How can this model be used to determine 2.4−0.15 ? Enter your answers in the boxes.

The model shows a total of 2 wholes and 4 tenths. After regrouping 1 tenth into 10 hundredths, there are 2 wholes,
tenths, and
hundredths. After crossing out 1 tenth and 5 hundredths, there are 2 wholes,
tenths, and
hundredths remaining. Therefore, the difference of 2.4 and 0.15 is
.
Two large squares, each divided into a 10 by 10 grid of 100 small squares. Four columns, each divided into 10 small squares.

step-by-step explanation:

try remembering the steps

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
