Answer:
answer is $28.87
Step-by-step explanation:
Okay -
So, the goal when we have an equation is to find the value of the variable. So, let's isolate that variable on <em>one </em>side of the equation!
<em>* original equation </em>
<em>5x + 4 = 49.
</em><em>* subtract four from both sides. if you do something on one side of the equation, you have to do it on the other.
</em><em>5x + 4 - 4 = 49 - 4.
* now we are going to divide 5 on both sides to isolate x.
5x/5 = 45/5.
* and our answer is...
x = 9. =)

Answer: 15 feet
Step-by-step explanation:
First you start with 2ft and 6in and convert it all into into inches.
If you know that 1 ft=12in then you know that 2 feet is the same as saying
12+12=24. If you don't understand use this chart-
1 ft=12in
2ft= 24in
3ft= 36in
4ft =48in
5ft= 60in
6ft= 72in
see I am counting by 12's.
Now take 2ft and convert it into inches. That would be 24 in (look in the chart).
now take the 24in(2ft) and add it to the 6in. So 24+6 =30
So now you know that one piece of pipe is 30in long.
But in the text it states that Don has 6 pieces, so...
because it says that he has 6 pieces of pipe then you are going to take that and multiply that number(6) by how long each piece is. look up and it shows how long each pieces is. They are all each 30in long. Take 30 and multiply that by 6 because there are 6 pipes and you will get 120in.
But it says that they need an answer of feet and inches or just feet if it exactly a some sort of foot like 43feet or 2 feet.
So then we are going to convert 180 into feet by dividing 180 by 12 and you get 15. So the answer is 15.
I hope this helps. Have fun learning!!
Answer:
Yes,they are congruent.
Step-by-step explanation:
We are required to make two transformations and prove that they are congruent.
First Transformation:Now rotate the polygon FGHIJ by 90° about the axis parallel to x-axis and passinfg through the vertex I.You can observe that the sides are of same length AB=GF=2 units.
Second Transformation: Keeping the polygon ABCDE constant shift the centre of polygon FGHIJ to the centre of polygon ABCDE you will observe thta they exactly overlap on each other hence they are congruent with each other.
