Expand and simplify 4(2x +7) – 3(x + 5)

Answer:

5

Step-by-step explanation:

Let the number of true or false questions be x.

2x+(20-x)6=100

2x+120-6x=100

-4x=-20

x=5

Ans: There are true or false questions

Answer:

2x = x+1 + 18

---

x = 19

-----------

x+1 = 20

Step-by-step explanation:

The smaller of the two consecutive even integers is 20, and the larger is 22.

A numeral system is a way of writing numbers; it's a way of mathematically notating a collection of numbers by utilizing a consistent set of digits or other symbols.

Let's call the smaller of the two consecutive even integers "x".

Since the integers are consecutive and even, we know that the larger integer must be 2 more than the smaller integer. Therefore, we can represent the larger integer as "x + 2".

According to the problem statement, two times the smaller integer (2x) is 18 more than the larger integer (x + 2). We can express this algebraically as:

2x = x + 2 + 18

Simplifying this equation, we can combine like terms on the right-hand side:

2x = x + 20

Subtracting x from both sides, we get:

x = 20

Therefore, the smaller of the two consecutive even integers is 20, and the larger is 22 (since 20 + 2 = 22).

Step-by-step explanation:

Giving the following information:

$175 at 5.45% for 36 months

First, we need to determine the monthly interest:

Monthly interest= 0.0545/12= 0.004542

Now, we will calculate the interest earned using both simple and compound interest:

Simple interest:

I= P*r*t

I= 175*0.004542*36

I= $28.61

Compound interest:

I= PV*(1+i)^n - PV

I= 175*(1.004542^36) - 175

I= $31.01

Step-by-step explanation: it’s parallel so it must have the same slope as line C.

Answer:

The equation in the slope-intercept form will be:

Step-by-step explanation:

Given

Important Tip:

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

In our case,

Step 1 of 2

Determine the y-intercept b

substitute m = -1/2 and (x, y) = (6, -4) in the slope-intercept form of the line equation

[tex]y = mx+b[/tex]

[tex]-4\:=-\:\frac{1}{2}\left(6\right)+b[/tex]

switch sides

[tex]-\frac{1}{2}\left(6\right)+b=-4[/tex]

[tex]-3+b=-4[/tex]

Add 3 to both sides

[tex]-3+b+3=-4+3[/tex]

simplify

[tex]b=-1[/tex]

Thus, the y-intercept b = -1

Step 2 of 2

substitute the values

substitute b = -1 and m = 1/2 in the slope-intercept form of the line equation

[tex]y = mx+b[/tex]

[tex]y=-\frac{1}{2}x+\left(-1\right)[/tex]

[tex]\:y=-\frac{x}{2}-1[/tex]

Conclusion:

Therefore, the equation in the slope-intercept form will be:

[tex]\:y=-\frac{x}{2}-1[/tex]

Whre is the question I don't get it

The values of P and Q are 270 units and 367 units respectively.

In a right-angled triangle, the sum of the squares of the smaller two sides of a right-angle triangle is equal to the square of the largest side.

We know, From Pythagoras's theorem hypotenuse² = base² + height².

So, p² = 179² + 203².

p = [tex]\sqrt{179^2 + 203^2[/tex].

p = [tex]\sqrt{32041 + 41209[/tex].

p = [tex]\sqrt{73250[/tex].

p = 270.

Now, we can find q.

q = [tex]\sqrt{250^2 + 270^2[/tex].

q = [tex]\sqrt{62500 + 72900[/tex].

q = [tex]\sqrt{135400[/tex].

q = 367.

Answer:

You would need 18 litres more of white paint to create Citron Green paint.

Step-by-step explanation:

Given the Green Apple paint contains 24 litres of green paint in a 2:1 ratio with white paint, we can conclude the mixture contains 12 litres of white paint because 24 / 2 = 12.

In a Citron Green paint mixture, the current paint mixture would contain 24 litres of green paint in a 4:5 ratio with white paint. This would mean there are 30 litres of white paint in this mixture.

24 / 4 = 6

5 x 6 = 30

To make Citron Green paint, you would need 18 litres more of white paint.

30 - 12 = 18

The amount of white paint that needs to be added is required.

He needs to add 75 liters of white paint.

Let x be amount of green paint

y be amount of white paint.

Amount of apple green paint is 90 L, so

[tex]x+y=90[/tex]

The ratio of green to white paint is 2:1, so

[tex]\dfrac{x}{y}=\dfrac{2}{1}[/tex]

Rearranging the equation

[tex]x=2y[/tex]

Substituting in the first equation

[tex]2y+y=90\\\Rightarrow y=\dfrac{90}{3}\\\Rightarrow y=30\ \text{L}[/tex]

Amount of white paint is 30 L.

Amount of green paint is [tex]x=2y=2\times 30=60\ \text{L}[/tex]

Amount of green paint added to the apple green paint is 24 L.

Amount of green paint in the mixture is 60+24 = 84 L.

Let the amount of white paint to be added in the mixture be y.

This will be added to the 30 L of white paint in the original mixture.

The ratio of green:white = 4:5, so

[tex]\dfrac{84}{y+30}=\dfrac{4}{5}\\\Rightarrow \dfrac{84\times 5}{4}=y+30\\\Rightarrow 105=y+30\\\Rightarrow y=105-30=75[/tex]

The amount of white paint to be added is 75 L.

Answer:

y = -2x + 2

Step-by-step explanation:

y = mx + b

b is the y-intercept and is 2.

m is the slope.

Start at (0, 2), the y-intercept. Go down 2 units and right 1 unit.

That is a rise of -2 and a run of 1.

m = slope = rise/run = -2/1 = -2

The formula for an exponential decay problem is: y = x (1 - r)^x

Where x = initial amount, r = rate of decay and x = # time periods

So, x = $258, r = 8% = .08 and x = 11 years

y = 258 (1 - 0.08)^11 = 258 (0.92)^11 = 258 * 0.3996 = $103.10

Step-by-step explanation:

I believe it is 16.75 because 0.35 + 16.4 is 16.75 why is it addition decimals? Because it says How many milliliters does the mixture contain. It is talking about both combined, I hope this helps you if not sorry this was rushed! I am also 3rd Grade this Year! :D

The total mixture is 16.75 ml

Mixture is a combination of two or more elements to form a third element.

Given here, Jada mixes 0.35 ml to 16.4 ml milk and therefore the total mixture is equal to 0.35 + 16.4 = 16.75 ml

Hence Jada's mixture contains 16.75 ml
