Answer:
1440
Step-by-step explanation:
Let's say x = number of hours worked per week for 12 people. Now one worker works 30 hours a week so if you multiply 12 workers by 30 you will get how many hours 12 workers worked. so x = 12 • 30. 12 • 30 is 360. so x = 360 or for 1 week 12 workers worked 360 hours. now we need to find the amount of hours for 4 weeks. so we can do 4x or 4 times the amount of hours per one week. since x = 360. 4 • 360 = 1440.
Answer:
9*40+9*6 or 9*46
Step-by-step explanation:
We can use the distributive property to factor out 46.
Answer:
NATHAN RODE 2 MILES
Step-by-step explanation:
Let N = Nathan's number of miles
Let M = 5N - 4 (Miguel rode his bicycle 4 miles less than 5 times the number of miles Nathan rode.
M = 6 (Miguel rode his bicycle 6 miles.)
6 = 5N - 4 (Substitute 6 for M in the equation above(M = 5N - 4).
6 + 4 = 5N - 4 + 4 (Add 4 to both sides of equation.)
10 = 5N
10/5 = 5N/5 (Divide both sides by 5 to isolate the variable N.)
2 = N
ANSWER: NATHAN RODE 2 MILES
CHECKING:
DOES MIGUEL'S 6 MILES EQUAL 5N - 4?
5N - 4 = (5)(2) - 4 = 10 - 4 = 6 MILES .
YES IT DOES.
