The equation is false because the real answer is z5/4. The variable doesn't just disappear.
13/17 is at the lowest because they are both prime numbers.
Given:
The given table represents the ingredient need to make 4 muffins.
To find:
The amount of flour needed to make 12 muffins.
Solution:
We have, the data for 4 muffins.
From the given table it is clear that,
Flour need for 4 muffins = 250 g
Flour need for 1 muffins = 
g
Flour need for 12 muffins = 
g
= 
g
= 
g
So, 750 g flour is need to make 12 muffins.
Therefore, the correct option is D.
We write the equation in the form of directional.
y -1 = 6x ⇔ y = 6x + 1
y - 1 = 3x ⇔ y = 3x + 1
y - 7 = 2x - 6 ⇔ y = 2x - 6 + 7
y = 2x + 1
y - 7 = x - 2 ⇔ y = x - 2 + 7
y = x + 5
Equations cleverly arranged .
Point Q = (0,1)
b factor , not only fits the last equation
In the drawing have engraved points Q and R are tangent linear function appropriate to that point . This graphics solution . y = 3x + 1
Answer b
We check choice by the system of equations , where substitute wartoćsi points Q and R to the model equations linear function
The result of equations confirmed our choice Answer b
