Omar has $300 in his savings account and deposits $20 each week. His brother has $600 in his savings account, but he withdraws $30 each week. After how many weeks will they have the same amount?

Answer:

1. 5, 11, 18, 26, 35, 45

Step-by-step explanation:

5, 11, 18, 26,

The difference between 5 and 11 is 6.

The difference between 11 and 18 is 7.

The difference between 18 and 26 is 8.

As you can see their difference increases by 1, so the next difference would be 8 + 1 = 9.

26 + 9 = 35

And the next difference would be 9 + 1 = 10.

35 + 10 = 45

Answer: 7 - (-5)+12

Step-by-step explanation: best I can put it

(-5) - (-12) = 7 . Option b,c, and d are correct.

Subtraction is a mathematical operator which gives diffrence between two numbers.

Given expression is,  (-5) - (-12)

                                 = -5 +12

                                 = 7

Absolute difference between -5 and -12 is equal to 7.

And, absolute difference between -12 and -5 is equal to 7.    

Also,                          (-5) + 12 = 7  

Hence, expressions with value = 7 are correct.

Answer:

  A.  y = 2/3x - 2

Step-by-step explanation:

The line intersects the y-axis at -2, so eliminates choices B and D, which have y-intercepts of +3.

The line has a rise of 2 grid squares for a run of 3 grid squares, so has a slope of ...

  m = rise/run = 2/3 . . . . . eliminates choice C

The appropriate choice is the one with a slope of 2/3 and a y-intercept of -2:

  A.  y = 2/3x - 2

Answer:

Casey's Function has the greater rate of change

Step-by-step explanation:

The graph shows a ROC of 5/1

Get a common denominator (4)

5/1 * 4/4 = 20/4

20/4 > 13/4

Casey's function has a greater ROC.

Answer:

400 red boxes were sold

Step-by-step explanation:

Step 1: Our output value is 2000.

Step 2: We represent the unknown value with x.

Step 3: From step 1 above,2000=100%.

Step 4: Similarly, x=40%.

Step 5: This results in a pair of simple equations:

2000=100%

x=40%(2)

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

2000/x = 100%/40%

Step 7: Again, the reciprocal of both sides gives

x/2000 = 40%/100%

x=800

Therefore, 40% of 2000 is 800

and to find 50% just divide by 2

Given:

The equation of line is

[tex]y=x+3[/tex]

To find:

The x-intercept and y-intercept.

Solution:

The equation of line is

[tex]y=x+3[/tex]

Putting x=0, we get

[tex]y=0+3[/tex]

[tex]y=3[/tex]

So, the y-intercept is (0,3).

Putting y=0 in the given equation, we get

[tex]0=x+3[/tex]

[tex]-3=x[/tex]

So, the y-intercept is (-3,0).

Therefore, the coordinates of the point where the line intersects the y-axis are (0,3). The coordinates of the point where the line intersects the x-axis are (-3,0).

Step-by-step explanation:

There are several ways to solve this problem, but I think the easiest way is just to find the mean.

There are 12 total data points, and adding them all up you get 266.

mean = 266/12 = 22.167

The line in the middle of the box plot represents the mean, so the answer must be B.

Answer:

The values of [tex]x[/tex] and [tex]y[/tex] are 10 and 14, respectively.

Step-by-step explanation:

According to the figure, we notice that [tex]AB\equiv BC\equiv AC[/tex] and [tex]\angle A \equiv \angle B\equiv \angle C[/tex], concluding that such triangle is equilateral. Since the sum of internal angles within triangle is equal to 180º, then:

[tex]m \angle A = m \angle B = m \angle C = 60^{\circ}[/tex] (1)

If we know that [tex]m\angle A = 6\cdot x[/tex], then the value of [tex]x[/tex] is:

[tex]6\cdot x = 60^{\circ}[/tex]

[tex]x = 10[/tex]

If we know that [tex]AC = 14[/tex] and [tex]AB = y[/tex], then the value of [tex]y[/tex] is:

[tex]y = 14[/tex]

The values of [tex]x[/tex] and [tex]y[/tex] are 10 and 14, respectively.
