x = + or - 5
Answer:
29
Step-by-step explanation:
Let c, r, g stand for the current ages of Carolina, Raul, and Ginny. Then we have the relations ...
c = 2r
g = 3r +4
c + r + g = 52
Substituting for c and g, we get ...
2r + r + (3r +4) = 52
6r = 48 . . . . . . . . . . . . . subtract 4
r = 8 . . . . . . . . . . . . . . . divide by 8
g = 3(8) +4 = 28 . . . . . .Ginny is presently 28
On Ginny's next birthday, she will be 29.
Answer:
sqrt(2)
Step-by-step explanation:
bd=ab/2=2
=> bc=qrt(bd^2+dc^2)=sqrt(4+16)=2sqrt(5)
Answer:
k = -4
Step-by-step explanation:
(k - 10)/2 = -7
First: multiply by 2 to get rid of the denominator
2(k - 10)/2 = 2(-7)
k - 10 = -14
Next: add 10 to both sides to isolate k
k - 10 + 10 = -14 + 10
k = -4
