t+5h=112

B. 13(t-h)=220
6(t-h=112

C. 8t+5h=220
5t+h=112

Answer:

slope is 2

Step-by-step explanation:

Answer:A

Step-by-step explanation:

|(1/2 + 7/8i)^n| is grater than 1.

A complex number is a number of the form a + bi, where a and b are real numbers ; This way, a complex number is defined as a polynomial.

Here, given that,

|(1/2 + 7/8i)^n|

where, n>1

then , we get,

|(1/2 + 7/8i)^n| is grater than 1.

Answer:

the diameter of square 10× five ten of the fraction and 9+10=21 is to add the same and multiply the numbers by 100000

Step-by-step explanation:

9+10=21

Answer:

You can put this solution on YOUR website!

the inequality is 500 - 25x >= 200

this insures that he will have at least 200 at the end of the summer.

subtract 200 from both sides of that inequality and add 25x to both sides of that inequality to get 500 - 200 >= 25x

simplify to get 300 >= 25x

divide both sides of that equation by 25 to get 300 / 25 >= x

simplify to get 12 >= x

12 >= x means x <= 12.

when x is smaller than or equal to 12, he will be guaranteed to have at least 200 in the account at the end of the summer.

when x = 12, what is left in the account is 500 - 25 * 12 = 200.

when x = 11, what is left in the account is 500 - 25 * 11 = 225.

when x = 13, what is left in the account is 500 - 25 * 13 = 175.

the maximum number of weeks he can withdraw money from his account is 12.

Answer:

17 t-shirts sold

Step-by-step explanation:

If we assume that we don't need t find the number of hats, then we can say that the profit from -tshirts would be $125 minus 40 or $85

Then we can write the following equation of x is the number of t-shirts:

5x = 85

If we solve by diving both sides of the equation by 5:

5x/5 = 85/5

x = 17 t-shirts sold

Answer:

see explanation

Step-by-step explanation:

z - w

= 1 - 3i - (- 2 + 5i) ← distribute parenthesis by - 1

= 1 - 3i + 2 - 5i ← collect like terms

= 3 - 8i

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

z × w

= (1 - 3i)(- 2 + 5i) ← expand using FOIL

= - 2 + 5i + 6i - 15i² [ i² = - 1 ]

= - 2 + 11i + 15

= 13 + 11i

[tex] \frac{3x}{x - 2} = 7 \\ [/tex]

Multiply sides by ( x - 2 )

[tex](x - 2) \times \frac{3x}{x - 2} = (x - 2) \times 7 \\ [/tex]

Simplification

[tex]3x = 7x - 14[/tex]

Subtract sides 7x

[tex] - 7x + 3x = - 7x + 7x - 14[/tex]

Simplification

[tex] - 4x = - 14[/tex]

Negatives simpliflies

[tex]4x = 14[/tex]

Divide sides by 4

Answer:

x = [tex]\frac{7}{2}[/tex]

Step-by-step explanation:

Given

[tex]\frac{3x}{x-2}[/tex] = 7 ( multiply both sides by x - 2 )

3x = 7(x - 2) ← distribute

3x = 7x - 14 ( subtract 3x from both sides )

0 = 4x - 14 ( add 14 to both sides )

14 = 4x ( divide both sides by 4 )

[tex]\frac{14}{4}[/tex] = x , that is

x = [tex]\frac{7}{2}[/tex]

Answer: Okay so let's try to find the amount of money needed to buy 1 lb. Therefore, let's divide the fraction by 14.

Then we'll divide both the numerator and denominator by 14.

÷

Then we simplify and get:

14÷14=1     2.99÷14=.2135   We can round that to .21

The unit rate for each pound would be 1:.21

Answer:

x = -11

Step-by-step explanation:

First, you have to isolate x to one side. To do this, you have to subtract 9 on both sides like this

x + 9 - 9 = -2 - 9

So this will now be

x = -11

There you go!

The question does not seem complete, but I'll represent the statement mathematically and look for their ages each. This is because the worst they can ask for is their ages.

Let C stand for Courtney's age, A for Andrei's age, N for Natalie's age and S for Shari's age. From the question we can deduce the following:

C = 2A

C = N + 3

C = S/2

S - N = C + A

S = 2C, N = C - 3 and A = C/2, therefore we have

2C - (C - 3) = C + C/2

C + 3 = C + C/2

C/2 = 3 and C = 6

A = C/2

A= 6/2

A = 3

N = C - 3

N = 6 - 3

N = 3

S = 2C

S = 2 x 6

S = 12.

C = 6, A = 3, N = 3 and S = 12

As your question is missing some information, so after some research I was able to find the potential question you wanted to ask which is:

Point A is located at negative 4 over 6 and point B is located at negative 1 over 6. What is the distance between points A and B?

So, I am going to answer you based on the complete question I was able to find, which anyways would clear your concept.

Answer:

The distance between A and B will be:  [tex]\frac{3}{6}[/tex]

Step-by-step explanation:

From the question statement, it is clear that

Point A is located at negative 4 over 6 i.e. -4/6, and

point B is located at negative 1 over 6 i.e. -1/6.

As we know that we can determine the distance between two negative numbers on a given line by finding the distance by taking the absolute value of the difference between those numbers.

so,

Distance between A and B will be:

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

                     [tex]=\left|\frac{-4+1}{6}\right|[/tex]

                     [tex]=\left|-\frac{3}{6}\right|[/tex]

                     [tex]=\frac{3}{6}[/tex]

Hence, the distance between A and B will be:  [tex]\frac{3}{6}[/tex]

point A is located at -2, 5

point B is located at 5,5

the distance is 7 units
