What is 7/15 • (-3/4) in simplest form?

The answer would be -7/20

Step-by-step explanation:

You have (7/15) * (-3/4)

What you have to do is multiply the numerators, 7 and -3, which is -21.

Then you multiply the denominators, 15 and 4, which is 60.

Your fraction should then look like this (-21/60). *numerator/denominator

Then you simplify them by divided both numbers by 3, which gives your answer, (-7/20).

Since 7 is prime, the fraction can no longer be simplified any more.

-7/20 is the answer

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
