Answer:
x - z = -36
Step-by-step explanation:
Given:
x + y y + z
---------- = 32 and ---------- = 50
2 2
These lead to x + y = 64 and y + z = 100
Subtracting the second equation from the first yields:
x + y = 64
-( y + z = 100)
------------------------
x - z = -36

Answer:
1/3
Step-by-step explanation:
We require the quantities to have the same dimensions.
Using the conversion
1 metre = 100 cm, then
2.1 m = 2.1 × 100 = 210 cm
The fraction can then be expressed as
70/210← divide numerator/ denominator by 70
= 1/3 ← in simplest form
200 beads ----> $48
1 bead -------> 48/200=6/25
25 beads ----> 6/25 x 25 = $6
==> total charge: 48+6= 54
