Answer: the no.s are-
2.472
-6.472
Step-by-step explanation:
xy=24-----1
x+y=-4------2
from 2 we get x=-4-y
sustituting=
into 1 we get
quadratic eq = y^2 + 4y + 24=0
so
-4+- root 16-96/2
thus on further solving we get -2 +-4.472
on adding= -2+4.472= 2.472
on subtraction= -2 -4.472= -6.472
P=number of pens
h=number of highlighters
p+h=8
1.09h+0.69p=752
p+h=8
minus h from both sides
p=8-h
sub that for p
1.09h+0.69(8-h)=7.52
1.09h+5.52-0.69h=7.52
0.4h+5.52=7.52
minus 5.52 from both sides
0.4h=2
divide both sides by 0.4
h=5
sub back
h=8-p
5=8-p
minus 8 frm both sides
-3=-p
mltiply both sides by -1
3=p
3 pens you bought
I’m not entirely sure if i got this right but i think the answer is $603 dollars in total for the baker
Answer:
