2x-py=5 and 4x+5y+q=0.
Mademuasel [1]

Answer:

q = 1 and p = 3

Step-by-step explanation:

Since we are already given the value of x and y, then it will be easy to get what p and q is. What is needed to be done is just to insert the values of x and y in both equations

For equation 1

2x -py = 5

insert x = q and y = -1

2(q) -p(-1) = 5

2q + p = 5

for the second equation, we do same

4x + 5y + q = 0

insert x = q and y = -1

4(q) + 5(-1) + q = 0

4q -5 + q = 0

5q = 5

q = 5/5 = 1

Recall from above, 2q + p = 5

Insert q = 1, we have ;

2(1) + p = 5

2 + p = 5

p = 5-2

p = 3

hannahs exercise goal is to walk at least 6 1/2 miles this week. she has already walked 2 3/4 miles this week. write and solve a
Ne4ueva [31]

We want to write an inequality that tells how much Hannah should walk this week. The inequality will be:

x ≥ (3 + 3/4) mi

<h3>Finding the inequality:</h3>

We know that she already did walk 2 3/4 miles this week, and she wants to walk at least 6 1/2 miles.

So to reach that minimum, she needs to walk:

(6  1/2)mi - (2 + 3/4) mi = (3 + 3/4) mi

And she can walk that or more, so the inequality is:

x ≥ (3 + 3/4) mi

Where x represents how much she will walk this week.
