First, add 2 to both sides: 10(+2)=4x-2(+2) Making the 2 on the right cancel out and the 10 goes up to 12.

Now all you should have is 12=4x, so divide both sides by 4, both 4's cancel out and then you're left with 3 (since 12 divided by 4 is 3).

I'm not really looking for an exact answer, I'm more so looking for an explanation on how to do this.

I would have each block be 1/6 of a yard

You could technically have any value you want, but for me 1/6 is easiest because 1/2 and 1/3 will scale up to this like so

1/2 = (1/2)*(3/3) = 3/6

1/3 = (1/3)*(2/2) = 2/6

The diagram below might help if you're still stuck on why I picked 1/6.

Answer:

D 6

Step-by-step explanation:

Normally when I multiply mixed numbers, I change them to improper fractions first so that it is easier.

1\frac{2}{10} × 5 = \frac{12}{10} × 5

Multiply 5 by the numerator of the fraction and leave the denominator alone.

\frac{12}{10} × 5 = \frac{60}{10}

Change back to simplest form.

\frac{60}{10} = 6

What is the perimeter, P, of a rectangle that has a length of x + 6 and a width of y - 1?
Mekhanik [1.2K]

Answer: P = 2x + 2y + 10

Step-by-step explanation: The perimeter (P) of a rectangle is given as

P = 2L + 2W

By factorizing the right hand side of the equation we now have

P = 2(L + W)

However, the length of the rectangle is given as x + 6 and the width is given as y - 1

If P = 2(L + W), then

P = 2(x + 6 + {y - 1} )

P = 2(x + 6 + y -1)

P = 2(x + y + 5)

After expanding the bracket, we now have

P = 2x + 2y + 10
