Mathematics
1 answer:
muminat3 years ago
5 0

Answer

a=  −bx−c  / x2

Step-by-step explanation:

ax2+bx+c=0

Step 1: Add -bx to both sides.

ax2+bx+c+−bx=0+−bx

ax2+c=−bx

Step 2: Add -c to both sides.

ax2+c+−c=−bx+−c

ax2=−bx−c

Step 3: Divide both sides by x^2.

ax2

x2

=

−bx−c

x2

a=

−bx−c

x2

six times jasons collection of books and one-third of nathans collection add up to 134 books one-third of jasons collection and
atroni [7]
6j + 1/3n = 134...multiply by 3....18j + n = 402
1/3j + n = 31....multiply by 3....j + 3n = 93

the multiplying by 3 is optional...I just did it because it is easier to work with equations when there are no fractions.

18j + n = 402....multiply by -3
j + 3n = 93
----------------
-54j - 3n = - 1206 (result of multiplying by -3)
j + 3n = 93
----------------add
-53j = - 1113
j = -1113/-53
j = 21

j + 3n = 93
21 + 3n = 93
3n = 93 - 21
3n = 72
n = 72/3
n = 24

so Jasons collection (j) consists of 21 books and Nathans collection (n) consists of 24 books

Luis es repartidor de leche el tiene 534 bolsas y las reparte entre cierto numero de tienda de modo que a cada le corresponde 28
OlgaM077 [116]
The first thing we must keep in mind is that there are 2 bags left over.
 Therefore, Luis distributed:
 534-2 = 532
 The number of bags will be:
 N = (total amount distributed) / (amount distributed per store)
 Substituting we have:
 N = (532) / (28)
 N = 19
 Answer:
 
Luis distributed milk for 19 stores.
