Answer:

n=4

Step-by-step explanation:

5n+34=-2(1-7n)

1. So first expand.

5n+34=−2+14n

2 Regroup terms.

5n+34=14n−2

3 Subtract 5n from both sides.

34=14n−2−5n

4 Simplify  14n-2-5n to  9n-2.

34=9n−2

5 Add 22 to both sides.

34+2=9n

6 Simplify  34+2 to 36.

36=9n

7 Divide both sides by 9.

36/9=9

​​

8 Simplify 36/9 to 4

4=n

9 Switch sides.

n=4

Evaluate 7 + (-3x^2) For x = 0<br><br>A. -2<br>B. 0<br>C. 4<br>D. 7​
Goryan [66]

Answer:  D. 7

Step-by-step explanation:

The problem tells you that x = 0 so replace everything that is x in the equation with 0 so the problem becomes

7 + (-3(0)^2)

Now we just solve the problem normally.

solve the problem in the parenthesis first, we must multiply -3 times 0^2 is 0

so now our problem is 7 + 0 which is 7

=3 + 4/12 + 3/12

Step-by-step explanation:

To make 1/3 into a twelfth, you have to multiply the 3 by 4 to get 12. Whatever you do to the top you have to do to the bottom, meaning that you have to multiply 1 by 4 to get 4 on top.

A car dealership decreased the price of a certain car by 4%. The original price was
serg [7]
%change=100(final-initial)/initial, 

%change=100(New price-Original price)/Original price

(Original price*%change)/100=New price-Original price

New Price=(Original price*%change+100*Original price)/100

New Price=Original price(100+%change)/100

Since %change is -4%...

New Price=0.96(Original price)

...

Since original price is $45400

New Price=0.96(45400)

New Price=$43584

What is the length of side DG?<br><br><br> 12 in.<br><br> 32 in. <br><br> 36 in. <br><br> 30 in.
taurus [48]

Answer:

36 in

Step-by-step explanation:

The ratio of proportionality between the two similar triangles is 1:6, which you can find by dividing the corresponding side length measures from each triangle (3/18 = 4/24). Then you can set up a proportion:

1/6 = 6/x, which you can solve to get x = 36
