The sum of the first and third of three consecutive even integers is 154. Find the three even integers.

Answers

x + (x+2) = 154
combine like terms
2x + 2 = 154
subtract 2
2x = 154
divide by 2
x = 76

so the two numbers are 76 and 78

A.How much flour is used with 6 eggs? B.How many eggs are used with 15 cups of flour?

Answers

Final answer:

Without a ratio, we cannot answer these questions. However, if we had a ratio such as 2 cups flour to 3 eggs, we could use cross-multiplication to find the amount of flour needed for 6 eggs (12 cups) and the amount of eggs needed for 15 cups of flour (45 eggs).

Explanation:

To answer these questions, we need a ratio between flour and eggs. However, without this ratio, it's impossible to answer questions a and b correctly. Usually in cooking, the amounts of ingredients used can vary depending on the recipe.

  1. Multiply the amount of flour (2 cups) by number of eggs (6 eggs) to find the total amount of flour needed. 2x6=12, so you would need 12 cups of flour.
  2. Multiply the amount of eggs (3 eggs) by amount of flour (15 cups) to find the total number of eggs needed. 3x15=45, so you would need 45 eggs.

Find the volume of a rectangular prism if the length is 3x2, the width is 2x, and the height is x2 + 3x + 5. Use the formula V = l ⋅ w ⋅ h, where l is length, w is width, and h is height, to find the volume. 
5x^5 + 18x^4 + 30x^3
 
5x^6 + 18x^4 + 30x^3
 6x^5 + 18x^4 + 30x^3
 6x^6 + 18x^4 + 30x^3

Answers

You are given the length of arectangular prism of 3x^2, width of 2x and height of x^2 + 3x +5. You arerequired to find the volume of a rectangular prism. Using the equation V = l xw x h, we multiply the three dimensions. 

V = l x w x h
V = (3x^2)(2x)( x^2 + 3x +5)
V = 2x (3x^4 + 9x^3 + 15x^2)
V = 6x^5 + 18x^4 + 30x^3 
The volume of the rectangularprism is 6x^5 + 18x^4 + 30x^3.

Find the measure of Angle 8.

measure of angle 7 = 2x+15
measure of angle 8 = 3x

Answers

I do not understand the context of your question, you need extra information to find this out like a picture or a word problem.
If the angles equal each other you would have to solve for x when angle 7 and 8 equal each other. SO... based on that, x would equal 15. This means measure of angle 7 would equal 45 and measure of angle 8 would equal 45. This may not be true because I have no idea what you are asking

There are white, red and blue cars in a parking lot. The number of each colour car is a factor of 36. There are twice as many white cars as red cars. The number of blue cars is twice that of black cars. The number of black cars is the product of two different prime numbers. The number of red cars is a square number that is not a multiple of 2. If there are 45 cars in the parking lot, calculate how many cars of each colour there are.

Answers

Black = 2*3 = 6 cars;
Blue = 2*2*3 = 12 cars;
Red = 3^(2) cars;
White = 2*9 = 18 cars;
 The number of each colour car is a factor of 36( blue, red, white);
black + blue + red + white = 45 cars.

Answer:

45 cars.

Step-by-step explanation:

For black, 2*3=6 cars.

For blue, 2*2*3=12 cars.

For red 3 to the power of 2= 6 cars;

For white, 2*9=18 cars;

The number of each color would be a factor of 36. This means that all the cars being added equals 42.
