Solve for x. will give brainlkest

1 answer:

7 0

Simplify both sides of the equation.
(−7.8)(x)+(−7.8)(6.5)=−25.74 −7.8x+−50.7=−25.74 -> −7.8x−50.7=−25.74
Add 50.7 to both sides.
−7.8x−50.7+50.7=−25.74+50.7 -> −7.8x = 24.96
Divide both sides by -7.8.
−7.8x /−7.8 = 24.96/−7.8
And as a decimal
X= −3.2

Hope this helped. (got taken off because I did the steps? oo well)

Which term is not a like term? 3x 4y 7x x

Katena32 [7]

Answer:

4y is not a like term.

Step-by-step explanation:

Unlike the other variables, 4y has a y instead of an x. The numbers with an x variable can all be combined, but 4y can't be combined with an x variable.

Assume Cylinder A and Cone B are the same height and the bases have the same radius. If A has a volume of 18π cm3, what is the v

disa [49]

Answer:

Option A $V_B=19\ cm^3$

Step-by-step explanation:

The volume of a cone is:

$V_B = \pi\frac{hr ^ 2}{3}$

The volume of a cylinder is:

$V_A = \pi(r ^ 2)h$

Both figures have the same height h and the same radius r.

The volume of the cylinder $V_A = 18\pi\ cm ^ 3$

We want to find the volume of the cone.

Then, we find r and h:

$V_A = 18\pi = \pi(r ^ 2)h$

We simplify.

$V_A = 18 = (r ^ 2)h$

Then the product of $(r ^ 2)h = 18$ .

We substitute this in the cone formula and get:

$V_B =\frac{\pi}{3}(18)\\\\V_B = \frac{18}{3}\pi\\\\V_B=19\ cm^3$
