Answer:

18

Step-by-step explanation:

All the angles added up will equal 180 degrees (recall a straight line has an angle of 180 degrees).

Therefore, you can create the following equation and solve for x:

[tex]2x+3x+2x+3x=180\\10x=180\\x=\frac{180}{10}\\x=18[/tex]

Answer:

x=18

Step-by-step explanation:

equation: 90=2x+3x

Answer:

Step-by-step explanation:

To solve this, we would use the formula for calculating simple interest which is:

Interest = PRT

Then, we will slot in the values given which will be:

84 = P × 3% × 7

84 = P × 0.03 × 7

84 = 0.21P

P = 84/0.21

P = $400

The Principal is $400

Answer: The third option, 3y^6/x^5z^12

Step-by-step explanation:

Answer:

See explanation

Step-by-step explanation:

The correct answer is obviously 3 because if we substitute x = 6 into the expression we get ( 12 + 6 ) / 6. Using the order of operations, we get 18 / 6 = 3.

The friend likely didn't use the order of operations when evaluating. It's most likely that he substituted x = 6 into the expression and got ( 12 + 6 ) / 6. Instead of first adding 12 and 6, he divided 6 by 6 first to get 1, then added 12 to get 13.

Answer: Andre

Step-by-step explanation: coz I juss know..

Answer:

Andre

Step-by-step explanation:

This situation can be modeled with the equations:

A = 100 + 5w

E = 10 + 20w

Let w represent the number of weeks that have passed since they have started saving money. Andre(A) has saved $5 per week and Elena(E) has saved $20 per week. Substituting 4 into the equation (because 4 is the number of weeks that have passed so far) and evaluating we come to the realization that Andre still has more money than Elena because he now has $120 and Elena has $90.

Answer:

1,211

Step-by-step explanation:

Here, we are to find the sum of 535 plus 676

Mathematically, that would be adding up both values

By adding up both values, our answer is 1,211

Answer:

The sum of the three inside angles of a triangle need to equal 180 degrees.

X = 180 - 79 - 73

x = 28 degrees

Answer:

x= 42

Step-by-step explanation:

x/2+9=30

x+18=60

x=60-18

x= 42

Step-by-step explanation:

n= nickels

q= quarters

Create a system of equations

n + q =72 number of coins

0.05n + 0.25q = 12 amount in money

solve by elimination ( anything would be fine)

n + q = 72

4( 0.05n + 0.25q = 12)

n+ q = 72

-

0.2n + q = 48

0.8n = 24

n= 30

now use substitution to find how many quarters she has

30 + q = 72

q = 42

He has 30 nickels and 42 quarters

Sorry for skipping some steps

I hope this helps!!!

Answer:

Step-by-step explanation:

Determining the expression for the sequence:

Given the sequence

10,  11,  12,  13

Here, the first element is:

a₁ = 10

An arithmetic sequence has a constant difference 'd' and is defined by  

[tex]a_n=a_1+\left(n-1\right)d[/tex]

computing the differences of all the adjacent terms

[tex]11-10=1,\:\quad \:12-11=1,\:\quad \:13-12=1[/tex]

The difference between all the adjacent terms is the same and equal to

[tex]d=1[/tex]

now substituting d = 1 and a₁ = 10 in the nth term

[tex]a_n=a_1+\left(n-1\right)d[/tex]

[tex]a_n=\left(n-1\right)+10[/tex]

[tex]a_n=n+9[/tex]

Determining the value of the 9th term

Given the nth term

[tex]a_n=n+9[/tex]

substituting n = 9 to determine the 9th term

[tex]a_9=9+9[/tex]

[tex]a_9=18[/tex]

Therefore, the vale of the 9th term is:

[tex]a_9=18[/tex]

Answer:

12 hours and 4 minutes

Step-by-step explanation:

To solve first convert both terms to minutes. Do this by multiplying the number of hours by 60, then adding the remaining minutes. 8*60=480, then 480+39=519 minutes. Next, convert 3 hours and 25 minutes to 205 minutes. So now we have 519 minutes and 205 minutes, so add those together to get 724 minutes. Finally, convert back to hours to 12 hours and 4 minutes by dividing by 60.

Answer:

53, 55

Step-by-step explanation:

by the triangular inequality theorem, in a triangle.. sum of two sides is always greater than the third side.

3+54=57  ... exclude 57 and 58

3+51=54   ... exclude 51

Answer:

14.40

Step-by-step explanation:

20%=0.20

20% of 18 is 18(0.2)=$3.6

$18-$3.6= $14.4

the discount price is $14.4

18 divide by 4 is what you would need to re add so I think it is 24

3 - b

Answer:

The rewritten is x + 1.5y.

It can be concluded that Lloyd earns $0.5 per hour more than Harry.

Step-by-step explanation:

Given;

8x + 12y

The expression can be rewritten by dividing it through by 8 as follows:

(8 / 8)x + (12 / 8)y = x + 1.5y

Therefore, the expression can be rewritten as x + 1.5y.

Since x represents the number of hours Harry worked and y represents the number of hours Lloyd worked, the new expression implies that Harry earns $1 per hour while and Lloyd earns $1.5 per hour. Therefore, it can be concluded that Lloyd earns $0.5 per hour more than Harry.

Answer:

Distance=4.24

Step-by-step explanation:

By the Pythagorean Theorem:

3^2+3^2=distance^2

9+9=distance^2

Distance=4.24

Z = xy

To solve for y, divide both sides by x.

Y = z/x

Answer:

[tex]\underline{z = xy} \\ \boxed{ y = \frac{z}{x} }[/tex]

Answer:

200

Step-by-step explanation:

Given that :

Slope intercept equation :

y=200x+10000

The number of spots being added per year is the value of slope in the equation ;

The general form of a slope intercept equation is :

y = mx + c

Where m = slope

Comparing the equation given to the general formula ; m corresponds to 200 ; hence number of spots added per year = 200

Subtract sin (8x − 10) from both sides of the equation.

cos (6x − 12) − sin (8x − 10) = 0

Answer:

It doesn't exist

Step-by-step explanation:

since :

cos (90° – x) = sin x

cos(x) = sin(pi/2 - x)

then

cos(6x-12) =! sin(8x-10)

since (8x-10) =! (pi/2- 6+12)

then this identity of cos(6x-12) = sin(8x-10) doesn't exist

Answer:

4. (-8) - (+3)

Step-by-step explanation:

This answer does not result in an answer of -5

This subtracts -3 from -8, which gives you the answer of -11.

So, this answer is correct because it is the one that doesn't result in -5.

Answer:

Problem #4

Step-by-step explanation:

Some things to remember when doing problems like are

Double negative = positive

Double positive = positive

Negative & positive = negative

1. (-7) + (+2)          2. (-11) + (+6)        3. (-9) - (-4)        4. (-8) - (+3)

    -7 + 2                   -11 + 6                  -9 + 4                -8 - 3

       -5                          -5                         -5                     -11
