Answer:
2:27
Step-by-step explanation:
the original ratio is '4 to 54' but both numbers divide by 2 so the answer is '2 to 27' also known as 2:27
Hello :
x+4y = 28
multiply by : 2
2x+8y =56
same line (same graph)
the system is : <span>Dependent
when the solution is :
x = k .... k in R
y = -1/4 x +7</span>
Answer:
x = -1, 1, -5 , 5.
Step-by-step explanation:
x4 – 26x2 + 25 = 0
Factoring:
(x^2 - 25)(x^2 - 1) = 0
So x^2 - 25 = 0 gives x^2 = 25 and x = +/- 5.
x^2 - 1 gives x^2 = 1 and x = +/- 1.
The ratio of AB to AC and the ratio of AD to DC is 1 : 2 each respectively. They are equivalent ratios.
<h3>Ratios and proportions</h3><h3 />
A ratio means a comparison of two different quantities while proportion is an equality of two ratios.
- AB = 5 in
- AC = 10 in
- AD = 4 in
- DC = 8 in
Ratio of AB to AC = 5 in : 10 in
= 5 / 10
= 1 / 2
= 1 : 2
Ratio of AD to DC = 4 in : 8 in
= 4 / 8
= 1 / 2
= 1 : 2
Therefore, the ratio of AB to AC and the ratio of AD to DC is 1 : 2 each respectively. They are equivalent ratios.
