What is the unknown value for u:3 = 2:6

Answer:

x = -10

3(x + 4) = -18

3x + 12 = -18

3x + 12 = -18

3x = -18-12

3x = -30

x= -30/3

x = -10

Step-by-step explanation:

[tex]3(x + 4) = - 18 \\ (x + 4) = \frac{ - 18}{3 } \\ (x + 4) = - 6 \\ x = - 6 - 4 \\ x = - 10[/tex]

Answer:

First, Third, Fourth, Fifth

Step-by-step explanation:

x² + 2x - 24 = (x + 6)(x - 4) = x² - 4x + 6x - 24 = x² + 2x - 24

True.

x² - 8x + 15 = (x + 5)(x +3) = x² + 3x + 5x + 15 = x² + 8x + 15

False.

3x² + 4x + 1 = (3x + 1)(x + 1) = 3x² + 3x + x + 1 = 3x² + 4x + 1

True.

5x² - 2x - 3 = (5x + 3)(x - 1) = 5x² - 5x + 3x - 3 = 5x² - 2x - 3

True.

4x² - 49 = (2x - 7)(2x + 7) = 4x² + 14x - 14x - 49 = 4x² - 49

True.

First, Third, Fourth, Fifth

Step-by-step explanation:

Answer:

y = 18

Step-by-step explanation:

Because it's interior angles are equal, it is an equilateral triangle.

Equilateral triangles have 3 equal sides.

So:

5y - 6 = 4y + 12

reduce:

y = 18

Answer:

Mean: 3.5263157894737

Median: 3

Mode: 3

Step-by-step explanation: The mode is 3 because the mode is for which number pops up the most, which is 3.

I got the median by crossing out 8 from the left and the right of the number set and got 3 as the last number.

I got the mean by adding up all the numbers and divided it by the amount of numbers in the set.

Answer:

The answer is -3.4. If you have to round it, round it down to 3.

Step-by-step explanation:

Answer:

57 degrees

Step-by-step explanation:

in a triangle the three interior angles always add to 180°

if you add 53 and 70 you get 123

to find the missing angle you would subtract 180 from the two numbers added

180 - 123

so 57 degrees

Answer:

90

Step-by-step explanation:

The missing value is 2.56 to the nearest hundredth.

Equations using trigonometric functions that hold true for all possible values of the variables are known as trigonometric identities.

We have a right-angled triangle.

And cos(θ) = Adjacent leg / hypotenuse

cos(65°) = The missing value  / 6

The missing value = cos(65°) x 6

The missing value = 0.4226 x 6

The missing value = 2.56 to the nearest hundredth.

Therefore, the value is 2.56.

Answer: answer is 72 you can  get it by either multiplying the height and the base by two and following the formula for area of a triangle or you can divide 36 by two and multiply that by 4

Step-by-step explanation:

Answer:

72 meters

Step-by-step explanation:

Working on 1 triangle at a time

How to find the area of a triangle: Base x Height divided by 2

So: 6 x 6 = 36

36 divided by 2 = 18

Each triangle is 18 meters

18 x 4 triangles = 72 meters

Answer:

4/5 is grater than 45/100

Step-by-step explanation:

Why?

because in percentage you make the bottom # a 100 one of them already has that and when it has 100 on the bottom it tells you that the top # is the percentage so 45/100 is 45%

now to make 4/5 a percentage what times 5 = 100?

20 does

so you times the top and bottom by 20

4*20= 80

now your fraction is 80/100  (top # tells you the %)

it's 80%

80% is grater than 45%

Answer:

4/5 is greater than 45/100.

Step-by-step explanation:

In order to figure it out, you need to make both fractions have common denominators. In order to do that, you figure out this:

5 times what equals 100? It's 20.

With fractions in this situation, whatever you do to the top, you have to do to the bottom. So, you multiply 4 times 20, which is 80.

In the end, you would end up with these two fractions:

80/100 and 45/100.

Obviously, 80/100 is greater than 45/100. In the beginning, 80/100 was originally 4/5. Therefore, 4/5 is greater than 45/100.

Answer:

all numbers

Step-by-step explanation:

3x - 5(x + 6) = -2x -2(5 + 10)

Distribute on both sides.

3x - 5x - 30 = -2x - 10 - 20

Add 2x to both sides.

-2x - 30 = -2x - 30

-30 = -30

Since we get a true statement after only doing legal steps to solve the equation, the equation has an infinite number of solutions.
