Answer:
Step-by-step explanation:
Given the quadratic inequality we are to find the interval of x
x² − 8x + 15 < 0
Factorize
x²-3x-5x+15<0
x(x-3)-5(x-3)<0
(x-3)(x-5)<0
(x-3)<0 and x-5<0
if x+3<0
x<-3
If x-5<0
x<5
Hence the solution yo the quadratic inequality are x<3 and x<5
Hence
If you are just looking for any number between you can go from 144.810 to 145.154 and you can get even more number if you add a zero to both number because there are lots more between 145.1550 and 144.8090
However, if you are looking for the number that is equidistant between them - the number in the middle, simply add them together and find the average which will be the number in the middle.
So
(145.155 +144.809)÷ 2 = 144.982
Answer:
the price for each doughnut is $1.05
Step-by-step explanation:
doughnuts = d
cookies = c
2d + 3c = $3.30
5d + 2c = $4.95
to find the answer multiply 2 with the first equation, and multiply -3 with the second equation.
4d + 6c = 3.30
-15d - 6c = -14.85
combine like terms
-11d = -11.55
divide by -11
d = 1.05
