The equation x + 7 = 2 will have the value of x as 5.

We are given the equation:

x + 2 = 7

We need to solve the equation to find the value of x.

We will first subtract 2 from both the sides:

x + 2 - 2 = 7 - 2

So, subtracting 2 from both the sides, we get that:

x = 5

the value of x for the equation will be 5.

Therefore, the equation x + 7 = 2 will have the value of x as 5.

The Perimeter of polygon ABCD = 21.6 units.

The perimeter of figure ABCD = sum of all its sides = AB + BC + CD + AD.

To find each of the sides, apply the distance formula, d = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex].

A(-5, 5)

B(0, 3)

C(-2, -2)

D(-7, 0)

AB = √[(0−(−5))² + (3−5)²]

AB = √29

AB ≈ 5.4 units

BC = √[(0−(−2))² + (3−(−2))²]

BC = √29

BC ≈ 5.4 units

CD = √[(−7−(−2))² + (0−(−2))²]

CD = √29

CD ≈ 5.4 units

AD = √[(−7−(−5))² + (0−5)²]

AD = √29

AD ≈ 5.4 units

The Perimeter of polygon ABCD = 5.4 + 5.4 + 5.4 + 5.4 = 21.6 units.

Therefore, the Perimeter of polygon ABCD = 21.6 units.

The measure of side HI is 10.74 for the triangle EFG which is similar to HIJ.

Similar triangles are those triangles which have corresponding sides in proportion to each other and the corresponding angles of two triangles are equal to each other. Similar triangles look the same but they differ in terms of the sizes of the two triangles.

In short, If two triangles are similar that means,

All corresponding angle pairs of triangles will be equal.

All corresponding sides of triangles will be proportional.

Now, it is given in the question that ΔEFG is similar to ΔHIJ then, their corresponding sides will be in proportion.

⇒ GE/EF = HJ/HI

⇒ 19/34 = 6/HI

⇒ HI = 6 x 34/19

⇒ HI = 10.74

Therefore, the measure of side HI is 10.74.

Answer:

x=44

Step-by-step explanation:

x32=10+x/2

Multiply the 2 from x over 2 to reverse the division equation.

2*x32=10+x/2*2

That results in 2 multiplying 32x and 2 multiplying the 2 in x over 2.

Because multiplication is the reverse of division, the 2's will cancel out and reduce x over to 2 to simply x.

2*32 is 64, include the x before the 64 just like the given equation exemplifies with the x before the 32.

The equation looks like the following once put together: x64=10+x

Subtract the x from the 10+x side of the equation underneath the x64.

x64=10+x

-x          -x

Which equals x63=10.

To receive the answer to this question, you have to divide the 63 on both sides.

63 divided by 63x leaves you with just the x.

63 divided by 10 leaves you with 6.3 in decimal form.

Thus, x equals 6.3.

To check if it's right, insert 6.3 for both x's.

(6.3)*32=10+(6.3)/2

Solve.

201.6=10+3.15

201.6=13.15

Clearly, this doesn't work.

So, I'm assuming you actually meant: 32=10+x/2.

Hence, you would multiply 2 on both sides.

2*32=10+x/2*2

We've established that 32*2 is 64 and the 2's would cancel out.

64=10+x

Subtract the 10 on both sides.

54=x

To see if this one is correct, plug in 54 to the x.

32=10+(54)/2

Divide 54 by 2 which equals 27.

32=10+27

32=37

Nope, that doesn't work either.

Thus, instead of multiplying by 2, we would first need to subtract the 10.

32=10+x/2

-10 -10

32-10 is 22 and it would leave the other side with just x over 2.

22=x/2

Now, we would have to multiply the 2 on both sides.

22*2=44 and x/2*2 gives us x.

So, 44=x.

Let's check.

32=10+(44)/2

32=10+22

32=32

Finally, we have our match.

In conclusion, x=44.

The number of 8-inch long pieces of ribbon that the other class cut is 9.

Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.

Given that Students in 3 art classes cut 728 inches of ribbon into 8-inch long pieces. Therefore, the number of ribbon that 3 classes together cut is,

Number of ribbon cut by 3 classes together = 728 inches / 8 inches = 91

Further, it is given that two of the classes together cut 656 inches of ribbon. Therefore, the number of ribbon that 2 classes together cut is 656.

Number of ribbon cut by 2 classes together = 656 inches / 8 inches = 82

Now, the number of  8-inch long pieces of ribbon that the other class cut can be written as,

Number of pieces cut by other class

= Number of ribbon cut by 3 classes together - Number of ribbon cut by 2 classes

= 91 - 82

= 9

Hence, the number of 8-inch long pieces of ribbon that the other class cut is 9.

Each pound of brand B costs 0.33 dollars less than each pound of brand A.

Here we need to find the cost per pound for both brands, to get that, we need to get the quotient between the costs and the number of pounds.

For brand A the cost is $37.80 and you get 35 pounds, then the cost per pound is:

A = $37.80/35 = $1.08

Then each pound for brand A costs 1.08 dollars.

Now let's do the same for brand B, the cost is $33.75, and you get 45 pounds, then the cost per pound is:

B = $33.75/45 = $0.75

Then each pound for brand B costs 0.75 dollars.

So brand B is cheaper, and the difference is:

1.08 dollars -  0.75 dollars = 0.33 dollars.

In planar geometry, an angle is a shape made up of two rays or lines that share an endpoint. The English word "angle" derives from the Latin word "angulus," which means "corner." The vertex and the two rays are referred to as the sides of an angle, respectively, and are the shared termini of two rays.

3.1

straight lines makes an angle of 180° thus ,

              x + 2x + 120 = 180

Answer: 45 yrs old

Step-by-step explanation:

Car A  = 9 yrs old

Car B = X yrs old

The ratio for the cars are

Car A : Car B

or

2 : 5

You want to make it easier to read so you make both the ratio number and the given age number (9) the same number.

Multiply Car A age by 2 to make it 18 and the Ratio 2 by 9 to make it 18. This makes them the same number. Since you did this to one side, you have to do it on the other side by multiplying the 5 by 9 which is 45.

Your new ratio is now

18 : 45

This means Car B is 45 yrs old
