How to do substitution

1 answer:

4 0

Substitution is where you place a number instead of a letter. If you they give you a question let’s say “what is he value of x when x=5”
And he equation is
8x=40 (super easy equation but oh well)
So you “substitute” the x
So it will be
8*5=40
Hope this helped and I’m not sure if I made any sense at all but I tried

Write the equation of the arithmetic and geometricsequences given 15, 5, ...

ivann1987 [24]

Step-by-step explanation:

Arithmetic:

a(n) = a +(n-1)d

a=15

d=5-15=-10

°.° a(n) = 15 +(n–1)-10

Geometric:

a(n)=a*r^(n-1)

a=15

r=5/15=1/3

a(n)=15*(1/3)^(n-1)

hope this helps

5x + 4 = -6

5x= -6-4

5x=-10

x=-2

The value of the first expression is x=-2.

x/2 + 3 = 2

x/2 = 2-3

x/2 = -1

x=-2

The value of the second expression is x=-2.

2x+14=10

2x=-4

x=-2

The value of the third expression is x=-2.

-2=-x

2=x

The value of the fourth expression is x=2.

The prism is completely filled with 1750 cubes that have edge length of 15 ft.

neonofarm [45]

The volume of the prism = 14 ft³

Solution:

Number of cubes in the prism = 1750

Edge length of each cube (a) = $\frac{1}{5}$ ft

<u>To find the volume of each cube:</u>

Volume of each cube = a³

$$=\left(\frac{1}{5} \right)^3$

Volume of each cube $$=\frac{1}{125} \ \text{ft}^3$

<u>To find the volume of the prism:</u>

Volume of the prism = Volume of each cube × Number of cubes

$$=\frac{1}{125} \ \text{ft}^3\times 1750$

= 14 ft³

The volume of the prism = 14 ft³
