Answer:
length= 24cm
Step-by-step explanation:
interpreting the question
L=3w
perimeter=2(l+w)
64=2(3w+w)
64=2(4w)
64=8w, Divide both sides by 8
w= 8cm
since w= 8
L=3w
L=3×8
L=24cm
Answer:
x = 18
m<A = 166°
Step-by-step explanation:
The parallel lines are cut by a transversal, so corresponding angles A and B are congruent.
7x + 40 = 3x + 112
4x = 72
x = 18
m<A = 7x + 40 = 7(18) + 40 = 126 + 40 = 166
-25 15/19 + 9/1
get a common denominator of 19
they multiplied 9/1 * 19/19 = 171/19
-25 15/19 + 171/19 =
change the mixed number to an improper fraction
(19* 25 +15)/19 = 490/19
-490/19 + 171/19 =
add together
-319/19
now convert the improper fraction back to a mixed number
19* 16 =304 319-304=15
-319/19 =-16 15/19
Divide 110 by 50 to get your answer, which would be 2.2. It would take 2.2 hours to get to your brother's house.
