The solution to the linear equation 3(x + 5) = 1/9 is

x = -4 26/27.

The correct answer is option D; None of these choices are correct.

3(x + 5) = 1/9

open parenthesis

3x + 15 = 1/9

Substract 15 from both sides

3x = 1/9 - 15

3x = (1-135)/ 9

3x = -134/9

divide both sides by 3

x = -134/9 ÷ 3

Multiply by the reciprocal of 3

x = -134/9 × 1/3

= -134/27

x = -4 26/27

Therefore, -4 26/27 is the solution that satisfies the equation 3(x + 5) = 1/9

Angle ∠IKJ is 29.5 degrees for triangle IKJ.

A triangle is a three-sided polygon that consists of three edges and three vertices.

The given triangle is IKJ.

The angles are given as follow.

∠JIK = 53°,

∠IKJ = (82-5x), and

∠KJI = (7x+24)°.

We need to find the angle ∠IKJ .

By angle sum property of triangle, the sum of three angles is 180 degrees.

∠JIK+∠IKJ+∠KJI = 180

Fifty three plus eighty two minus five times of x plus seven times of x plus twenty four equal to one hundred and eighty.

53+82-5x+7x+24=180

Add the like terms

159+2x=180

One hundred fifty nine plus two times of x equal to one hundred eighty.

subtract 159 on both sides

2x=21

Divide both sides by 2.

x=10.5

So ∠IKJ is 82-5(10.5)=29.5 degrees.

Hence, the value of angle ∠IKJ is 29.5 degrees.

Answer:

36%

Step-by-step explanation:

People with size 7 shoes = 5

People with size 7½ = 7

People with size 8 = 9

People with size 8½ = 3

People with size 9 = 1

To find out the total, you have to add all the people up:

5 + 7 + 9 + 3 + 1 = 25

The total amount of students = 25

Since you're trying to find the percentage of students who have a shoe size of 8, you have to look at how many people have that size:

People with size 8 = 9

To find out the percentage you do:

9/25 × 100 = 36%

Therefore 36% of students have a shoe size of 8

Using the percentage writing form, we know that Ivan ate 4 pizza slices.

By dividing the value by the entire value and multiplying the result by 100, one may determine the percentage.

The percentage calculation formula is (value/total value)100%.

Add all percentages as numbered values, divide by the total number of sets, and you get the average percentage.

The results by 100.

So, we know that:

Ivan ate 40% of the pizza.

And the pizza was cut into 10 slices.

Rewrite the percentage value as:

4/100 = 0.4

We can calculate how many slices Ivan consumed by multiplying the percentage value by the number of slices:

10 + 0.4 = 4

Hence, Ivan ate 4 slices of pizza.

Therefore, using the percentage writing form, we know that Ivan ate 4 pizza slices.

Using the the Distributive Property to express 64 + 24 is 88.

This property states that multiplying the sum of two or more addends by a number produces the same result as multiplying each addend separately by the number and then adding the products together.

When you multiply a value by a sum, the distributive property of multiplication over addition is used. For instance, suppose you want to multiply 5 by the sum of 10 + 3. When we have similar terms, we usually add the numbers first and then multiply by 5. 5(10 + 3) = 5(13) = 65.

Answer:

  1180 cm³

Step-by-step explanation:

You want the volume of a prism with an L-shaped base. It is 20 cm between bases. The outside dimensions of the L are 7 cm high by 11 cm wide; the inside dimensions are 3 cm high by 6 cm wide.

The formula for the volume of a prism is ...

  V = Bh

where B is the area of the base, and h is the distance between them. We know h, but we need to find B.

The area of an L-shape is the area of the rectangle with the outside dimensions, less the area of the rectangle with the inside dimensions.

  A = LW -lw

  A = (11 cm)(7 cm) -(6 cm)(3 cm) = 77 cm² -18 cm² = 59 cm²

Using the above formula, the volume is ...

  V = (59 cm²)(20 cm) = 1180 cm³

The volume of the prism is 1180 cubic centimeters.

__

Additional comment

The dimensions of the inside of the L are found by subtracting the given width of the legs from the outside dimensions.

 7 cm -4 cm = 3 cm . . . . inside height

  11 cm -5 cm = 6 cm . . . . inside width

You can also find the area of the base by extending one or the other of the lines to divide it into two rectangles. Extending the vertical line makes the left rectangle 7 cm high by 5 cm wide. The right rectangle is 4 cm high by 6 cm wide. Then the area is 7·5 +4·6 = 35+24 = 59, as above.

Answer:

Step-by-step explanation:

To prove this statement, we can use the contrapositive. The contrapositive of the statement "If a + b > 100, then a, b, or both must be greater than 50" is "If a and b are both less than or equal to 50, then a + b is less than or equal to 100."

To prove the contrapositive, we must show that if a and b are both less than or equal to 50, then a + b is indeed less than or equal to 100. This is easy to do, because if a and b are both less than or equal to 50, then the largest possible value for a is 50 and the largest possible value for b is 50. Therefore, the largest possible value for a + b is 50 + 50, which is equal to 100.

Since the contrapositive is true, it follows that the original statement must also be true. Therefore, we have proven that if a + b > 100, then a, b, or both must be greater than 50.
