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:
Step-by-step explanation:
We know
in the third quadrant 
We use a scientific calculator to find the inverse cosine of -0.9041 to find
Since this angle is not in the required quadrant we must find the other angle who has the same cosine. The required angle is equidistant from the found value from the 180 degrees angle, so our solution is
Answer:
Out of mean, median, mode, and range, the answer to this question is mode. If an outlier is removed, mode will not change. Hope this helps!
Answer:
|x| ≥ 7
Step-by-step explanation:
Taking the absolute value means that any value of x will always be positive, meaning that the absolute value of -7 or less would be 7 or greater, which satisfies the inequality above and line graph.
