Based on the solution below, we have:
A. a + 2b =5 corresponds to 5. a = 5 - 2b;
B. 5a = 2b corresponds to 1. a = 2b/5;
C. a + 5 = 2b corresponds to 4. a = 2b - 5;
D. 5(a + 2b) = 0 corresponds to 3. a = -2b; and
E. 5a + 2b=0 corresponds to 2. a = -2b/5.
How do we solve an equation for a variable?For clarity purposes, the equations in the question are restated as follows:
A. a + 2b = 5 1. a = 2b/5
B. 5a = 2b 2. a = -2b/5
C. a + 5 = 2b 3. a = -2b
D. 5(a + 2b) = 0 4. a = 2b-5
E. 5a + 2b =0 5. a = 5-2b
A. From the equation a + 2b = 5, a can be solved as follows:
a + 2b = 5
a = 5 - 2b
B. From the equation 5a = 2b, a can be solved as follows:
5a = 2b
a = 2b/5
C. From the equation a + 5 = 2b, a can be solved as follows:
a + 5 = 2b
a = 2b - 5
D. From the equation 5(a + 2b) = 0, a can be solved as follows:
5(a + 2b) = 0
5a + 10b = 0
5a = -10b
a = -10b/5
a = -2b
E. From the equation 5a + 2b =0, a can be solved as follows:
5a + 2b =0
5a = -2b
a = -2b/5

Answer:
To sum up, the gcf of 76 and 20 is 4. In common notation: gcf (76,20) = 4
Answer:
GCF = 4
Step-by-step explanation:
Expand each and find numbers that each has in common:
20 = 2 x 2 x 5
36 = 2 x 2 x 3 x 3

−3 Which is the correct graph for the compound inequality
The correct graph for the compound inequality is the third graph.
Graph of Inequality
From the question, we are to determine the correct graph to the given compound inequality
The given compound inequality is
-3 < x ≤ 4
This means
-3 < x and x ≤ 4
That is,
x > -3 and x ≤ 4
The graph of x > -3 will start at -3 on the number line without shading the circle and it will point in the right direction
The graph of x ≤ 4 will start at 4 on the number line, with the circle shaded, and it will point towards the left
Joining the two graphs, we will get a number line starting at -3, unshaded, and ending at 4 shaded.
Hence, the correct graph for the compound inequality is the third graph.

Answer:
Equation: m = 35 + 0.17p
Solution: $86
Explanation:
After writing the equation, plug in the value 300 to the variable p. You get m = 35 + 0.17(300). From there you multiply to get m = 35 + 51. Then add to get an answer of $86.

Point P is located 3/5 of the way from point A to point E. Point A is located at (-1, -1) and point P is located
at (-7,5). What are the coordinates for point E?
By using the line segment formula, we conclude that the coordinates of point E are E(x, y) = (- 11, 9).
How to determine the coordinates of the missing endpoint of a line segment
In this problem we find a line segment of which the coordinates of an endpoint and a point within the segment and in accordance with a segment ratio are known. The coordinates of the other endpoint must be found in accordance with the following expression:
E(x, y) = A(x, y) + k · [P(x, y) - A(x, y)] (1)
Where E(x, y) is the missing endpoint.
If we know that A(x, y) = (- 1, - 1), P(x, y) = (- 7, 5) and k = 5 / 3, then the coordinates of point E are:
E(x, y) = (- 1, - 1) + (5 / 3) · [(- 7, 5) - (- 1, - 1)]
E(x, y) = (- 1, - 1) + (5 / 3) · (- 6, 6)
E(x, y) = (- 1, - 1) + (- 10, 10)
E(x, y) = (- 11, 9)

The computation shows that the degree of freedom for the numerator is 2 while it's 67 for the denominator.
How to compute the value?It should be noted that degree of freedom is calculated as:
= k - 1
where k = variable in a data
k = 3.
Degree of freedom = 3 - 1 = 2
The degree of freedom for numerator is 2.
The degree of freedom for denominator is:
n - k
= 70 - 3
