Step-by-step explanation:

162+18= 180

180 divide by 18 is equal to 10

Answer:

(1, - 2 )

Step-by-step explanation:

Given the equations

9x + 2y = 5 ( subtract 9x from both sides )

2y = 5 - 9x ( divide terms by 2 )

y = 2.5 - 4.5x → (1)

7x - 3y = 13 → (2)

Substitute y = 2.5 - 4.5x into (2)

7x - 3(2.5 - 4.5x) = 13

7x - 7.5 + 13.5 = 13 , that is

7x + 6 = 13 ( subtract 6 from both sides )

7x = 7 ( divide both sides by 7 )

x = 1

Substitute x = 1 into (1) and evaluate for y

y = 2.5 - 4.5(1) = 2.5 - 4.5 = - 2

solution is (1, - 2 )

Step-by-step explanation:

12x+4y=12*7+4*4

           =84+16

            =100

3y+2x=3*4+2*7

         =12+14

         =26

Answer:

x = 21

Step-by-step explanation:

ABF is a right angle and m∠EBA + m∠EBF = m∠ABF

3x - 1 + x + 7 = 90 add like terms

4x + 6 = 90 subtract 6 from both sides

4x = 84 divide both sides by 4

x = 21

Answer:

5/4 or 1 1/4 cup of oil

Step-by-step explanation:

Let's make a ratio. 1/4:10. We need to multiply 10 by 5 to get 50 cookies and do the same on the other side of the ratio. 1/4x5=5/4 or 1 1/4 and 10x5 is 50. So our final ratio would be 5/4:50. Hope this helped.

Answer:

1.01111 is the right answer

The two number which lies between 1 and 1.11111 be : 1.01111 and 1.00111

A fraction represents a part of a whole or, more generally, any number of equal parts.

Given number is :

[tex]1 < \;\;\; < \frac{10}{9}[/tex]

1<     <1.11111

The number would be 1.01111 and 1.00111

There would be many number between this don't take the whole number, we just have to find number between 0 to 11111.

So,

1<1.00111<1.01111<1.11111

The simplified expression for the area of the frame of the photo is 8x4 = 32 sq inches.

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now it is given that,

Length of the photo = 4 inches

Width of the photo = 8 inches

Since, frame around the photo is the same width all the way around.

Therefore, area of the frame of the photo = Length x width

⇒ area of the frame of the photo = 8x4 = 32 square inches

which is the required expression for the area of the frame of the photo.

Thus, the simplified expression for the area of the frame of the photo is 8x4 = 32 sq inches.

The correct solutions for the equation 4|x + 6x| + 8 = 28 are A. x=-1 and x = 11.

To solve the equation, we need to isolate the absolute value term and then solve for x. Let's go step-by-step:

Step 1: Subtract 8 from both sides of the equation:

4|x + 6x| = 28 - 8

4|x + 6x| = 20

Step 2: Divide both sides by 4:

|x + 6x| = 20 / 4

|x + 6x| = 5

Step 3: Now, since the expression inside the absolute value can be either positive or negative, we need to solve for both cases:

Case 1: (x + 6x) is positive:

x + 6x = 5

7x = 5

x = 5 / 7

Case 2: (x + 6x) is negative:

-(x + 6x) = 5

-7x = 5

x = -5 / 7

So, the possible solutions for x are x = 5/7 and x = -5/7.

However, we need to check if these solutions satisfy the original equation:

For x = 5/7:

4|5/7 + 6(5/7)| + 8 = 4|5/7 + 30/7| + 8 = 4|35/7| + 8 = 4|5| + 8 = 20 + 8 = 28

For x = -5/7:

4|-5/7 + 6(-5/7)| + 8 = 4|-5/7 - 30/7| + 8 = 4|-35/7| + 8 = 4|5| + 8 = 20 + 8 = 28

Both solutions satisfy the equation, so the correct answers are x = 5/7 and x = -5/7. However, these are not among the given options. To find the mistake, let's double-check our steps.

We made a mistake in the original problem statement. The correct equation should be: 4|x + 6| + 8 = 28.

Now, let's solve it again:

Step 1: Subtract 8 from both sides of the equation:

4|x + 6| = 28 - 8

4|x + 6| = 20

Step 2: Divide both sides by 4:

|x + 6| = 20 / 4

|x + 6| = 5

Step 3: Now, since the expression inside the absolute value can be either positive or negative, we need to solve for both cases:

Case 1: (x + 6) is positive:

x + 6 = 5

x = 5 - 6

x = -1

Case 2: (x + 6) is negative:

-(x + 6) = 5

-x - 6 = 5

-x = 5 + 6

-x = 11

x = -11

So, the correct solutions for the equation 4|x + 6| + 8 = 28 are x = -1 and x = -11, which is option B.
