Two numbers have a sum of 24 and a difference of 5. Use and algebraic method to find the two numbers.

Answers

Step-by-step explanation:

x, y are the 2 numbers

x + y = 24

x - y = 5

x = y + 5

and that in the first equation

y + 5 + y = 24

2y = 19

y = 9.5

x = y + 5 = 9.5 + 5 = 14.5

the 2 numbers are 9.5 and 14.5.

9z - 3x

Answers

Answer:

x = 1.27

y = 5.18

Step-by-step explanation:

to solve this system of  equation by simultaneous equation we say that let

3x+y=9.............................. equation 1

-5x+2y=4 .......................... equation 2

from equation 1

3x+y=9.............................. equation 1

y = 9 -3x.............................. equation 3

substitute the value of y = 9 -3x into equation 2

-5x+2y=4 .......................... equation 2

-5x + 2( 9 -3x) = 4

-5x + 18 - 6x = 4

collect the like terms

18 - 4 = 6x + 5x

14 = 11x

divide both side by 11

14/11 = 11x/11

x = 14/11

x = 1.27

put the value of x = 1.27 into  equation 3

y = 9 -3x.............................. equation 3

y = 9 - 3( 1.27)

y = 9 - 3.82

y = 5.18

to check if you are correct put the value of x and y into either equation 1 or equation 2.

3x+y=9.............................. equation 1

3( 1.27) + 5.18 = 9

3.81 + 5.18 = 9

9 = 9

The power, P(watts), of a car engine is proportional to the square of its speed, s(m/s).
When s=45 P=2200.
Work out the speed (to 1 DP) when the power is 1890 watts

Answers

The speed of the car is 41.7 m/s when the power is 1890 watts.

What is Proportion?

Proportion is defined as an equation on which two or more ratios are made to be equal to each other.

It is given that the power, P is proportional to square of the Speed,s.

If P ∝ s², then P = k s², for some constant k.

When s = 45 m/s, P = 2200 watts

k = P / s² = 2200 / 45² = 1.086

∴ when P = 1890 watts,

1890 = 1.086 × s²

s² = 1740.331

s = 41.717 ≈ 41.7 m/s

Hence, if power is proportional to the square of the speed, then, the speed of the car engine is 41.7 m/s if the power is 1890 watts.

299 divided by 21 step by step

Answers

Step 1:
Start by setting it up with the divisor 21 on the left side and the dividend 299 on the right side like this:

2 1 ⟌ 2 9 9

Step 2:
The divisor (21) goes into the first digit of the dividend (2), 0 time(s). Therefore, put 0 on top:

0
2 1 ⟌ 2 9 9

Step 3:
Multiply the divisor by the result in the previous step (21 x 0 = 0) and write that answer below the dividend.

0
2 1 ⟌ 2 9 9
0

Step 4:
Subtract the result in the previous step from the first digit of the dividend (2 - 0 = 2) and write the answer below.

0
2 1 ⟌ 2 9 9
- 0
2

Step 5:
Move down the 2nd digit of the dividend (9) like this:

0
2 1 ⟌ 2 9 9
- 0
2 9

Step 6:
The divisor (21) goes into the bottom number (29), 1 time(s). Therefore, put 1 on top:

0 1
2 1 ⟌ 2 9 9
- 0
2 9

Step 7:
Multiply the divisor by the result in the previous step (21 x 1 = 21) and write that answer at the bottom:

0 1
2 1 ⟌ 2 9 9
- 0
2 9
2 1

Step 8:
Subtract the result in the previous step from the number written above it. (29 - 21 = 8) and write the answer at the bottom.

0 1
2 1 ⟌ 2 9 9
- 0
2 9
- 2 1
8

Step 9:
Move down the last digit of the dividend (9) like this:

0 1
2 1 ⟌ 2 9 9
- 0
2 9
- 2 1
8 9

Step 10:
The divisor (21) goes into the bottom number (89), 4 time(s). Therefore put 4 on top:

0 1 4
2 1 ⟌ 2 9 9
- 0
2 9
- 2 1
8 9

Step 11:
Multiply the divisor by the result in the previous step (21 x 4 = 84) and write the answer at the bottom:

0 1 4
2 1 ⟌ 2 9 9
- 0
2 9
- 2 1
8 9
8 4

Step 12:
Subtract the result in the previous step from the number written above it. (89 - 84 = 5) and write the answer at the bottom.

0 1 4
2 1 ⟌ 2 9 9
- 0
2 9
- 2 1
8 9
- 8 4
5

You are done, because there are no more digits to move down from the dividend.

The answer is the top number and the remainder is the bottom number.

Therefore, the answer to 299 divided by 21 calculated using Long Division is:

PRODUCT of the factors must equal......

Answers

Answer:

  10. (-1, 7), (-7, 1)

  11.  (8, 4), (16, 2)

Step-by-step explanation:

10.

Let x and y represent the two missing factors. Then you have ...

  -3xy = 21

  xy = -7 . . . . . . . divide by -3

Integer divisors of -7 are ±1, ±7, so possible factor pairs are (-1, 7), (-7, 1) and their reverse.

Of course, the only requirement is that the values be rational, so we could have (-1/4, 28), for example. One of the above factors can be multiplied by any rational number, and the other multiplied by its inverse.

__

11.

If the two factors of interest are x and y, then the product of the three factors is ...

  (-3/4)xy = -24

  xy = (-4/3)(-24) = 32

Integer divisors of 32 are 1, 2, 4, 8, 16, 32. So, any of those, positive or negative, could be one of the (integer) factors you're looking for. On the attached graph, we have shown (x, y) pairs ...

  (8, 4), (16, 2), (-4, -8)

There are an infinite number of possibilities.

Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6.Step-by-step

-2 and 21/50

Step-by-step explanation:

PEMDAS says that paranthases go first, so we solve 2 and 1/5 minus 33/12. 2 and 1/5 simplifies to the improper fraction, 11/5. Then we find a common denominater between 11/5 and 33/12 to get 60. 11/5=132/60, and 33/12=165/60. (132/60)-(165/60)=-33/60. Then we multipl that by 4 and 2/5, which can simplify to the improper fraction, 22/5. (22/5)*(-33/60) is -726/300, and simplifies to -2 and 21/50. Hope this helps!
