First thing you must do is square root both sides. This gives you:
1/3y + 2 = √121 which becomes 1/3y + 2 = 11 and 1/3y + 2 = - 11
This is because both 11 and - 11 when squared are equal to 121. So we must solve for both to find the solutions.
1/3y + 2 = 11
Subtract 2 from both sides to get 1/3y = 9
Now multiply both sides by 3 to isolate the variable y
3(1/3y) = 9(3) which becomes y = 27.
Now for the other equation 1/3y + 2 = - 11
Again, subtract 2 from both sides to get 1/3y = - 13
And multiply by 3 to isolate the variable y
3(1/3y) = - 13(3) which becomes y = - 39
Your answer: y = - 39, 27
Answer:
<em>1/15 cup</em>
Step-by-step explanation:
If you make 1/9 of the recipe, you use 1/9 of all ingredients.
1/9 of 3/5 cup =
= 1/9 * 3/5 cup
= 3/45 cup
= 1/15 cup
2 and 1/2 because 2 shots would be 50% and 3 would be 75% so it would have to be 2 and 1/2 shots.
Carbon is Carbon so it's just one atom.
Air is mostly O2, N2, H2O and ....
Salt is NaCl and not one atom ;)
Answer:
Place value is defined as the digit multiplied wherever it is placed, either by hundreds or thousands. Face value is simply defined as the digit itself within a number. Place value of a digit should be multiplied by the digit value of the position where it is located.
