Answer:
Given the following information, your system of equation is going to be...
x + y = 250
15x + 20y = 4250
Step-by-step explanation:
So, in the problem, we are given important key details that can help us solve it.
- x = number of $15 packages sold
- y = number of $20 packages sold
- The school collected $4250 from sales
- 250 packages were sold in total
Now that we have this information, we can solve the problem. Since 250 packages were sold in total, then you are going to add x and y. Since the school collected $4250 from the sales, then you are going to be adding 15x and 20y together.
So, to conclude, your answer is going to be the first answer choice.
Answer: 22 2/3 feet
Step-by-step explanation:
From the question, a concrete company pours 8 sections of sidewalk each of which is 2 5/6 feet long. The length of the entire sidewalk that the concrete company pours will be calculated by multiplying 8 by 2 5/6 feet. This will be:
= 8 × 2 5/6
= 8 × 17/6
= 136/6
= 22 2/3 feet
Answer:
y = .75x - 4.5
Step-by-step explanation:
y = mx + b
m = slope ; b = y-int
slope = rise/ run = 3/4 = .75
y = .75x + b
Because it is hard to determine the exact y-intercept, we plug in a point (2,-3):
-3 = .75(2) + b
-3 = 1.5 + b
-4.5 = b -->
y = .75x - 4.5
Answer: Yes
