Answer:

The antebellum period before the Civil War witnessed rapid population and economic growth and several reform movements aimed at improving lives and fulfilling the principles of the American republic. The United States also experienced contention and deep divisions as slavery and the expansion of territory challenged the political balance of power in the nation. The national debate over slavery and its expansion was at the root of the sectional tensions that, despite the efforts of many, led to the Civil War.

If you add 15 to 3 times the mystery number you get 78 was the mystery number
andreyandreev [35.5K]
So the equation looks like this : 15*3x=78
subtract 15 from both sides:        -15      -15
then divide by 3 from both sides
to isolate the variable:                  3x=63
                                                      3/3x=63/3
                                                        x=21 (your mystery number is 21)

Billy has x marbles. Write an
babymother [125]

Answer:

Charlie = 5 + x

Danny = x - 8

Eric = 3x

Step-by-step explanation:

Given

Billy's Marble = x

Required

Determine a,b and c

a. Charlie's Marble

"5 more" means 5 + or + 5

Since Billy's Marble is represented with x, then Charlie's Marbles will be

Charlie = 5 + x

b. Danny's Marbles

Having "8 fewer" means we have to subtract 8 from Billy's marble;

Since Billy's Marble is represented with x, then Danny's Marbles will be

Danny = x - 8

c. Eric Marbles

Having "three times as " means we have to multiply Bill's marble by 3;

Since Billy's Marble is represented with x, then Danny's Marbles will be

Eric = 3 * x

Eric = 3x

Given: ABCD is a ∥-gram; DE ∩ AB =F <br> Prove: △ADF∼△CDE
Vedmedyk [2.9K]

Answer:

By AA similarity

Step-by-step explanation:

We have been given that ABCD is a parallelogram

So, by the property of parallelogram AB ||CD and FD is cutting the line BC

Hence, FD is transverse line. In transverse line alternate angles are equal.

Therefore, ∠AFD=∠EDC  (alternate interior angles)

And ∠FAD=∠ECD (opposite angles in parallelogram)

Therefore, by AA similarity △ADF∼△CDE
