Answer:

infinitely many solutions

Step-by-step explanation:

1) distribute 9 to each term inside parenthesis on left side of equation

18x+90=2(9x+45)

2)now distribute 2

18x+90=18x+90

these equations are exactly the same! this means that this equation has infinitely many solutions

Hope this helps!

Answer:

infinite solutions

Step-by-step explanation:

9(2x + 10) = 2(9x+ 45)

Distribute

18x+90 = 18x +90

Subtract 18x from each side

18x-18x+90 = 18x-18x+90

90=90

Since this is always true, the equation has infinite solutions.

difference of eleven and nine divided by two. What is the total value?

a. 9

b. 16

c. 5

d. 17

Source:

Previous question that can found at brainly

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Side of the square = 4 units

Area of the square = 4 * 4 = 16 units

2. What is the total value?

Difference of eleven and nine divided by two = (11 - 9)/2

Difference of eleven and nine divided by two = 2/2 = 1

Area of a square whose side measures four units is added to the

difference of eleven and nine divided by two = 16 + 1

Area of a square whose side measures four units is added to the

difference of eleven and nine divided by two = 17

The correct answer is D. 17

The combined result of the area of a square with a side of four units and the arithmetic expression (11 minus 9) divided by 2 is 17.

Calculating the Combined Area and Arithmetic Expression

To solve the given problem, we need to calculate the area of a square with a side of four units and add this to the arithmetic expression (11 minus 9) divided by 2. First, let's find the area of the square. The area of a square is found using the formula area = side × side. Therefore, the area of our square is 4 units × 4 units = 16 square units.

Next, we calculate the arithmetic expression. The difference of eleven and nine is 11 - 9 = 2, and dividing this by two gives us 2 / 2 = 1.

Finally, we add the area of the square to this result: 16 square units + 1 = 17. The final answer is 17.

Step-by-step explanation:

The given measurements are:

16 m, 21 m, 39 m

We know that, it is only possible to form a triangle if sum of the measures of any two lengths is always grater than the measure of third length.

[tex] \therefore \: 39 + 21 = 60 > 16 \\ \\ \: \: \: \: \: \: 16 + 39 = 55 > 21 \\ \\ \: \: \: \: \: \: 16 + 21 = 37 \ngtr39 \\ \\ \because \: last \: mathematical\: statement \: is \:\\ defying \: the \: above \: law \\ [/tex]

Therefore, it is not possible to form a triangle with given measurements.

The given lengths cannot form the sides of a triangle because they dont satisfy the sides of a triangle rule.

The sides of a triangle rule asserts that the sum of the lengths of any two sides of a triangle has to be greater than the length of the third side.

Given here, are the sides 16 m, 21 m , 39m

now if the two sides are 16, 21 then their sum is 16+21 = 37 but 37<39 thus combination of lengths cannot form a triangle

Hence, the lengths 16,21,39 cannot form the sides of a triangle

1863 [tex]meters^{2}[/tex]

Step-by-step explanation:

( 23 x 12 ) x 2 = 552

69 x 19 = 1311

 1311

+552

= 1863 [tex]meters^{2}[/tex]

The area of the complex figure is 1,863 square meters

To find the area of the complex figure, break it down into individual rectangles and then sum up their areas. The complex figure consists of two smaller rectangles and one larger rectangle.

For the first two rectangles:

- Length = 23 m

- Width = 12 m

The area of each of the first two rectangles is:

Area = Length × Width = 23 m × 12 m = 276 square meters

Now, for the larger rectangle:

- Length = 69 m

- Width = 19 m

The area of the larger rectangle is:

Area = Length × Width = 69 m × 19 m = 1,311 square meters

To find the total area of the complex figure, sum up the areas of the three rectangles:

Total Area = Area of the first two rectangles + Area of the larger rectangle

Total Area = (276 square meters + 276 square meters) + 1,311 square meters

Total Area = 552 square meters + 1,311 square meters

Total Area = 1,863 square meters

So, the area of the complex figure is 1,863 square meters. This approach demonstrates how to find the area by breaking down the complex figure into simpler shapes and summing their individual areas.

Answer:

Option C, Carina should have subtracted 3.40 from 5.27.

Step-by-step explanation:

Step 1:  Convert words into an equation

Carina spent a total of $5.27 buying a pineapple for $3.40 and some tomatoes that were on sale for $0.85 per pound.

