Enter your answer in the box.
TEA [102]
This is an arithmetic series,
so 
S(n) = (n/2)*(a(1)+a(n))
S(25) = (25/2)*(a(1)+a(25))
n=25
a(n) = 3n-2
a(1)= 3*1-2=1
a(1)=1
a(25) = 3*25-2=75-2=73
a(25)=73

S(25) = (25/2)*(1+73)=(25/2)*74=925
S(25)=925

Answer : 925

Sally has only nickels and dimes in her money box. She knows that she has less than $20 in the box. Let x represent the number o
ohaa [14]

Answer:

Draw a dashed line to represent the graph of 5x + 10y = 2000 and shade the portion below the line for positive values of x and y

Step-by-step explanation:

Let

x------> the number of nickels in the box

y------> the number of dimes in the box

we know that

0.05x+0.10y < 20\$

Multiply by 100 both sides

5x+10y < 2000 ------> inequality that represent the situation

The solution of the inequality is the triangular shaded area below the dashed line

see the attached figure

therefore

The statement which best describes the steps to graph the solution to the inequality in x and y is

Draw a dashed line to represent the graph of 5x + 10y = 2000 and shade the portion below the line for positive values of x and y

Equations<br> Solve T = C(9+ AB) for B
MaRussiya [10]

Answer:

Simplifying

T = C(9 + AB) * forB

Reorder the terms for easier multiplication:

T = C * forB(9 + AB)

Multiply C * forB

T = forBC(9 + AB)

T = (9 * forBC + AB * forBC)

Reorder the terms:

T = (forAB2C + 9forBC)

T = (forAB2C + 9forBC)

Solving

T = forAB2C + 9forBC

Solving for variable 'T'.

Move all terms containing T to the left, all other terms to the right.

Simplifying

T = forAB2C + 9forBC

Step-by-step explanation:

Simplifying

T = C(9 + AB) * forB

Reorder the terms for easier multiplication:

T = C * forB(9 + AB)

Multiply C * forB

T = forBC(9 + AB)

T = (9 * forBC + AB * forBC)

Reorder the terms:

when you subtract one negative integer from another, will your answer be greater or less than the integer you started with
vivado [14]
Lets find out...

-5 - (-2) = -5 + 2 = -3....-3 is greater then -5
-1 - (-3) = -1 + 3 = 2.....2 is greater then -1
-4 - (-2) = -4 + 2 = -2...-2 is greater then -4

so it looks like it is going to be greater then the number u started with.
