Answer:
|-4a+10|=2 when a = 2 or a = 3.
Step-by-step explanation:
Your problem is a modular function problem
Modular function
The modulus of a value is the distance of the value to the origin.
It is quite helpful to start this kind of problem from a simple example.
|a| = b is if a = b or if a = -b. |x| = 2 if x = 2 or if x = -2. In both cases, the distance to the origin is 2.
So in your question, we have:
a = -4a + 10
b = 2
Now we have to apply both cases.
Solution 1: |a| = b if a = b
a = b
-4a + 10 = 2
-4a = -8 *(-1)
4a = 8
a = 2
Solution 1: |a| = b if a = -b
a = -b
-4a + 10 = -2
-4a = -12 *(-1)
4a = 12
a = 3
So, |-4a+10|=2 when a = 2 or a = 3.
51. is -150. you just minus 350 from 200
Answer:
Volume of 1 ball = 4/ 3 * pi* *r^3
=4/3 * pi* 1.25^3
=8.18 cu.in
3 balls volume = 8.18 *3
= 24.54 cu.in
empty space = 36.8 - 8.18= 27.68 cu.in

Answer:
100 inches (using the given data)
98.43 (using exact numbers)
Step-by-step explanation:
1 inch = 2.54 centimeters
20 inches = 50.8 centimeters, but for the purpose of answering this question we will assume that 20 inches = 0.5 meters (instead of 0.58).
we must solve the following equation:
20 inches / 0.5 meters = X inches / 2.5 meters
(2.5 meters x 20 inches) / 0.5 meters = X inches
20 inches x 5 = X inches
100 inches = X inches
if we do the exact calculation, 2.5 meters in inches = 250 centimeters / 2.54 centimeters per inch = 98.43 inches
