Answer:

StartFraction x over 7.5 EndFraction = StartFraction 12 over 1 EndFraction

Step-by-step explanation:

Here, in this question, given that Rosa earns $12 in an hour, she earns x dollars in 7.5 hours. So we are interested in finding the value of x.

Let’s write this in terms of proportion;

$12 = 1 hour

$x = 7.5 hours

$12 * 7.5 hours = $x * 1 hour

So this can be rewritten as;

$x/7.5 = $12/1 hour

What is the lengthof a hypotenuse of the right triangle ABC in the figure
Harrizon [31]
There is no figure. 
but you can use A^2 + B^2 = C^2
C is your hypotenuse. 
so if you have the other two lengths if you square them and add them you'll have C squared. So you'll have to find the square root of that number to actually find the length.

3(5x - 2) = 11x<br>I am to find x​
Marat540 [252]

Answer:

step 1: claw (aka distributive property)

multiply 3 by the inside bracket. For example, 3 times 5x= 15x and 3 times negative 2 is negative 6.

15x -6 = 11x

put the x together:

15x - 11x = 6

4x =6

x= 6/4

Finally reduce your answer:

x= 3/2

hope this helps
