They both has the same denominator or bottom number like 7/10 - 5/10.

The fractions that have the same denominators are like fractions. They can also be defined as fractions with the same bottom numbers.For example, 11/20, 13/20, 27/20 1/20... These are all like fraction. 

We can also convert unlike fraction to like fraction by simply writting them with denominators been their LCM.

HELP AND PLZ EXPLAIN PLZZZZZZZZZZZZZZZZZZZZZZZZZZZZzz
Yakvenalex [24]
Here, you're mixing scores 85 and 90 with weights X and Y, respectively. You are asked for the ratio of X to Y.

There's a quick way to work mixture problems of all kinds. Write the two components of the mixture on the left. Here, they are 90 and 85. (I usually put the larger one on top.) Put the mixed value in the middle, and form differences along the lines of an X, as shown. The numbers on the right give the relative contributions of the constituents at the same level in the diagram. Here, the ratio of X to Y is shown as 2 to 3.

For some mixture problems, you need to know the proportion of the constituent to the whole. In that case, add the ratio values to get the "whole". For example, here the X class students make up 2/(2+3) = 2/5 of the whole number of students.

For your problem, X/Y = 2/3, corresponding to selection D.

Find all equations that would graph the same line as 5x-3y=8. what else?
ioda
I agree with all your choices. First, you would convert all the equations to slope-intercept form.
Convert the initial equation 5x - 3y = 8 to get y = 5/3x + (-8/3)

We can't do anything with -5 = 3y = -8 because of the equal signs, therefore, option A is eliminated.

Option B in slope-intercept is y = 5x + -8, that is no where close to <span>y = 5/3x + (-8/3), so B is eliminated.
</span>
Option C in slope-intercept form is <span>y = 5/3x + (-8/3), the same as the initial equation, so choice C is correct.
</span>
Option D in slope-intercept form is y = 2.5/-1.5x + 4/-1.5, dividing the fraction results in y = -1.667x + -2.667, -1.667x is the equivalent of -5/3 and -2.667 is the equivalent of (-8/3). It does not matter if the slope is positive or negative, as long as they're the same. Choice D is correct.

Option E in slope-intercept form is y = -25/-15x + 8/-15, dividing -25/15x results in 1.667x, but 8/-15 is -0.534, -0.534 is not equal to -2.667. Choice E is eliminated.

Option F in slope-intercept form is y = -15/-9x + 24/-9, -15/-9 is 1.667 and 24/-9 is -2.667, this is equivalent to  y = 5/3x + (-8/3). <span>Choice F is </span>correct<span>.

I agree with all your answers! :) </span>

I need help with geometry one my question is construct AD congruent to JK​
VARVARA [1.3K]

Answer:

  use your compass to copy the length to a new line

Step-by-step explanation:

To make a line segment that has the same length as another, set your compass width to the length of the one you want to copy, and use that to mark the length on the line where you want your copy.

Use a straightedge to draw a line longer than JK.

  1. Label a point on that line A.
  2. Set your compass to the length JK.
  3. Mark that length from point A on the line you drew. Label the mark D.

AD is congruent to JK.
