Answer:

Step-by-step explanation:

how can a+b=0?

is a+b=0 a single word followed by the question mark ? the sentence is not complete if “a+b=0” is the subject, it’s like: how can cat?

is the sentence rather: how can a+b be equal to 0 ( meaning zero) ? in that case, supposing we are talking of the usual sum of two elements of an additive group : how can the sum of a and b, written a+b, can be equal to zero, then this seems more like a question about what powers do have any two elements of a group to, by association through addition, to obtain a zero value. Like “how can my brother and me get one of these chocolates ?”

Now, in your question, maybe a and b are not any two elements of said group but elements well identified before,

suppose you know a is 1 and b is -1 for instance. Then how can 1–1=0? is a very good question : it marvels at the fact that the addition does what it is supposed to do. Lots of things don’t, and lots of people take it for granted that things do what they are supposed to de, like speeds add up, etc.

let’s suppose for example, a is 1 and b is 2.

Then your question is very justified : how can 1+2 be equal to 0 ? it’s a scandal, either the computer is broken, or my mind is , and if anywhere in the world 1+2 =0, there is something wrong with the world.

Answer:

morning - 40

afternoon - 85

Step-by-step explanation:

The bus traveled 40 miles in the morning and 85 miles in the afternoon.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The school bus traveled five miles more on a field trip in the afternoon than it did in the morning. If the journey was 125 kilometers long

Let x the distance traveled by bus in the morning.

As per the given condition, we can get the equation shown below:

⇒ x + 2x + 5 = 125

⇒ 3x + 5 = 125

⇒ 3x = 120

⇒ x = 40

In the afternoon, the bus traveled 2x + 5 miles.

Now substitute the value of x in the equation for the afternoon miles to include:

⇒ 2 × 40 +5 = 85

Therefore, the bus traveled 40 miles in the morning and 85 miles in the afternoon.

Answer:

$17.82

Step-by-step explanation:

[tex]125.05 - 28.35 = 96.7 \\ 96.7 - 78.88 = 17.82[/tex]

Answer: $232.48

Step-by-step explanation: an equation you could use would be:

125.25+(28.35+78.88)

Add parentheses: 28.35+78.88= 107.23

Answer:

[tex]x=2y+6[/tex]

Step-by-step explanation:

So we have the system:

[tex]-x+2y=-6\\3x+y=8[/tex]

If we isolate the x-variable in the first equation:

[tex]-x+2y=-6[/tex]

Subtract 2y from both sides:

[tex]-x=-6-2y[/tex]

Divide both sides by -1:

[tex]x=2y+6[/tex]

Therefore, we would substitute the above into the second equation:

[tex]3x+y=8\\3(2y+6)+y=8[/tex]

The answer is 2y+6

Further notes:

To solve for the system, distribute:

[tex]6y+18+y=8[/tex]

Simplify:

[tex]7y+18=8[/tex]

Subtract:

[tex]7y=-10[/tex]

Divide:

[tex]y=-10/7\approx-1.4286[/tex]

Now, substitute this value back into the isolated equation:

[tex]x=2(-10/7)+6\\x=-20/7+42/7\\x=22/7\approx3.1429[/tex]

Step-by-step explanation:

Start by solving the equation for x (☓)

[tex] - x + 2y = 6 \\ \: \: \: \: \: 3 + y = 8[/tex]

[tex]x = 6 + 2y[/tex]

[tex]3(6 + 2y) + y = 8[/tex]

[tex]y = - \frac{10}{7} [/tex]

[tex]x = 6 + 2 \times ( - \frac{10}{7} )[/tex]

[tex]x = \frac{22}{7} [/tex]

Answer:

end point of a segment  X₂ = - 8 ;  Y₂ = 21

Step-by-step explanation:

given;

midpoint = ( Mx = -4 , My = 13 )

endpoint ₁  = ( X₁ = 0 ,  Y₁ = 5 )

find the other endpoint ₂ ( X₂ , Y₂)

use the mid point formula to get the other endpoint:

Mx = ( X₁ + X₂ ) / 2              My = ( Y₁ + Y₂ ) / 2

- 4 = (0 + X₂) / 2                 13 = (5 + Y₂) / 2

-8 = 0 + X₂                         26 = 5 + Y₂

X₂ = -8                                    Y₂ = 21

Step-by-step explanation:

first convert feet to inches because the measure of cubes is in inches

( 12 inches=1 foot)

9 ft = 12*9=108 inches

8 ft=12*8=96 inches

7 ft= 12*7=84

the volume of the one cube= 5*5*5=125

volume of the classroom: 108*96*84=870912

The which function has an inverse that is a function is m(x) = -7x

let f be a Function. If any horizontal line intersects the graph of f extra than once, then f does now not have an inverse. If no horizontal line intersects the graph of f greater than once, then f does have an inverse. The belongings of getting an inverse may be very vital in arithmetic, and it has a call.

