The answer is going to be D.
Answer:
x = 60
Step-by-step explanation:
<u>Step 1: Subtract 5 from both sides
</u>
65 - 5 = 5 + x - 5
60 = x
Answer: x = 60
they're equidistant, so distance should be equal.
distance of City centre is
distance of mall is simply $x$. (ordinate is 0, means the point is on x axis , and that's the distance from origin)
thus, $$x=7$$
The answer should be B) an=3+5(n-1)
hope i helped :)
Okay so lets call Leah "L" and her cousin "C". We know that L+C=36 ... we also know that Leah is twice her cousins age. Therefore, L=2 times C, or L=2C. This is because Leah's age is equivalent to twice as much as her cousin's.
Now that you know that L=2C, you can plug this back into the equation. This should make it so that's there's only one variable now!
L+C=36
(2C)+C=36 ... here we subbed in L=2C
3C=36 ... we add up the C's
C=12 ... we isolate for C by dividing both sides by 3
So her cousin's age is 12 years old. Leah's age is twice that. Thus, she's 24. If you add the two up: 12+24, you indeed get 36. Hope that helps :))
