Answer:
the first one is b and the second one is 17 I think
to solve you do the mixed number (4) times the denominator (5) plus the numerator (3)
First, you must make sure that since the length is twice as big as the length. That means that the length would be 6.8 because 3.4 x 3.4 = 6.8. Then, since a rectangle has two long sides and two short sides, you add 6.8 + 6.8 + 3.4 + 3.4, which equals 20.4(perimeter).
1. $21 divided by 6m= $3.5
2. Take the $3.5 and multiply by 11m =38.5m
3. $28 divide by $3.5=8m
Answer:
180-63= 117
Step-by-step explanation:
the lines are parallel so the opposite of x is 63. it is a straight line so it adds up to 180
X= 12
5/2 x = 3/4 x + 21
7/4 x = 21
x = 12
