To make a specific shade of green paint, Timia mixes 2 cups of blue paint with 10 cups of yellow point. How many cups of yellow
7nadin3 [17]

Answer:

1 cup of blue paint required 5 cups of yellow paints

<em />

Step-by-step explanation:

Given

2 cups of blue = 10 cups of yellow

Required

Determine the number of cups of yellow for 1 cup of blue paint

The given parameter shows a linear relationship between paints of blue and paints of yellow

We have:

2 cups of blue = 10 cups of yellow

Multiply both sides by 0.5

0.5* 2 cups of blue = 0.5* 10 cups of yellow

1 cup of blue = 5 cups of yellow

Hence;

<em>1 cup of blue paint required 5 cups of yellow paints</em>

Can you help me with these questions please?
Marianna [84]

The answers are following

sol1 y = x-1

sol2 y= x+ 7

sol4 y = x+4

Step-by-step explanation:

Solution 1

Here we are going put the point in the given equation ( given in the options)

If the each point satisfies any equation, that will be the relationship between x and y.

Given points are (-3,-4) , (2,1) , (5,4)

Let us take the option C as y = x -1

-4 = -3-1

1 = 2-1

4=5-1

Putting each value in the given equation we get LHS and RHS are same for all points. so, C is the answer.

Similarly, option B is the answer of Solution 2

Each point satisfies the equation y = x +7

Solution 4

y = x +4

You are requested to check the options of Q3 once.
