Answer:
$40
Step-by-step explanation:
we know that
The linear equation in slope intercept form i equal to

where
y is the amount of her mother's donation
x is the number of miles that Melissa walks
where
m is the slope
b is the y-intercept
In this problem
The slope is

The y-intercept is

substitute

so
For x=15 miles
substitute

The value of x in the congruent triangles abc and dec is 1
<h3>How to determine the value x?</h3>
The question implies that the triangles abc and dec are congruent triangles.
The congruent sides are:
ab = de
bc = ce = 4
ac = cd = 5
The congruent side ab = de implies that:
4x - 1 = x + 2
Collect like terms
4x - x = 2 + 1
Evaluate the like terms
3x = 3
Divide through by 3
x = 1
Hence, the value of x is 1

Two triangles, abc and cde, share a common vertex c on a grid. in triangle abc, side ab is 4x - 1, side bc is 4, side ac is 5. in triangle cde, side cd is 5, side de is x + 2, side ce is 4. If Δabc ≅ Δdec, what is the value of x? a. x = 8 b. x = 5 c. x = 4 d. x = 1 e. x = 2
Answer:
$110
Step-by-step explanation:
Answer:
y = -1/5x + 13.2
Step-by-step explanation:
y = -1/5x + b
12 = -1/5(6) + b
12 = -6/5 + b
13.2 = b
y = -1/5x + 13.2
Drops = 27
First, we need to find the volume of the given tank using the following equation

Now that we know the volume, we need to find out how many drops that we need to use. We can find that out using the following equation
