3(x−7)=6(x−10) Solve For X3x-21=6x-60

6 0

Hello,

Let's look at the equation: <span>3(x−7)=6(x−10). Let's distribute the 3 and 6 to the parenthesis. After you distribute, the equation should look like:
3x - 21 = 6x - 60. Then add 21 to both sides and that should leave you with
3x = 6x - 39. Let's then get 6x to the other side by subtracting 6x to both sides. That'll leave you with -3x = -39, then divide each side by -3 to get x by itself. The equation would now be: x = 13. Hope this helps =).

3(x-7)=6(x-10)
3x-21=6x-60
3x-21+21=6x-60+21
3x=6x-39
3x-6x=6x-39-6x
-3x=-39
-3x/-3=-39/-3
x=13

Franklin saved money to buy art supplies

Nikolay [14]

<u>Question</u>:

Franklin saved money to buy art supplies. He used 1/5 of his savings to buy brushes. He used 1/2 of his savings to buy paint. What fraction of his savings does he have remaining?

Answer:

Franklin had $\frac{3}{10}$ of his saving left.

Step-by-step explanation:

Amount used to buy brushes = 1/5

Amount used to buy paint = 1/2

Solution:

Let the remaining amount be x

then ,

x = 1- (amount used on buying brushes + amount used for buying paints)

$x = 1- (\frac{1}{5} + \frac{1}{2})$

$x = 1- (\frac{2+5}{10})$

$x = 1- (\frac{7}{10})$

$x =\frac{10-7}{10}$

$x =\frac{3}{10}$

The commuting time for a student to travel from home to a college campus is normally distributed with a mean of 30 minutes and a

Rainbow [258]

Answer:

0.1587

Step-by-step explanation:

Let X be the commuting time for the student. We know that $X\sim N(30, (5)^2)$ . Then, the normal probability density function for the random variable X is given by

$f(x) = \frac{1}{\sqrt{2\pi(5)^{2}}}\exp[-\frac{(x-\mu)^{2}}{2(5)^{2}}]$ . We are seeking the probability P(X>35) because the student leaves home at 8:25 A.M., we want to know the probability that the student will arrive at the college campus later than 9 A.M. and between 8:25 A.M. and 9 A.M. there are 35 minutes of difference. So,

$P(X>35) = \int\limits_{35}^{\infty}f(x)dx$ = 0.1587

To find this probability you can use either a table from a book or a programming language. We have used the R statistical programming language an the instruction pnorm(35, mean = 30, sd = 5, lower.tail = F)