Answer:

15.71 ft

Step-by-step explanation:

Given that:

width of the circular track = 2.5ft

Suppose the radius of the inner circle is 57 ft since it is not given

Then the radius of the outer circle = (2.5 + 57) ft = 59.5 ft

The circumference of a circle = 2πr

For inner circle now, the circumference = 2 × π × 57 ft

For inner circle now, the circumference = 358.14 ft

For the outer circle, the circumference = 2 × π × 59.5 ft

For the outer circle, the circumference = 373.85 ft

The difference between the circumference of the outer wheel from the inner wheel shows how farther does a wheel on the outer rail travel than a wheel on the inner rail of the track in one​ turn

∴

= ( 373.85 - 358.14 ) ft

= 15.71 ft

Answer:

1. The two numbers are 56 and 15

2. The two angles are 56 and 34 degrees

3. The two angles are 110 and 70 degrees

4.The largest number is -10

Step-by-step explanation:

Solving (1):

Represent both numbers with x and y

[tex]x = 11 + 3y[/tex]

[tex]x + y = 71[/tex]

Solving for x and y

Substitute [tex]11 + 3y[/tex] for x in the second equation

[tex]11 + 3y + y = 71[/tex]

Collect Like Terms

[tex]3y + y =71 - 11[/tex]

[tex]4y = 60[/tex]

Divide both sides by 4

[tex]y = 15[/tex]

Recall that

[tex]x = 11 + 3y[/tex]

[tex]x = 11 + 3 * 15[/tex]

[tex]x = 56[/tex]

Hence, the two numbers are 56 and 15

Solving (2)

Represent the two angles with x and y

[tex]x = 22 + y[/tex]

Since they are complementary;

[tex]x + y = 90[/tex]

Substitute 22 + y for x in [tex]x + y = 90[/tex]

[tex]22 + y +y= 90[/tex]

[tex]22 + 2y =9 0[/tex]

Collect Like Terms

[tex]2y = 90 - 22[/tex]

[tex]2y = 68[/tex]

Divide both sides by 2

[tex]y = 34[/tex]

Recall that [tex]x = 22 + y[/tex]

[tex]x = 22 + 34[/tex]

[tex]x = 56[/tex]

Solving (3):

Represent the two angles with x and y

[tex]x = 40 + y[/tex]

Since they are supplementary;

[tex]x + y = 180[/tex]

Substitute 40 + y for x in [tex]x + y = 180[/tex]

[tex]40 + y + y = 180[/tex]

[tex]40 + 2y = 180[/tex]

Collect Like Terms

[tex]2y = 180 - 40[/tex]

[tex]2y = 140[/tex]

Divide both sides by 2

[tex]y = 70[/tex]

Recall that [tex]x = 40 + y[/tex]

[tex]x = 40 + 70[/tex]

[tex]x = 110[/tex]

Solving (4):

Let the smallest number be x

[tex]x + x + 2 + x + 4 = -36[/tex]

Collect Like Terms

[tex]x + x + x = -36 - 2 - 4[/tex]

[tex]3x =-42[/tex]

Divide through by 3

[tex]x = -14[/tex]

The largest number; x + 4 is

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

[tex]x + 4 = -10[/tex]

Hence, the largest number is -10

Explanation:

Going from figure (1) to figure (2) has us rotate 90 degrees counterclockwise. Note the smallest side of the green figure how it is horizontal, and it corresponds to the smallest side of the blue figure and it is vertical. The center of rotation is the top right corner of the green figure.

Then we apply a translation to go from figure (2) to figure (3). This is another way of saying we shifted the figure some distance left/right and up/down. In this case, we shifted 1 unit to the right and 4 units down.
