-(x+2) = -5
divide by -1 to get rid of negative
(x+2) = 5
subtract 2 from both sides
x=3

Answer:
1 marble
Step-by-step explanation:
The volume of steel is ...
V = LWH
V = (30 cm)(20 cm)(10 cm) = 6000 cm³
The volume of a marble is ...
V = (4/3)πr³ = (4/3)π(11.273 cm)³ = 6000 cm³
The block of steel will make 1 marble.
Answer:
-6
Step-by-step explanation:
f(x) = -x-1
Find f(5), <u><em>this means that anywhere you see </em></u><u><em>x</em></u><u><em>, you substitute in </em></u><u><em>5</em></u><u><em>.</em></u>
f(x) = -x-1
f(5) = -(5)-1
<u>Take note of the signs.</u>
f(5) = -6
PLease rate 5 stars, give brainliest and thank. Thanks.
