3x+2=x+6
subtract x from both sides,subtract 2 from both sides, gives you 2x=4,then divide by 2 on both sides and x will equal 2. Input the 2 for x and see if it will graph in a straight line on a graph.

Figure AFigure B

Solnce55 [7]

Using the given information, the area of figure B is 315 ft²

<h3>Calculating Area </h3>

From the question, we are to calculate the area of figure B

In the given diagram, figure B is made up of a triangle and a square

∴ Area of figure B = Area of triangle + Area of square

Area of triangle = $\frac{1}{2} bh$

Where b is the base

and h is the height

Area of square = $l^{2}$

Where $l$ is the length of a side

In the diagram,

$l = b = 15 \ ft$

$h =12 \ ft$

∴ Area of figure B = $(\frac{1}{2}\times 15 \times 12) + 15^{2}$

∴ Area of figure B = (15×6) + 225

∴ Area of figure B = 90 + 225

∴ Area of figure B = 315 ft²

Hence, the area of figure B is 315 ft²

Answer:

$\dfrac{a}{b}=0.75$ .

Step-by-step explanation:

If two equations $a_1x+b_1y+c_1=0$ and $a_2x+b_2y+c_2=0$ has infinitely many solutions, then

$\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}=\dfrac{c_1}{c_2}$

The given equations are

$ax+by=10$

$3x+4y=20$

It is given that the above system of equations has infinitely many solutions. So,

$\dfrac{a}{3}=\dfrac{b}{4}=\dfrac{10}{20}$

$\dfrac{a}{3}=\dfrac{b}{4}=\dfrac{1}{2}$

Now,

$\dfrac{a}{3}=\dfrac{1}{2}$ and $\dfrac{b}{4}=\dfrac{1}{2}$

$a=\dfrac{3}{2}$ and $b=\dfrac{4}{2}$

$a=1.5$ and $b=2$

So, a=1.5 and b=2.

Now,

$\dfrac{a}{b}=\dfrac{1.5}{2}=0.75$

Therefore, $\dfrac{a}{b}=0.75$ .
