You begin solving the equation 3+4x=513+4x=51 by subtracting 33 from both sides. Which is the best choice for Step 22?

bonufazy [111]

33 +4x = 513
4x = 480 (x = 480/4: x = 120)

Answer
Step 2 Divide each side by 4

Sorry for asking so much;(

Length of line RS is probably 20 because it’s not smaller than the line it’s parallel to but it’s not equal either so the answer has to be c unless there’s a d that’s between 10-20

Describe the correct error -1/4 divided by 3/2=-4/1 multiplied by 3/2= -12/2=-6

Rom4ik [11]

I guess the error is in the calculus.
-1/4 divided by 3/2:
(-1/4)/(3/2): When dividing 2 fractions, its answer is equal to the first fraction multiplied by the inverse of the second.
(-1/4)/(3/2) = -1/4 * 2/3 = -2/12
So -1/4 divided by 3/2 is different from -4/1 multiplied by 3/2.
-1/4 divided by 3/2 = -1/4 multiplied by 2/3.

Hope this Helps! :)

Answer:

P(B and D) = 0.35

Step-by-step explanation:

It is a probability tree diagram. Here to find P(B and D):

apply method:

P(A and B) = P(A) × P(B)

Here given:

P(B) = .5

P(D) = .7

So, P(B and D):

P(B) × P(D)

.5 × .7

.35 ≈ 0.35

Write the first four terms of the sequence defined by An=20-30(n-1)

monitta

The first four terms of sequence is 20, -10, -40, -70

<em><u>Solution:</u></em>

Given that we have to find the first four terms of sequence

<em><u>Given recursive formula is:</u></em>

$a_n = 20 - 30(n-1)$

<em><u>To find the first term, substitute n = 1</u></em>

$a_1 = 20-30(1-1)\\\\a_1 = 20-30(0)\\\\a_1 = 20$

Thus the first term of sequence is 20

<em><u>To find the second term, substitute n = 2</u></em>

$a_2 = 20-30(2-1)\\\\a_2 = 20-30(1)\\\\a_2 = 20-30\\\\a_2 = -10$

Thus the second term of sequence is -10

<em><u>To find the third term, substitute n = 3</u></em>

$a_3 = 20-30(3-1)\\\\a_3 = 20-30(2)\\\\a_3 = 20-60\\\\a_3 = -40$

Thus the third term of sequence is -40

<em><u>To find the fourth term, substitute n = 4</u></em>

$a_4 = 20-30(4-1)\\\\a_4 = 20-30(3)\\\\a_4 = 20-90\\\\a_4 = -70$

Thus the first four terms of sequence is 20, -10, -40, -70
