4 5/12 you just add the fractions
Well I don't know !
Let's check out the choices:
A). 3a - 4b = 21, a=0, b=7
3(0) - 4(7) = 21
0 - 28 = 21 Nope. That's not true.
B). 3a - 4b = 21, a=-3, b=2
3(-3) - 4(-2) = 21
-9 + 8 = 21
-1 = 21 Nope. That's not right.
C). 3a - 4b = 21, a=-2, b=-3
3(-2) - 4(-3) = 21
-6 + 12 = 21
6 = 21 Nope. That's not it.
Only one choice left.
This one had better be it:
D). 3a - 4b = 21, a=7, b=0
3(7) - 4(0) = 21
21 - 0 = 21
21 = 21 Yay ! That's it !
Answer:
Step-by-step explanation:
Everything Shoes:
E * 0.8 = 115
E = 115/.8 = $143.75
~~~~~~~~~~~~~~~~
B * 0.15 = 7
B = 7/.15
B = $46.67
By using Pythagoras theorem.. the angle is 53 degree(rounded to the nearest angle).. so x degree =53 degree
Answer:
b and d
Step-by-step explanation:
b and d from the picture
same angle of 25 between sides with 1:2 side to base ratio
