Answer:

  4000

Step-by-step explanation:

40% of the number is 15% more of the number than 15% of the number is. So, 600 is 15% of the number.

  600 = 0.15n

  600/0.15 = n = 4000

The number is 4000.

__

Check

40% of 4000 is 1600. 25% of 4000 is 1000. 1600 is 600 more than 1000.

Step-by-step explanation:

Let x be the number.

Then the algebraic expression will be x^2 + 11x.

The algebraic expression in x will be : x² + 11x

Given,

Variable x,

The sum of the square of a number and eleven times the number.​

Now,

Let the variable be x .

Square of variable : x²

Eleven times of the variable x : 11x

Now combine the term to get the algebraic expression,

Follow PEMDAS

The simplified values of the expression is 97.

First we will solve what is inside the brackets that too in 1st 2nd and 3rd bracket order then we will divide after that we will multiply then we will add then subtract.

The given equation is

82 + 9 (12 ÷ 3×2) - 7

Here we will follow BODMAS rule

BODMAS stands for Brackets of order division multiplication addition and substraction. In this order we will solve our expression

82 + 9 (12 ÷ 3×2) - 7

= 82 + 9(12 ÷ 6) - 7

= 82 + 9(2) - 7

Answer:

part 2 is A: yes

Step-by-step explanation:

Option B is correct.

We have the two following equations -

A.   5 = -2(x - 1)

B.   5 = -2x + 2

We have to find out how can we get Equation B from Equation A?

According to the distributive property -

a(y + z) = (a x y) + (a x z)

According to the question -

We have -

-5 = -2(x - 1)

Using the distributive property, we can rewrite the right hand side as follows -

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

Hence, option B is correct.

Answer: 2.2 miles.

Step-by-step explanation:

I guess that we want to find the distance between Lori's and Andrea's houses.

First, we have the locations:

L = (-3, 7)

A = (-3. -4)

To find the distance (in units) between two coordinate points (a1, a2) and (b1 b2) we can use the formula:

Distance = I (a1, a2) - (b1, b2)I = √( (a1 - b1)^2 + (a2 - b2)^2)

Then in this case we have that:

Distance = √( ( -3 -(-3))^2 + (7 - (-4))^2) = √( 0 + 11^2) = 11

The distance between their houses is 11 units.

And we know that each unit represents 0.2 miles, then 11 units represent 11 times that amount, the distance in miles will be:

D = 11*0.2 miles = 2.2 miles.

ye s1.8x10-4 is greater than 7.2x10-1

Step-by-step explanation:

The number 1.8*10⁻⁴ is smaller, not larger than 7.2*10⁻¹

We have two numbers in scientific notation, these are:

1.8*10⁻⁴

7.2*10⁻¹

We want to see if the first one is larger than the second one. This is trivial to notices, because the exponent in the first number is 3 orders of magnitude smaller than the other exponent, then the first number is smaller than the second, not larger.

Answer:

y = -1.50x + 15, Domain is from 0 to 10

Step-by-step explanation:

First, look at the question carefully and highlight all the words that are important. We know that the 15 dollar giftcard is important, and we know that each song costs 1 dollar and 50 cents is important. We will make an equation out of this information. Since she is spending money, the value of X will be negated. She starts out with 15 dollars, so that will be our y-intercept. From this, the equation is y = -1.50x + 15. Next, let's look at the domain. We can see that the question asks for a suitable domain, not the domain of the function. Since she didn't have more than 15 dollars from her gift card, any domain from negative infinity until 0 will be crossed out. The x-intercept of this equation is 10, so any value above 10 will be crossed out since you cannot spend more money than you were given. The domain would now be from 1 to 10.

Answer:

(2x-5)feet

Step-by-step explanation:

The area of the rectangular garden A = Length × Width

Given the area A(x) = 2x² - 21x + 40

And the width =x-8 feet

To get the length, we will simply factorise the area function as shown;

You will just factorise the area

Factorizing 2x² - 21x+40

2x² − 21x + 40

2x² -16x - 5x + 40

2x(x - 8) -5(x - 8)

=(2x−5)(x−8)

Hence the length of the garden is

Answer:

length = [tex]8\frac{1}{6}[/tex] inches

Step-by-step explanation:

A rectangle is a quadrilateral which has opposite sides to be equal.

Area of a rectangle = length × width

Given that: Area = [tex]36\frac{3}{4}[/tex] square inches, width = [tex]4\frac{1}{2}[/tex] inches, length = l. Thus;

[tex]36\frac{3}{4}[/tex] = l × [tex]4\frac{1}{2}[/tex]

[tex]\frac{147}{4}[/tex]  = l × [tex]\frac{9}{2}[/tex]

divide both sides by [tex]\frac{9}{2}[/tex],

l = [tex]\frac{147}{4}[/tex]  ÷  [tex]\frac{9}{2}[/tex]

 = [tex]\frac{147}{4}[/tex]   x [tex]\frac{2}{9}[/tex]

 = [tex]\frac{49}{6}[/tex]

l  = [tex]8\frac{1}{6}[/tex]

Therefore, the length of the rectangle is [tex]8\frac{1}{6}[/tex] inches.

32(4x - 1) - 3x = 54 - (x+2) : Do 32 times 4 and -1 as well as -1 times x and 2

128x - 32 - 3x = 54 - x - 2 : Combine like terms

125x - 32 = 52 - x : Add x to both sides

126x - 32 = 52 : Add 32 to both sides

126x = 84 : Divide both sides by 126

Answer:

The answer is C.

Step-by-step explanation:

Given that ∠I and ∠K have the same angles so we can assume that this is an Isoceles Triangle where 2 sides are equal. So we can compare the expressions of JI and JK to get the value of x :

[tex]JI = 5x + 4[/tex]

[tex]JK = 2x + 7[/tex]

[tex]JI = JK[/tex]

[tex]5x + 4 = 2x + 7[/tex]

[tex]5x - 2x = 7 - 4[/tex]

[tex]3x = 3[/tex]

[tex]x = 1[/tex]

Next, we have to substitute the x value into the expression of JK :

[tex]JK = 2(1) + 7[/tex]

[tex]JK = 2 + 7[/tex]

[tex]JK = 9[/tex]
