Hello :
<span>2x + 3 < 19 and 2x − 3 ≤ -7 :
the system :
</span><span>2x + 3 < 19 .....(1)
2x − 3 ≤ -7......(2)
by (1) : 2x </span>< 16
x < 8
by(2) : 2x ≤ -4
x ≤ -2
conclusion : x < 8 and x ≤ -2
The solution set is : x ≤ -2
Answer:
x = 93.4° ( to 1 dec. place )
Step-by-step explanation:
Given
cos(x - 46.7)° = 4 ( divide both sides by )
cos(x - 46.7)° = , thus
x - 46.7 = ( ) ≈ 46.7° ( add 46.7° to both sides )
x ≈ 93.4°
Answer:
110
Step-by-step explanation:
110/5 = 22
22 - 11 = 11
A. 48 / 12 = 4 24 / 6=4 Factory A should work 4 hours.
B. 48 / 8 = 6 24 / 4 = 6 Factory B should work 6 hours.
Hope this helps!
