Answer:
twice (2)
Step-by-step explanation:
1/4=2/8
2/8+2/8=4/8 or 1/2
5/8-4/8=1/8
Write this story as equations:
s = 5j
(s+12) = 2*(j+12)
Then solve:
5j+12 = 2j + 24 => 3j = 12 => j=4, s=5*4=20
Steve is 20, Janis is 4
In 12 years they will be 32 and 16
Answer:
1 / q^3 = 1 / q^n
n = - 3
Step-by-step explanation:
1/r^-4 = r^4
p^3 * q^2 * p^4 * q^n * r^3 * r^4 = p^7 q ^5 r^7
(p^3 * p^4 *q^2 * r^3 * r^4 ) / ( p^7 * q^5 * r^7) = 1/q^n
(p^7 * q^2 * r^7) / (p^7 * q^5 * r^7) = 1/q^n
q^2 / q^5 = 1/q^n
1 / q^3 = 1 / q^n
Answer:
<h2>(0, 0), (-1, 0), (0, 2)</h2>
Step-by-step explanation:
Look at the picture.
Mark points in the coordinate system.
Find points that lie in the shaded region or on the given lines.
Step-by-step explanation:
- 12x-4y=-8
- y=3x+2
- 12x-4(3x+2)=-8
12x-12x-8=-8
0=0
I think,no solution
