Ok! So because we have to use the order of operations you have to start inside the parentheses 5^2=25 then 25-10=15 next you have to do you second set of exponents outside the parentheses 2^3= 8 now you have the equation now u just solve left to right

You have to first do parentheses so we start in there: 5^2= 25 so 25-10= 15, we next move on to exponents (which is also why we did that first in the parentheses btw) so 2^3= 8, now we’re gonna go in order since it’s all multiplication and division: 15/5=3, then 3x8=24!

BRAINLIESTTT ASAP!! PLEASE HELP ME :)

Answer: approximately 5.1818 pounds per square inch (psi)

========================================================

Work Shown:

P = pressure

T = temperature

The pressure is directly proportional to the temperature, which means P = k*T where k is some constant. As T goes up, P goes up as well, and vice versa. If P goes down, then T goes down too (or vice versa). In short, P and T go up together or go down together.

We're told that 6 psi (pounds per square inch) correspond to a temperature of 440 degrees F. This means P = 6 and T = 440 pair up. Let's use this P and T pairing to find k.

P = k*T

6 = k*440

6/440 = k

k = 6/440

k = 3/220

Therefore, the equation

P = k*T

updates to

P = (3/220)*T

--------------------

The last step is to plug in T = 380 to figure out the paired value of P

P = (3/220)*T

P = (3/220)*380

P = 5.1818 approximately

If y = 3 when X = -9 find X when y =5
kogti [31]
We don't have enough information to answer that question.

You haven't told us anything about how 'y' depends on 'x',
or how 'y' reacts to a change in 'x'.

If we think about it in terms of a graph, you've given us one point
on the graph . . . the point  (-9, 3).  In order to answer the question,
we need to know something about the line that goes through the
point.  But you haven't told us anything about that, and there are
an infinite number of different lines that can go through one point.
