Surface area is what it seems to be. All of the area of the solid's faces together. Like a cube, just find the areas of all of the squares that make the cube then add them together.

Solve the system using any method.<br> y = 3x + 2<br> y = 7x - 10

Marysya12 [62]

Answer:

x=3

y=11

Step-by-step explanation:

y = 3x + 2 equation 1

y = 7x - 10 equation 2

using equation 1 in equation 2 we have:

3x + 2 = 7x - 10

2=7x - 3x -10

2 = 4x -10

2+10 = 4x

12= 4x

12/4 = x

we have:

x= 3

using equation 1:

y = 3x + 2

y= 3(3)+2

y=9+2

y=11

Solve for x in the picture please

Nutka1998 [239]

Answer: $x=1$

Step-by-step explanation:

In order to find the value of "x", it is important to remember that:

$Tangent\ chord\ angle=\frac{1}{2}(Intercepted\ arc)$

We can identify in the figure that:

$Tangent\ chord\ angle=(43x)\°\\\\Intercepted\ arc=AB$

Then:

$43x=\frac{1}{2}AB$

Solving for AB:

$2(43x)=AB\\\\AB=86x$

Now, since there are 360° in a circle, we know that:

$AB+(272x+2)=360$

Then we can substitute $AB=86x$ into $AB+(272x+2)=360\°$ and solve for "x". This is:

$(86x)+(272x+2)=360\\\\358x=360-2\\\\x=\frac{358}{358}\\\\x=1$

Answer: Down below

Step-by-step explanation:

We know that 11.9% is the same as .119

The price increase = .119 * 58000 = 6902

The price of the new model is 6902+ 58000
