Answer:
They surveyed 300 students
Step-by-step explanation:
In order to find this, take the number who said they speak Spanish and then divide that number by the percentage.
36 students / 12% = 300 total students.
7(a - 10) = 13 - 2(2a + 3)
7a - 70 = 13 - 4a - 6 = 7 - 4a
7a + 4a = 7 + 70
11a = 77
a = 77/11 = 7
a = 7.
1. divide 8.75 by 3.5 and divide 9.75 by 3.75
2. do 2.5 ×2 plus 1.25
F(x) = 20x+300
you sub in the x values (120 hours and 100 hours) for each equation
the only one they both work for is the last one
f(x) = 20x + 300
f(100) = (20 * 100) + 300 = 2000 + 300 = 2300
f(120) = (20 * 120) + 300 = 2400 + 300 = 2700
6 seconds = 540 m
-----------------------------
Find 1 second:
-----------------------------
6 sec = 540 m
1 sec = 540 ÷ 6
1 sec = 90m
-----------------------------
Find 4 seconds:
-----------------------------
1 sec = 90m
4 sec = 90 x 4
4 sec = 360 m
----------------------------------------------------------
Answer: It can travel 360m in 4 seconds.
