Answer:

Step-by-step explanation:

2(-3/5) = -6/5. (2)*(-3) = - 6/5

- 6/5 - 1/3 = 23/15. (Common denominator = 15)

6/15 - 5/15 = - 23/15

(- 23/15) / ( -6.75 / 15) = 92/27 = 3 11/27

Answer:

Zero solutions

Step-by-step explanation:

When you simplify the equation you get that 4x+2=4x+3. That is not equal so therefore it has zero solutions

Answer:

The only solution could be is if u had x as a variable, if not then you don't have a solution because you won't know what x is.

Answer:

The negative sign outside the absolute value function causes a few different things when multiplied. When a negative is multiplied outside of the function, the transformation that exists will be a vertical reflection.  A horizontal shift to the left 1 unit will happen because of g(x)=f(x+1). The graph will make a vertical shift down 2 units because of g(x)=f(x)−2. The value of (a) would be -1 and since it is less than 1, and it causes the graph to be wider because of vertical compression. Placing a minus sign outside absolute value bars gives you a negative result.

Answer:

as line L is parallel to m

angle pqt = 89° ( vertically opposite angle)

angle tpq = 3x° ( vertically opposite angles).

in triangle pqt

angle p + angle q + angle t = 180° (angle sum proper of a triangle)

Let the unknown angle ptq be X

3x + 89 + X = 180°

3x + x + 89 = 180

4x + 89 = 180

4x = 180 - 89

4x = 91

x = 27°

angle u = 89° ( corresponding angles)

angle ptu = 89 + 27

= 116°

The probability that the technician arrives exactly at 4:00 pm is 1/5.

Probability is the chance of occurring a certain event out of the total no. of events that can occur in a given context. The probability of an event is always greater than equal to zero and less than equal to one.

If we distribute arrival time uniformly in terms of hours the no. of sample space N(s) = 5.     (3:00pm, 4:00pm, 5:00pm, 6:00pm, 7:00pm).

∴ The probability that he arrives exactly at 4:00 pm is,

Answer:

660.4 mm

Step-by-step explanation:

Since 1 inch is equal to 25.4 millimeters, we can multiply 25.4 by 26 to see how many millimeters 26 inches is. You can also think of this as a proportion:

26:x = 1:25.4

26.4 times 26 is equivalent to 660.4, so we can conclude that 26 inches are equivalent to 660.4 millimeters.

Answer:

3x + y = - 9

Step-by-step explanation:

y - 6 = -3 (x + 5)

Distribute the -3

y - 6 = -3x - 15

Add 3x to both sides

3x + y - 6 = -15

Add 6 to both sides

3x + y = - 9

Answer:

a) 22,500  b) 2250 seconds (or 37.5 minutes)

Step-by-step explanation:

a) There are 1000 ml in a liter.

Therefore, the rate of water flowing in can be 3000 ml per minute. To convert this into per second, we divide 3000 by 60.

This becomes 50 ml per second. If the tank fills in completely in 450 seconds,  we multiply 50 by 450 to get how much water in ml was used to fill the tank completely. 50 times 450 = 22,500. Therefore, the capacity of the tank is 22,500.

b) Since water keeps flowing into the tank at a rate of 50 ml per second, and water flows out at a rate of 60 ml per second, we can define the rate flowing out of the tank as 10 ml per second.

Because the maximum capacity of the tank is 22,500 ml, we divide this by 10 ml (the rate flowing out) to get how many seconds it will take for the tank to drain out completely. 22,500 divided by 10 is 2250.

So, it will take 2250 seconds for the tank to drain completely. In minutes, this becomes 37.5 minutes.

Step-by-step explanation:

Answer:

x = 2

y = 1

Step-by-step explanation:

1) Re-arrange

(Solving for y)

-2x -3y = -7    -->  x3

6x - y = 11    -->  x1

-6x -9y = -21

6x -y = 11

-9y = -21

-y = 11

(-9y + -y) = (-21 + 11)

-10y = -10    

y = -10/-10

y = 1

2) Substitute

6x - 1 = 11

6x = 11 + 1

6x = 12

x = 12/6

x = 2

Answer: x = 2, y = 1

Step-by-step explanation:

Rearrange the second equation so it just works a little easier for you:

-2x - 3y = -7

rearranged to make y (with its constant) the subject:

3y = 7 - 2x

So we know what y equals. The question tells us y = 6x - 11. So substitute those values into the rearranged equation.

3y = 7 - 2x   becomes:

3(6x - 11) = 7 - 2x

because as stated in the question, y = 3x - 11.

Expand the brackets on the left-hand side:

18x - 33 = 7 - 2x

Rearrange to collect like terms:

18x = 7 + 33 - 2x

18x = 40 - 2x

18x + 2x = 40

20x = 40

x = 40/20

x = 2.

So now we know the value of x.

Let's input our new found value of x into one of the given equations, such as y = 6x - 11.

y = (6 * 2) - 11

y = 12 - 11

y = 1.

So y = 1.

You can test this by inputting these values into the other equation, for assurance.

-2x - 3y = -7 becomes:

(-2 * 2) - (3 * 1) = -7

(-4) - 3 = -7

-7 = -7

  b) 62

Step-by-step explanation:

When all the numbers are in scientific notation, as these are, the numbers with the smallest exponent are smaller. If numbers have the same exponent, the number with the smaller mantissa is smaller.

a) least-to-greatest diameter, the order is ...

  Pluto, Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn, Jupiter

__

b) The ratio of diameters of Jupiter and Pluto is ...

  (1.43×10^8)/(2.3×10^6) = 6.2×10^1 = 62

Jupiter's diameter is about 62 times that of Pluto.

Step-by-step explanation:

Answer:

[tex]5 \sqrt{2} [/tex]

Step-by-step explanation:

the equation is

y = ax + b

a is the slope of the line. this is the ratio y/x indicating how many units y changes, when x changes a certain number of units.

so, when we go from A to B, x changes 2 units (from 3 to 5), and y changes -4 units (from 5 to 1).

so the slope is -4/2 = -2

now or equation looks like

y = -2x + b

to get b we use one of the points in the equation. e.g. B

1 = -2×5 + b = -10 + b

b = 11

so, our full equation is

y = -2x + 11

Answer:

Step-by-step explanation:

There are two ways you can divide 2/3 by 1/6.

1) Division by a number is the same as multiplication by its reciprocal. The reciprocal of a fraction is the fraction obtained by swapping the numerator and denominator. So, division by 1/6 is the same as multiplication by 6/1.

  2/3 ÷ 1/6 = 2/3 × 6/1

The result of this multiplication is the product of the numerators divided by the product of the denominators:

  2/3 × 6/1 = (2×6)/(3×1) = 12/3 = 4

__

2) The fractions can be expressed with the same denominator. Then their quotient is the quotient of their numerators.

  2/3 = 4/6

  2/3 ÷ 1/6 = 4/6 ÷ 1/6 = 4 ÷ 1 = 4
