Answer is D
Answer:
Beth is five years old.
Step-by-step:
Beth + Julio + Gerald + Debra = 38
B + (Beth - 2) + (2 x Beth) + (2 x Gerald) = 38
Since we know that Gerald is twice as old as Beth and Debra is twice as old as Gerald. That makes Debra four times older than Beth.
Beth + (Beth - 2) + (2 x Beth) + (4 x Beth) = 38
B + (B -2) + (2B) + (4B) = 38
Simplfy the like terms.
8B - 2 = 38
Add 2 on both sides.
8B = 38 + 2
8B = 40
Divide both sides by 8 to isolate the variable.
8/8 B = 40/8
B = 5
Answer:
Step-by-step explanation:
49t^4-25
(7t^2-5)(7t^2+5)
Y= -120/2x+360
-120/2 can be simplified to -60 which becomes the slope
answer: y= -60x+360 where -60 is th slope
Answer:
Step-by-step explanation:
1 ft = 12 in
6 ft 8 in = 6*12 + 8 = 72 + 8 = 80 in
Scale factor = 80 : 5
= 16 : 1
