Answer:
-79, -55, 18, 44, 101, 143
Step-by-step explanation:
Now,
G - Ginny's age.
P=G+8, Percy's age.
In 10 years,
G + 10 - Ginny's age in 10 years.
P+10 - Percy's age in 10 years.
<span> In ten years time Percy (P+10) will be three times Ginnys present age (3G).
P+10=3G
Now we have 2 equations, and we can write a system of equations.
</span>(1) P=G+8
(2) P+10=3G -------> G=(P+10)/3, we need to substitute it into equation 1.
( P=(P+10)/3+8) /*3
3P=P +10+24
2P = 34
P = 17
Percy is 17 years old now.
Check,
P=17, G=17-8=9
P+10=3G , 17+10=3*9, 27 = 27 True
Answer:
The second one
Step-by-step explanation:
Answer:
slope = -3/2
y intercept = (0,0)
equation, y = -3/2x+0
Step-by-step explanation:
y2-y1/x2-x1 = -3-3/2--2 = -6/4 = slope = -3/2
y intercept = (0,0)
Answer:
Whoa this is HARD but this "box" is 6000.
Step-by-step explanation: oh well :/
