Answer:
-13
Step-by-step explanation: hope this help
4x² - 9x² + 5 = 0
4x² - 4x - 5x + 5 = 0
4x(x - 1) - 5(x - 1) = 0
(4x - 5)(x - 1) = 0
Set each binomial equal to zero.
4x - 5 = 0
4x = 0 + 5
4x = 5
x = 5/4
x - 1 = 0
x = 0 + 1
x = 1
Your solutions are x = 1, 5/4

10 1/2 - 1 1/2 = 9
Ab-ac=a(b-c)
a is common factor
find common factor
factor the numbers
24=2*2*2*3
18y=2*3*3*y
common factor is 2*3 or 6
6(4)-6(3y)=6(4-3y)
Answer:
x < 15
Step-by-step explanation:
Emma's previous time was 1 hour 10 minutes. This is equal to
60+10 = 70 minutes.
She has already run 55 minutes; this means the remaining time, x, added to 55 must be less than 70 in order to beat her previous time:
x + 55 < 70
Subtract 55 from each side:
x + 55-5 < 70-55
x < 15
