Let’s let the number of nickels be x. Then the number of dime must be 33-x.then 5x+10(33-x)=240 5x+330-10x=240 330 5x=240 x5=90x=18
Find the mean for the given set of data.
-4, -3,-1,-1, 0, 1
-1 1/3
-1
-3/4
Answer is -1 1/3
Answer:5
Step-by-step explanation:
Because it’s the right answer
Q is congruent to P because they’re both got the same x and y number the x is 5 and -5 and for y is 3 and -3.
Answer:
5X + 8Y >= 300; intersection at (-20, 50)
Step-by-step explanation:
let t = work hours
0 < t < 30
X = time lawn mowing
Y = time babysitting.
X + Y < 30
5X + 8Y >= 300
We could solve...
X < 30 - Y
5(30 - Y) + 8Y >=300
150 - 5Y + 8Y >= 300
3Y >=150
Y >=50
then X < -20
intersection at (-20, 50)
