Answer:
X-y=3. 2x-2y=6. 2y=-2
Y= -1
2x-4y=8. 2x-4y=8 2.x-4.-1=8
2x=4. x=2
Step-by-step explanation:
To find the weight of 1 load of stone, divide 2/3 by 4.
To divide fractions, use keep change flip.
Keep the first fraction the same, change the division sign into a multiplication sign, and flip the second fraction.

The ratio of a : b is 1 : 2
Step-by-step explanation:
A ratio is a relationship between two numbers indicating how many times the first number contains the second number
Ex: If there are eight oranges and six bananas, then the ratio of oranges to bananas is eight to six, and is written as 8 : 6, which is equivalent to the ratio 4 :3 in its simplest form
∵ a + b = 3a
- To find the ratio between a and b find b in terms of a
- Subtract a from both sides
∴ b = 2a
→ a : b
Substitute b by 2a
→ a : 2a
Divide both terms by a
→ 1 : 2
∴ a : b = 1 : 2
The ratio of a : b is 1 : 2

Answer:
x = √(w(w+z))
Step-by-step explanation:
The idea with a right-triangle figure of this sort is that all of the triangles are similar. Here, x is the short side of ∆ABC, and the hypotenuse of ∆BDC. This suggests you want to write a similarity statement involving the short side and hypotenuse.
BC/AC = DC/BC . . . . . short side/hypotenuse
BC² = AC·DC . . . . . . cross multiply
x² = (w+z)w . . . . . . substitute letter values
Taking the square root and rearranging to the form of the applicable answer choice, this is ...
