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)

JulsSmile [24]

Answer:

27 < 5*n +7

n<4

Step-by-step explanation:

Twenty-seven is smaller than five times a number increased by seven


Increase means add

27 < 5*n +7

Subtract 7 from each side

27-7 <5n+7-7

20 < 5n

Divide by 5

20/5 < 5n/5

If two sets are disjoint, then what region represents the union of their complements in a Venn diagram?
katrin [286]
If 2 sets are disjoint means they have not any common element.

Draw a rectangle & inscribe inside this rectangle 2 circles that do not intersect.

cercle₁ ∩ cercle₂ =Ф.
Their complement would be the part of the rectangle - the 2 circles
