Answer:
-5 ,0,5
Step-by-step explanation:
x^2 ≤ 25
Take the square root of each side
sqrt(x^2) ≤ sqrt(25)
sqrt (25) is +5 and -5
x ≤ 5 and x ≥ -5
-5 ≤x ≤ 5
The choices are -5 ,0,5
Answer & Step-by-step explanation:
1.5 litres = 1500ml
<u>Small Milk Carton</u>
300ml x 5 = 1500ml
£1.20 x 5 = £6
<u>Large Milk Carton</u>
500ml x 3 = 1500ml
£1.40 x 3 = £4.20
The best value for 1.5l (1500ml) is to purchase 3 large milk cartons, as it's cheaper (by £1.80) than buying a small milk cartons.
Answer:
D. 75(5r+3d+4f) and 75(5r)+75(3d)+75(4f)
Answer:
y = 80-16x
Step-by-step explanation:
She made a total of 80 cups and sells 16 cups per hour
So in x hours she would have sold 16 * x = 16x cups
So the number of cups remaining will be;
y = 80-16x
Answer:
850 red beads
Step-by-step explanation:
One way to do this problem is to set a proportion.
red beads/red beads = total beads/total beads
Let x = the no. of red beads in the bag
x/17 = 7500/150
x = 17(7500)/150 = 850 red beads
