Answer:
Value of x =20
Step-by-step explanation:
Given: EF = 9x+14 units , FG = 56 units and EG = 250 units.
Segment Addition Postulates states the following for 3 points that are collinear.
i.e, Let three points A, B and C are collinear and B is between A and C.
i,e AC = AB + BC
By Segment addition postulates; solve for x;
EG = EF + FG
Substitute the given values we get;
250 = 9x + 14 + 56
or
250 = 9x + 70
Subtract 70 on both sides we get;
250 -70 = 9x + 70 -70
Simplify:
180 = 9x
Divide both sides by 9 we get;
Simplify:
x = 20
Therefore, the value of x =20
Answer:
B) 4 tablespoons of salt
Step-by-step explanation:
Here is the correct question: Scott used 1/3 tablespoons of salt to make 1/4 liters of beans. If Scott's recipe is for 1 liter of beans, how much salt will he need to make triple the recipe?
Given is the ratio of salt and beans to make recipe for 1 liter of beans.
Ratio given for 1 liters of beans; .
Now, simplifying the ratio
∴ Ratio for salt and bean in a recipe for 1 liter of beans is .
Next, finding the proportion of salt to make triple the recipe.
Triple the recipe means 3 times of 1 liter of beans, which is 3 liters of beans.
∴ The proportion of salt in 3 liter beans=
Hence, 4 tablespoon of salt is required to make 3 liters of beans or triple the recipe.
