4(-5y) + 2y = 180
-20y + 2y = 180
-18y = 180
y = -10
x = 50
There are many ways to do this depending on the property you have to use:
If you use the distributive property, you need to distribute 3/4 to -10 and 2/5. Distribute means you will multiply it so your resulting equation will be this:

Before you can add, you need to first make them like terms because you cannot add unlike fractions. Get the LCD and form your new equation:

Now you can just add them together to get:

and then simplify your fraction:

or -
The whole fraction becomes negative because when you divide integers and of them is negative, the final answer will be negative.

Answer:
6 samples
Step-by-step explanation:
Given :
Sample size, = n
Standard deviation, = 6000
Margin of Error = 2000
Confidence interval, α = 95%
Zcritical at 95% = 1.96
n = (Zcritical * σ) / margin of error
n = (1.96 * 6000) /2000
n = 11760 / 2000
n = 5.88
n = 6 samples
Answer:
16m
Step-by-step explanation:
Since the length of the park is 7m, then the other side is also 7m so 46-14 is 32. So 32/2 is 16.
