If we multiply a number by 5, then we add it by 3.5, and we divide the result by 2, and from the new result we subtract 7.6 we obtain 6.65. Find out the number.

Answer:

1.5

Step-by-step explanation:

-1.5 + 1.5 will get you to 0

-1.5 + (-1.5) will get you -3. The other options are out of the question

Answer:

30

Step-by-step explanation:

infinite solutions cause when you take out the 2 from the bottom equation, you get x + y = 4, which is the exact same equation as the first one, so literally any two values will result in the same for both

Answer:

0.5

Step-by-step explanation:

How to Find the Mean. The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

When we add them, it's 2.5.

Now we divide.

Answer:

0.5

Step-by-step explanation:

2+(-2.5)+(-1)+0+4 =2.5

2.5/5 = 0.5

Answer:

319in

Step-by-step explanation:

cut them by sections

3×14=42 is the top of the shape

then the middle rectangle, add 24 with 5, it's 29

8×29=232

then the last one which is the bottom right rectangle

9×5=45

after add 42+232+45 and that's your answer

The area of the Composite figure is 319 sq units.

A two-dimensional figure made up of basic two-dimensional shapes such as triangles, rectangles, circles, semicircles, etc

Given that a Composite figure with sides measurements

We will calculate the area by diving the figure in three rectangles  

Area of a rectangle = length * width

Therefore, 9*5 + 8*29 + 3*14 = 45 + 232 + 42 = 319 sq units

Hence, The area of the Composite figure is 319 sq units.

Answer: 1 3/4 cups of sugar

Step-by-step explanation:

To make the first recipe, Luis needs 1 1/4 cup of sugar.

To make the second recipe, he needs 1/2 cup of sugar.

The number of cups of sugar that he need to make both recipes will be gotten by adding both cups of sugar together. This will be:

= 1 1/4 + 1/2

= 1 1/4 + 2/4

= 1 3/4

Therefore, 1 3/4 cups of sugar are needed

Step-by-step explanation:

Given that,

The maximum angle for a wheelchair ramp entering a business at 4.76 degrees.

We need to find the horizontal distance needed to accomidate a ramp that goes up to a door 4 feet of the ground.

We can solve it using trigonometry.

[tex]\tan\theta=\dfrac{h}{d}[/tex]

Where

h is height

d is the angle of elevation

[tex]d=\dfrac{h}{\tan\theta}\\\\d=\dfrac{4}{\tan(4.76)}\\\\d=48.03\ ft[/tex]

So, the horizontal distance is equal to 48.03 feet.

lets do this step by step.

First: we need to break this into to prisms.

Next lets say the dimensions:

4 x 2 x 1 and 2 x 2 x 1

now we multiply them and then add them
