Answer:
x=-2 x=1
Step-by-step explanation:
16x2 + 10x – 27 = -6x + 5
Add 6x to each side
16x^2+6x + 10x – 27 = -6x+6x + 5
16x^2 +16x -27 = 5
Subtract 5 from each side
16x^2 + 16x – 27-5 = 5 - 5
16x^2 +16x -32 = 0
Factor out 16
16 (x^2 +x-2)=0
Factor
16 (x+2) (x-1) =0
Using the zero product property
(x+2) =0 x-1=0
x=-2 x=1
Answer:
It takes Jane 2 2/3 minutes
It takes Joan 5 1/3 minutes
Step-by-step explanation:
let j = time it takes Jane
let 2j = time it take Joan
j + 2j = 8
3j = 8
j = 8/3 or 2/23
2j = 16/3 or 5 1/3
There are 8 letters and 3 of them is a vowel.
P(not consonant) = P(vowel) = 3/8
A is the correct choice.
