Step-by-step explanation:
(a)
10x - 45 ← factor out 10 from each term
= 10(x - 4.5)
(b)
- 2x + 3 ← factor out - 2 from each term
= - 2(x - 1.5)
(c)
- x + 4 ← factor out - 1 from each term
= - 1(x - 4)
(d)
- x - 19 ← factor out - 1 from each term
= - 1(x + 19)
Ok ummm I honestly don’t know I’m so sorry I couldn’t help you wit this prob
Answer:
x=-4
Step-by-step explanation:
F = first angle
s = second angle
t = third angle
a) f = 3 * s
b) t = s -35
c) f + s + t = 180
c) 3*s + s + (s-35) = 180
5s = 215
second angle = 43 degrees
first angle = 43*3 = 129 degrees
third angle = (43-35) = 8 degrees
