P = 2j
p + j = 39
2j + j = 39
3j = 39
j = 39/3
j = 13
p = 2j
p = 2(13)
p = 26
so pamela (p) is 26 and jiri (j) is 13
Answer:
0.48
Step-by-step explanation:
the eight is in the hundredths place, which is how you represent a percentage. (correct me if i'm wrong)
6r+7=13+7r
Move 7r to the other side. Sign changes from +7r to -7r.
6r-7r+7=13+7r-7r
6r-7r+7=13
-r+7=13
Move +r to the other side. Sign changes from +7 to -7.
-r+7-7=13-7
-r=6
Multiply by -1 to get positive and for 6
-r(-1)=6(-1)
r=-6
Answer: r=-6
Answer:
c=26
Step-by-step explanation:
So you would use the formula a^2+b^2=c^2
10^2+24^2=c^2
100+576=c^2
C^2=676
c=26
