14 hours per week
4 days per week
14/4 = 3.5 hours per day
Answer: First Option is correct.
Step-by-step explanation:
Since we have given that
Cost of per pound= $1.28
If a sack of cornmeal weighs = 4 pounds 12 ounces
First we need to convert ounces into pounds ,
as we know that ,
Now, total pounds of cornmeal is given by
Total cost for 4.75 pounds is given by
So, First Option is correct.
Answer:
6 weeks
Step-by-step explanation:
Jamal's total payment = 324
Payment per week = 54
No. of weeks (for completing payment) = w
So, 54w = 324
w = 324 / 54
w = 6 (weeks needed)
My teacher does the factor tree which is this

So that would be 2 * 5 * 5 or 2 * 5²
A. Alright, we want to multiply one equation by a constant to make it cancel out with the second. Since the first equation has a "blank" y, let's multiply the first equation by <em>2</em>.
3x-y=0 → 2(3x-y=0) = 6x - 2y = 0
5x+2y=22
The answer for this part would be: 6x - 2y = 0 and 5x + 2y = 22
B. So now we combine them:
6x - 2y = 0
+ + +
5x + 2y = 22
= = =
11x + 0 = 22 ← The answer
C. Now that we have the equation 11x = 22, we solve for x
11x = 22 ← Divide both sides by 11
x = 2 ← The answer
D. Now that we have x=2, we plug that back in to 5x+2y=22 and solve for y:
5(2)+2y = 22
10 + 2y = 22
2y = 12
y = 6
<u>Therefore, the solution to this problem is x = 2 and y = 6</u>
