Frank is 13 and his sister is 5.
Explanation:
Frank’s age: y=x+8
After 3 years, their ages will be y=x+11 and his sisters age, y=x+3.
In 3 years he will be twice as old.
Equation:
x+11=2•(x+3) -> x=5
Frank is now 5+8=13.
Answer:
B x=2 y=6
Step-by-step explanation:
For ABCD to be parallelogram, following conditions should be satisfied:
2x - 0 = x + 2 & 4y - 8 = y + 10
2x - 0 = x + 2
2x - x = 2
x = 2
4y - 8 = y + 10
4y - y = 10 + 8
3y = 18
y = 18/3
y = 6
Hello,
Here is your answer:
I think the proper answer for this question would be option A "find and interpret the slope." That's just because your trying to find out who much time did it take to drive up I mountain which means you need to calculate the slope!
Your answer is A!
If you need anymore help feel free to ask me!
Hope this helps!
Answer:
x=29+360k
Step-by-step explanation:
sin(x+37)°=cos(2x+8)°
x+37+2πk=2x+8
x=37-8+360k=29+360k
