Answer:

x = 4

Step-by-step explanation:

You have to times 13 x 4 which is 52 so we have 52 + x now you times 13 times x which would be 13x now you would have the equation which is 52 + 13x now if you wanted to solve that you would do 13 divided by x and divide 52 by 13 which is 4 so x = 4 and now for commutative I dont know

The distributed form of the given expression is 52 + 13x. The equivalent expression by the cumulative property is 13(4 + x).

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

The commutative property of multiplication states that changing the order of factors has no effect on the product.

Given that the expression is 13(4+x).

The distributed form of the expression is,

13(4+x) = ( 13 x 4 ) + ( 13x)

13(4+x) = 52 + 13x

The equivalent expression by using the cumulative property is,

13(4 + x) = 13(x + 4)

Step-by-step explanation:

Given

See attachment

Required

Determine the values of a and b

To solve for a, we consider the first triangle.

Using Pythagoras:

[tex]a^2 = 8^2 + 5^2[/tex]

[tex]a^2 = 64 + 25[/tex]

[tex]a^2 = 89[/tex]

Take square root of both sides

[tex]a = \sqrt{89[/tex]

[tex]a = 9.4[/tex] -- approximated

To solve for b, we consider the second triangle.

Using Pythagoras:

[tex]17^2 = 12^2 + b^2[/tex]

[tex]289 = 144 + b^2[/tex]

Collect Like Terms

[tex]b^2 = 289 - 144[/tex]

[tex]b^2 = 145[/tex]

Take square root of both sides

[tex]b = \sqrt{145[/tex]

[tex]b = 12.0[/tex] --- approximated

-13.875

Step-by-step explanation: I’m is not 100%

=============================================================

Explanation:

Because we're given multiple choices to pick from, we can go through each to do trial and error.

For instance, if v = 52, then

v/13 < -7

52/13 < -7

4 < -7

but that's a false statement since 4 is not smaller than -7. Use a number line to see this. You should have -7 to the left of 4, showing that -7 is the smaller value.

Because 4 < -7 is false, this means v/13 < -7 is false when v = 52. This rules out v = 52. You should find that v = 26 and v = -39 won't work for similar reasons.

Only v = -130 works since...

v/13 < -7

-130/13 < -7

-10 < -7

This is true because -10 is to the left of -7 on the number line.

-------------------------------------------------

Another approach:

We have some unknown number v, and we're dividing by 13 to get the expression v/13. To undo this, we multiply both sides by 13

v/13 < -7

13*(v/13) < 13*(-7) .... multiply both sides by 13

v < -91

So any solution to the original inequality must be smaller than -91. This allows us to rule out v = 52, v = 26 and v = -39.

The value v = -130 is smaller than -91, so it satisfies v < -91. Therefore, v = -130 is a solution to the original inequality.

Answer:

3 3/4

Step-by-step explanation:

Each block is worth 0.5 cm (1/2)

One note - NEVER FORGET THE UNITS

L - 5 blocks (5 blocks × 0.5cm = 2.5cm)

W - 2 blocks (2 blocks × 0.5cm = 1cm)

H - 3 blocks (3 blocks × 0.5cm = 1.5cm)

Formula for Volume:

V = L × W × H

V = 2.5cm × 1cm × 1.5cm = 3.75cm (fraction can be 3 3/4)

Answer:

258.3

Step-by-step explanation:

When you're multiplying a decimal with a factor of 10, you would move the decimal places to the right, which is dependant on how many zeros the number actually has.

100 has 2 zeros, yes?

100 x 2.583 is 258.3, as you would the decimal places 2 to the right, which results in the value being 258.3.

Hope this helped! :)