3.40 + 0.85p = 5.27

Step 2:  Solve for p

3.40 + 0.85p - 3.40 = 5.27 - 3.40

0.85p / 0.85 = 1.87 / 0.85

p = 2.2

Answer:

Width = 5 cm

Length = 7 cm

Step-by-step explanation:

Width = w

Length = 2w - 3

Perimeter = 24 cm

2* (length + width ) = 24

2*(2w-3 +w) = 24

2*(3w -3) = 24

3w - 3 = 24/2

3w - 3 = 12

3w = 12+ 3

3w = 15

w = 15/3

w = 5cm

Length = 2w - 3 = 2*5 - 3 = 10-3 = 7 cm

length = 7 cm

Answer:

x = - 2, x = 8

Step-by-step explanation:

The absolute value function always returns a positive value, but the expression inside can be positive or negative, thus

x - 3 = 5 OR - (x - 3) = 5

Solving both equations

x - 3 = 5 ( add 3 to both sides )

x = 8

OR

- x + 3 = 5 ( subtract 3 from both sides )

- x = 2 ( multiply both sides by - 1 )

x = - 2

As a check

Substitute these values into the left side of the equation and if equal to the right side then they are solutions.

x = 8

| 8 - 3 | = | 5 | = 5 = right side

x = - 2

| - 2 - 3 | = | - 5 | = 5 = right side

Thus the solutions are x = - 2, x = 8

The equation given is the same as x - 3 = 5 or -(x - 3) = 5

Steps to solve:

x - 3 = 5

x - 3 + 3 = 5 + 3

x = 8

Steps to solve:

-(x - 3) = 5

-x + 3 = 5

-x + 3 - 3 = 5 - 3

-x = 2

-x/-1 = 2/-1

x = -2

Therefore, the solutions are x = 8 and x = -2

Answer:

The equation of the line in the slope-intercept form is y = [tex]\frac{4}{3}[/tex] x + 4 ⇒ A

Step-by-step explanation:

The slope-intercept form is y = m x + b, where

The formula of the slope of a line which passes through points [tex](x_{1},y_{1})[/tex] and [tex](x_{2},y_{2})[/tex] is [tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

∵ The line passes through points (-6 , -4) and (0 , 4)

∴ [tex]x_{1}[/tex] = -6 and [tex]x_{2}[/tex] = 0

∴ [tex]y_{1}[/tex] = -4 and [tex]y_{2}[/tex] = 4

- Substitute them in the formula of the slope

∴ [tex]m=\frac{4--4}{0--6}=\frac{8}{6}[/tex]

- Simplify it by divide up and down by 2

∴ [tex]m=\frac{4}{3}[/tex]

∵ The slope-intercept form is y = m x + b

- Substitute the value of m on it

∴ y = [tex]\frac{4}{3}[/tex] x + b

∵ b is value y at x= 0

∵ At x = 0 , y = 4 ⇒ given point

∴ b = 4

- Substitute the value of b in the equation

∴ y = [tex]\frac{4}{3}[/tex] x + 4

The equation of the line in the slope-intercept form is y = [tex]\frac{4}{3}[/tex] x + 4

The measure of each base angle is 56°.

Step-by-step explanation:

base angle + base angle + 68° = 180°

2x + 68° = 180°

2x = 112°

x = 112/2

x = 56°

Therefore, the measure of each base angle is 56°.

The required measure of each base angle is equal to 56°.

It involves understanding the properties of an isosceles triangle, which is the key to solving the problem. In an isosceles triangle, if two sides are equal, the angles opposite those sides are also equal.

Given that Kay is drawing a triangle with two equal sides of 8 cm and the angle between these sides measures 68°, the triangle is isosceles, and we know that the other two angles (the base angles) are equal due to this property.

The sum of all angles in any triangle equals 180°. Therefore, to find the measure of each base angle, we subtract the given angle from 180° and then divide by 2 (since the base angles are equal):

The sum of angles in a triangle = 180°.

The measure of the angle between the two sides = 68°.

The sum of the two base angles = 180° - 68° = 112°.

Measure of each base angle = 112° / 2 = 56°.

Therefore, the measure of each base angle in Kay's triangle is 56°.

Step 3:

Let us expand it further as [tex]1+48X-72=-2[/tex]

Step 4:

To find X segregate X in one side and all other remaining terms in other side as follows

[tex]48X=-2+72-1[/tex]

After the simplification the numerical value is

[tex]48X=69[/tex]

Step 5:

Keep X along one side and bring 48 to the denominator of another side to find X as follows

[tex]X=69/48[/tex]

Answer:

x = 1 7/16

Step-by-step explanation:

1 + 1 2 ⋅ (4x − 6) = −2

Subtract 1 from each side

1-1 + 1 2 ⋅ (4x − 6) = −2-1

1 2 ⋅ (4x − 6) = −3

Distribute the 12

48x -72 = -3

Add 72 to each side

48x-72+72 = -3+72

48x =69

Divide by 48

48x/48 = 69/48

x =1 21/48

x = 1 7/16

Step-by-step explanation:

so for the first equation I would keep 1/3 the same

flip the division sign to multiplication

and turn the second fraction 4/10 upside down so it becomes 10/4

10/12 can be simplified by dividing 2 on the numerator and denominator

10/2=5

12/2=6

5/6

for the second equation I know that each number in the first equation should be present in the second(since they are all the same numbers). However, 5/6 is not present in the second equation so that is the missing number
