Answer:
x ≥ −4
The line is shaded to the right of −4 where the values are greater. The closed circle indicates that −4 is include
Answer:
.1 (or 1/10)
Step-by-step explanation:
3 * 10^9 = 3 * 10^8/x
<em>Use PEMDAS to interpret</em>
3* 10^9 = 3 * (10^8)/x
<em>Divide both sides by 3</em>
10^9 = (10^8)/x
<em>Divide both sides by 10^8</em>
10 = 1/x
<em>Find the reciprocal of both sides</em>
1/10 = x
To solve this problem, you have to use a proportion:
7/20 = x/100
After setting up the proportion, you have to cross multiply:
20x=700
Now, solve the equation by dividing by 20 on both sides:
x=35
So Charles has 35 laps left.
-4x+4x +5y +6y = 17-6
11y=11
divide both side by 11 to isolate y
y=1
4x+6(1) = -6
subtract 6 on both sides
4x=-12
divide 4 on both sides
x=-3
6 wore blue + 5 wore green + 3 wore black = 14
If there are a total of 18 total students, then the number of people who wore other colored shirts is 4 because 18-14= 4. Therefore, 4/14, which is 2/7 simplified, represents the students who did not wear blue, green or black.
