Me: in which number is the value of the 9 ten times the value of the 9 in the number 920? a. 509,000 b. 7,190 c. 8,900 d. 293,000 you!

509,000

Step-by-step explanation:

The problem said that the 9 is ten times so when it said that the 920 is an example it actually mean to find that the 9 it gave us we have to find the 9 in the number 920.Here is an equation to help you.

900 x 9=9000.

the number 509,000 has the number 9 in the 1,000 place.

< 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)
