Colleen compared the ratios 3:8 and 1/2.

Her work is shown below.

Write the ratios as fractions: 3/8 and 1/8 Compare the numerators: 3 > 1 Write the correct statement: 3/8 > 1/2

Where did Colleen make her first mistake?

A. The common denominator should be 4 rather than 8

B. The numerators are compared incorrectly.

C. The fraction 1/2 should have been rewritten as 6/8

D. The fraction 1/2 should have been rewritten as 4/8.

Answer:

D. The fraction 1/2 should have been rewritten as 4/8.

Step-by-step explanation:

Colleen compared the ratios 3:8 and 1/2.

Step 1

Write the ratios as fractions: 3/8 and 1/2

Step 2

Compare the numerators: 3 > 1

Step 3

Compare the denominators 8 >2

Write the correct statement:

3/8 > 4/8

Therefore, D. The fraction 1/2 should have been rewritten as 4/8.

Answer: 16

Step-by-step explanation:

Answer:

a = 3

Step-by-step explanation:

Here you can use the cross multiplication strategy or whatever it's called. That's where you multiply the diagonals together. Its kinda long to explain, but you can google it for details.

In either case, you get the following equation:

8(2a-1) = 4(a+7)

Open the parenthesis

16a - 8 = 4a + 28

Subtract 4a from both sides

12a - 8 = 28

Add 8 to both sides

12a = 36

Divide both sides by 12

a = 3

Step-by-step explanation:

Answer:

Subtract 3

Step-by-step explanation:

The first operation that should be done first in the expression 5x + 3 = 28 is subtracting 3 from both sides.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, 5x + 3 = 28.

The first operation that should be done first is subtracting 3 to both the side of the equation to separate the variable x and the constant term.

∴ 5x + 3 - 3 = 28 - 3.

5x = 25.

x = 5.

This uses the cosine Law for line length.

Formula

a^2 = b^2 + c^2 - 2*b*c*sin(A)

Givens

a  = 5

b = 7

c = 10

Solution

5^2 = 7^2 + 10^2 - 2*7*10*cos(A)

25 = 49 + 100 - 140*cos(A)                  Combine the right side

25 = 149 - 140 * cos(A)                         Subtract 149 from both sides

25 - 149 = - 140*cos(A)                    

-124 = -140 * cos(A)                               Divide both sides by -140

-124/-140 = cos(A)

Cos(A) = 0.8857                                   Take the inverse Cos of both sides

A = cos-1(0.8857)

Answer

A = 27.66 degrees

Answer:

41.5

23.5

Step-by-step explanation:

Let's start by calling the two numbers we are looking for x and y.

The sum of x and y is 65. In other words, x plus y equals 65 and can be written as equation A:

x + y = 65

The difference between x and y is -18. In other words, x minus y equals -18 and can be written as equation B:

x - y = -18

Now solve equation B for x to get the revised equation B:

x = -18 + y

Then substitute x in equation A from the revised equation B and then solve for y:

x + y = 65

-18+y+y=65

-18 + 2y = 65

2y = 83

y = 41.5

Now we know y is 41.5. Which means that we can substitute y for 41.5 in equation A and solve for x:

x + y = 65

x + 41.5= 65

X = 23.5

DIfference : 23.5 - 41.5 = 18

Sum: 41.5 +23.5 = 65

Hence, The two number are 23.5 and 41.5

Answer:

- [tex]\frac{1}{4}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

4x - y = 9 ( subtract 4x from both sides )

- y = - 4x + 9 ( multiply through by - 1 )

y = 4x - 9 ← in slope- intercept form

with slope m = 4

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{4}[/tex]

it's C since it also has 4 elements

In the top row, second column, the answer is B) S, T, U. We're naming three points that all fall on the same line.

===============================================

In the bottom row, first column, the answer is A) Point. An example of this is the diagram in the bottom right corner. The lines WV and XZ intersect at the point Y.

Finally, in the bottom row, second column, the answer is D) Ray YW and Ray YV. Like with the first problem, we're listing two rays that when joined, form a straight line. They point in complete opposite directions. The order matters when it comes to naming a ray. The first letter tells us the endpoint and the second letter tells us where the ray points and goes on forever.
