Step-by-step explanation:
THIS EQUATION ONLY WORKS FOR A RIGHT TRIANGLE
How can you solve it if you don't know the equations? :P Just kidding...
n+d=22, so we can say that d=22-n
5n+10d=120, and using d found above in this equation gives you:
5n+10(22-n)=120
5n+220-10n=120
-5n=-100
n=20, and since d=22-n, d=2
So there are two dimes and twenty nickels...
check...
20(5)+2(10)=100+20=120 cents which is $1.20
n+d=22, 20+2=22, 22=22
Answer:
Step-by-step explanation:
When two variables vary inversely, it means that an increase in one would lead to a decrease in the other and vice versa. Since the volume of a gas, V in a container varies inversely with the pressure on the gas, P, if we introduce a constant of proportionality, k, the expression would be
V = k/P
If V = 370 in³ and P = 15psi, then
370 = k/15
k = 370 × 15 = 5550
The equation that relates the volume, V, to the pressure, P would be
V = 5550/P
if the pressure was increased to 25psi, the volume would be
V = 5550/25 = 222 in³
Answer:
The two linear equations are the same line
Step-by-step explanation:
two different linear equations can only possibly intersect at one point. once the two lines intersect, they cannot curve back to intersect once again.
