He can mow 12 lawns in 4 hours.
to get the answer you just multiply the amounts of lawns he mowed by the hours it’s asking.
Answer:
x=13
Step-by-step explanation:
1. Isolate the variable
3x - 2 = 37
+2 = +2
2. Divide the equation by the coefficient
3x = 39
/3 /3
3. Answer
x = 13
R could equal any number, but it has to be higher than 4, because 3+4=7.
-45.6 is the answer if you evaluate
Answer:
1.) Yes
2.) Yes
Step-by-step explanation:
Given that
n = k(k + 7)
If k is a positive integer and n = k(k + 7), is n divisible by 6 ?
(1) k is odd. Yes.
Let assume that k = 3
Then, n = 3(3 + 7)
n = 3 × 10
n = 30.
30 is divisible by 6.
(2) When k is divided by 3, the remainder is 2. That is,
Let k = 5
Then,
5/3 = 1 remainder 2
Substitute k into the equation
n = k(k + 7)
n = 5(5 + 7)
n = 5 × 12
n = 60
And 60 is divisible by 6.
Therefore, the answer to both questions is Yes.
