Answer:
15 3/10 years
Step-by-step explanation:
Ballio age = 12 4/5
Bill's age = Ballio's age + 1 1/6
Bills age = 12 4/5 + 1 1/6 = 64/5 + 7/6 = (384 + 35) / 30 = 419 / 30 = 13 29/30
Jane's age :
13 29/30 + 1 1/3
419 / 30 + 4 /3 = (419 + 40) / 30 = 459 / 30 = 15 9/30
15 9/30 = 15 3/10 years
Answer:
18 ounces of barley
Step-by-step explanation:
If Meg uses barley and wheat flour in a ratio of 2:3, we can set up equivalent ratios in order to find how many ounces of barley Meg would need if she uses 27 ounces of wheat flour:
= =
We can solve for 'x' (the number of ounces of barley) using a few different methods. We can cross-multiply and divide: 27(2) = 3x, or x = 18. We can also see what factor we multiply the 3 by to get 27 and multiply the numerator (2) by the same number. Since 3 x 9 = 27, then 2 x 9 = 18.
<span>y = −4x2 + 2x − 1 not sure but hope this helps :)</span>
