Let janes age be x
let Harvey's age be 3x (as three times old as jane)
x+3x=48
4x=48
x=48/4
there fore x= 12
janes age= 12
Harvey's age = 3x
=3*12
=36
Answer:
A= 65 C= 65 and D= 115
Step-by-step explanation:
given a parallelogram .
interior angles sum is 360 degree.
sum of adjacent angles is 180degree.
opposite angles are congruent (B=D).
A + B + C + D = 360
(A + D) + C + 115 = 360 since A and D are adjacent angles .
180 + 115 + C = 360
295 + C = 360
C = 360 - 295
C = 65
D = 115
A = 65
a+b+c+d=360
65 + 65 + 115 + 115 = 360
130 + 230 = 360
360 = 360
3 minutes
10*8*12=960 cubic inches
960/320inches per minute =3
1.805>1.803
0.757>0.393
0.99<0.990
A trick is looking at each decimal place is looking from left to right and seeing which number has the most value
