Answer:  3

Step-by-step explanation:

first substitute 2 into 4, so its 2*4 = 8x


Second, substitute 2 into -3 so itś 2*-3= -6

So, so far we're at 8x-6-8+4+2x, we combine the integers (which is -6 & -8, and we get -14)

So far, we are now at 8x-14=4+2x.

Now we add 14, to cancel out -14.

Then, we add 14 to 4, making 18.

Then, we subtract -2 to cancel out 2x.

Then, we subtract 2x to 8x, Making 6x

Now, final step :)

We divide 6x=18

which is 18 divided by 6

which is 3 :)

You got this, you're doing great!

The surface areas of two similar solids are 340 yd² and 1,158 yd². The volume of the larger solid is 1,712 yd³. What is the volu
ratelena [41]

The ratio of surface area is equal to the ratio of the square of the corresponding dimensions. And ratio of volumes of two solids is equal to the cube of the ratio of the corresponding dimensions .

We start with the relation between ratio of surface area and ratio of corresponding sides. That is

\frac{340}{1158}=(\frac{x}{y} )^2

Here x and y are the corresponding sides .

\frac{x}{y} =\sqrt{\frac{340}{1158} } =0.542

Let the volume of the smaller one be v

\frac{v}{1712}=0.542^3

v=1712*0.542^3=272

So for the smaller solid, volume is 272 . And the correct option is the first option .

What is the slope and y-intercept of y+3= -1/3
bazaltina [42]

Assuming this is written correctly, with no x in the equation, we just solve for y:

y = -3 - 1/3 = -10/3 = 0 x - 10/3

That's slope-intercept form.

Answer: Slope 0, y-intercept -10/3
