9. Which of the following equations has NO solution?

A. a + 2 = a + 2
B. a = -a + 2
C. a + 2 = a - 2
D. a + a = 2​

Answer:

x=33

Step-by-step explanation:

subtract 17 from both sides, and then you are left with x=33

Answer:

since they both bisect themselves it means they are equal

i.e 3x=5x-30

3x-5x=-30

-2x=-30

minus cancels minus

2x=30

x=15

Answer:

x = 15

Step-by-step explanation:

3x = 5x - 30

-2x = -30

x = 15

Answer:

2 and 10

Step-by-step explanation:

Answer:

We have to choose 21 strings to be sure we have chosen at least 6 strings of the same type.

Step-by-step explanation:

Since the string type is determined by the initial and terminal bits as understood from the question, then the value of the bits between the initial and terminal bits is of no concern to us.

Now, to be sure you have atleast 6 of the same type, we select each string five times. By doing this, we have already selected 20 strings because we have 4 strings there. Now if you choose any of the string one more time, we are certain that we must have chosen atleast 6 strings that are the same. This means we have to choose 21 strings to be sure we have chosen at least 6 strings of the same type.

Answer:

i pretty sure it's 17

Step-by-step explanation:

Answer:

17

Step-by-step explanation:

Answer:

y=-2x-4

Step-by-step explanation:

Given that,

Slope, m = -2

It passes through the point (1,-6).

We need to find the equation of line that passes throgh the given point. It can be calculated as:

[tex]y-y_1=m(x-x_1)[/tex]

Put y₁ = -6, x₁ = 1 and m = -2

[tex]y-(-6)=(-2)(x-1)\\\\y+6=-2x+2\\\\y+2x+6-2=0\\\\y=-2x-4[/tex]

Hence, the equation of line is y=-2x-4.

Answer:

x>9

Step-by-step explanation:

Remark

You have to watch this question when you divide by a minus. We should try to eliminate that possibility.

Equation

7 - 2/3 x < x - 8             Add 2/3 x to both sides

7 < x + 2/3 x - 8            Combine the like terms on the right.

7 < 1 2/3 x - 8                Add 8 to both sides

7 + 8 < 5/3 x                 Combine the left

15 < 5/3  x                    Multiply both sides by 3/5

15*3/5 < 5/3*3/5 x

9 < x

Since all the answers have the x on the left, we have to put this answer so that x is on the left. Be very careful. The big end of the arrow is towards the x. We have to make sure it stays that way.

x > 9

The answer is A

Answer:

The slides is 36 and the angle is 180.

Step-by-step explanation:

14.4m+15.6m+6m=36

90+30+50=180  

If they ask why it is 180 because when adding all the angles it has to give you a total of 180.

Answer:

[tex] \rm x = \dfrac{2e - 1}{ {e}^{2} } [/tex]

Step-by-step explanation:

[tex] \rm Solve \: for \: x: \\ \rm \longrightarrow ex + {e}^{ - 1} = 2 \\ \\ \rm \longrightarrow e x + \dfrac{1}{e} = 2 \\ \\ \rm Subtract \: \dfrac{1}{e} \: from \: both \: sides: \\ \rm \longrightarrow e x + \dfrac{1}{e} - \dfrac{1}{e} = 2 - \dfrac{1}{e} \\ \\ \rm \longrightarrow ex = \dfrac{2e}{e} - \dfrac{1}{e} \\ \\ \rm \longrightarrow ex = \dfrac{2e - 1}{e} \\ \\ \rm Divide \: both \: sides \: by \: e: \\ \rm \longrightarrow \dfrac{ex}{e} = \dfrac{2e - 1}{e \times e} \\ \\ \rm \longrightarrow x = \dfrac{2e - 1}{ {e}^{2} } [/tex]

Answer:

{-1, 0, 1, 2}

Step-by-step explanation:

Answer:

56x4

Step-by-step explanation:

56x2= 112 so since you have 56x2 twice you want to add 112+112 to get 224 now what you wanna do is to divide 56 from 224 and your answer will be 4 so you can say 56x4

Answer:

= 117/58

Step-by-step explanation:

First of all 1*1 = 1 because a number multiplied by 1 is always itself. We then have to divide 1 by 58 is 0.017  and that +26 is equal to 26.017. Lastly, we have our answer 26.017 or if you wanted it as a fraction 26 1/58!

Answer:%-0.175

Step-by-step explanation: subtract 17.5 percent - 35 percent

Answer:

Cousin has a greater range of score.

Step-by-step explanation:

Range = Highest No. - Lowest No.

Range of cousin's score = +6 - (-2)

                                        = +6+2 = 8

Range of friend's score = -2 - (-3)

                                       = -2 + 3  = 1

Cousin has a greater range of score.

Sentence: it is a set of words that is complete in itself

Answer:

x(x+1)=6​

Step-by-step explanation:

6= 2 numbers, one after the other, so you have the same number and add 1 to make the second number.

Example:

6=2.5 and 3.5

Answer:

X * (x+1) = 6

Step-by-step explanation:

Answer:

7 goals

Step-by-step explanation:

Jimmy scored 49 goals, and Tommy scored 7 times fewer than he did. We now know that an unknown number multiplied by 7 equals 49. This can be represented in an equation:

49/7 = x

x represents the amount of goals Tommy scored. Let's solve our equation to find the answer:

49/7 = 7

7 = x

Tommy scored 7 goals.

12=24x+12

-24x= 12-12

-24x=0

X=24

Answer:

Answer:

The solutions are not viable because the amount of the sale cannot be negative

Step-by-step explanation:

We are told that;

Let A be the amount of the sale in dollars and C be the charge of the online auction

This means that both values of A and B should be non-negative integers.

Now, we are also told that An online auction charges sellers a flat fee of $1.20 and 2% of the amount of the sale.

We can conclude that the solution is not viable because the amount of sale of -1.1 cannot be negative.

Answer:

E (none of the above)

Step-by-step explanation:

1 = k(1.5)

2 = k(3)

Therefore, k = 2/3

and when we put k = 2/3 into all values in the table we notice it is right

but it could be "A" also if the relationship was cups of water to cups of rice

Answer:

The system of equations has one solution at (-4, 4).

Step-by-step explanation:

We are given the system of equations:

[tex]\displaystyle\left \{ {{5x+9y=16} \atop {x+2y=4}} \right.[/tex]

We can use elimination to solve this system. We need to multiply the second equation by -5 so we can cancel out our x-terms.

[tex]-5\times(x+2y=4) \rightarrow -5x - 10y = -20[/tex]

Therefore, our system now becomes:

[tex]\displaystyle\left \{ {{5x+9y=16} \atop {-5x-10y=-20}} \right.[/tex]

Now, we can add these two equations together and solve for y.

[tex]\displaystyle(5x + 9y) + (-5x - 10y) = 0 - y\\\\16 + (-20) = -4\\\\-y = -4\\\\\frac{-y}{-1}=\frac{-4}{-1}\\\\y = 4[/tex]

Now, we can substitute our value for y into one of the equations and solve for x.

[tex]x+2(4)=4\\\\x + 8 = 4\\\\x = -4[/tex]

Therefore, our final solution is (-4, 4).
