The sentence "15% of 4x is 20 less than x"
translates to 0.15 • (4x) = x – 20
Solving that…
0.15(4x) = x - 20 multiplipy 0.15•4
0.6x = x - 20 subtract x from both sides
-0.4x = - 20 divide both sides by -0.4
x = 50
Answer:
<B = 50
Step-by-step explanation:
<B = <C = 50
Negative. If a negative number is "larger" (further away from zero) than a positive number, the result will be negative. You're basically subtracting a value that is greater than your starting value.
For example:
8 positive counters plus 18 negative counters:
This can be expressed as 8-18, which equals -10. The sign of the sum is therefore negative.
