<h3>I'll teach you how to solve t + 5 + 3t = 1</h3>

--------------------------------------------------------

t + 5 + 3t = 1

Group like terms:

t+3t+5= 1

Add similar elements:

4t+5=1

Subtract 5 from both sides:

4t+5-5 = 1-5

Simplify:

4t= -4

Divide both sides by 4:

4t/4 = -4/4

Simplify:

t= -1

Your Answer Is t= -1

Hitung jarak di antara titik P(7, 1) dengan titik Q(7, 8)

MaRussiya [10]

Answer:

7 units

Step-by-step explanation:

Distance between 2 points

= $\sqrt{(y1 - y2)^{2} + (x1 - x2) {}^{2} }$

Thus, distance PQ

$=\sqrt{(8 - 1)^{2} + (7 - 7)^{2} } \\ = \sqrt{7^{2} } \\ = 7$

Or you could simply take 8-1= 7 since both points have the same x-coordinate. Thus, PQ is a vertical line and the distance between them is due to the difference in their y-coordinate.

the first term of an arithmetic sequence is -27. the common difference of the sequence is 6. What is the sum of the first 30 ter

Nina [5.8K]

Answer:

1800

Step-by-step explanation:

The sum to n terms of an arithmetic sequence is

$S_{n}$ = $\frac{n}{2}$ [ 2a₁ + (n - 1)d ]

where a₁ is the first term and d the common difference

Here a₁ = - 27 and d = 6, thus

$S_{30}$ = $\frac{30}{2}$ [ (2 × - 27) + (29 × 6) ]

= 15( - 54 + 174)

= 15(120)

= 1800
