Answer:

d= 0.2

Step-by-step explanation:

–9.45 + 5.4d + 9.01 = –0.1d + 0.66

STEP 1:

Combine Like Terms:

–9.45 + 5.4d + 9.01 = –0.1d + 0.66

–9.45 + 9.01 = -0.44

-0.44+5.4d=-0.1d+0.66

STEP 2:

Add -0.44 from both sides:

-0.44+5.4d=-0.1d+0.66

-0.44+0.44+5.4d=-0.1d+0.66 +0.44

5.4d=-0.1d+0.66+0.44

STEP 3:

Add:

5.4d=-0.1d+0.66+0.44

0.66+0.44= 1.1

5.4d=-0.1d+1.1

STEP 4:

Add 0.1d from both sides:

5.4d=-0.1d+1.1

5.4d=-0.1d+1.1

5.4d+0.1d=-0.1d+0.1d+1.1

5.4d+0.1d=5.5d

5.5d=1.1

STEP 5:

Divide by the coefficient which is 5.5:

5.5d=1.1

d= 0.2

I hope this helps :)

How was ABCDEFGH transformed to A'B'C'D'E'F'G'H'?

So ur going from a smaller shape to a larger shape....means the scale factor is more then 1. The scale factor is the number that u multiply the original shape by to get the other shape.

so lets look at DE...it is 2.....and D'E' is 6

so 2 * x = 6...with ur scale factor being x
2x = 6
x = 6/2
x = 3.....so the scale factor is 3....because multiplying the original shape by 3, gives u the other shape
