5/3v = 125/7<br> PLEASE HELP
Oxana [17]

Answer:

v =7/75

Step-by-step explanation:

5/3v = 125/7

\frac{5}{3v} = \frac{125}{7}  cross multiply

5*7 = 125 *3v

35 = 375v divide by 375

v = 35/375

v =7/75

PLEASE HELP!!!!! Consider the functions f(x)=x−7 and g(x)=4x3.<br> What is f(x)+g(x)?
Karolina [17]

Answer:

The answer is 13x-7

Step-by-step explanation:

f(x) is x-7, and g(x) is 4x3. 4x3 can also mean 12x , because 4x3 is 4*x*3. So, f(x) can be replaced with x-7, and g(x) can be replaced by 12x. (x-7)+(12x) is 13x-7.

Which points are solutions to the linear inequality y &lt; 0.5x + 2? Select three options.
Lisa [10]

Some solutions for the given linear inequality:

y < 0.5x + 2

are:

{(0, 1), (1, 2), (2, 2)}

<h3>Which points are solutions of the linear inequality?</h3>

Here we have the linear inequality:

y < 0.5x + 2

To find the points we can evaluate the right side, and then find values of y such that the inequality is true.

For example, if we use x = 0, then we get:

y < 0.5*0 + 2

y < 2

A value of y such that this is true is y = 1

Then the point (0, 1) is a solution of the inequality.

Another example can be with x = 1:

y < 0.5*1 + 2

y < 2.5

This time we can select y = 2, then the solution is (1, 2).

To get a final solution we can evaluate in x = 2

y < 0.5*2 + 2

y < 3

Then a possible solution is y = 2 again, so the solution is (2, 2).

Notice that for each of these values of x, there are a lot of other points that are solutions.

There is an average of 3.5 x 10^−2 kilograms of dissolved salt in each liter of seawater. The South China Sea contains approxima
Fiesta28 [93]
Alright, since there's 3.5*10^(-2) of salt for each liter of seawater, that means that for each liter added we add that to it, meaning that we multiply the amount of salt per liter by the total amount of liters, resulting in 3.5*9.88*10^(-2)*10^18=34.58*10^16 (by adding -2 and 18 we get 16). Since we only want 1 number in front of the decimal (that's not a 0) for scientific notation, we can move the decimal one spot to the left to make it 3.458. However, we can't simply move the decimal without changing the exponent - since we moved it one to the left, we must increase the power from 16 to 17 (conversely, if it moved to the right, we'd decrease the power), resulting in 3.458*10^17
