Y = 5x - 10<br> Can you solve for x
tensa zangetsu [6.8K]

Answer:

x = \frac{1}{5}y + 2     or       x = \frac{y+10}{5}     (Not sure which one is preferred in your case)

Step-by-step explanation:

<u>Key skills needed: Evaluating expressions</u>

1) We are given: y = 5x-10

2) To solve for the x variable, we want to leave the term with "x" by itself.

This means we add 10 to both sides

--> y + 10 = 5x (Since -10 and +10 cancel out to make 0 or nothing)

3) Then we divide by 5 on both sides to get "x" completely by itself.

-----> \frac{y+10}{5} = x

4) You can keep it as is so --> x = \frac{y + 10}{5}

or you can divide "y" by 5 and "10" by 5 and get --> x = \frac{1}{5} y + 2

(I am not sure which form is preferred one is preferred as the teacher matters)

A triangle has sides of 18cm and 32cm. The measurement of the longest side is missing. Ted says that one possibility for the unk
gulaghasi [49]
Since the measurement of the longest side is missing we can use the pythagorean theorem to find the hypotenuse or longest side.

18^2 + 32^2 = c (hypotenuse) ^2
324 + 1,024 = c^2
1,348 = c^2
sqrt 1,348 = c
36.72 = c
i do not agree with ted because when you use the pythagorean theorem you do not get 47cm

this can be proved by
18^2 + 32 ^2 = 47^2
we already know the left side is 1,348
1,348 = 47^2
1,348 does not equal 2,209 which is 47 squared
