<span>4a) 1000 milliliters = 1 liter, thus 3 liters = 3 x 1000 = 3000 milliliters.
Thus Ed bought 3000 - 2750 = 250 more water than sports drink.
Therefore,
Ed bought 250 milliliters more water than sports drink is True.
4b) Ed bought 3 - 2.25 = 0.75 more water than juice.
Therefore, Ed bought 1.25 liters more water than juice is False.
4c) Ed bought 2.25 liters = 2.25 x 1000 = 2250 milliliters of juice.
Thus, Ed bought 2750 - 2250 = 500 more sports drink than juice.
Therefore, Ed
bought 50 milliliters more sports drink than juice is False.
4d) Ed bought 2750 milliliters = 2750 / 1000 = 2.75 liters of sports drink.
Ed bought 2.75 - 2.25 = 0.5 liters more sports drink than juice.
Ed
bought 0.5 liter more of sports drink than juice is True.
4e) Ed bought 3000 milliliters of water and 2250 milliliters of juice.
Ed bought 3000 - 2250 = 750 more milliliters of water than juice.
Therefore, Ed
bought 75 milliliters more water than juice is False.</span>
Answer:
x - 36 ≥ 55

x is the total amount of money earned. You subtract 36 from x because that's the amount of her expenses. The answer has to be either equal to or greater than 55 since she wants to make at least $55 per day.
Answer:
134.375 or 134 3/8 square feet is the area of the rug
Step-by-step explanation:
In this question, we learnt someone bought rug measuring some lengths per sides were asked to help calculate the area of the rug.
Firstly, we can see that the lengths of the two sides differ? We can thus conclude that the rug is rectangular in shape.
Hence, to calculate the area of this rug, what we do is to calculate the area of the rectangle formed by the rug.
Mathematically, the area of the rug would be = l * b
According to the question, we can identify that l = 10.75 feet(3/4 = 0.75) while the b = 12.5 feet(1/2 = 0.5 feet)
Hence the area of the rug A is thus; 10.75 * 12.5 = 134.375 sq. Feet ( 0.375 = 3/8 so we can say 134 3/8 feet)
Answer:
x = -4, y = 8.
Step-by-step explanation:
Question 16.
8x + y = -24 ........(A)
-3x - 2y = -4 ........(B)
Multiply (A) by 2:
16x + 2y = -48 Adding this to equation (B):
13x = -52
x = -4
Substituting this value of x in Equation (A):
8(-4) + y = -24
y = -24 + 32 = 8.
