I can help you with #20. For example, lets say 3/5, this fraction would be made up of 5 parts and 3 are covered, which doesn't make it full, if it was 5/5 it would be full. When you do something with a reciprocal you turn it over, so 3/5 would be turned over to 5/3, thus making it a whole number

Answer:

Step-by-step explanation:

An isosceles triangle needs to have 2 congruent sides to be considered a isosceles triangle. To find the length of AB use Pythagorean theorem :

a^2+b^2=c^2

substitute the triangle's lengths which are given and you get:

3^2 + 3 ^2= c^2

simplify and you get

c= √18

Repeat for AC and you get the same thing: √18.

AB=AC=√18. The triangle is an isosceles triangle because you have 2 congruent sides.

Can anyone help me with this question? <br>what is 6y+8x=24
Effectus [21]

so you will have to convert it to slope intercept form which is y=mx+B so you will have to isolate the y

6y+8x=24 subtract 8x to both sides

6y=-8x+24

divide 6 by both sides

y= -8/6x + 4

simplify

y= -4/3x + 4

the slope of the line is -4/3
