Answer 1
Answer:

Answer: not proportional


Step-by-step explanation:

The constant is called the coefficient of proportionality if one variable is always the product of the other variable and a constant. And the variables are said to be directly proportional.

In the given table , let the variables are proportional then the constant of proportion(k)=(y)/(x)

\Rightarrow\ k=(3)/(2)=1.5

\Rightarrow\ k=(7)/(4)=1.45

⇒ k is not a constant of proportionality.

⇒ the variables x and y are not proportional.

(c) z/3 + z/4 + z/5 = z/4 + z/5 + z/6 + 1$

Answers

For (a)
The resulting equation is
47x/60 = 47x/30
and the solution is 0

For (b)
The resulting equation is
47y/60 = 47y/60 + 1
which is reduced to
47y/60 - 47y/60 = 1
0 = 1 (impossible)

For (c)
The resulting equation is
47z/60 = 37z/60 + z
and the solution is 6

Bradley solved the following equation: 4(5x – 6) = 2(8x + 10) Step Work Justification 1 20x – 24 = 16x + 20 2 4x – 24 = 20 3 4x = 44 4 x = 11 Which of the following has all correct justifications Bradley used to solve this equation? 1. Associative property of addition. 2. Subtraction property of equality. 3. Addition property of equality. 4. Multiplicative inverse. 1. Associative property of addition. 2. Subtraction property of equality. 3. Addition property of equality. 4. Division property of equality. 1. Distributive property. 2. Subtraction property of equality. 3. Addition property of equality. 4. Multiplicative property of equality. 1. Distributive property. 2. Subtraction property of equality. 3. Addition property of equality. 4. Division property of equality.

Answers

Solution:

The equation solved by Bradley is

→4(5x – 6) = 2(8x + 10)

Step Work  

1. 20 x – 24 = 16 x + 20    → [ Distributive property]

Taking variable on one side of equation

2 . 4 x – 24 = 20  → [Subtraction property of equality.]

Taking constant on one side of equation

3 . 4 x = 44 →[Addition property of equality.]

Dividing both sides by 4

4 . x = 11          → [Division property of equality.]

Out of all the four options given ,Fourth option [ 1. Distributive property. 2. Subtraction property of equality. 3. Addition property of equality. 4. Division property of equality ], completely satisfies the work done  in equation.

750 split in to the ratio 7:8

Answers

Given:
total = 750
ratio = 7 : 8

We need to get the ratio of the number to its total

7 + 8 = 15 ; 7/15 and 8/15 is the ratio of the number to its total.

We multiply these ratio to the total of 750

7/15 * 750 = 350
8/15 * 750 = 400

7:8 is equal to 350:400
