Answer:
-21
28
Step-by-step explanation:
1) if r = -4
Substitute r = -4 in 3r - 9
= 3 * (-4) - 9
= -12 - 9
= -21
2) ( 4 / 7 ) * x = 16
4 * x = 16 * 7
x = 4 * 7
x = 28
Answer:
89.263 m I couldn't remember the easist way of doing this type of summation problem. I used brute force. a spread sheet would have been quicker

10 20(4/5)^9 2.684 89.263
add the results from each swing
I got 89.263 meters
Answer:(a) x - 0.7 = 1.5
Step-by-step explanation:
Determine whether each of the following is a solution of x − 0.7 = 1.5: (a) x = 1 (b) x = −0.8 (c) x = 2. Step 1. Substitute the number for the variable in the equation.
Step 2. Simplify the expressions on both sides of the equation.
Step 3. Determine whether the resulting equation is true.
If so, the number is a solution.
If not, the number is not a solution.
