Answer: x =3a/b + 8/b

Rewrite the equation as

bx − 8 = a ( 5 −2).

bx − 8 = a(5 −2)

Simplify a(5−2)

Subtract 2 from 5.

bx− 8 = a ⋅ 3

Move 3 to the left of a.

bx − 8 =3a

Add 8 to both sides of the equation.

bx = 3a +8

Divide each term by b and simplify.

x =3a/b + 8/b

Answer:

x = (3a + 8)/b

Step-by-step explanation:

a(5 - 2) = bx – 8

bx = a(5 - 2) + 8

x = (3a + 8)/b

Find the circumference and area of a circle A with a diameter of 26 inches.

makkiz [27]

Answer:

Circumference: 81.681 in; Area: 530.929 in

Step-by-step explanation:

To find circumference we use the formula pi x diameter. Which in this case is pi x 26 in, or approximately 81.681 in.

For the area, we use pi x r^2. r = 1/2 d, so r = 13in. Therefore, the area is equal to 169 x pi in, which is about 530.929 in.

What is the value of this expression? 4/15+3/5−2/3 Enter your answer in the box as a fraction in simplest form.

forsale [732]

Answer:

$\frac{4}{15} + \frac{3}{5} - \frac{2}{3}$

$\frac{4 \times 1}{15 \times 1} + \frac{3 \times 3}{5 \times 3} - \frac{2 \times 5}{3 \times 5}$

$\frac{4}{15} + \frac{9}{15} - \frac{10}{15}$

$\frac{4 + 9 - 10}{15}$

$\frac{13 - 10}{15}$

$\frac{3}{15}$

$\frac{1}{5}$

hope it helps you :)

Doing research for insurance rates, it is found that those aged 30 to 49 drive an average of 38.7 miles per day with a standard

Alja [10]

Answer: 0.4302

Step-by-step explanation:

Given : Mean : $\mu=\text{38.7 miles }$

Standard deviation : $\sigma=\text{6.7 miles }$

Sample size : $n=60$

Also, these distances are normally distributed.

Then , the formula to calculate the z-score is given by :-

$z=\dfrac{x-\mu}{\sigma}$

For x=32.5

$\\\\ z=\dfrac{32.5-38.7}{6.7}=-0.925373134\approx-0.93$

For x=40.5

$\\\\ z=\dfrac{40.5-38.7}{6.7}=0.268656\approx0.27$

The p-value = $P(-0.93$

$=P(0.27)-P(-0.93)=0.6064198- 0.1761855=0.4302343\approx0.4302$

Hence, the required probability :-0.4302
