The number of people which gets 1/6 of the pizza as required for lunch the next day is; 4 persons.
<h3>What is the number of people who get 1/6 of the pizza for lunch?</h3>
It follows from the task content that only 4/6 of the pizza is left and each individual needs 1/6 of the pizza for lunch.
On this note, the 4/6 fraction of pizza left mean: 4 × 1/6.
Therefore, only four persons get lunch.

Answer:
Step-by-step explanation:
To find the slope, rearrange the equation to y=mx+b or y=mx+c.
Subtract 4x from both sides:
Divide 5 on both sides:
In the equation of y=mx+b/y=mx+c, m will be the slope.
Therefore, the slope is
Ok, so the starting numbers are the fixed amounts. If we think of a graph, this is the y-intercept/ starting point and the rate would continue from there. This conclusion is very important to writing a linear equation in slope-intercept form.
If you don’t remember, slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.
First, let’s make our equations.....
Plan A: y = 0.07x + 26
Plan B: y = 0.12x + 17
Now since it is not stated, I’m not sure if you need to find where the cost of both plans is equal, but that would be found by setting up a system of equations and using substitution.
y = 0.07x + 26
y = 0.12x + 17
Substitute one equation into the other...
0.07x + 26 = 0.12x + 17
- 0.05x = -9
0.05x = 9
x = 180
And there you have it! After 180 minutes [3 hours] of talking, both phone plans will have the same cost.
The total R value is computed from the R-values of the components in the stack as ...
(inches of wood)*(R-value of wood) +(inches of fiberglass)*(R-value of fiberglass) +(inches of foam)*(R-value of foam)
= (4 in)(2 /in) +(2 in)(4 /in) +(3 in)(5 /in)
= 8 +8 +15
= 31
The total R-value of the wall is 31.
