Answer:
A
Step-by-step explanation:
Solving for x:
-3x + 8 ≥ 14
-3x ≥ 6
x ≤ -2
Notice the sign gets reversed when you divide or multiply by a negative number.
The only option less than -2 is -3, A.
Here's a tip: on multiple choice questions, sometimes it's faster to try each answer instead of solving the equation. This can save time on tests like the SAT or ACT.
Let's try it:
-3(-3) + 8 = 9 + 8 = 17
-3(-1) + 8 = 3 + 8 = 11
-3(0) + 8 = 0 + 8 = 8
-3(3) + 8 = -9 + 8 = -1
So you can see the answer is A.
Combine like terms.
10x+6=24+9x
Put variables to one side and the constants to another.
x=-18
There is only one solution.
Hope this helps!
Answer:
it is 50.27
Step-by-step explanation:
the formula for finding the area it
A= pi r^2
pi=3.14
so that being said you want to:
you want to divide the diameter by 2 to get 4,then you want to do 4^2 to get 16. then multiply 16 by 3.14 to get 50.265 then you want to round up to 50.27
Answer: 31.8
Step-by-step explanation:
We are given first coordinate (-2,5) and second coordinate (4, -5).
We need to find the coordinate of the half the distance.
Note: The mid-point coordinate is the coordinate of half the distance.
So, we need to find the mid-point coordinate of the given coordinates.
We know mid-point formula:
Plugging values of x1,y1 and x2, y2 in the above formula.
Mid-point = 
Mid-point = (1,0).
Therefore, (1,0) is the only coordinate of the point where fiona has run half the distance.
