Step-by-step explanation:</h2>
The first equation can be rearranged by subtracting <em>y</em> from both sides. This gives you x = 4 - y.
The second equation is x = y - 1
Therefore, as both equations are equal to <em>x</em>, you can say that they are equal to each other, so 4 - y = y - 1.
If you add 1 to each side, you get 5 - y = y
If you add <em>y</em> to each side, you get 5 = 2y
Divide both sides by 2 to get y = 5/2
Now you can substitute 5/2 for y. For example, the second equation becomes x = 5/2 - 1
x is therefore 3/2
This can be written as , which is the final answer.
Answer:
Step-by-step explanation:
Base of the triangle= 37•5m
Height of the triangle= 6•4m
Area of the triangle= 1/2 × base × height
= 1/2 × 37•5 × 6•4
= 120 m^2

Answer:
Step-by-step explanation:
1/4 inch to 3/8 ft = x inches to 1 ft
(1/4) / (3/8) = x / 1
cross multiply because this is a proportion
3/8x = 1/4
x = 1/4 * 8/3
x = 8/12 which reduces to 2/3 inches <==

Answer:
13 or 13.125 you have to look at your notes to see which it is. Personally I would take 13. Try that first.
Step-by-step explanation:
Be careful how you interpret this question. It reads like this.
3:8 :: x:35
In other words, the 8 and 35 females goes together.
Set this up as a proportion
3/8 = x / 35 Cross multiply
3*35 = 8x Combine the left
105 = 8x Switch
8x = 105 Divide by 8
x = 105 / 8 get the answer
x = 13.125 You cannot have 1/8 of a person. So what are you going to do?
You have to round down. x = 13. How close is this
13/35 = 0.371 as apposed to 0.375 which is what 3/8 is.
