2(x+3)=x-4 please help me <3

1 answer:

2(x + 3) = x - 4

distribute

2x + 6 = x - 4

either subtract 6 from both sides or add 4. i will be subtracting 6.

2x = x - 10

subtract x from both sides

x = -10

oksano4ka [1.4K]

Answer:

a. (2+3)×4²+1=81

b. (2+3)×(4²+1)=85

c. 2+(3×4²)+1=51

d. 2+3×(4²+1)=53

Step-by-step explanation:

a. Parentheses about the 2 + 3 - then use PEMDAS to give 5 * 16.

b Inserting 2 parentheses makes it 5 * 17 = 85.

c.Inserting the parentheses simplifies it to 2 + 48 + 1 = 51.

d. Inserting the parentheses makes it 2 + 3*17 = 53

Important Characteristics Quiz The probability of success in each of the 58 identical engine tests is p = 0.92. What is the mean

Maru [420]

Answer: The mean of this binomial distribution is 53.36.

Step-by-step explanation:

We know that , the mean of this binomial distribution is given by :_

$\mu = np$

, where n = sample size or the number of possible trials .

p = probability of getting success in each trial.

We are given that , the probability of success in each of the 58 identical engine tests is p = 0.92.

i.e. n= 58

p=0.92

Then, the mean of this binomial distribution = $58\times0.92=53.36$

Hence , the mean of this binomial distribution is 53.36.

Step by step workout of ; log x^3+log 5x=5 log 2-log 2/5

Charra [1.4K]

Answer:

x = 2

Step-by-step explanation:

$log \: {x}^{3} + log \: 5x = 5log \: 2 - log \: \frac{2}{5} \\ \\ \therefore \: log( {x}^{3} \times 5x) = log {2}^{5} - log \: \frac{2}{5} \\ \\ \therefore \: log( 5{x}^{4}) = log 32 - log \: \frac{2}{5} \\ \\ \therefore \: log( 5{x}^{4}) = log \bigg(32 \times \frac{5}{2} \bigg) \\ \\ \therefore \: log( 5{x}^{4}) = log \bigg(16 \times 5) \\ \\ \therefore \: 5{x}^{4}= 16 \times 5 \\ \\ \therefore \: {x}^{4}= {2}^{4} \\ \\ \huge \purple{ \boxed{\therefore \: {x} = 2}}$
