Answer:
U =
Step-by-step explanation:
Given
T =
Multiply both sides by E
ET = 3U ( divide both sides by 3 )
= U
You just combine like terms
So 4d + - d = 3d
And 3x + 2x = 5x
So the answer is 3d + 5x
The way calculate the volume is l*w*h, 3 times 5 times 7 is 105
Answer: D. 105 km^3
Answer:
y= -2x
Step-by-step explanation:
To find the slope, convert the standard form of the equation into slope intercept form, y=mx+b.
5x-10y=-12
-10y=-5x-12
y=1/2 x + 1.2
The slope is 1/2 and the slope of the new line will be -2 because the negative reciprocal create a perpendicular line. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.
(y-8)=-2(x--4)
y-8=-2(x+4)
y-8=-2x -8
y= -2x +0
The company A equation is y=21x. The company B equation is y=18x+45
The companies will have the same price after 15 shirts are sold. To show work for this, make x in both equations 15 and you should get 315 as the answer for both. 315 is the amount of money spent on shirts.
