Answer:
<em>8 adults</em>
Step-by-step explanation:
1.) $78 - $6 = $72
2.) $72/$9 = 8
635/72=-5/2(-11/4+x)
distribute
635/72 = -5/2 * -11/4 - 5/2x
635/72 = 55/8 -5/2 x
multiply each side by 72 to clear the fractions
72*635/72 = 72*(55/8 - 5/2 x)
distribute
635 = 72* 55/8 - 72* 5/2 x
635 = 495 - 180x
subtract 495 from each side
140 = -180 x
divide by -180
-140/180 = x
-14/18 =x
-7/9 =x
K = constant
k * temperature = pressure
or p/t = k
this is gay-lussac's law. are you using temperature in kelvin or is that a mistake while writing the question?
Answer:
Step-by-step explanation:
3x%2B4y=12 Start with the given equation
4y=12-3x Subtract 3+x from both sides
4y=-3x%2B12 Rearrange the equation
y=%28-3x%2B12%29%2F%284%29 Divide both sides by 4
y=%28-3%2F4%29x%2B%2812%29%2F%284%29 Break up the fraction
y=%28-3%2F4%29x%2B3 Reduce
Looking at y=-%283%2F4%29x%2B3 we can see that the equation is in slope-intercept form y=mx%2Bb where the slope is m=-3%2F4 and the y-intercept is b=3
Since b=3 this tells us that the y-intercept is .Remember the y-intercept is the point where the graph intersects with the y-axis
So we have one point
Now since the slope is comprised of the "rise" over the "run" this means
slope=rise%2Frun
Also, because the slope is -3%2F4, this means:
rise%2Frun=-3%2F4
which shows us that the rise is -3 and the run is 4. This means that to go from point to point, we can go down 3 and over 4
So starting at , go down 3 units
and to the right 4 units to get to the next point
Now draw a line through these points to graph y=-%283%2F4%29x%2B3
So this is the graph of y=-%283%2F4%29x%2B3 through the points and
