Answer:

35.75

Step-by-step explanation:

x+7

Now we double it or multiply it by 2.

2(x+7)

And this is supposed to be equal to 85.5

2(x+7) = 85.5

x+7 = 42.75

x = 35.75

Which number makes this sentence true? 7.8×3.6×1=7.8×? 1,3.6,4.6,7.8
marin [14]

In the left hand side, you're multiplying 7.8 by 3.6\times 1

In the right hand side, you're multiplying again 7.8 by a mysterious number.

So, the unknown number must be 3.6\times 1

Every number remains unchanged when multiplied by 1, so the answer is 3.6
