Answer:
He buys 8 desks and 6 chairs can i have branliest
Step-by-step explanation:
Set up a system of equations
desks = y chairs = x
x+y=14
125x + 515y = 4870
Eliminate,
-125x -125y = -1750
125x + 515 y = 4870
390 y = 3120
y = 8
substitute in 8
x + 8 = 14
x = 6
This is a right triangle, the measure of angle A is 90 degrees.
First thing to do I guess is finding B and C.
tan^-1 (7/12) = 30 degrees
tan^-1 (12/7) = 60 degrees
60 + 30 = 90
180 - 90 = 90. Therefore angle A = 90 degrees
Step-by-step explanation:
Substitute known values of P and Q to solve for k: ... If A varies jointly with b and h and A=6 when b=2 and h=9, find b when A=7 and h=3. ... 140 pounds per square foot, find the volume when the pressure is 185 pounds per square foot
sorry all i got
The answer is simply all you do is subtract 72 from 97 and you'll have the answer which is 25, so the temperature decreased by 25 degrees
