Tamara rewrote the expression 0.2(4+1.4y-2.1). Her steps are shown.
Step 1: 0.2(4+1.4y-2.1)
Step 2: 4.2+1.6y-1.9
Step 3: 4.2-1.9+1.6y
Step 4: 2.3+1.6y
Which statement identifies and explains the first mistake
Tamara made?

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question

translate k to n and reflect across the line containing jk.

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
