Answer:
B
Step-by-step explanation:
The two triangles are congruent because they have three rispective side congruent
AB and AD are both radiuses and AC is in common
so m arc BC is 78 degrees
It is 5 hours from 10:30am to 3:30pm.
6 large + 5 small = 127 kg ------------ (1)
2 large + 3 small = 51kg ------------ (2)
<u>(2) x 3 :</u>
6 large + 9 small = 153 ---------------- (2a)
<u>(2a) - (1) :</u>
4 small = 26
1 small = 6.5kg ------------ (sub into equation 1)
6 large + 5 small = 127 kg
6 large + 5(6.5) = 127
6 large + 32.5 = 127
6 large = 127 - 32.5
6 large = 94.5
1 large = 15.75 kg
Answer: The small box weighs 6.5kg and the big box weighs 15.75 kg
Given that the two triangles are similar:
=
=
6x + 28 = 4 x 25
6x + 28 = 100
6x = 100 - 28
6x = 72
x = 12
First, multiply each side by 5
6(x+1) = 25x-15
distribute the 6
6x+6=25x-15
put the x's on the same side and the other numbers on the opposite side
21=19x
Divide by 19 to isolate the x
21/19=x
