Okay, 72 degrees is equal to (5x-98), so
72=5x-98
5x=170
x=34
So now that we know that x=34, we can put 34 into (5x-98), so 170-98
170-98 and y are supplementary, so they add up to 180 degrees. So the equation is
170-98+y=180
72+y=180
y=180-72
y=108
Answer:
anwser y=3x-6
Step-by-step explanation:
B
You would divide 45 mm/15mm to get 3. Multiply 3 by 27 to get 81 mm.
Answer:
(1 - 2n)^3 equals
(1 -2n) * (1 -2n) * (1 -2n)
Step-by-step explanation:
Answer:
9 Model As.
Step-by-step explanation:
Let A represent Press A and let B represent Press B.
So, they own 14 total presses. This means that:

They can print 905 books per day, in other words, since A prints 70 per day and B prints 55 per day:

This is now a system of equations. Solve by substitution. From the first equation, subtract B from both sides:

Substitute this into the second equation: "

First, we can divide everything by 5 to simplify things:

Distribute the left:

Combine like terms:

Subtract 196 from both sides:

Divide both sides by -3

So, the company has 5 Model B presses.
Which means that the company has 14-5 or 9 Model A presses.
And we're done!
