Answer:
x = 15, Angles are both 130!
Step-by-step explanation:
Since this is an example of Alternate Exterior Angles, you could set these equal to eachother!
9x-5 = 7x + 25
-7x -7x
Subtract 7x from both sides.
2x - 5 = 25
+5 +5
Add 5 to both sides.
2x = 30
Divide by two to get x by itself .
x = 15, now you can plug this in for X and get the angle
9(15) - 5 = 130
Answer:
Since this is an example of Alternate Exterior Angles, you could set these equal to each other! its 125

Answer:
Top: x=1, y= -2
Bottom: x= 6, y= -6
Step-by-step explanation:
Top:
Isolate x for y: 2(3+y) + y = 0
Simplify: 6+3y=0
Isolate y for 6+3y=0: y = -2
For x= 3 + y: x = 1
Bottom:
Isolate x for : -4x - 2y= -12: x= [tex]\frac{-6 + y}{2}[/tex]
Simplify: 6y+ 12 = -24
Isolate y for 6y+ 12 = -24: y = -6
For x= [tex]-\frac{-6 -6 }{2} = 6[/tex] : x = 6

Answer:
B.
Step-by-step explanation:
A.
Income: 600,000 + 600,000 + 400,000 =
$1,600,000
Expenses: 400,000 + 500,000 + 600,000 =
$1,500,000
B .
Expenses: 600,000 + 700,000 =
$1,300,000
Income: 400,000 + 600,000 =
$1,000,000
1,300,000 - 1,000,000 = $300,000
C.
Expenses:
Year 1: 400,000
+ 100,000 =
Year 2: 500,000
+ 100,000 =
Year 3: 600,000
+ 100,000 =
Year 4: 700,000
+ 100,000 =
Year 5: 800, 000
Adds 100,000 each year not 200,000.
D.
Income:
Year 1: 600,000 x 2 =
$1,200,000
Year 5:
$900,000
Answer:
The combined expenses in Years 3 and 4 were $300,000 more than the combined income of Years 3 and 4.
Step-by-step explanation:
The combined income in years 1, 2, and 3 is $1,400,000 and the combined expenses in the same years is $1,500,000; so number 1 is incorrect.
Expenses have increased $100,000 each year over the last 5 years. Year 1 = $400,000 , Year 2 = $500,000 , Year 3 = $600,000 , Year 4 = $700,000 , Year 5 = $800,000. So number 3 is incorrect.
Year 1's income was $600,000 and Year 5's income was $900,000. Twice Year 1's income would have been $1,200,000. So number 4 is incorrect.
