Answer:
Given:
, y =6
To prove: x =7
On substituting the value of y =6 in the equation 7y = 8x -14 to solve for x.
or
42 = 8x -14 ......[1]
Addition Property of equality states that you add the same number to both sides of an equation.
Add 14 to both sides in equation [1];
42+14 =8x -14+14
Simplify:
56 = 8x
or
8x =56 ......[2]
Division Property of equality states that you divide the same number to both sides of an equation.
Divide by 8 to both sides of an equation [2];

Simplify:
x =7 Hence proved!
A two Column proof:
Statement Reason
1. 7y = 8x -14 Given
y= 6
2. 7(6) = 8x -14 Substitution property
3. 42+14 = 8x Addition property of equality
4. 56 =8x Simplify
5. x =7 Division Property of equality
Answer:
15%
Step-by-step explanation:
We have the followign simple interest formula
FV (aka AV)=PV(1+it)
which means that we have
(800+360)=800(1+3i)
1.45=1+3i
.45=3i
.15=i

Answer:
2.33 kg
Step-by-step explanation:
If the baker needs to use 2.327 kilograms of blueberries, we are going to subtract the amount of the packages to the amount he needs and we'll see which is the smallest number.
In the case of 2.3, 2.327 - 2.3 = .027
In the case of 2.42, 2.327 - 2.42 = -0.09
In the case of 2.33, 2.327 - 2.33 = -0.003
In the case of 2.4, 2.327 - 2.4 = -0.07
Therefore, the closest amount to 2.327 is the 2.33 package.
