Answer:
Both buses will arrive at the stop at 6:52 AM
Step-by-step explanation:
Wilkenson Bus = Arrives every 21 minutes
Harris Road Bus = Arrives every 15 minutes
Let's find the Least Common Multiple (LCM) of 21 and 15. LCM is found, listing the prime factors of each numbers and then multiplying each factor the greatest number of times it occurs in either numbers:
LCM 21 = 3 × 7
LCM 15 = 3 × 5
LCM (21 , 15) = 3 × 7 × 5 = 105
In 105 minutes both buses will arrive at the same time again
105 minutes = 1 h 45 min
5:07 AM + 1h 45 min = 6:52 AM
X + y = 62
x - y = 12
Move x over so y is alone in one of the above equations,
y = 62-x
Now substitte in y
x-(62-x) = 12
x - 62 + x = 12
2x = 12 + 62
2x/2 = 74/2
x = 37
Now for y sub in the x!
x + y = 62
(37) + y = 62
y = 62 - 37
y = 25.
So 25 + 37 =62
and 37 - 25 = 12
Method 2 :
Start by stacking the 2 original equations from above,
x+y=62
x-y=12
You want to "cancel" out one of the variable so,
x+y=62
+ + = +
x - y =12
So then you add,
2x = 74
2x / 2 = 74 / 2
x = 37.
Now you can once again sub it back into the original equation to solve for y,
x+y=62
(37)+y=62
y=62-37
y=25
Hope this helps!
Answer:
9 × c or 9c
Step-by-step explanation:
Product means multiplication so the answer would be 9 × c. Since there is a variable, the answer doesn't even need the multiplication sign, but it is fine either way.
