Step 3 we're adding 28 to both sides which leads to step 4, where we are combining like terms. On the left side -28+28 turns into 0 and effectively goes away. On the right side 64+28 becomes 92

Answer: C) step 4

36x+32=32x-36 whats the value of x

bulgar [2K]

Answer:

$x = -17$

Step-by-step explanation:

Step 1: Subtract 32x from both sides

$36x + 32 - 32x = 32x - 36 - 32x$

$4x + 32 = -36$

Step 2: Subtract 32 from both sides

$4x + 32 - 32 = -36 - 32$

$4x = -68$

Step 3: Divide both sides by 4

$4x / 4 = -68 / 4$

$x = -17$

Answer: $x = -17$

It is 7 kilometers from kerrys house to the mall. About what is that distance in miles?

GenaCL600 [577]

Answer:

$\huge\boxed{\approx 4.4 \ \text{miles}}$

Step-by-step explanation:

In order to convert kilometers to miles, we can use a formula, assuming $m$ is miles and $k$ is kilometers.

$m = \frac{k}{1.609}$ .

Since we know the kilometer reading (7), we can divide this by 1.609 to get our total miles.

$7 \div 1.609 \approx 4.4$

Hope this helped!
