The main property is as follow
(A^p)^q=A^pxq
so only Sam's work is correct because
(8^4)^5 x(7^3)^9=(8^4x5)x(7^3x9)=8^20x 7^27
800 x 100 = 80000
80000 divided by 16 = 5000
5000 - 800 = 4200
His overall budget is $4200
Answer:
3x
Step-by-step explanation:
2y + 1 + x + ? = 2y + 1 + 4x
Subtract 2y from each side
2y -2y+ 1 + x + ? = 2y-2y + 1 + 4x
1 + x + ? = 1 + 4x
Subtract 1 from each side
1 -1+ x + ? = 1 -1+ 4x
x + ? = 4x
Subtract x from each side
x-x+? = 4x-x
? = 3x
Answer
X=117°
Step-by-step explanation:
Angle on a straight line =180°
101+y=180
y=180-101
y=79°
then: 38+79+z=180
z=180-38-79
z=63°
angle on a straight line=180°
63+X=180
X=180-63
X=117°
All the real number less than -3. It the first one hope this help
