The answer is -100. This is because 50 x 4 = 200 and -300+200=-100

When renting a limo for prom, the number of people is inversely proportional to the cost per person. Originally there were 5 peo
Oksana_A [137]

Answer: The cost per person would be $15.20.

Step-by-step explanation: The price $40 per person when you have 5 people, is 8,8x the price per person. So, if you have 6 people more, you have 8,8x6 less in the price.

8,8 x 6 = 52,80.

44 x 5= 220,00. That was the cost for the limo for 5 people.

It means 220,00 - 52,80 = 167,20 (new price for 11 people)

167,20 ÷ 11 (new price per person) = 15,20.

PLEASEEEEEE Which system of equations does not have a real solution? y = x 2 + 3 x - 5 and 4 x + 5y = 20 y = x 2 + 3 x - 5 and x
Delicious77 [7]

Answer:

\Large \boxed{y = x^2  + 3 x - 5 \ \ \mathrm{and} \ \  x + y = -10}

Step-by-step explanation:

y = x² + 3 x - 5 and x + y = -10 are the system of equations that do not have a real solution.

When the two equations are graphed and if they do not intersect, then there are no real solutions for the system of equations.

Find the radius of a circle with a circumference of 39 yards. Round your answer to the nearest hundredth of a yard.
eduard

Answer:

The radius of the circle is 6.20 yards

Step-by-step explanation:

In this question, we are asked to calculate the radius of a circle with a circumference of 39 yards.

Mathematically, the circumference of a circle can be calculated using the formula;

C = 2 π r

Hence;

39 = 2 * 22/7 * r

7 * 39 = 2 * 22 * r

273 = 44r

r = 273/44

r = 6.2045 which is 6.20 yards to the nearest hundredth of a yard

Henry is following the recipe card to make a cake. He has 95 cups of flour. How many cakes can Henry make?
ahrayia [7]
For one cake alone, find a common denominator (which is 6). So 2 2/3 (8/3) is equal to 16/6 cups. 1/2 is 3/6 cups. So for one cake, it takes 19/6 cups of flour. Henry has 570/6 (=95) cups of flour. If you divide the 570 by 19, Henry can make 30 cakes.
