Answer:
x = 1/2
Step-by-step explanation:
<em>Simplify the sides of the equation...</em>
<em>10x + 3 = 4x + 6</em>
<em>Subtract 3 from both sides...</em>
<em>10x = 4x + 3</em>
<em>Subtract 4x from both sides...</em>
<em>6x = 3</em>
<em>Divide by 6</em>
<em>x = 1/2</em>

Answer:
She used 4 test tubes for the last experiment
Step-by-step explanation:
Total test tubes needed = 14
Experiment 1 = 2 test tubes
Total test tubes remaining = total - used
= 14 - 2
= 12 test tubes
Remaining experiment = 4 - 1
= 3
Test tubes used for the remaining experiment = test tubes remaining / Experiment remaining
= 12 / 3
= 4 test tubes
How many test tubes did she use for the last experiment?
She used 4 test tubes for the last experiment
