The answer is c because you have to say 27 minus the number minus 3
Answer: x ≈ 6.86°
Step-by-step explanation:
Firstly, set them equal to each other:
(7x + 24) = 72°
Subtract 24 from both sides:
7x = 48°
Divide both sides by 7:
x ≈ 6.857...
This can be rounded to:
x ≈ 6.86°
Answer:
y < 45
Step-by-step explanation:
Pittsburgh Steelers scored 45 points.
The Miami Dolphins will be represented by a variable y.
y scored less than 45 points.
y is less than 45
y < 45
Answer:
5 1/3 miles
Step-by-step explanation:
We can use a ratio to solve
8 miles x miles
------------ = --------
3 hours 2 hours
Using cross products
8*2 = 3x
16 = 3x
Divide by 3
16/3 = 3x/3
5 1/3 miles =x
Multiply both sides by 5 to go from this
x/5 >= -2
to this
x >= -10
The notation ">=" without quotes means "greater than or equal to"
To graph this, plot -10 on the number line as a closed circle. Shade to the right of this closed circle. The shaded region represents all the solutions to the original inequality.
Final Answer: Choice D
