I would say D, determine if it can be factored by grouping (sorry, I forgot to put in the answer here).
1. distribute a 1 to the 12 and 8a
2. you'll get 15+ 12 +8a
3. add the like terms(15 and 12)
4. your final answer will be 27+8a
scientist A dissolved 1 kg of salt in 3 litres.
scientist B dissolved 20 pounds of slat in 7 pint of water.
we know that 1 pound =0.543 g
20 pounds=9.07 kg.
1 pint=0.5 litres
so 7 pints =3.5 litres
so dissoving 1 kg of salt in 3 litres of water and 9.07 kg in 3.5 litres of water
we know that for concentration kg/l units is used .
for A= 1/3=0.33kg/l
and B=9.07/3.5=2.59 kg/l.
so scientist A has prepared more concentrated solution .
11,340 I believe. 5% of 8400 is 420. 420*7=2940 2940+8400=11340
Answer:
The solution to the inequality is:
The solution graph is also attached below.
Step-by-step explanation:
Given
We are given the expression
To determine
Solve for x
Given the expression
Subtract 5 from both sides
Simplify
Multiply both sides by 3
Simplify
Thus, we conclude that:
Therefore, the solution to the inequality is:
