Based on the definition of complementary angles, the value of d is: 10.

Complementary angles can be described as two angles that have a sum of 90 degrees when added together.

Given that the two angles, 24° and (7d - 4)°, are complementary angles, it implies that their sum will give a measure of 90°. Therefore, to find the value of d, the following equation would be created based on the definition of complementary angles:

24 + (7d - 4) = 90

Open the parentheses:

24 + 7d - 4 = 90

Combine like terms:

7d + 20 = 90

Subtract 20 from both sides

7d + 20 - 20 = 90 - 20

7d = 70

Divide both sides by 7

7d/7 = 70/7

d = 10

The value of d is: 10.

Answer:

A. The surface area of a cube with side length 4 cm is 6 * (4 cm * 4 cm) = 96 square cm.

B. The total surface area of two pieces of the cube would be 2 * 96 square cm = 192 square cm. This is because cutting the cube into two equal pieces would double the total surface area of the pieces, but the surface area of each individual piece would remain the same.

Answer:

Step-by-step explanation:

Let T represent table and B represent bench. The garden table costs $62 less than the bench. T = B - 62. plug T = B - 62 into T + B = 788. B - 61 + B = 788. This gives us 425. B = 425.

The system of equations is 4.25x + 2y = 53.75, y = x + 5, and the number of bangles and breakfast sandwiches Amir bought is 12 and 7 respectively.

A formula known as an equation uses the equals sign to denote the equality of two expressions.

Given:

Amir spent a total of $53.75 on breakfast sandwiches and bagels

Each breakfast sandwich costs $4.25, and each bagel costs $2.00

Calculate the equation as shown below,

4.25x + 2y = 53.75

Here, y = number of bangles and x = number of sandwiches,

y = x + 5

Solve the equation to get the values,

x  = 7 and y = 7 + 5 = 12

Therefore, the system of equations is 4.25x + 2y = 53.75, y = x + 5, and the number of bangles and breakfast sandwiches Amir bought is 12 and 7 respectively.

Answer: the answer should be 6 units  let me know if thats an option

The solution to the equation is x = -28/9.To solve the equation 2 1/7 + 3/7(3x - 5) = -4, let's break it down step by step.

Step 1: Convert the mixed number 2 1/7 to an improper fraction. Multiply the whole number (2) by the denominator (7), then add the numerator (1). This gives us (2 * 7 + 1) / 7 = 15/7.

Step 2: Distribute the 3/7 to the terms inside the parentheses. Multiply 3/7 by each term, which gives us (3/7) * 3x = 9x/7 and (3/7) * (-5) = -15/7.

Step 3: Substitute the converted mixed number and the distributed terms back into the equation. The equation becomes 15/7 + 9x/7 - 15/7 = -4.

Step 4: Combine like terms. Add the fractions with the same denominator: (15/7 - 15/7) + 9x/7 = -4. The fractions cancel each other out, leaving us with 9x/7 = -4.

Step 5: Isolate the variable. Multiply both sides of the equation by the reciprocal of 9/7, which is 7/9. This gives us (7/9)(9x/7) = (7/9)(-4). The 7/9 on the left side cancels out, leaving x = (-28/9).

Answer:

each girl scored 1 point and each boy scored 20 points.

Step-by-step explanation:

Let $g$ be the number of points scored by each girl and $b$ be the number of points scored by each boy. We can set up the following system of equations:

$$3g + 2b = 43$$

$$3g - 2b = 11$$

We can solve this system of equations using substitution. From the first equation, we have that $3g = 43 - 2b$. Substituting this expression for $3g$ into the second equation gives:

$$3(43 - 2b) - 2b = 11$$

Solving for $b$, we get:

$$129 - 6b = 11$$

$$6b = 118$$

$$b = 19.5$$

Since $b$ must be a positive integer, the only possible value for $b$ is $20$. Substituting this value into the first equation, we get:

$$3g + 2(20) = 43$$

Solving for $g$, we get:

$$3g = 3$$

$$g = 1$$

Therefore, each girl scored $1$ point and each boy scored $20$ points.
