Answer:
5w -6
Step-by-step explanation:
(W2 – 4w - 1)+(-5 + 5w2 – 3w)
combine like terms in the 2 groups
(-2w-1)+(-5+5w(2) -3w)
(-2w-1)+(-5+10w-3w)
(-2w-1)+(-5+7w)
now add/subtract all
5w -6
1 Expand.
8x-6-8=4+2x8x−6−8=4+2x
2 Simplify 8x-6-88x−6−8 to 8x-148x−14.
8x-14=4+2x8x−14=4+2x
3 Add 1414 to both sides.
8x=4+2x+148x=4+2x+14
4 Simplify 4+2x+144+2x+14 to 2x+182x+18.
8x=2x+188x=2x+18
5 Subtract 2x2x from both sides.
8x-2x=188x−2x=18
6 Simplify 8x-2x8x−2x to 6x6x.
6x=186x=18
7 Divide both sides by 66.
x=\frac{18}{6}x=
6
18
8 Simplify \frac{18}{6}
6
18
to 33.
x=3x=3
Done Hope this helps let me know if u have any questions thank you
Answer: 90 visitors per hour
Explanation: "Per hour" means in 1 hour, so we can rewrite the given statement using fractions as <em>450 visitors/5 hours = __visitors/1 hour</em>.
To find out what goes in the bank, notice that we
have a 1 in the denominator of our second fraction.
So we want to find a fraction that is equivalent
to 450/5 that has a 1 in the denominator.
If we divide the numerator and denominator of 450/5 by 5,
we get the equivalent fraction 90/1 or <em>90 visitors/1 hour</em>.
So now we have <em>90 visitors/1 hour = __visitors/1 hour</em>.
So a 90 must go in the blank.
This means that the museum sees 90 visitors per hour.
Answer: Andy will pay $12.675 in interest for one interest

APR of his credit card = 18%
So, Rate of interest for one month will be

Interest will be paid for one month is given as

Hence, Andy will pay $12.675 in interest for one interest .
Answer:
0.55199
Step-by-step explanation:
When we have a random number of samples, We solve using z score formula
z = (x-μ)/σ/√n where
x is the raw score
μ is the population mean
σ is the population standard deviation
n is random number of samples
z = 0.83/77/√147
z = 0.13069
Probabilty value from Z-Table:
P(x<48.83) = 0.55199
The probability that the mean of the sample would differ from the population mean by less than 0.83 months is 0.55199
