Hello! simplified, this question states “3x-3=5x-3”, so your final answer would be “no solutions” since this could not be possible! hoped this helped! ;)

Answer:

x = 0

Step-by-step explanation:

3(x - 1) = 2x - 3 + 3x

3x - 3 = 2x - 3 + 3x

0 - 3 = 2x - 3

0 = 2x

2x = 0

x = 0 ÷ 2

<u>x</u><u> </u><u>=</u><u> </u><u>0</u>

A pharmacist needs 500 milliliters of a 20% phenobarbital solution but has only 5% and 25% phenobarbital solutions available. Fi
sladkih [1.3K]

Let x be ml of 5% soln.

let 500-x be ml of 25% soln.

.

x*.05=.05x

(500-x)*.25=125-.25x

500*.20=100

.

.05x+125-.25x=100

-.2x=-25

x=-25/-.2

x=125 ml of 5% soln.

500-x=375 ml of 25% soln.

.

Check:

125*.05= 6.25

375*.25=93.75

According to a study by de Anna students, the height for Asian adult males is normally distributed with an average of 66 inches
Maslowich
A. X ~ N(66, 6.25)

b.z_{1} =\frac{65-66}{2.5}=-0.4
z_{2} =\frac{69-66}{2.5}=1.2
Using a standard normal probability table to find probability values for the z-scores, we get:
P(65 < X < 69) = 0.1554 + 0.3849 = 0.5403

c. z= 0.524 and -0.524
0.524=\frac{X-66}{2.5}
1.31 = X - 66
X = 67.31
When z = -0.524, X = 64.69.
P(64.69 < X < 67.31) = 0.4

Rae deposit 6,000 into a savings account with an interest rate of 4% compounded monthly. how long will it take for the account t
Dovator [93]

Answer: it will take 13.3 years

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1+r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

P = 6000

A = 10000

r = 4% = 4/100 = 0.04

n = 12 because it was compounded 12 times in a year.

Therefore,.

10000 = 6000(1 + 0.04/12)^12 × t

10000/6000(1 + 0.0033)^12t

1.67 = 1.0033^12t

Taking log to base 10 of both sides, it becomes

Log 1.67 = 12tLog 1.0033

0.223 = 12t × 0.0014

0.223 = 0.0168t

t = 0.223/0.0168

t = 13.3 years
