Answer: Allison owes the bank more then $50

Answer:

Allison will need more than $50.

Step-by-step explanation:

If you add 50 to -50.15, there is still -.15 cence left. So Allison will need more than $50 to have a positive balance.

Marbles:

5 red

3 green

4 yellow

Total marbles = 5 + 3 + 4 = 12.  

The probability of picking a green marble is 3/12, since there are 3 green marbles possible to grab and 12 total.  3/12 can be reduced to 1/4, or .25.  Devon has a 25% chance of picking a green marble.

Step-by-step explanation:

Hi there! Your answer is x = -2, y = -9/2

In coordinate point, we can write (-2,-9/2)

Please see the explanation below for a clear understand about the problem.

Any questions about the answer, feel free to ask in comment! :)

Step-by-step explanation:

Goal

Given

[tex]\begin{cases} x=2y+7 \Longrightarrow (1)\\ 3x-2y=3 \Longrightarrow (2) \end{cases}[/tex]

Step 1

Substitute x = 2y+7 in the second equation.

[tex]3x-2y=3\\3(2y+7)-2y=3[/tex]

We do this so we can solve for the y-term without any problems. (We need to get rid of a variable if there are more than one variable.)

Then we distribute/expand 3 in the expression.

[tex]6y+21-2y=3\\4y+21=3[/tex]

Step 2

To solve the equation, we have to isolate the term that we want. For this scenario, we want to know the value of y-term. Therefore, we isolate y-term.

[tex]4y=3-21\\4y=-18\\y=-\frac{18}{4} \\y=-\frac{9}{2}[/tex]

Finally! we know the value of y which is -9/2. But we are not done yet!

Step 3

After we solve the equation, we have to substitute the value in any given equations. No need to substitute the value in both equations! Choose an equation to substitute the value in.

For this, I will be choosing an equation with less coefficients which is the first equation.

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

Substitute y = -9/2 in the equation.

[tex]x=2(-\frac{9}{2})+7\\x=-9+7\\x=-2[/tex]

We should get x = -2 as the answer. This is our last step for finding an answer. The next few steps are going to be how to check the answer for system of equations. Note that next few steps are optional. If you are not certain that the answer is wrong or right, it is highly advised to check the answer before jumping to a conclusion!

Optional Steps - Answer Check

To check the answer, we can simply substitute both x-value and y-value in any given equations. You can either choose only a single equation to substitute in ONLY if you are certain/sure that the answer is likely correct. Substituting in both equations are recommended for beginners.

Step 3

Step 3.1

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

From x = -2 and y = -9/2

[tex]-2=2(-\frac{9}{2} )+7[/tex]

Cancel 2 out.

[tex]-2=-9+7\\-2=-2[/tex]

As you can see, both sides are equal. That means the equation is true for x = -2 and y = -9/2.

Step 3.2

[tex]3x-2y=3[/tex]

Substitute x = -2 and y = -9/2 in the equation.

[tex]3(-2)-2(-\frac{9}{2})=3\\-6+\frac{18}{2}=3\\-6+9=3\\3=3[/tex]

Since both equations are true for x = -2 and y = -9/4. We can conclude that:

[tex]\huge\sf{x = -2 \ and \ y = -\frac{9}{2} \ are \ the \ solutions \ to \ the \ system \ of \ equations.}[/tex]

Hence, the answer is x = -2 and y = -9/2.

Answer:

A -1

Step-by-step explanation:

The coefficient is the number in front of a variable. since there isn't a number we can conclude that the y is only there once. There is 1 (one) y. Since it is subtracting in front of the coefficient, we can determine it is taking one away, or -1. So 6-y+3 is 6-1y+3.

Answer:

Mr Doyle washed the most.

4/15 still need to be washed.

Step-by-step explanation:

2/5=6/15  Mr Doyle

1/3=5/15   Son

so Mr Doyle washed the most.

Together they washed 11/15 of the laundry so 4/15 is left to wash.

Answer: 10!

Step-by-step explanation:

Answer:

9

Step-by-step explanation:

Both sides are going to be exactly the same angle. So if its 35° on the right it will be 35° on the left also.

[tex](3x + 8)[/tex]

[tex](3 \times 9 + 8)[/tex]

9 goes into where X was

[tex]3 \times 9 = 27[/tex]

[tex]27 + 8 = 35[/tex]

[tex](3 \times 9 + 8 ) = 35[/tex]

Step-by-step explanation:

Answer:

Step-by-step explanation:

No, in order for a set of numbers to be a function, it has to pass the vertical line test. Draw a vertical line to see if it intersects the line more than once. Another way to think about it, is that one singular x value cannot give two different y values. That is impossible.

For example at x = 0, there are two y values that relate to that point. I'm going to estimate the y value for simplicity and the purpose of explanation.

Step-by-step explanation:

10x9x8x7 = 5,040

Using the permutation formula, it is found that 5040 passwords are possible.

The order is important, as 1234 is a different password than 2134, for example, hence the permutation formula is used to solve this question.

The number of possible permutations of x elements from a set of n elements is given by:

[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]

In this problem, 4 digits are taken from a set of 10, hence:

[tex]P_{(10,4)} = \frac{10!}{6!} = 5040[/tex]

5040 passwords are possible.

Answer:

  3380 miles

Step-by-step explanation:

The distance separating the planes can be found using the law of cosines. One plane has gone 3×700 = 2100 miles; the other has gone 3×895 = 2685 miles. The angle between their flight paths is 46°+43° = 89°. Then the separation (s) is ...

  s² = 2100² +2685² -2(2100)(2685)cos(89°) = 11,619,225 -11,277,000×0.01745

  s² ≈ 11,422,414.21

  s ≈ √11,422,414.21 ≈ 3379.7

The planes are separated by about 3380 miles after 3 hours.

The experimental probability of spinning a green will be 0.10 or 10%.

Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.

Then the probability is given as,

P = (Favorable event) / (Total event)

Philip spun a spinner with six sections 125 times and the results are shown in the table.

Color               Frequency

Blue                       25

Green                     15

Purple                    23

Yellow                    22

Red                         21

Pink                         19

The experimental probability of spinning a green will be given as,

P = 15 / 150

P = 0.10 or 10%
