Answer:

f = 1

Step-by-step explanation:

-f + 2 + 4f = 8 - 3f

First, I'll add like terms.

2 + 3f = 8 - 3f

Then, I'll add 3f on both sides.

2 + 6f = 8

Next, I'll subtract 2 on both sides.

6f = 6

Finally, I'll divide 6 on both sides.

f = 1

Therefore, f = 1.

zvonat [6]

Answer:

x = 8

B = 70

Step-by-step explanation:

Given

A = 8x + 6

B = 4x + 38

Require

Determine x and <B

Missing in the question: A and B are vertical angles

For vertical angles A and B,

A = B

Substitute values for A and B

8x + 6 = 4x + 38

Collect Like Terms

8x - 4x = 38 - 6

4x = 32

Solve for x

x = 32/4

x = 8

To solve for B, substitute 8 for x in B = 4x + 38

B = 4 * 8 + 38

B = 32 + 38

B = 70

anne buys used cars at auction for 2000 per car. there is 150 fee to take part in the auction. If anne buys 13 used cars how muc
katrin [286]
How to understand the problem is like this:
   Total Cost = Entrance Fee + Total Car cost
So we know that the Entrance Fee is $150...
   Total Cost = $150 + Total Car cost
So we know that Anne bought 13 cars, each at $2,000...
   Total Cost = $150 + ($2,000 x 13)
We multiply because each car is $2,000 and Anne bought 13 of them.
So it works out like this:
   Total Cost = $150 + ($2,000 x 13)
   Total Cost = $150 + (26000)
   Total Cost = $26150
