w + 4

------------------------

l l

l l w

l l

------------------------

Perimeter would be the sum of all the sides so: (w+4) + w + (w+4) + w

Perimeter is 60 yards according to your problem so: (w+4) + w + (w+4) + w = 60 yds

1.Simplify/combine like terms:

w + 4 + w + w + 4 + w =

4w + 8 =

Now it's a 2-step algebra equation

4w + 8 = 60

2.Subtract 8 on both sides

4w = 56

3.Divide both sides by 4

w = 14

nevsk [136]
In the morning
 (3/4) (strawberries / minutes) * (60/1) (minutes / hours) = 45 (strawberries / hours)
 in the afternoon
 (2/3) (strawberries / minutes) * (60/1) (minutes / hours) = (40 strawberries / hours)
 the difference between your morning and afternoon packing rates, in pints per hour is
 45-40 = 5 (strawberries / hours)

Suppose y = 2x +10. Find y if x = -2.
liubo4ka [24]

If x = -2, y = 6.


To solve this quesiton, we need to find the value of y if x is equal to -2. We can do this by substiuting the value of x and then solving.


y = 2 (-2) + 10


y = -4 + 10


y = 6

If x = 10, find the value of:<br><img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B2%20%7Bx%7D%5E%7B2%7D%28x%20-%205%29%20%7D%7B10x
vesna_86 [32]

Answer:

10

Step-by-step explanation:

\frac{2(10)^2(10-5)}{10(10)}

Square the 10.

\frac{2(100)(10-5)}{10(10)}

Subtract 10 with 5.

\frac{2(100)(5)}{10(10)}

Multiply the numbers in the numerator.

\frac{2(500)}{100}

\frac{1000}{100}

Divide 1000 with 100.

=10
