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
Answer:
y=4
Step-by-step explanation:
first you that the number outside of the parenthesis and multiply it by the numbers inside 3x3y (ignore the y for right now) and 6x3 now we have 9y-18=18 now we move the 18 so the y is by itself now we have 9y=36 divide both by 9 and you get your answer y=4
45% of 76
45%=0.45
0.45*76
34.2
34.2 is about 34
so 34
Multiply the price by the 5% by turning the percent into a decimal.
5% = 0.05
45.90 x 0.05 = $2.295
Which can be rounded to 2.30 if needed.
