Answer:
5x
Step-by-step explanation:
NOte: it is an expression and not an equation as originally asked.
"Product" means the answer to a multiplication of two numbers.
You are asked to write the answer to 5 and a number being multiplied together.
Let the unknown number be
x
The product is therefore
5x
x
=
5x
The work and answer is shown in the image below. Just set the variables and solve.
Answer:
B and D
Step-by-step explanation:
For a linear equation, the degree is 1.
For y=x² , the degree is 2, so it is not linear.
For y=2x, the degree is 1, so it is linear.
For y=4/x----->xy=4, the degree is 2, so it is not linear.
For y=x/4, we have 4y=x, the degree is still 1, this is also linear.
The correct options are B and D.
I can give you are summary of how to do it. UK geometry is somewhat different to US with regard to symbols used and names.
You need to prove that the 2 triangles BCE and ADE are congruent and then you can say that the sides are also congruent:- Sides BC and AD are equal (opposite sides of a parallelogram) Also < CBE = <ADE ( alternate angles) and < BCE = EAD ( alternate angles) So the triangles are congruent by 2 angles and the corresponding side, ( I think that would be ASA in the US).
9/20. Add 20+24+36=80. Then it's 36/80. Divide both the bottom and the top by 4 and you get 9/20.
