Answer:
Step-by-step explanation:
-2x² + 12x + 32 = 0
discriminant = 12² - 4(-2)(32) = 400
positive discriminant means there are two distinct real roots
x = [-12 ± √(12² – 4(-2)·32)] / [2·(-2)]
= [-12 ± √400] / (-4)
= [-12 ± 20] /(-4)
= 8, -2
Answer:
800
Step-by-step explanation:
0℅ decrease of 800=800
Answer:
the cost of one package of chocolate chip cookie and one package of ginger bread is $6 and $18 respectively
Step-by-step explanation:
The computation of the cost of one package of chocolate chip cookie and one package of ginger bread is shown below:
Let us assume the package of chocolate chip cookie be x
And, the package of ginger bread is y
So,
According to the question
6x + 2y = $72
6x + 10y = $216
Now subtract equation 1 from equation 2
-8y = -144
y = $18
And, for x it would be
6x + $36 = $72
x = $6
Hence, the cost of one package of chocolate chip cookie and one package of ginger bread is $6 and $18 respectively
Answer:
$350
Step-by-step explanation:
7*10=70
Multiply by cost
70*5=350
their are 3 ways 1:3 1/3 and 1 to 3 these are equivalent ratios
