83

Step-by-step explanation:

82+87+83+77+70+80+88= 567

567/7= 81 so 83 was the missing number

Leni [432]

Since the recipe calls for 5 1/2 cups of flower and Molly only has 3 3/4 cups, subtract 3 3/4 from 5 1/2 to get the remaining cups of flour needed to make the recipe.

Describe how you would determine the x-intercepts from the factored form of a quadratic equation
Aloiza [94]

Answer:

Please check explanations

Step-by-step explanation:

Given the factored form, all we have to do is to equate each of the factor to zero, then solve for x

The particular value of x represents the solution that shows the value of the x-intercept

for example

In a case of a quadratic equation where we have

(x-a)(x-b) = 0

Then we can have

(x-a) = 0 or ((x-b) = 0

Then we have x = a or x = b

a and b are the x intercepts in this case

A total of $5000 is invested: part at 9% and the remainder at 14%. How much is invested at each rate if the annual interest is $
IceJOKER [234]

9514 1404 393

Answer:

  • $200 at 14%
  • $4800 at 9%

Step-by-step explanation:

Let x represent the amount invested at 14%. Then 5000-x is the amount invested at 9%. The interest earned is ...

  (14%)x +(9%)(5000 -x) = 460

  0.05x +450 = 460 . . . . . . . . . . simplify

  0.05x = 10 . . . . . . . . . . . . . . subtract 450

  x = 200 . . . . . . . . . . . . . . divide by 0.05

  5000-x = 5000-200 = 4800

$200 was invested at 14%; $4800 was invested at 9%.
