Answer:

x = 19

Step-by-step explanation:

(5x + 4)° + (x - 2)° + (3x + 7)° = 180°

(5x + x + 3x)° + (4 - 2 + 7)° = 180°

9x° + 9° = 180° → ÷9

x + 1 = 20

x = 20 - 1

x = 19

Answer:

  add 6 unit tiles

Step-by-step explanation:

The square is completed when the algebra tile grid pattern is a square. This one will be a square when 6 more unit tiles are added to fill the empty spaces at the bottom right.

We need to add 6 to complete squares.

Here we have the expression:

x^2 + 8x + 10

By looking at the image, we can see that we need to add 6 cubes of the ones with the digit 1.

That is equivalent to adding 6 to our expression (and we also subtract 6 so we don't change it) then we have:

x^2 + 8x + 10 + 6 - 6

(x^2 + 8x + 10 + 6) - 6

(x^2 + 8x + 16) - 6

(x^2 + 2*4*x + 4^2) - 6

(x + 4)^2 - 6

So we completed squares, then we conclude that we need to add 6 to complete squares.

Answer: 238 lbs

Step-by-step explanation:

x = joe's weight

y = joe's dad's weight

x + y = 336

y = x +140

Substitute for y

x + x + 140 = 336

2x + 140 =336

2x = 196

x = 98

Joe weighs 98 lbs

Now, plug that into Joe's dad's weight equation

y = 98 + 140

y = 238

Joe's dad weighs 238 lbs

Given:

The ratio of two numbers is 5:2.

To Find:

What are the other ratios which are equivalent to the above ratio?

Solution:

The given problem can be solved using the concepts of ratio and proportions.

1. It is given that the ratio of two numbers is 5:2.

2. Consider two numbers a and b such that the simplest ratio between the two numbers is a:b.

=> Ratio of the numbers a and b = a:b,

=> According to the properties of ratios the operation a:b can also be written as a/b.

=> a/b can also be written as.

=> a/b can also be written as.

=> Similarly a/b can be conclusively written as. (Where n is not equal to 0).

3. The ratio of two numbers will always remain the same even if the numerator and the denominator are multiplied with the same factor. In such cases, the ratio always remains the same.

4. 5:2 = 5/2 can also be written as,

=>  ... , . (Where n is not equal to zero).

Therefore the ratios 10:4, 15:6, 20:8, 25:10,.., 5n:2n are equal to the ratio 5:2.

The graphs of parabolas are used to represent quadratic functions and equations

From the graph, we can see that the graph of the parabola opens downward

The graph crosses the x-axis at x = 2, and it crosses the y-axis at y = -4

So, the x-intercept is x = 2, and the y-intercept at y = -4

This is the maximum point on the graph.

So, the coordinate of the vertex is (2,0)

A parabola is represented as:

[tex]y = a(x - h)^2 + k[/tex]

The parabola opens downward.

So, we have:

[tex]y = -1(x - h)^2 + k[/tex]

The vertex is (2,0).

So, we have:

[tex]y = -1(x - 2)^2 + 0[/tex]

[tex]y = -(x - 2)^2[/tex]

Hence, the equation of the parabola is [tex]y = -(x - 2)^2[/tex]

Answer:

x   8  -5

9  72   -45

-6 -48  30

Step-by-step explanation:

We have to complete the multiplication grid, where each cell is the result of multiplying the column lable by the row label.

For the blank in the first column, we have to multiply:

8×(-6)=-48

We now have to find the column label for the second column.

If we call this label x, we know that -6 times x is equal to 30.

Then, we can find x as:

(-6)×x=30

[tex]x=\frac{30}{-6}[/tex]

x=-5

Then, we can complete the first row by multiplying -5 times 9:

-5×9=-45

Then, the table becomes:

x   8  -5

9  72   -45

-6 -48  30
