The values x and y are determined when we use the substitution method.
y = x + 5
Apply eh value of y into the equation to solve for x.
3x + y = 25
3x + x + 5 = 25
Combine like terms
3x + x = 4x
4x + 5 = 25
-5 -5 4x = 20
4x/4 = 20/4
x = 20/4
x= 5
Now we know the value of x, and we need to solve for y.
y = x + 5
y = 5 + 5
y = 10
10 = 10
Now we know both of these values.
Answer:
x = 5
<span>y = 10</span>
Answer:
A
Step-by-step explanation:
A point estimate is the value of a sample characteristic (obtained from the sample)
Sample mean is a point estimate of the population parameter
A) $1195 + 128(6 chairs)
= $1195 + 768
= $1963
B) 3756 - 1963 = 1793
Answer:
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
<em>In the right triangle ABC</em>
-----> by a 45°-90°-45° triangle
so
substitute the values
<em>In the right triangle BCD</em>
substitute the values
It's 9,000 rounded everything
