Remember

we can do anything to an equation as long as we do it to both sides

try to isolate the variable

you have 2 types
x+b=c
x/b=c

fior the first type, minus b from both sides to get
x=c-b

for the second, multiply both sides by b to get rid of the fraction to get
x=cb

also remember that -x times -1=x



b.add 25 to both sides
-a=20
multiply -1
a=-20


c.
-t/8=-4
multiply both sides by 8
-t=-32
mutiply -1
t=32

d. -n/-5=-30
mulitply both sides by -5
-n=150
multiply both sides by -1
n=-150

e. multiply both sides by 12
-l=144
multiply b y-1
l=-144

H (-8, -2)
Mnenie [13.5K]

Answer:

y = 23x + 182

Step-by-step explanation:

m = 23 (parallel line has same gradient)

y = 23x + c

H(-8,-2)

-2 = 23(-8) + c

c = 182

y = 23x + 182

Which of the following are solutions to |x-1|=5x+2
ruslelena [56]

Answer:

-3/4

Step-by-step explanation:

x - 1 = 5x + 2

or, 5x + 2 = x - 1

or, 5x - x = - 1 - 2

or, 4x = - 3

or, x = - 3 / 4

Assume that the random variable X is normally​ distributed, with mean muequals45 and standard deviation sigmaequals10. Compute t
saul85 [17]

Answer:

0.1069 = 10.69%

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question:

\mu = 45, \sigma = 10

Between 57 and 69

This is the pvalue of Z when X = 69 subtracted by the pvalue of Z when X = 57. So

X = 69

Z = \frac{X - \mu}{\sigma}

Z = \frac{69 - 45}{10}

Z = 2.4

Z = 2.4 has a pvalue of 0.9918

X = 57

Z = \frac{X - \mu}{\sigma}

Z = \frac{57 - 45}{10}

Z = 1.2

Z = 1.2 has a pvalue of 0.8849

0.9918 - 0.8849 = 0.1069 = 10.69%

Dmitry [639]

Answer: he fly 107.76 miles per hour for each hour

Step-by-step explanation:

Charles Lendbergh had his first solo flight across the Atlantic Ocean. He flew 3,610 miles in 33.5 hours.

Speed = distance /time

If he flew about the same number of miles each hour, it means that the number of miles that he flies in each hour would be

3610/33.5

= 107.76.miles per hour.
