Answer:

32 : 24 is smaller

Step-by-step explanation:

32 : 24 = 32/56, reduced is 4/7

30 : 22 = 30/52, reduced is 15/26

a common denominator is 182:

4/7 = 104/182

15/26 = 105/182

Step-by-step explanation:

Answer:

10x - 12y = 192

Step-by-step explanation:

Given the equation :

-5/8x + 3/4y = 12 - - - (1)

8x + 12y = 11 ___(2)

The equivalent form of the first equation which can eliminate the y term :

Multiply (1) by - 16 :

-5/8x * - 16 + 3/4y * - 16 = 12 * - 16

10x - 12y = 192

Hence, Adding the obtained equation and equation(2) will eliminate.

Answer:

Step-by-step explanation:

Part A:

Mark did not round to the nearest hundreds, he rounded to the nearest tens.

Option A (Incorrect):

271 and 582 are normally not rounded down, unless we are using limits coming from the left and a unique equation.

Option B (Incorrect):

271 as the same problem as option A, but 582 rounding to 600 is correct. It doesn't make sense to round both numbers differently, unless stated.

Option C (Incorrect):

271 rounding to 300 is correct, but 582 is not normally rounded down to 500 unless we are using limits coming from the left and a unique equation. Unless stated, don't round both numbers differently.

Option D (Correct):

271 rounded to 300 and 582 rounded to 600 looks correct for rounding to the hundreds.

Part B:

There are two ways to solve this question:

One way:

271 + 582 = 853

Round 853 to the nearest hundred for 900

(Note: Round 853 to the nearest tens for 850.)

Second way:

271 + 582

Round Numbers:

300 + 600

= 900

Since the square root of a negative number isn't a real number, this problem has no real solutions. The answer is [There are no real solutions to the system]

Answer:

G(x)=2/15x-6

Step-by-step explanation:

The linear function graphed on the grid will be g(x) = (15/2) x + 45. Then the correct option is D.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

x/a + y/b = 1

Where 'a' is the x-intercept of the line and ‘b’ is the y-intercept of the line.

From the graph, the x-intercept is - 6, and the y-intercept is 45. Then the equation is given as,

x/(-6) + y/45 = 1

- 15x + 2y = 90

y = (15/2) x + 45

g(x) = (15/2) x + 45

The linear function graphed on the grid will be g(x) = (15/2) x + 45. Then the correct option is D.

Answer:

The measure of the angle subtended by each arc intercepted by the sides of the reh13-gon is approximately 27.69°

Step-by-step explanation:

The number of of equal sides in a regular 13-gon = 13 sides

The measure of the angle, 'θ', subtended by each arc intercepted by the sides of the 13-gon is given as follows;

θ = 360°/13 = [tex]27\dfrac{9}{13} ^{\circ}[/tex]  

By rounding rounding the answer to the nearest 10th, we have that the measure of the angle subtended by each arc intercepted by the sides of the 13-gon, θ = [tex]27\dfrac{9}{13} ^{\circ}[/tex] ≈ 27.69°

You're answer is c 55/6.

Answer:

C. 55/6

Step-by-step explanation:

It’s 11/3 + 11/2. To get the same denominator multiple the top and bottom of the left fraction by 2 and the top and bottom of the right fraction by 3. Then you get 22/6 + 33/6 which is 55/6

-4,-5

Answer:

(x+4)(x+5)

Step-by-step explanation:

Let's factor x2+9x+20

x2+9x+20

The middle number is 9 and the last number is 20.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Addd together to get 9

multiply together to get 20

Can you think of the two numbers? hmmmmmm :D

Try 4 and 5:

4+5 = 9

4*5 = 20

Fill in the blanks in

(x+_)(x+_)

with 4 and 5 to g.et...

(x+4)(x+5)

Hope this helps :D
