What is the first term, common difference, and 16th term

strojnjashka [21]

Answer:

The 1st term is -67

Step-by-step explanation:

I. When Sn = $\frac{n}{2}$ ( $a_{1} + a_{n}$ )

If Sn = 124, n = 8 and $a_{n}$ = 98

124 = 8/2(a + 98)

124 = 4(a + 98)

124 = 4a + 392

124 - 392 = 4a

-268/4 = a

-67 = $a_{1}$

Hope that help :D

Each of the variables t, w, x, y, and z represents a different positive real number. Given the equations below, which of the 4 v

alex41 [277]

Answer:

y has the greatest value.

Step-by-step explanation:

1.23w = t

Divide both sides by 1.23.

$w=\frac{t}{1.23}$

$w=0.813t$ --- (1)

1.01x = t

Divide both sides by 1.01.

$x=\frac{t}{1.01}$

$x=0.99t$ --- (2)

0.99y = t

Divide both sides by 0.99.

$y=\frac{t}{0.99}$

$y=1.01t$ --- (3)

From (1), (2) and (3), it is clear that y has the greatest value.

Answers and Step-by-step explanations:

9-18.

a) All the angles of a triangle add up to 180, by definition. So, we can write the expression: 30 + 115 + x = 180.

Then, we can just solve for x by subtracting 30 and 115 from both sides:

x = 180 - 115 - 30 = 35 degrees

b) Again all three angles should add up to 180, so:

x + x + x = 180 ⇒ 3x = 180 ⇒ x = 180/3 = 60 degrees

9-19.

a) These angles add up to 180:

2x + x + 30 = 180 ⇒ 3x + 30 = 180 ⇒ 3x = 150 ⇒ x = 50

2x = 50 * 2 = 100

The missing angles are 100 degrees and 50 degrees.

b) Again, these add up to 180:

x + 10 + x + 90 = 180 ⇒ 2x + 100 = 180 ⇒ 2x = 80 ⇒ x = 40

x + 10 = 40 + 10 = 50

The missing angles are 50 degrees and 40 degrees.

Hope this helps!
