4x+1 = 2x+23

4x = 2x+22

2x = 22

x = 22/2 = 11

x = 11

3x-8 = 3(11)-8 = 33-8 = 25

Answer:

Value of BC is 25 units.

Step-by-step explanation:

Given: AC = 2x+23 units , AB = 4x+1 units and BC = 3x-8 units.

Isosceles triangle states that a triangle with two congruent sides and congruent base angles.[Congruent means equal]

Since, in the given triangle ABC  \angle B = \angle C i.e, base angles are equal.

By definition of isosceles triangle,

⇒ΔABC is an isosceles triangle

AB = AC

4x + 1 = 2x + 23

Subtract 2x from both sides we get;

4x + 1 -2x = 2x + 23 -2x

Simplify:

2x + 1= 23

Subtract 1 from both sides we get;

2x +1 -1 = 23-1

Simplify:

2x = 22

Divide both sides by 2 we get;

x = 11

BC = 3x -8 = 3(11) - 8 = 33 -8 = 25 units

Therefore, the value of side BC is, 25 units.

What are the explicit equation and domain for an arithmetic sequence with a first term of 8 and a second term of 5? 20 pts.
fgiga [73]

ANSWER

a_n = 11 - 3n

EXPLANATION

The explicit rule for an arithmetic sequence is given by:

a_n = a_1 + d(n - 1)

It was given that:

a_1 = 8

and

a_2 = 3

The common difference is

d = 5 - 8 =  - 3

We plug in the values into the explicit formula to get,

a_n = 8+  - 3(n - 1)

Expand to get,

a_n = 8 - 3n  + 3

The explicit rule is

a_n = 11 - 3n

The larger of two numbers is 10 less than twice the smaller number. If the sum of the two
natka813 [3]

Answer:

Let the larger number = y and the smaller number = x.

The largest number is 10 less than twice the smaller number. Remember that less than means subtract the 10 from the other amount while twice means multiply by two. Therefore,

y = 2x - 10

The sum of the two numbers is 38. Remember sum means add the two numbers to get their result. Therefore,

x + y = 38

Since y = 2x - 10, we rewrite the lower equation as:

x + (2x - 10) = 38

Solving:

3x - 10 = 38

3x = 48

x = 16

The lesser number is 16 and the greater number is 2(16) - 10 or 22.
