<h2>Solving Equations</h2><h3>Answer:</h3>

x = 20

<h3>Step-by-step explanation:</h3>

Given:

\sqrt{\frac{4 +x}{6}} = 2\\

Solution:

\sqrt{\frac{4 +x}{6}} = 2 \\ (\sqrt{\frac{4 +x}{6}})^2 = (2)^2 \\ \frac{4 +x}{6} = 4 \\ \frac{4 +x}{6} \times 6 = 4 \times 6 \\ 4 +x =24 \\ 4 +x -4 \\ 24 -4 \\ x = 20

At a greengrocer, two bananas and one apple cost ?1.16 and one banana and one apple cost ?0.71. How much does one apple cost?
Blababa [14]

Answer

Find out the how much does one apple cost .

To prove

Let us assume that the number of bananas be x .

Let us assume that the number of apples be y .

As given

At a greengrocer, two bananas and one apple cost $1.16 .

Than the equation becomes

2x + y = 1.16

one banana and one apple cost $0.71.

Than the equation becomes

x + y = 0.71

Subtracting x + y = 0.71 from 2x + y = 1.16

2x - x + y - y = 1.16 - 0.71

x = 0.45

Put in the equation x + y = 0.71

0.45 + y = 0.71

y = 0.71 - 0.45

y = $0.26

Therefore the cost of the one apple is  $0.26 .

A line segment with endpoints A = (3, 0) and B = (7,0). Then, plot all points
eduard

Answer:

C(0,6)

Step-by-step explanation:

1) find the length of the base of the triangle

AB = 7-3 = 4

2) find the the height of the triangle

A = (base x height)/2

A x 2 = base x height

height = (A x 2)/base

height = (12 x 2)/4 = 6

3) find the equation of the line that passes threw the points AB

the two points have the same y so the equation of the line is

y = 0

4) use the formula of the distance between a point and a line to find C

|ax+by+c|/√a^2 + b^2 = distance

x = 0  

y = 6

C (0,6)
