Quadrilateral GHIJ is similar to quadrilateral KLMN. Find the measure of side KL. Round your answer to the nearest tenth if necessary.

Answers

Answer:

KL = 11.9 approximately

Step-by-step explanation:

It is stated that the two quadrilaterals are similar

if they are similar then their side lengths are proportional

So we can use that to find KL

JG/NK = GH/KL

(52.5)/17=37/KL cross multiply expressions

52.5*KL = 629 divide both sides by 52.5

KL = 11.9 approximately

Which of the following options is true about the solution to the given set of equations? (4 points)

Select one:

a.
One solution

b.
Two solutions

c.
Infinite solutions

d.
No solution

Answers

Answer:

There is no solution

Step-by-step explanation:

The slopes are the same and the y-intercepts are different.

Think of this as the slope as an amount you get per week and y-intercept as how much you start off with. You have a friend that starts off with 10 dollars and gains 5 dollars every week and you start off with 5 dollars and gains 5 dollars every week. Will you ever catch up to your friend if you and your friend don't spend any money? I don't think so. The solution to a set of equations is when both equations have the same y value with the same x value.

4 (x + 7) = 38

x=

Answers

4(x + 7) = 38

Since there is no operation sign between the 4 and parenthesis, it makes it an automatic multiplication problem.

You would use distributive property to multiply each which should leave your equation looking like this afterwards:

4x + 28 = 38
(4 times x and 4 times 7)

You would then solve it like a two step equation,

1. +28 - 28 = 0
2. 38 - 28 = 10

4x = 10

10 divided by 4 = 2.5

x = 2.5

We can recheck our work by substituting in the value of x.

4(2.5 + 7) = 38

10 + 28 = 38

When we substituted in the value, it gave us the correct inequality.

Therefore,
x = 2.5

Answer:

x = 2.5

Step-by-step explanation:

Hello!
Let's solve the equation together :)

Solve:

4(x + 7) = 38      => Over here, we want to multiply x and 7 by 4, or distribute 4 to both numbers inside the parenthesis.

4(x) + 4(7) = 38   =>See how I split the multiplication apart? That's called the Distributive Property

4x + 28 = 38      => Simplify. Now subtract 28 from both sides

4x = 10               =>Now that we multiply x by 4, we divide both sides to isolate x

x = 10/4             => Simplify

x = 2.5

Your answer is x = 2.5

Check:

Plug in 2.5 into our equation

4(x + 7) = 384(2.5 +7) = 384(2.5) + 4(7) = 3810 + 28 = 3838 = 38

Both sides match so our answer is correct.

27.659, 27.658, 27.657, 27.558

First, to compare each decimal you look at each place. You look at the tens and then ones, tenths, hundredth, and thousandth. They all start with 27, so you look at the tenth place.

27.5

27.6

27.6

27.6

5 is less than 6, so that would go last

Continue going on to the hundredth place with the rest of the numbers.

27.65

27.65

27.65

In the hundredth place,  they all have the digit five, so you go on to the thousandth place.

27.657

27.658

27.659

7 is less than 8 or 9, so that goes second to last.

8 is less than 9, so that goes after 27.657 .

9 is the biggest, so that goes first

note: we can write x ÷ 2, as  [tex]* \ \sf\dfrac{x}{2}[/tex]

She is making half batch only, So she will require the half amount of sugar which means we need to multiply 1/2 and 3/4
