Answer:
w = 4
Step-by-step explanation:
distribute 10(w+3)=70
10w + 30 = 70
subtract 30
10w = 40
divide by 10
w = 4
(1)4x + 3> 15 or -6x>=12
4x+3>15, subtract 3 on both sides (4x> 12) and then divide both sides by 4
x > 3
-6x>=12, divide both sides by -6 , so x<=-2
x>3 or x<=-2
The middle graph satisfies the above inequality
(2) -8x>-24 and -10<=2x-6
-8x>-24 , divide both sides by -8 , so it becomes x < 3
-10<=2x-6, add both sides by 6 , -4<=2x . then divide both sides by 2
x >=-2
x>-2 and x<3
The last graph satisfies the above inequality
-29<=9x-2<16
Add both sides by 2 and then divide both sides by 9
-27 <= 9x < 18
divide both sides by 9
-3 <= x < 2
x lies between -3 and 2
The first graph satisfies the above inequality
Answer:
m<1 = 162° , m<2 = 18°
Step-by-step explanation:
m<1 + m<2 = 180°
6x + x - 9 = 180°
7x - 9 = 180°
7x = 180 + 9
x = 27
Answer:
The Battle of Gettysburg, fought from July 1 to July 3, 1863, is considered the most important engagement of the American Civil War. After a great victory over Union forces at Chancellorsville, General Robert E. Lee marched his Army of Northern Virginia into Pennsylvania in late June 1863.
18+17 or 18+ (8+9)
