[tex]\bf{2( x + 10) =4( 2x - 1)}[/tex]

We need the value of x. So, we will break the brackets first.

[tex]\bf{2( x + 10) =4( 2x - 1)}[/tex]

[tex]\bf{2x + 20 = 8x - 4}[/tex] [ Distributive Property]

[tex]\bf{2x -8x = -20 - 4}[/tex] [ Brought x to one side and signs interchange]

[tex]\bf{-6x = -24}[/tex]

[tex]\bf{x = \dfrac{24}{6}}[/tex]

[tex]\bf{x = 4}[/tex]

Hope it helps :)

Answer: No, 1.888 is a rational number. In mathematics, the irrational numbers are all the real numbers which are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers. When the ratio of lengths of two line segments is an irrational number, the line segments are also described as being incommensurable, meaning that they share no "measure" in common, that is, there is no length ("the measure"), no matter how short, that could be used to express the lengths of both of the two given segments as integer multiples of itself.

£432.75 to 2 significant figure, is 4.3275*10²  

The term significant figures refers to the number of important single digits (0 through 9 inclusive) in the coefficient of an expression in scientific notation.

Given a term £432.75

Rounding £432.75 to 2 significant figure, we get,

432.75 = 4.3275*10²

Hence, 432.75 to 2 significant figure, is 4.3275*10²

Step-by-step explanation:

9x+21=11x-1 (corresponding angle)

-2x=-22

x=11

11x-1+5y-5=180

11*11+5y-6=180

1.05 should be it

Step-by-step explanation:

In a recursive formula, each term of the sequence is found by using the previous term.  In this case, the sequence is geometric because we are multiplying each term by the same constant, called a common ratio.

To find this common ratio, we find the percent of change between terms.  We do this by using the formula

% change = (amount of change)/(original amount)

The amount of change between the first two terms is 105-100 = 5.  This makes the percent change

5/100 = 0.05

The amount of change between the second two terms is 110.25-105 = 5.25.  This makes the percent change

5.25/105 = 0.05

However, the common ratio in the sequence is not 0.05.  This is because multiplying by this decimal would make the terms decrease instead of increasing.  In this case, we are taking 100% of the number and adding an extra 5% (0.05 = 5%); this makes our common ratio 105% = 1.05.

This gives us the recursive formula

Step-by-step explanation:

Confirmed

Answer:

7,065 meters.

Step-by-step explanation:

The problem is asking for "the difference" between two points. "The difference" means you're subtracting. The second point says it is below sea level, though. That makes it a negative number. Thus:

[tex]6960-(-105)=x[/tex]

When subtracting by a negative number, think of it as addition, since the negative cancels out the subtraction sign. This turns it into:

[tex]6960+105=7065[/tex]

There is a 7,065 meter difference between the two points.

Answer:

$3

Step-by-step explanation:

To find the value of the tip, multiply 200 by 15%.

200 x 15% = 30

Divide the tip by the number of people at the dinner (Carrie plus 9 friends = 10 people)

30 / 10 = 3

Each person should contribute $3 toward the tip.

Each person will contribute $23.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Total Bill= $200

Tip= 15%

So, the amount of bill be paid after tip

= 200+ 200 x 15%

= 200+ 200 x 15/100

= 230

Now, each of them have to pay

= 230/ 10

= $23

Hence, Each of them paid $23.

medium = x+2

largest = x+4

The smallest integer and twice the second is 12 more than the third:

x + 2(x+2)  = 12+ (x+4)

x + 2x + 4  = x +16

3x  +  4 = x + 16

Answer:

I think it's the third choice because line segments are congruent and not equal. Line segments also have little lines on top of the letters.

Step-by-step explanation:

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

Explanation:

AB = BC refers to the fact that expressions 2x+7 and 4x-3 are equivalent. They represent numbers when we replace x with some number. So after doing that replacement, we have something in the form number = number.

So this is why choice A is one of the answers.

[tex]\overline{AB} \cong \overline{BC}[/tex] says "segment AB is congruent to segment BC". The horizontal lines over the lettering indicates we have a segment. The equal sign with a squiggle over top is the congruence symbol. In geometry, we say two items are congruent if they are the same. You can think of making a clone of the object and then sliding it over. In this case, we've cloned segment AB to form segment BC.

This is why choice C is the other answer.

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

Choices B and D are close, but not quite correct. Choice B is missing the segment markers. Choice D is missing the congruence symbol. Congruence and equality are very similar ideas, so often they get mixed up.
