6. The length of a football field is 30 yards more than its width. Express the length of the field in terms of its width. If the perimeter
of the field is 340 yards. find the width of the field. I

the width be 70 yards

Step-by-step explanation:

The computation of the width of the field is as follows:

As we know that

The Perimeter of the rectangle is

= 2 × (length + width)

Where

Perimeter is 340 yards

Let us assume the width be x

So, the length would be x + 30

Now put these values to the above formula

340 = 2 × (x + x + 30)

340 = 2 × (2x + 30)

340 = 4x + 60

4x = 280

x = 70

The length would be

= 70 + 30

= 100

Hence, the width be 70 yards

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
