x - 3y = 1 ⇒ 3x - 9y = 3
3x - 5y = 11 ⇒ 3x + 5y = 11
-14y = -8
-14 -14
y = ⁴/₇
x - 3y = 1
⁴/₇ - 3y = 1
- ⁴/₇ - ⁴/₇
-3y = ³/₇
-3 -3
y = ⁻¹/₇
(x, y) = (⁴/₇, ⁻¹/₇)
Answer:
1:4
Step-by-step explanation:
Given
Volume of orange juice = 50ml
Volume of water = 200mL
Required
Ratio of volume of orange juice to water
Ratio = volume of orange juice/volume of water
Ratio =50mL/200mL
Ratio =5/20
Ratio =1/4 or 1:4
Hence the required ratio is 1:4
Answer:
23
Step-by-step explanation:
2^-2 would become 1/2^2 which becomes 1/4.
