For this case we have the following expression:

We eliminate the parentheses taking into account that:

We add similar terms:

Different signs are subtracted and the sign of the major is placed:

Finally, the expression is reduced to:

Answer:

Option B
We need the figure to answer that.

Answer:
Step-by-step explanation:
A company manufactures two types of fishing rods, standard and folding. The cost of manufacturing 2 folding rods and 1 standard is $35. If 5 standard and 7 folding rods were manufactured, the cost would be $145. How much does it cost to manufacture each type of rod.
let S = standar rod
F= folding rod
2F + S =35
2F + S -2F =35 - 2F
or S = 35-2F
7F + 5S =145
7F + 5S -7F =145 -7F
or 5S =145-7F
Since S=35-2F
5S = 5X (35-2F)
5S = 175 -10F
which equals 145-7F
175-10F = 145-7F
175-10F +10F = 145 -7F + 10F
175 = 145 +3F
175 -145 =145 -145 + 3F
30 = 3F
F = 10
but S =35 - 2F
so S = 35 -2X10
S = 35-20 =15
check:
if F = 10 and S = 15
then 5S +7F should equal 145
5X15 + 7X10 = 75 + 10 =145
so F=10, S=15
Answer:
Step-by-step explanation:
Fist let's have a look :
- (AB) is parallel with (CD) and there is a line crossing them both.
Now the first question : What is the size x ?
- We notice that x and 53° are vertically opposite so they are corresponding angles
- so the size of x is 53°
The second question : what is the size of y ?
- We notice that y and 53° are alternate angles
- so they are corresponding angles with same size
- y=53°
The trick is to khow the situation where we have corresponding angles
