Answer:
here
Step-by-step explanation:
The tools that were used by ancient mathematicians to make geometric constructions are compasses and straightedges. A compass is a drawing instrument used to draw circles and arcs. The straightedges on the other hand is a tool to check on the accuracy of a straight line.
The answer is first choice.
Ratio is used 4:1 for the table that has 2 sides

Assumptions
-------------------------------------------------------------------------------------------------
Let x be the amount of 25% orange juice
Let y be the amount of 10% orange juice
-------------------------------------------------------------------------------------------------
There are 15 litres of 13% orange juice
-------------------------------------------------------------------------------------------------
x + y = 15
-------------------------------------------------------------------------------------------------
The 15 litres of juice is 13% orange juice
-------------------------------------------------------------------------------------------------
0.25x + 0.1y = 15 x 0.13
0.25x + 0.1y = 1.95
-------------------------------------------------------------------------------------------------
Rewrite the equations and solve for x and y
-------------------------------------------------------------------------------------------------
x + y = 15 ----------------------- (Equation 1)
0.25x + 0.1y = 1.95 ----------- (Equation 2)
(Equation 1):
x + y = 15
x = 15 - y ----------- (Substitute into Equation 2)
0.25 (15 - y) + 0.1y = 1.95
3.75 - 0.25y + 0.1y = 1.95
0.15y = 1.8
y = 18 ÷ 0.15
y = 12 ------------- (substitute into Equation 1)
x + y = 15
x + 12 = 15
x = 15 - 12
x = 3
x = 3 and y = 12

Answer: 3 liters of 25% of orange juice with 12 liters of 10% orange juice
-------------------------------------------------------------------------------------------------
Answer:
24
Step-by-step explanation:
To figure out what the value of y is, we must isolate the variable. To do this, we need to use the division property of equality which says that when you divide on one side of the equal sign, you must also divide on the other side.
8y/8 = y
12/8 = 1.5
This tells us the value of y, so next we have to apply this into the problem
8(1.5) = 12
12 + 12 = 24
24 is your answer
