9-x/5=3 solve the folloswing equation for x

Answer:

y = 300

Step-by-step explanation:

The equation of variation in which y varies directly as x is written Mathematically as:

y ∝ x

y = k × x

y = kx

Where k = Proportionality Constant

We find k

a) y = 60 when x = 0.4.

60 = 0.4 × k

k = 60/0.4

k = 150

b) find the value of y when x = 2​

y = kx

k = 150

Hence,

y = 150 × 2

y = 300

The account is not decaying... or going down, it's going up at about 4.5% per year.    so the 5,000 is what is the initial investment,  and the  1.045 is the amount it's going up by,  where the exponent of  't'  is how many times it's going up

Answer:

78%

Step-by-step explanation:

Ok to solve this we can write this as

80 = [tex]\frac{73+82+85+83+x}{5}[/tex]

We put the equation like this because were finding out how much he needs to get on his 5th test x in order to get a 80%

Your grade is the average of all of your scores hence the divided by 5

We next multiply both sides of the equation by 5 to get

400 = 72+82+85+83+x

400=  322+ x

78 = x

He must get a 78% minimum on his next test to get 80%

Hope that helps!

Answer:

46

Step-by-step explanation:

The numbers 45 and 5, in the ratio of 9:1, when added together, sum up to 50.

To split the number 50 into a specific ratio, 9:1. This means we need to divide 50 into two parts, where one part is nine times larger than the other part.

To split 50 into the ratio 9:1, we need to divide the number 50 into two parts, let's call them "x" and "y." The ratio 9:1 tells us that one part is nine times larger than the other. So, we can express this relationship mathematically as:

x = 9y

Now, we know that the sum of the two parts, x and y, should add up to 50:

x + y = 50

Since we have an expression for "x" in terms of "y," we can substitute it into the second equation:

9y + y = 50

Now, let's combine the y terms:

10y = 50

Next, we isolate "y" by dividing both sides of the equation by 10:

y = 50 / 10

y = 5

Now that we've found the value of "y," we can use it to find "x" using the first equation:

x = 9 * 5

x = 45

So, the two parts are x = 45 and y = 5. We can verify that the ratio is indeed 9:1:

x / y = 45 / 5 = 9

And the sum of the two parts is:

45 + 5 = 50

The numbers 45 and 5, in the ratio of 9:1, when added together, sum up to 50.

In summary, to divide 50 into the ratio 9:1, we found that one part (x) is 45, and the other part (y) is 5. This satisfies the condition that one part is nine times larger than the other, and their sum is 50.

Answer:

6 pieces can be cut out of the board

Step-by-step explanation:

The complete question is

James has a board that is 3/4 foot long. He wants to cut the board into pieces that are each 1/8 foot long. How many pieces can James cut from the board?

Solution

Given,

The total length of the board is equal to [tex]\frac{3}{4}[/tex] feet

Total number of pieces to made = X

Size of each piece that is cut from the board is [tex]\frac{1}{8}[/tex] feet long

Total number of pieces that can be cut from the board is equal to total size of board divided by size of each sub part

[tex]X = \frac{\frac{3}{4} }{\frac{1}{8} } \\X = \frac{3}{4} * \frac{8}{1} \\X = 3 * 2 \\X = 6[/tex]

Hence, 6 pieces can be cut out of the board

Answer:

missing length is 8

Step-by-step explanation:

17^2 - 15^2 = 64

square root of 64 is 8

Answer:

8 inches

Step-by-step explanation:

Use the Pythagorean Theorem:

a²+b²=c²

15²+b²=17²

225+b²=289

b²=64

b=8

Therefore, the missing side is 8 inches long.

Given:

The function is:

[tex]C(t)=10(1.029)^{24t}[/tex]

Where, C(t) is the total number of cells after t hours.

To find:

The function that is approximately equivalent to C(t).

Solution:

We have,

[tex]C(t)=10(1.029)^{24t}[/tex]

It can be rewritten as:

[tex]C(t)=10(1.029^{24})^{t}[/tex]            [tex][\because (a^m)^n=a^{mn}][/tex]

[tex]C(t)\approx 10(1.986)^{t}[/tex]         [tex][\because 1.029^{24}\approx 1.986][/tex]

The function [tex]C(t)=10(1.986)^{t}[/tex] is approximately equivalent to C(t).

Therefore, the correct option is 3.
