Answer:

0 = − 1 /6

Step-by-step explanation:

Answer:

0

Step-by-step explanation:

To find the value of x, we first find the fraction that is equivalent to 1/3 that has a denominator of 12.

Multiplying or dividing the numerator and denominator of

a fraction by the same number will give us an equivalent fraction.

So if we multiply both the numerator and denominator of

the first fraction by 4, we can see that 1/3 = 4/12.

So the value of x must be 4.

Answer:

(- 6, 5 )

Step-by-step explanation:

Substitute x = - 6 into the equation and solve for y

[tex]\frac{2}{3}[/tex] (- 6) + y - 1 = 0 , that is

- 4 + y - 1 = 0

y - 5 = 0 ( add 5 to both sides )

y = 5

Then solution is (- 6, 5 )

Answer: 32.5

Step-by-step explanation: 65 divided by 2 ( 2 x 3 = 6 bring down the 5 so 2x2 = 4. Your remainder is 1 bit you can’t leave it like that so you add a extra zero put your decimal point so 32. (2x5 = 10 (remainder 0)

Answer:

$2511.674254, rounded to $2512

Step-by-step explanation:

1700x1.05^8

The measure of angle QRS is 35 degrees and the measure of angle Q is 116 degrees.

The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

As we know in the triangle the sum of the two interior angles is equal to the exterior angle.

Angle RQS + Angle RSQ = Angle TRQ

4y + y = 145

5y = 145

y = 29

The measure of angle QRS = 180 - Angle RQS - Angle RSQ

= 180 - 4(29) - 29

Angle QRS = 35 degree

The measure of angle Q = 4y = 4(29) = 116 degree

Thus, the measure of angle QRS is 35 degrees and the measure of angle Q is 116 degrees.

Answer: 1/5 of the money

Step-by-step explanation:

The ratio shows that Kyle gets 3 parts of the money, Meg gets 2 parts of the money, and Dan gets 7 parts of the money.  Simple addition lets us know there are 10 parts of the money, and because Meg got 2 of them, she has 2/10ths of the money, or 1/5.

Hope it helps :) and let me know if you want me to elaborate.

Answer:

x = 35/9 or 3 8/9

Step-by-step explanation:

removing the fractions implies using the distributive property, which is multiplying each term outside the parentheses by each term inside

in this problem, after distributing 3/5 we get:

3/5x - 3 = -2/3

we want to isolate the 'x' so we undo subtraction first by adding 3 to each side to get:

3/5x = 9/3 - 2/3

3/5 x = 7/3

x = 7/3 × 5/3

x = 35/9

3/5x = 7/3

we can get the 'x' by itself if we multiply each side by the reciprocal of 3/5, which is 5/3 to get:

x = 7/3 × 5/3

x = 35/3

Answer:

21

Here’s legitimate proof that 9+10=21

(9 + 10) (base x) = 21 (base y)

9(1) + [1(x) + 0(1)] = 2(y) + 1

Simplify and solve for y:

2y = 8 + x

y = 4 + x/2

Since we have number bases, we want x and y to be positive integers. The term x/2 requires that x be a positive even number.

Also since 9 is in base x, we have x ≥ 10, as the digit 9 would not be used for a base 9 or smaller.

Thus we have the pairs of solutions:

x = 10, so y = 9

x = 12, so y = 10

x = 14, so y = 12

…

x, y = 4 + x/2 … Therefore 9+10=21!

To graph a straight line only 2 points are required

although 3 points are better (in case of error with other 2 .)

To find the y-intercept let x = 0 : hence y = - 5 ie (0 , - 5 )

To find the x-intercept let y = 0 : hence -x - 5 = 0 so x = - 5

ie ( - 5 , 0 )

These 2 points will allow the line to be drawn but a 3rd

is preferable. Choose any value for x and evaluate y.

choose x = 2 : then y = - 2 - 5 = - 7 ie (2 , - 7 )

Plot these 3 points: (0 , - 5 ) , (- 5 , 0 ) and (2 , - 7 ) and

draw a straight line through them .

Here is the graph of y = - x - 5
