Hey there!

4(x + 5) = 12

4(x) + 4(5) = 12

4x + 20 = 12

SUBTRACT 20 to BOTH SIDES

4x + 20 - 20 = 12 - 20

CANCEL out: 20 - 20 because it gives you 1

KEEP: 12 - 20 because it help solve for the x-value


NEW EQUATION: 4x = 12 - 20


SIMPLIFY IT!

4x = -8

DIVIDE 4 to BOTH SIDES

4x/4 = -8/4

CANCEL out: 4/4 because it gives you 1

KEEP: -8/4 because it gives the x-value


NEW EQUATION: x = -2


Therefore, your answer is s x = -2


Good luck on your assignment & enjoy your day!

Answer:

x = -2

Step-by-step explanation:

you need to use the distribution property first!

4(x + 5) = 12 ------> 4x + 20 = 12

now you need to subtract 20 from both sides so that you can isolate x

4x = -8

finally, divide -8 by four so that x is alone, meaning solve to find x!

x = -2

The volume of the cylinder that has a radius of 7 ft and a height of 5 ft in the geometry will be 769.7 ft³.

<h3>How to illustrate the geometry?</h3>

It should be noted that the volume of a cylinder is given as:

= πr²h

where,

π = 3.142

r = radius = 7

h = height = 5

Therefore, the volume will be:

= πr²h

= 3.142 × 7² × 5

= 3.142 × 49 × 5

= 769.7 ft³

Solve the equation. Then check your solution. – two-fifths + a = One-fifth a. Three-fifths c. StartFraction 3 Over 10 EndFractio
VLD [36.1K]

Answer:

a = Negative one-fifth

Step-by-step explanation:

The given equation is :

\dfrac{2}{5}+a=\dfrac{1}{5}

We need to find the value of a.

Subtract 2/5 from both sides.

\dfrac{2}{5}+a-\dfrac{2}{5}=\dfrac{1}{5}-\dfrac{2}{5}\\\\a=\frac{1}{5}-\frac{2}{5}\\\\a=\dfrac{-1}{5}

So, the correct answer is Negative one-fifth. Hence, the correct option is (b).

Need assistance on some geometry
lukranit [14]

Answer:

So I can't actually put a picture in, put heres the easiest way to understand this. If it says y-1, take the coordinates for y, and subtract 1. do that to all of them, not just 1. For example, R is 4,1. To translate it, you would take the y coordinate (1) and subtract 1. We know to do this because it shows translation x,y)->(x,y-1). Thus, the new point would be 4,0. apply this to all of the points.
