18 to make the equation of the line y  = (2/5)*x + 18.
