: 3x + y = 9

y = 9 - 3x

x - 2y = 10

y = (x - 10)/2

2(9 - 3x) = x - 10

18 - 6x = x - 10

7x = 28

x = 4

y = 9 - 3(4)

y = 9 - 12

y = - 3

Answer: x = 4, y = - 3

Proof—2nd equation:

4 - 2(- 3) = 10

4 + 6 = 10

Hope this helps :)

y = 9 - 3x

x - 2y = 10

y = (x - 10)/2

2(9 - 3x) = x - 10

18 - 6x = x - 10

7x = 28

x = 4

y = 9 - 3(4)

y = 9 - 12

y = - 3

Answer: x = 4, y = - 3

QUESTION POSTED AT 06/12/2019 - 01:33 PM

both variables are x

pretend there is an imaginary 1 in front of the x for x squared

3 x 1 = 3

x^2 x X = x^3

this is because when multiplying numbers with the same variable like this problem for instance then you add the squared (2) with the x ( imaginary 1)

so 3x^3 is the answer

**Answer:**

**We need the use of square root** because it helps us to find the square root of a number, you want to find some number that when multiplied by itself gives you the original number.

or In other words, you can find the square root of 36, you want to find the number that when multiplied by itself gives you 36.

therefore, the square root of 36 is 6 [as ]

Also, the symbol for square root is .

**We need the use of cube root, **to find the cube root of a number, you want to find some number that when multiplied by itself twice gives you the original number.

or in other word, you can find the cube root of 64, you want to find the number that when multiplied by itself twice gives you 64.

therefore, the cube root of 64 is 4. { as }

**The symbol of cube root is denoted as**

The values given is not sufficient.

However, the rates could 18/2n or 90/10n

In essence, rate is comparison between ratios. While ratio is comparison between two or more numbers. Further, ratio on one hand, involves numbers either in amount, size, measurement, degrees, percentages or fractions with the absence of specific unit of measurement. On the contrary, rate is comparing quantities, amounts or unit of events happened expressed in a specific measurement or expressed under time. Take for instance, an example, Joe eats 2 while John eats 4 meals in a day. The ratio can be Joe: John, 2:4 meals. While the rate, is Joe eats 2 meals/day and John 4 meals/day.

The *correct answer* is:

C.) 0.00140 kiloliters

**Explanation**:

To convert this, we can use a metric conversion chart:

Kilo- Hecto- Deca- base deci- centi- milli-

Starting with 140 centiliters, converting to deciliters moves to the left 1 place; this moves the decimal to the left one, making it 14.0 deciliters.

Converting to liters, we move to the left 2 places; this moves the decimal to the left two, making it 1.40 liters.

Converting to milliliters, we move to the right 1 place; this moves the decimal to the right one, making it 1400 milliliters.

Converting to kiloliters, we move to the left 5 places; this moves the decimal left 5, making it 0.00140 kiloliters.

17x - 6 + 3x - 5 = x + 11 + 4x

The first thing to do is to get all the xs on the same side.

17x + 3x - x - 4x = 11 + 5 + 6

15x = 22

x = 22/15

The answer is x = 22/15

22 - 15 = 7

If this needs to be simplified, the answer is x = 1 7/15
