Need help ASAP:)))))))))))))<br>Pls show ur work!<br>1.2x + 7 - 5x <br><br>2.2c - 3 = 2(6 - c) + 7c
USPshnik [31]

Answer:

c = -75/14 OR c = -5.357143

Step-by-step explanation:

Simplify both equations:

1.2x + 7 - 5x =

-3.8x + 7

2.2c - 3 = 2(6 - c) + 7c =

c = −5.357143

OR

c = -75/14

The question wasn't quite clear, if this wasn't correct, please elaborate on what needed to be solved, and I'll fix my answer.

Hope this helped!

Assume you are planning a picnic for lunch, but when you woke up there were rain clouds in the sky. If 50% of rainy days start w
Tasya [4]

Answer:

0.25 = 25% probability that it will rain today and ruin your picnic

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

P(B|A) = \frac{P(A \cap B)}{P(A)}

In which

P(B|A) is the probability of event B happening, given that A happened.

P(A \cap B) is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Cloudy skies

Event B: Rain

20% of all days start with clouds in the air

This means that P(A) = 0.2

50% of rainy days start with rain clouds in the air

50% of 10%. So

P(A \cap B) = 0.5*0.1 = 0.05

What is the probability that it will rain today and ruin your picnic

P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.05}{0.2} = 0.25

0.25 = 25% probability that it will rain today and ruin your picnic

Solve the equation below for x. −12(3x−4)=11 A. −1323 B. −813 C. −6 D. 6
geniusboy [140]

-1/2( 3x -4) = 11

Use distributive properties:

-3/2 + 2,= 11

Subtract 2 from both sides:

-3/2x = 9

Divide both sides by -3/2

X = 9/ -3/2

X = -6

The answer is c. -6

5 is what percentage of 25? I’ll give brainliest:)
lord [1]

Hi there! :)

<h2>20%</h2><h2></h2>

To solve, we can simply divide and multiply by 100 to solve for the percentage:

5 / 25     = 5 ÷ 25 = 1/5 or 0.20

Multiply the decimal by 100 to solve for the percentage:

0.20 × 100 = 20%
