Answer:
A:B:C = 35:28:30
Step-by-step explanation:
(Idk if it is the correct process but I remember doing it like this)
First...
4A = 5B
or, A/B = 5/4
= 5×7/4×7
= 35/28
Next...
6B = 7C
or B/C = 7/6
= 7×5/6×5
= 28/30
(Since there are two Bs which are 4 and 7, we divided it like 4×7 and 7×4 so they would be equals since both Bs should have same value. So we need to divide both denominator and numinator with same number.)
so...
A:B:C = 35 : 28 : 30

Answer:
x = 4 units
Step-by-step explanation:
2/z = z/6
z² = 12
z = 2√3
using the Pythagorean theorem:
x² = 12 + 2²
x² = 16
x = 4

Answer:
d = -10
Step-by-step explanation:
