HI! The answer to that is 60 marbles.
Answer:
option A and E
Step-by-step explanation:
Option A is equivalent because of the commutative law of addition;
(A + B) + C = A + (B + C)
option E is also correct because multiplication rule of inside the brackets.
A - ( - B - C) = A + B + C
4x + y = 54
8x + 2y = 104
8x + 8y - (8x + 2y) = 240 - 104
6y = 136
y=22 2/3
4x+ 22 2/3 = 54
4x= 31 1/3
x= 7 5/6
I believe it is 5+15c first box and the second box is 1/8 - 4/4c
1/15=8/x
x=8*15
x=120
The actual length of the dinosaur's tail is 120 in.
1/380=x/3420
3420/380=x
x=9
The height of this mountain on map would be 9 inches.
