Answer:
0.71875
Step-by-step explanation:
P(x) = (x + 3)Q(x) + R
<span> P(-3) = (0)Q(x) + R </span>
<span>i P(-3) = R </span>
<span>Now, P(-3) = (-3)⁴ - 9(-3)³ - 5(-3)² - 3(-3) + 4
</span>So
<span>P(-3) = 81 + 243 - 45 + 9 + 4 </span>
<span>=. 292

The answer to the question is 0.7
A. 38
Let X = seventh graders
6th graders are twice the number of 7th graders; therefore, 6th graders will be 2X.
The total number of students is 57.
2X + X = 57
3X = 57
X = 57 / 3
X = 19
IF X represents the 7th graders; there are 19 seventh graders present.
Since 6th graders are represented by 2X; Then, 2 * 19 = 38 is the number of 6th graders present.
Add both numbers to check: 19 + 38 = 57.
Answer:
First you need to multiply 3/8 by 5 to get the total amount of flour that there is. You should get 1.875 pounds.
Then you need to divide 1.875 by 7 to get the amount of flour per loaf of bread. You should get 0.26785714285 or 0.27 lbs of flour per loaf of bread.
